Romeo Essays (620 words) - English-language Films,

Romeo And Juliet In the play Romeo and Juliet, Shakespeare reveals a complex character, Juliet, who has a multifaceted personality. Even so, the essence of Juliet's identify is her youth. Her inexperience gives her a lovable freshness. This is first demonstrated in the famous balcony scene when she is talking to herself. Her question, "What's in a name?" suggests a very childlike quality. It's her way of paraphrasing the question, "Why?" Children often ask this question without even thinking about it. As the scene progresses, she proposes to Romeo. She is so artless and untraditional in this regard. Nowadays, society has given women more freedom and independence. Back then, a woman proposing marriage was unheard of. Through this encounter between Romeo and Juliet, we see Juliet's innocence in the way she responds to her first true love. Their poetic words are simple yet sincere, sweet words spoken in total honesty from the depths of their souls. New to love, Juliet found it difficult to express her feelings to Romeo. Had he no overheard her private thoughts in Capulet's orchard, Juliet most likely would not have been able to say those things to his face. Later in the play, Romeo says, "Now I have stained the childhood of our joy." He recognized the purity of their love. Perhaps this is why Juliet devotes herself so entirely to him without any doubts. She has childlike faith in him. In that way, her love for him was blind. Ever the optimist, she still believes Friar Lawrence's plan will work despite all the possible catastrophes that could occur. For her, love will always triumph over hate. There's no reason for her to believe otherwise. Her youthful nature is shown again through her impatience. Waiting for the nurse to come back, Juliet is anxious and frustrated. The second the nurse returns, she demands to hear of the news. This shows somewhat of a character flaw as she is only interested in instant gratification. Her inability to wait for long term satisfaction sets the stage for more diaster for the "star-crossed lovers." The nurse comments on this when she says Juliet is "hot", meaning impatient. Juliet has a tendency to rush things; this trait goes hand in hand with her impatience. Romeo and Juliet are already married when their relationship is only a few days old. Eventually, this fault in the couple leads to their untimely demise. Hastiness is an important part of the play. Juliet's line, "It is too rash, too unadvised, too sudden," serves to confirm this. Although she realized this fact, she did nothing to slow down the pace of the relationship. Rebelling against her parents to wed their enemy's son, Juliet was merely following her heart. By that time, she had fallen too much in love with Romeo to give himup. Despite not wanting to disobey her parents, she listened to her instincts and emotions. In her case, it was an unwise decision because her emotions clouded her judgment. Juliet's attributes contrast sharply with those of the nurse, who acts as a foil. Even though the two are extremely close, they are remarkably distinct. For example, Juliet is still dreaming of love whereas the nurse is more enlightened. Juliet is very naive about men, whereas the nurse has "no faith, no honesty in men." The young teen has not perceived anything in her short life to stain the male image in her eyes because of her sheltered existence. Overall, Shakespeare has made Juliet come alive in the sense that she is a person with whom we can identify with. She is like a precious gem, still being refined and polished into a mature adult. That dear imperfection is something we all can relate to. The audience connects with that and for them, she isn't just a fictitious role in an imaginary world. Shakespeare's mastery comes from not only the beautiful poetry or prose, but from his ability to reach out and the touch the audience with characters like Juliet.

How Helium Works essays

How Helium Works essays There is something incredibly special about helium balloons! If you buy one at the circus or fair, you can hold its string and it will ride along above you. If you let go of the string it will fly away until you cannot see it anymore. If you have ever wondered why it flies away, the passages below can help you to figure out the mystery. Helium balloons work using exactly the same law of buoyancy. In this case, the helium balloon that you hold by a string is floating in a "pool" of air. The helium balloon displaces an amount of air (just like a empty bottle displaces an amount of water). As long as the helium plus the balloon is lighter than the air it displaces, the balloon will float in the air. It turns out that helium is a lot lighter than air. The difference is not as great as it is between water and air (a liter of water weighs about 1,000grams, while a liter of air weighs about a gram), but it is significant. Helium weighs 0.1785 grams per liter. Nitrogen weighs 1.2506 grams per liter, and since nitrogen makes up about 80% of the air we breath, 1.25 grams is a good approximation for the weight of liter of air. Therefore, if you were to fill a one-liter soda bottle full of helium, the bottle would weigh about 1 gram less than the same bottle filled with air. That doesn't sound like much - since the bottle weighs more than a gram the bottle will not float. However, in large volumes, the 1-gram per liter difference between air and helium can really add up. This explains why balloons are generally quite large - they have to displace a lot of air to float. So why is helium so much lighter than air? It's because helium atoms are lighter than a nitrogen atom. It has fewer electrons, protons and neutrons than nitrogen atoms do, and that makes it much more lighter. Approximately the same number of atoms of each of the elements fills approximately the same amount o ...

Heart of Algebra Key Strategies for SAT Math

Heart of Algebra Key Strategies for SAT Math SAT / ACT Prep Online Guides and Tips On the newly redesigned 2016 SAT, the math section content is divided into four categories by the College Board: Heart of Algebra, Problem Solving and Data Analysis, Passport to Advanced Math, and Additional Topics in Math. Heart of Algebra accounts for the largest part of the SAT math section (33% of the test), so you need to be well prepared for it. In this post, I’ll be discussing this category's content and question types, working through practice problems, and giving tips on how to ace these questions. Heart of Algebra: Overview Content Covered Just as the name would suggest, Heart of Algebra covers algebra content, but what algebra content specifically? These questions cover: Linear Equations System of Equations Absolute Value Graphing Linear Equations Linear Inequalities and Systems of Inequalities I’ll delve into each one of these content areas below. I’ll explain exactly what you need to know in each area, and I’ll walk you through some practice problems. NOTE: All of the practice problems in this article come from a real College Board SAT practice test (Practice Test #1). I’d recommend you don’t read this article until after you’ve taken Practice Test #1 (so I don’t spoil it for you!). If you haven’t taken Practice Test #1, bookmark this article and come back after you’ve completed it. If you’ve already taken Practice Test #1, then read on! Heart of Algebra Question Breakdown As I mentioned at the start of the article, Heart of Algebra makes up 33% of the math section, which works out to 19 questions. There will be eight in section 3 (the non-calculator math test) and in section 4 (the calculator math test). Heart of Algebra questions vary in presentation. Because there are so many, the College Board needed to mix up how they ask you these questions. You’ll see multiple-choice and grid-in Heart of Algebra questions. You may simply be presented with an equation(s) and need to solve or you might be given a real world scenario as a word problem and need to create an equation(s) to find the answer. The SAT math section presents questions in order of difficulty (defined by how long it takes an average student to solve a problem and the percentage of students who answer the question correctly). You will see Heart of Algebra questions throughout the section: the straightforward, â€Å"easy† ones will appear at the beginning of the multiple choice and grid-ins while the more challenging ones that require you to create an equation or equations to solve will appear towards the end. I’ll give examples of each type of question (easy and hard) as we learn about each content area in the next section. We're on the path to conquering algebra! Content Area Breakdowns Linear Equations Linear equation questions can be presented in a couple of ways. The easier linear equation questions will ask you to solve a linear equation that is given to you. The harder linear equation questions will ask you to write a linear equation to represent the given situation. No Calculator Practice Problems This question is one of the simplest, easiest and most direct Heart of Algebra questions that you’ll see. The question just asks you to solve a linear equation without situating it in a real world situation that would require you to make sense of the context as well as the equation. Answer Explanation: Since $k=3$, one can substitute 3 for k in the equation, which gives ${x-1}/{3}=3$. Multiplying both sides of ${x-1}/{3}=3$ by 3 gives $x-1=9$, and if you add 1 to each side, then the result is $x=10$. D is the correct answer. Tip: If you struggled with this question, you could also solve it by plugging in the answer choices for x and seeing which one worked. Plugging in will work but will take you more time than simply solving the equation. If you solve the equation to find x, you can double check your answer by then plugging it in. If you plug in your answer choice for x, and both sides of the equation are equal, you know you have the right answer! The following question is slightly more challenging since it asks you to create a linear equation to represent the real world scenario it presents. Answer Explanation: There are two ways to approach this problem. Approach 1: The total number of messages sent by Armand is equal to his rate of texting (m texts/hour) multiplied by the 5 hours he spent texting: m texts/hour Ãâ€" 5 hours = $5m$ texts. Similarly, the total number of messages sent by Tyrone is equal to his rate of texting (p texts/hour) multiplied by the 4 hours he spent texting: p texts/hour Ãâ€" 4 hours = $4p$ texts. The total number of messages sent by Armand and Tyrone is equal to the sum of the total number of messages sent by Armand and the total number of messages sent by Tyrone: $5m+4p$. C is the correct answer. Approach 2: Pick numbers and plug them in. For example, I'm going to pick numbers and say Armand sends 3 texts per hour and Tyrone sends 10 texts per hour. Based on the given information, if Armand texts for 5 hours, Armand sent (3 texts per hour)(5 hours) texts or 15 texts; if Tyrone texts for 4 hours, Tyrone sent (10 texts per hour)(4 hours) texts or 40 texts. Therefore, the total number of texts sent by Armand and Tyrone is $15+40=55$ texts. Now, I plug in the numbers I chose to the answer choices and see if the number of texts matches 55 texts, so for answer C, $5(3) +4(10)=15+40=55$ texts. Therefore, C is the correct answer. NOTE: for this question, this strategy was slower, but for more complicated questions, this can be a faster and easier approach. Tip: Take these problems one step at a time. Figure out Armand’s total number of text messages, then figure out Tyrone’s total number of text messages, and then, combine them into one expression. Don’t rush to jump to the final answer. You might make a mistake along the way. Systems of Equations System of equations questions will be presented in similar ways as linear equation questions; however, they’re more difficult because you now have to do more steps and/or create a second equation. The easier system of equation questions will ask you to solve for one variable when you’re given two equations with two variables. The harder system of equation questions will require you to write a system of equations to represent the given situation and then solve for one variable using the equations you created. No Calculator Practice Problems This question is arguably the simplest, easiest and most straightforward systems of equation questions that you’ll see. It sets up the equations for you, and simply asks you to solve for x. Answer Explanation: Subtracting the left and right sides of $x+y=−9$ from the corresponding sides of $x+2y =−25$ gives $(x+2y)−(x+y)=−25−(−9)$, which is equivalent to $y=−16$. Substituting $−16$ for $y$ in $x+y=−9$ gives $x+(−16)=−9$, which is equivalent to $x=−9−(−16) =7$. The correct answer is 7. Tip: Plugging in may be a good option if you’re given this question in the multiple-choice (which isn’t the case here). However, you could have also plugged in your answer to double check your work! Here is another fairly straightforward system of equation question, but it is slightly more difficult since you need to provide the answer for both x and y (which creates more potential for error). Answer Explanation: Adding x and 19 to both sides of $2y−x=−19$ gives $x=2y+19$. Then, substituting $2y+19$ for x in $3x+4y=−23$ gives $3(2y + 19)+4y=−23$. This last equation is equivalent to $10y+57=−23$. Solving $10y+57=−23$ gives $y=−8$. Finally, substituting −8 for y in $2y−x=−19$ gives $2(−8)−x=−19$, or $x=3$. Therefore, the solution $(x, y)$ to the given system of equations is $(3, −8)$. Tip: Plugging in would have also been a quick way to solve this one! When asked to solve for both variables in a system of equation question, always try plugging in! The following is a bit more difficult. Even though you’re given the equations, you still need to determine what the question is asking you (which variable you need to solve for) which is slightly more challenging since it asks you the question using a real world scenario. Also, you need to solve it using mental math (since it’s in the no calculator section). Answer Explanation: To determine the price per pound of beef when it was equal to the price per pound of chicken, determine the value of x (the number of weeks after July 1) when the two prices were equal. The prices were equal when $b=c$; that is, when $2.35+0.25x=1.75+0.40x$. This last equation is equivalent to $0.60=0.15x$, and so $x={0.6}/{0.15}=4$. Then to determine $b$, the price per pound of beef, substitute 4 for $x$ in $b=2.35+0.25x$, which gives $b=2.35+0.25(4)=3.35$ dollars per pound. Therefore, D is the correct answer. Tip: Take your time working through each step. It’s easy to make a small mistake and get the wrong answer. Calculator Practice Problem The following is one of the hardest Heart of Algebra questions. Based on the real world scenario that you’re given in the question, you need to create two equations and then solve them. Answer Explanation: To determine the number of salads sold, write and solve a system of two equations. Let $x$ equal the number of salads sold and let $y$ equal the number of drinks sold. Since the number of salads plus the number of drinks sold equals 209, the equation $x+y=209$ must hold. Since each salad cost 6.50, each soda cost 2.00, and the total revenue was 836.50, the equation $6.50x+2.00y=836.50$ must also hold. The equation $x+y=209$ is equivalent to $2x+2y=418$, and subtracting each side of $2x+2y=418$ from the respective side of $6.50x+2.00y=836.50$ gives $4.5x=418.50$. Therefore, the number of salads sold x was $x={418.50}/{4.50}=93$. Therefore, B is the correct answer. Tip: Take these problems one step at a time. Write out the equation for the total number of salads and drinks sold, then figure out the equation for revenue, and then, solve. Don’t rush it or you might make a mistake. Absolute Value There will typically only be one Absolute Value question in the SAT math section. The question is usually pretty easy and straightforward, but it requires you to know the rules of absolute value to answer it correctly.Anything that is an absolute value will be bracketed with absolute value signs which look like this: || For example, $|-4|$ or $|x-1|$ An absolute value is a representation of distance along a number line, forward or backward. This means that whatever is in the absolute value sign will become positive since it represents distance along a number line and it is impossible to have a negative distance. For example, on the above number line, -2 is 2 away from 0. Anything inside of the absolute value becomes positive. This also means that an absolute value equation will always have two solutions. For example, $|x-1|=2$ will have two solutions $x-1=2$ and $x-1=-2$. Then, you solve each separate equation to find the two solutions, $x=3,-1$. When working on absolute value problems, remember that you need to create two separate solutions the positive and the negative as we did above. Calculator Practice Problem Answer Explanation: If the value of $|n−1|+1$ is equal to 0, then $|n−1|+1=0$. Subtracting 1 from both sides of this equation gives $|n−1|=−1$. The expression $|n−1|$ on the left side of the equation is the absolute value of $n−1$, and, as I just mentioned, the absolute value can never be a negative number since it represents distance. Thus, $|n−1|=−1$ has no solution. Therefore, there are no values for n for which the value of $|n−1|+1$ is equal to 0. D is the correct answer. Tip: Remember the rules of absolute value (it’s always positive!). If you remember the rules, you should get the question right! Graphing Linear Equations These questions test your ability to read a graph and interpret it into $y=mx+b$ form. A quick refresher, $y=mx+b$ is the slope-intercept equation of a line, where m represents the slope and b represents the y-intercept. In these questions, you’ll typically be presented with the graph of a line, and you’ll need to determine what the slope and y-intercept are to write the equation of the line. Calculator Practice Problem Answer Explanation: The relationship between h and C is represented by any equation of the given line. The C-intercept of the line is 5. Since the points $(0, 5)$ and $(1, 8)$ lie on the line, the slope of the line is ${8-5}/{1-0}={3}/{1}=3$. Therefore, the relationship between h and C can be represented by $C=3h+5$, the slope-intercept equation of the line. C is the correct answer. Tip: Have the slope-intercept form ($y=mx+b$) and the slope equation $m={y_2-y_1}/{x_2-x_1}$ memorized. Know what each variable in the equations means. If you know all of this, you should be able to ace any graphing linear equation problem that you’re given. Linear Inequalities and Systems of Linear Inequalities These are arguably the most challenging Heart of Algebra questions because many students struggle when variables are combined with inequalities. If you need a quick but in-depth refresher on inequalities, check out our inequalities guide. These questions typically appear towards the end of the multiple-choice and grid-ins in each section. These questions will be presented as straightforward already set up inequalities (you won’t be asked to create inequalities nor will you be presented with a real world scenario using inequalities). Although they’re presented in a straightforward way, these questions are challenging, and it’s easy to make a mistake, so take your time! Calculator Practice Problems Answer Explanation: Subtracting $3x$ and adding 3 to both sides of $3x−5≠¥4x−3$ gives $−2≠¥x$. Therefore, x is a solution to $3x−5≠¥4x−3$ if and only if x is less than or equal to −2 and x is NOT a solution to $3x−5≠¥4x−3$ if and only if x is greater than −2. Of the choices given, only −1 is greater than −2 and, therefore, cannot be a value of x. A is the correct answer. You could also try to answer this by plugging in the answer choices and seeing which one didn't work. If you plug in A into the inequality, you'd get $3(-1)-5≠¥4(-1)−3$. Simplifying the inequality, you'd get -8≠¥-7, which is not true, so A is the correct answer. Tip Remember the rules of inequalities! Take your time working your way through each step so that you don’t make any mistakes. Also, remember to try plugging in the answer choices to find the correct answer! Let's take a look at another example. Answer Explanation: Since (0, 0) is a solution to the system of inequalities, substituting 0 for x and 0 for y in the given system must result in two true inequalities. After this substitution, y −x + a becomes 0 a, and y x + b becomes 0 b. Hence, a is positive, and b is negative. Therefore, a b. Choice A is correct. Tip: Treat this system of inequalities with four variables the same as you’d treat a system of inequalities with two variables. Remember that if (0,0) is a solution that means that when x=0, y=0.

Strategy #1: Memorize the Rules and Formula You need to know the rules of inequalities, the rules of absolute value, and the formula for the intercept-slope version of a line ($y=mx+b$) to answer those types of algebra questions correctly. Without the rules and formula, these questions are pretty much impossible. If you need more assistance with any of the concepts, check out our in-depth guides to linear equations, systems of equations, absolute value, intercept-slope form, and linear inequalities and systems of inequalities. Strategy #2: Plugging in Answers On the multiple-choice questions, you should always check to see if you can plug in the answer choices to the given equation(s) or inequality to find the correct answer. Sometimes this approach will be much simpler than trying to solve the equation. Even if you find that plugging in answers is slowing you down, you should, at least, consider using it to check your work. Plug in the answer choice that you find and see if it results in a balanced equation or correct inequalities. If it does, you know you have the correct answer! Plug it in! Plug it in! Strategy #3: Plugging in Numbers If plugging in answers isn't a possibility, plugging in numbers is often a possibility such as in question 2 above. When you pick numbers to plug in, in general, I do not recommend using -1, 0, or 1 (as they can result in wrong answers), and make sure to read the question to see what numbers you should pick. For example, in question 2, the numbers represented the number of text messages sent, so you shouldn't use a negative number to represent the number of text messages since it's impossible to send a negative number of text messages. For inequalities this is especially important, often the question will say "the following is true for all $x0$." If that's the case, you can't plug in 0 or -5; you can only plug in numbers greater than 0 since that's the parameter set by the question. Strategy #4: Work One Step At a Time For Heart of Algebra questions, you need to take your time working through each step. These questions can involve 5, 10, 15 steps, and you need to take your time to make sure you don't make a small mistake in step 3 that will result in an incorrect answer. You know your stuff, so don't let small mistakes cost you points! What’s Next?

Health and Long Term Policies and Programs in the Asian Cultures Essay

Health and Long Term Policies and Programs in the Asian Cultures - Essay Example China was worried then that it may have too many children to feed but after twenty-five years, it is now worried that an aging population may have too few workers to provide care services. Health care costs for both China and Japan can be expected to rise exponentially as fewer workers are present within the system to provide for a growing population of older citizens (Kaneda, 2006). Further, the problem of AIDS will certainly be an issue perhaps to the level of some sub-Saharan African nations which have found AIDS to be a growing menace. Human trafficking and the sex trade certainly adds to the problem and while the issue may not be that critical in Japan, it certainly is on the horizon for China and some other lesser developed countries in the Asian region such as Thailand and Burma. The government policies of creating awareness, educating the masses and providing positive social support could certainly help improve the matter (ASIP, 2008). On the other hand, the problem of an aging population may be a more critical one for China due to the devastating economic consequences it can have for the country as it seeks to become the economic superpower of the world. While the government has started to allocate more funds for the care of the elderly, a lot remains to be done and as reported by Kaneda (2006), â€Å"The rate of increase in health care costs has already exceeded the growth of the national economy and individual earnings (Kaneda, 2006, Pg. 1)†. In such a situation, the coming demographic shift for China would only worsen the situation as a whole generation of Chinese reach the age of retirement. It has to be understood that the trend of an aging population is inevitable for many countries and may even become accelerated where mortality rates as well as fertility are declining. However, the governments of Asia are focusing on policies which are geared

Discuss the relevant ethical and legal issues based on the case study Essay

Discuss the relevant ethical and legal issues based on the case study - Essay Example Nevertheless, medication has its confines. Whereas these restrictions may change with developments in science and technology, it is misleading to behave as if medicine can defeat all illnesses and death itself. The cardiopulmonary resuscitation (CPR) public view has been one of over-assurance; this is somewhat because of the incorrect resuscitation portrayal in TV dramas in which it is recognized as an epic event where the patient attains a remarkable recovery. Regrettably, this is not mirrored in the signs of subsistence to discharge. Within hospital cardiac-arrests, normally, less than one in 7 (15%) patients live on. This essay examines the ethical and legal issues of placing DNR adult without informing the patient or the family. The NFR order Expert assistance has been issued by the UK’s Resuscitation Council concerning the usage of advance NFR orders. They affirm that NFR orders must be rendered after contemplation of prime matters: the patient's recognized or ascertainab le desires; the possibility of successfully reviving the breathing and the heart of the patient as well as the patient's human-rights, such as the privilege to life plus the privilege to be uninhibited from demeaning treatment (Herbert 2008). A NFR order designates that cardiopulmonary resurgence will not be instigated during a patient's respiratory or cardiac arrest, but does permit for any other remedial interventions. Nonetheless, some liken having a NFR directive with the removal or denying of other therapeutic interventions that is not the purpose. This absence of precision causes fear amongst the overall public (Kerridge Lowe & Stewart 2009). There has been current public concern concerning the NFR orders usage after a number of cases where patients or even their families have objected that resuscitation directives have been included in their medical records without their consent or knowledge, mainly in the circumstance of old patients, a better example is Mrs Lily scenario . Two concerns have arisen: firstly, that of clandestine decision-making and, secondly, ageism. Following much debate within the media plus including Age Alarm, the Health Department dispensed a memo to every NHS trustasking that chief administrators guaranteed that suitable resuscitation policies that respect patients' privileges were briefed. Some investigations have revealed that, with escalating age, CPR has worse results, nevertheless; a more current study exhibited that oldness was not a noteworthy influence when considering the aftermaths of cardiac-arrest. Corresponding to this, other findings have established that patients above the age of seventy with slight or no co-existing severe ailment were as expected to live as fresher patients. Age, therefore, in itself ought not to be a contra-suggestion to cardiopulmonary resuscitation (Hayward, 2009). Advance directives An 'advance directive' provides patients the lawful right to provide, or deny, assent to particular medical cure s prospectively. Their use must ensure that health experts are sentient of specific patients' desires if their state should worsen and they undergo loss of psychological capacity. The British Medical Association (2000) issued a protocol of practice that specified that competent cognizant adults have a reputable legal entitlement to reject medical processes beforehand and that, where lawful and appropriate, an ’

Police Pursuits of Criminals Essay -- Criminal Crime Police Essays

Police Pursuits of Criminals   Ã‚  Ã‚  Ã‚  Ã‚  There has been a heated debate over the last few years whether police chases are worth the risk of public safety to catch a fleeing criminal. Each year these hot pursuits end in the arrest of thousands of criminals wanted for a wide array of crimes. At the same time it can cause injury and some times even death.   Ã‚  Ã‚  Ã‚  Ã‚  There is a huge misconception that police are out chasing the red-light violator or the burned-out tail light criminal. This is not the case at all. They are protecting the community and chasing serious felons. That is why most cops defend their right to engage in these high-risk pursuits. No police officer wants to try to stop somebody that they believe is good for a crime just to let him walk away. If the person that is being chased is wanted for a crime, not that he is guilty, but just wanted for an investigation, then the police have every right to stop them and to do what is necessary to apprehend them.   Ã‚  Ã‚  Ã‚  Ã‚  There is also another side to police pursuits with its own troubling statistics. We know that when a pursuit begins it usually ends up causing accidents, injuries, and can some times even be fatal. Critics claim that most of these pursuits are unjustified. Some people say that the suspects flee because they don’t have insurance or their license is revoked. They also say most of them are young and act on impulse and make a bad decision to run. Sometimes it ends up killing innocent people that are in the wrong place at the wrong time.   Ã‚  Ã‚  Ã‚  Ã‚  Is the tragic human cost worth the price for high-speed pursuits? On one side of the debate are the people who believe that pursuits should be severely restricted and abolished altogether. They say the police car seems to be the last unregulated weapon in law enforcement’s arsenal. On the other side are the ones sworn to uphold the law and consider pursuits a necessary law enforcement tool. If you go to a no-pursuit law, you are giving a blanket for the criminals to commit any crime they want and law enforcement is not going to be able to do anything about it. They will run every time because they know they will not be chased. If a person fleeing has a chance of hitting pedestrians, then you need to stop that vehicle at all costs.   Ã‚  Ã‚  Ã‚  Ã‚  As the fatalities mount, no one can run from these issues, least of all the cop behind the wheel. It is safe to say ... ...ce department.   Ã‚  Ã‚  Ã‚  Ã‚  The law enforcement community understands the public concerns for safety and has developed better ways to help pursue fleeing criminals in recent years. One of the best tools now is air support. Helicopters can safely patrol from the sky and there is little chance that the vehicle or criminal can get away. The only problem is that it is very expensive to run. Road spikes have also become popular by puncturing the tires and bringing the vehicle to a crawl.   Ã‚  Ã‚  Ã‚  Ã‚  There are many people with different opinions about hot pursuits. The public needs to back the police up on this matter so the criminals know we are not going to tolerate this conduct in our community and when they do they can expect to be caught and punished for their actions. If we allow them to get away with this behavior we are only adding to the chaos that is in our society today. As of now there are no better ways of catching a suspect. If people are concerned about the risks of high-speed pursuits, then they need to contact their public leaders and help with funding for better tools like the helicopter. Until this happens police chases will have to continue to be conducted from the ground.

Microeconomics/Macroeconomics Chapter 1 Questions and Answers

Chapter 1 The Art and Science of Economic Analysis INTRODUCTION THIS CHAPTER HAS TWO PURPOSES: TO INTRODUCE STUDENTS TO SOME OF THE BASIC LANGUAGE OF ECONOMICS AND TO STIMULATE STUDENT INTEREST IN THE SUBJECT. IT CONVEYS TO STUDENTS THAT ECONOMICS IS NOT ONLY FOUND IN THE FINANCIAL SECTION OF THE NEWSPAPER, BUT ALSO IS VERY MUCH A PART OF THEIR EVERYDAY LIVES. BEGINNING WITH THE ECONOMIC PROBLEM OF SCARCE RESOURCES BUT UNLIMITED WANTS, THIS CHAPTER PROVIDES AN OVERVIEW OF THE FIELD AND THE ANALYTICAL TECHNIQUES USED. CONCEPTS INTRODUCED INCLUDE: RESOURCES, GOODS AND SERVICES, THE ECONOMIC ACTORS IN THE ECONOMY, AND MARGINAL ANALYSIS.TWO MODELS FOR ANALYSIS, THE CIRCULAR FLOW MODEL AND STEPS OF THE SCIENTIFIC METHOD, ARE INTRODUCED. THE APPENDIX INTRODUCES THE USE OF GRAPHS. CHAPTER OUTLINE THE ECONOMIC PROBLEM: SCARCE RESOURCES, UNLIMITED WANTS Use PowerPoint slide 3 for the following section Economics is about making choices. The problem is that wants or desires are virtually unlimi ted while the resources available to satisfy these wants are scarce. A resource is scarce when it is not freely available, when its price exceeds zero. Economics studies how people use their scarce resources in an attempt to satisfy their unlimited wants.Use PowerPoint slides 4-9 for the following sections Resources: The inputs, or factors of production, used to produce the goods and services that humans want. Resources are divided into four categories: 1. Labor: Human effort, both physical and mental 2. Capital: †¢ Physical capital: Manufactured items (tools, buildings) used to produce goods and services. †¢ Human capital: Knowledge and skills people acquire to increase their labor productivity. 3. Natural resources: gifts of nature, bodies of water, trees, oil reserves, minerals and animals. These can be renewable or exhaustible. . Entrepreneurial ability: The imagination required to develop a new product or process, the skill needed to organize production, and the willi ngness to take the risk of profit or loss. Payments for resources: Labor–wage; capital–interest; natural resources–rent; entrepreneurial ability–profit. Use PowerPoint slides 10-12 for the following section Goods and Services: Resources are combined to produce goods and services. †¢ A good is something we can see, feel, and touch (i. e. , corn). It requires scarce resources to produce and is used to satisfy human wants. A service is not tangible but requires scarce resources to produce and satisfies human wants (i. e. , haircut). †¢ A good or service is scarce if the amount people demand exceeds the amount available at a price of zero. Goods and services that are truly free are not the subject matter of economics. Without scarcity, there would be no economic problem and no need for prices. Use PowerPoint slide 13 for the following section Economic Decision Makers: There are four types of decision makers: 1. Households 2. Firms 3. Governments 4. The rest of the worldTheir interaction determines how an economy’s resources are allocated. Use PowerPoint slide 14 for the following section Markets: †¢ Buyers and sellers carry out exchanges in markets. †¢ Goods and services are exchanged in product markets. †¢ Labor, capital, natural resources, and entrepreneurial ability are exchanged in resource markets. Use PowerPoint slides 15-16 for the following section A Simple Circular Flow Model: A simple circular flow model in Exhibit 1 describes the flow of resources, products, income and revenue among economic decision makers. The Art of Economic AnalysisUse PowerPoint slide 17 for the following section Rational Self-Interest †¢ Economics assumes that individuals, in making choices, rationally select alternatives they perceive to be in their best interests. †¢ Rational refers to people trying to make the best choices they can, given the available information. †¢ Each individual tries to minimize th e expected cost of achieving a given benefit or to maximize the expected benefit achieved with a given cost. Use PowerPoint slide 18 for the following section Choice Requires Time and Information: Time and information are scarce and therefore valuable.Rational decision makers acquire information as long as the expected additional benefit from the information is greater than its expected additional cost. Use PowerPoint slide 19 for the following section Economic Analysis Is Marginal Analysis †¢ Economic choice is based on a comparison of the expected marginal cost and the expected marginal benefit of the action under consideration. †¢ Marginal means incremental, additional, or extra. †¢ A rational decision maker changes the status quo if the expected marginal benefit is greater than the expected marginal cost.Use PowerPoint slides 20-21 for the following section Microeconomics and Macroeconomics †¢ Microeconomics: The study of individual economic choices (e. g. , your economic behavior). †¢ Macroeconomics: The study of the performance of the economy as a whole, as measured, for example, by total production and employment. †¢ Economic fluctuations: The rise and fall of economic activity relative to the long-term growth trend of the economy; also called business cycles. Use PowerPoint slide 22 for the following section The Science of Economic AnalysisThe Role of Theory: An economic theory is a simplification of economic reality that is used to make predictions about the real world. An economic theory captures the important elements of the problem under study. Use PowerPoint slides 23-26 for the following section The Scientific Method: A four-step process of theoretical investigation: 1. Identify the question and define relevant variables. 2. Specify assumptions: †¢ Other-things-constant assumption: Focuses on the relationships between the variables of interest, assuming that nothing else important changes (i. e. , ceteris paribu s). Behavioral assumptions: Focus on how people will behave (i. e. , in their rational self-interest). 3. Formulate a hypothesis, a theory about how key variables relate to each other. 4. Test the hypothesis. Compare its predictions with evidence. The theory is then either rejected, accepted, or modified and retested. Use PowerPoint slide 27 for the following section Normative vs. Positive †¢ A positive economic statement concerns what is; it can be supported or rejected by reference to facts. †¢ A normative economic statement concerns what should be; it reflects an opinion and cannot be shown to be true or false by reference to the facts.Economists Tell Stories Use PowerPoint slide 28 for the following section CaseStudy: A Yen for Vending Machines Use PowerPoint slide 29 for the following section Predicting Average Behavior: The task of an economic theory is to predict the impact of an economic event on economic choices and, in turn, the effect of these choices on particu lar markets or on the economy as a whole. Economists focus on the average, or typical, behavior of people in groups. Use PowerPoint slides 30-31 for the following section Some Pitfalls of Faulty Economic Analysis The fallacy that association is causation: The fact that one event precedes another or that two events occur simultaneously does not mean that one caused the other. †¢ The fallacy of composition: The incorrect belief that what is true for the individual, or the part, is true for the group, or the whole. †¢ The mistake of ignoring secondary effects: (unintended consequences of policy) If Economist Are So Smart, Why Aren’t They Rich? Use PowerPoint slides 32-33 for the following section CaseStudy: College Major and Annual Earnings Appendix: Understanding GraphsUse PowerPoint slides 34-39 for the following section Drawing Graphs †¢ Origin: The point of departure, the point from which all variables are measured. †¢ Horizontal axis: The value of the x variable increases as you move along this axis to the right of the origin; a straight line to the right of the origin. †¢ Vertical axis: The value of the y variable increases as you move upward and away from the origin; a straight line extending above the origin. †¢ Within the space framed by the axes, you can plot possible combinations of the variables measured along each axis. †¢ Graph: A picture showing how variables relate. Time-series graph: Shows the value of one or more variables over time. †¢ Functional relation: Exists between two variables when the value of one variable depends on the other variable (e. g. , the value of the independent variable determines the value of the dependent variable). †¢ Types of relationships between variables: – Positive, or direct, relation: As one variable increases, the other variable increases. – Negative, or inverse, relation: As one variable increases, the other variable decreases. – Independen t, or unrelated relation: As one variable increases, the other variable remains unchanged or unrelated.Use PowerPoint slides 40-46 for the following section The Slopes of Straight Lines †¢ The slope of a line measures how much the vertical variable (y) changes for each 1-unit change in the horizontal variable (x). †¢ The slope of a line is a convenient device for measuring marginal effects. Slope reflects the change in y for each one unit change in x. †¢ The slope of a line does not imply causality but indicates a relation between the variables. †¢ The slope of a line is the change in the vertical distance divided by the increase in the horizontal distance. The slope of a line depends on how units are measured; the mathematical value of the slope depends on the units of measurement in the graph. †¢ The slope of a straight line is the same everywhere along the line. †¢ The slope of a curved line varies from one point to another along the curve. †¢ I f the slope is: – Positive: There is a positive or direct relation between the variables. – Negative: There is a negative or inverse relation between the variables. – Zero or assumed infinite: There is no relation between the variables; they are independent or unrelated.Use PowerPoint slides 47-48 for the following section The Slope, Units of Measurement, and Marginal Analysis The Slopes of Curved Lines Curve Shifts: A change in an underlying assumption is expressed by a shift in the curve. Chapter SUMMARY ECONOMICS IS THE STUDY OF HOW PEOPLE CHOOSE TO USE THEIR SCARCE RESOURCES TO PRODUCE, EXCHANGE, AND CONSUME GOODS AND SERVICES IN AN ATTEMPT TO SATISFY UNLIMITED WANTS. THE ECONOMIC PROBLEM ARISES FROM THE CONFLICT BETWEEN SCARCE RESOURCES AND UNLIMITED WANTS. IF WANTS WERE LIMITED OR IF RESOURCES WERE NOT SCARCE, THERE WOULD BE NO NEED TO STUDY ECONOMICS.Economic resources are combined in a variety of ways to produce goods and services. Major categories of re sources include labor, capital, natural resources, and entrepreneurial ability. Because economic resources are scarce, only a limited number of goods and services can be produced with them. Therefore, goods and services are also scarce, so choices must be made. Microeconomics focuses on choices made in households, firms, and governments and how these choices affect particular markets, such as the market for used cars. Choice is guided by rational self-interest.Choice typically requires time and information, both of which are scarce and valuable. Whereas microeconomics examines the individual pieces of the puzzle, macroeconomics steps back to consider the big picture—the performance of the economy as a whole as reflected by such measures as total production, employment, the price level, and economic growth. The 2008-2009 recession illustrates economic fluctuations, the rise and fall of economic activity relative to the long-term growth trend of the economy. Economic fluctuatio ns are also called business cycles. These cycles will be a major topic in the macroeconomics course.Economists use theories, or models, to help understand the effects of an economic change, such as a change in price or income, on individual choices and how these choices affect particular markets and the economy as a whole. Economists employ the scientific method to study an economic problem by (a) formulating the question and isolating relevant variables, (b) specifying the assumptions under which the theory operates, (c) developing a theory, or hypothesis, about how the variables relate, and (d) testing that theory by comparing its predictions with the evidence.A theory might not work perfectly, but it is useful as long as it predicts better than competing theories do. Positive economics aims to discover how the economy works. Normative economics is concerned more with how, in someone’s opinion, the economy should work. Those who are not careful can fall victim to the fallac y that association is causation, to the fallacy of composition, and to the mistake of ignoring secondary effects. The appendix to this chapter deals with the construction and interpretation of graphs. TEACHING POINTS 1.THIS COURSE WILL PROVIDE THE FIRST EXPOSURE TO THE ECONOMIC WAY OF THINKING FOR MANY OF YOUR STUDENTS. ALTHOUGH IT SEEMS NATURAL TO YOU, ECONOMIC ANALYSIS PRESENTS A FORMIDABLE CHALLENGE TO MANY STUDENTS. YOU MAY WISH TO CONSIDER PRESENTING ECONOMICS AS ONE OF MANY APPROACHES TO DESCRIBING HUMAN BEHAVIOR RATHER THAN AS A BODY OF ESTABLISHED DOCTRINES. INTRODUCING A TOPIC WITH RELEVANT QUESTIONS TO WHICH ECONOMICS PROVIDES AN ANSWER GENERALLY ENHANCES STUDENT INTEREST IN ECONOMICS. SUCH QUESTIONS APPEAR AT THE BEGINNING OF EACH CHAPTER. 2. Students are generally eager and very fresh at the beginning of the semester.Chapters 1 and 2 can be assigned during the first week, and you can move almost immediately into discussions of production possibilities, the idea of opport unity cost, the use of marginal analysis, and comparative advantage (see Chapter 2). It should also be easy to meld a discussion of the points contained in the Chapter 1 Appendix with the analytics of Chapter 2. 3. One point to stress in discussing the role and importance of economic analysis is that, while individual responses to changes in an economic environment are not always predictable, the aggregate response often is.The use of such knowledge is valuable in virtually any context in which individuals, households, firms, resource owners, and so on, are faced with changing opportunities and costs. You might use some examples to illustrate this, such as what is the predicted response to a tax on gasoline and who ends up paying for the tax or the impact of a tax refund on consumer behavior. 4. From a purely analytical perspective, the most important concept introduced in this chapter is the idea that decisions are made on the basis of marginal analysis.You might stress that margin al analysis is a cornerstone of economics. 5. Some terminology in the text may deviate from your own lecture notes. If you intend to use any of the Test Banks, try to mention deviations between the text’s usage and the terms you use in your lectures. For example, the text uses the word resources whereas you might use factors of production in your lecture notes. 6. Some students think that economics is synonymous with business. You may wish to explain the difference, because many of your students will be studying business administration. . Many students will be apprehensive about the mathematics used in the course. A good way for students to master the few mathematical tools needed in class is by through application and by using the Study Guides and the online materials. It is essential for students to become comfortable with reading and shifting graphs as well as dividing fractions. The appendix to Chapter 1 provides a good foundation for the tools needed. 8. Many beginning s tudents do not understand what economists mean by the statement â€Å"consumers are rational. It is helpful to emphasize that rationality does not imply that all consumers must be identical or that all consumers make â€Å"good† decisions all the time. Individuals can have dramatically different tastes for goods and service and yet all can be considered rational. ANSWERS TO End-of-Chapter Questions and exercises ANSWERS TO QUESTIONS FOR REVIEW 1. (Definition of Economics) What determines whether or not a resource is scarce? Why is the concept of scarcity important to the definition of economics? A resource is scarce when the amount people desire exceeds the amount available at a price of zero.The concept of scarcity is important to the definition of economics because scarcity forces people to choose how they will use their resources in an attempt to satisfy their unlimited wants and desires. Economics is about making choices. Without scarcity there would be no economic probl em, and therefore no need to choose between competing wants and desires. 2. (Resources) To which category of resources does each of the following belong? a. A taxi b. Computer software c. One hour of legal counsel d. A parking lot e. A forest f. The Mississippi River g.An individual introducing a new way to market products on the Internet. a. capital; a manufactured item employed to produce a service. b. capital; a manufactured item employed to produce a good. c. labor; human effort. d. capital and natural resources; the parking lot is on a natural resource (land), but the land has undergone capital improvement in the form of leveling and paving. e. natural resource. f. natural resource. g. entrepreneurial ability. 3. (Goods and Services) Explain why each of the following would not be considered â€Å"free† for the economy as a whole: a.Food vouchers b. U. S. aid to developing countries c. Corporate charitable contributions d. Noncable television programs e. Public high schoo l education aEven if food vouchers allow individuals to â€Å"purchase† food at no cost, producing the food in the first place uses resources and hence has a cost. b. U. S. aid, while free to the recipient country, involves costs to the United States because the aid requires the use of U. S. resources to assist developing countries. c. The corporation (and its owners) pays for these gifts. d. This is perhaps the most interesting example. Free† TV is paid for by consumers through the higher prices of the products advertised there. The cost of advertising is passed along to consumers. e. Public high school education is paid for by citizens, either through taxes or borrowing. 4. (Economic Decision Makers) Which group of economic decision makers plays the leading role in the economic system? Which groups play supporting roles? In what sense are they supporting actors? The main decision makers are households, with firms, governments, and the rest of the world serving as supp orting actors.Households are considered to be the lead actors since they supply resources used in production, and demand goods and services produced by other actors. Firms, governments, and the rest of the world are supporting actors because they demand the resources that households supply and use them to produce and supply the goods that households demand. 5. (Micro versus Macro) Determine whether each of the following is primarily a microeconomic or a macroeconomic issue: a. What price to charge for an automobile b. Measuring the impact of tax policies on total consumer spending in the economy c.A household’s decisions about what to buy d. A worker’s decision regarding how much to work each week e. Designing a government policy to increase total employment Microeconomics is the study of the individual economic behavior of decision-making units in the economy, whereas macroeconomics studies the performance of the economy as a whole. a. Microeconomic issue; it refers t o the price of an individual good. b. Macroeconomic issue; it refers to the economy as a whole. c. Microeconomic issue; it refers to the decision of one individual household. . Microeconomic issue; it refers to the decisions of one worker. e. Macroeconomic issue; it refers to the economy as a whole. 6. (Micro versus Macro) Some economists believe that in order to really understand macroeconomics, you must first understand microeconomics. How does microeconomics relate to macroeconomics? Microeconomics studies the behavior and choices made by individuals. The behavior and choices made by these individuals is added together to determine the economy–wide(or macroeconomic(measures, such as total production and unemployment.Microeconomics studies the individual pieces of the economic puzzle; macroeconomics fits those pieces together. 7. (Normative versus Positive Analysis) Determine whether each of the following statements is normative or positive: a. The U. S. unemployment rate w as below 10. 0 percent in 2010. b. The inflation rate in the United States is too high. c. The U. S. government should increase the minimum wage. d. U. S. trade restrictions cost consumers $40 billion annually. A positive statement is a statement about what is. It can be supported or rejected by reference to facts.A normative statement concerns what someone thinks ought to be. It is an opinion and can't be shown to be true or false by reference to facts. a. Positive. Either the unemployment rate was below 10. 0 percent or it was not. The validity of the statement can be checked with appropriate data. b. Normative. There is no objective measure of when the inflation rate is high and when it is not. The statement reflects someone’s opinion of what rate is too high. c. Normative. The word â€Å"should† is usually an indication of an opinion–a normative statement. d. Positive.In principle, the cost of trade restrictions could be measured. Measurement does not involv e opinions 8. (Role of Theory) What good is economic theory if it can’t predict the behavior of a specific individual? This question highlights the fact that economics, like all social sciences, attempts to describe and explain human behavior. In doing so, it cannot measure and control for all factors influencing behavior. The result is that the behavior of a specific individual cannot be explained or predicted, but the behavior of groups of individuals can be.We cannot, for example, predict any particular individual’s buying response to a sale. We can, however, predict what kind of total selling volume will occur because of a sale. Answers to Problems and Exercises 9. (Rational Self-Interest) Discuss the impact of rational self-interest on each of the following decisions: a. Whether to attend college full time or enter the workforce full time b. Whether to buy a new textbook or a used one c. Whether to attend a local college or an out-of-town college a. Individuals wi ll compare the expected benefits of attending college full time with the expected costs.One benefit might be that the individual’s stock of knowledge and productivity will grow, and so will his or her wage. Costs include not only tuition, but also the wages that could have been earned by working instead of attending college full time. If the expected benefits outweigh the costs, then the rational person will choose to go to college full time. b. Individuals will compare the expected benefits of a new textbook with the higher costs of purchasing a new textbook. Benefits include not being confused by other students’ markings in the book and a higher resale value.However, the out-of-pocket cost of a new book will be higher than the cost of a used book. If the expected benefits outweigh the costs, then a rational person will purchase the new textbook. c. Individuals will compare the expected benefits and costs associated with both colleges under consideration and will choo se the college at which the difference between benefits and costs is greater. The costs of attending an out-of-town college may include greater travel costs and phone bills and benefits such as learning about a different region. 10. Rational Self-Interest) If behavior is governed by rational self-interest, why do people make charitable contributions of time and money? Rational self-interest is not blind materialism, pure selfishness, or greed. Rational self-interest means we choose the option that maximizes expected benefits with a given cost. People will give more to charities when the contribution is tax deductible. The lower the personal cost of helping others the more we are willing to help and contribute.. 11. (Marginal Analysis) The owner of a small pizzeria is deciding whether to increase the radius of delivery area by one mile.What considerations must be taken into account if such a decision is to increase profitability? By increasing its delivery radius, the store will have greater sales. However, these marginal revenues must be balanced against the additional costs incurred, such as greater consumption of pizza ingredients, more gasoline for the delivery truck, and possibly the need to hire additional labor and increase advertising. 12. (Time and Information) It is often costly to obtain the information necessary to make good decisions. Yet your own interests can best be served by rationally weighing all options available to you.This requires informed decision making. Does this mean that making uninformed decisions is irrational? How do you determine how much information is the right amount? Rational decision makers will continue to acquire information as long as the benefit of the additional information exceeds the additional costs. Oftentimes we are willing to pay others to gather and digest the information for us. 13. (CaseStudy: A Yen for Vending Machines) Do vending machines conserve any resources other than labor? Does your answer offer any add itional insight into the widespread use of vending machines in Japan?Vending machines, in addition to being labor saving, also conserve space and time. Given the population density of Japan and the limited â€Å"free time† of the typical Japanese worker, vending machines can be expected to be popular among both sellers and buyers in Japan. 14. (CaseStudy: A Yen for Vending Machines) Suppose you had the choice of purchasing identically priced lunches from a vending machine or at a cafeteria. Which would you choose? Why? Different students will answer this question in different ways, but the key point is that non-monetary factors affect decision making.For example, students who opt for the cafeteria instead of the vending machine may, for example, do so because of the impersonal nature of the machine and the desire to â€Å"socialize† the eating experience. 15. (Pitfalls of Economic Analysis) Review the discussion of pitfalls in economic thinking in this chapter. Then id entify the fallacy, or mistake in thinking, in each of the following statements: a. Raising taxes always increases government revenues. b. Whenever there is a recession, imports decrease. Therefore, to stop a recession, we should increase imports. . Raising the tariff on imported steel helps the U. S. steel industry. Therefore, the entire economy is helped. d. Gold sells for about $1,000 per ounce. Therefore, the U. S. government could sell all the gold in Fort Knox at $1,000 per ounce and reduce the national debt. a. This assertion is a mistake because the secondary effects of taxes on production and the labor supply are ignored. If the tax rate were raised to 100 percent, for example, no one would want to work or produce. b. This is the fallacy that association implies causation.It is more likely that recession causes a change in imports than the other way round. c. This is a fallacy of composition. True, the tariff may help the steel industry. But it hurts purchasers of steel, in cluding the automobile and construction industries. The overall effect on the economy is unclear. d. This is the fallacy of composition, because attempts to sell so much gold at once would push down the price of gold. 16. (Association Versus Causation) Suppose I observe that communities with lots of doctors tend to have relatively high rates of illness. I conclude that doctors cause illness.What’s wrong with this reasoning? The causality is undoubtedly in the other direction; that is, doctors will tend to locate where there is a lot of disease and therefore a greater need for medical care. 17. (CaseStudy: College Major and Annual Earnings) Because some college majors pay nearly twice as much as others, why would students pursuing their rational self-interest choose a lower paying major? Students select college majors for a variety of reasons, and the expected pay is only one of them. Some students may have a special interest in lower-paying fields, such as philosophy, religio n, or social work.Some students may not have the aptitude to succeed in the higher-paying majors, such as engineering, mathematics, or computer science. And many students, when they select a major, may simply be unaware of the pay differences based on college major. 18. (Global Economic Watch) Select Global Issues in Context and in the Basic Search box at the top of the page, enter the phrase â€Å"selfish. † On the Results page, scroll down to the Magazines section. Choose the red link to View All. Scroll down to click on the link for the December 8, 2008, article â€Å"Going Green for Selfish Reasons. Are the companies described acting out of rational self-interest? The article indicates that, although the companies' actions may help the environment, the companies are primarily motivated to save costs, an example of rational self-interest. 19. (Global Economic Watch) Select Global Issues in Context and in the Basic Search box at the top of the page, enter either the term à ¢â‚¬Å"microeconomic† or the term â€Å"macroeconomic. † Choose one of the resources and write a summary in your own words. Especially emphasize how the resource is an example of microeconomics or macroeconomics.Student answers will vary, but should demonstrate understanding of the definitions of microeconomics and macroeconomics. Answers to Appendix Questions 1. (Understanding Graphs) Look at Exhibit 5 and answer the following questions: a. In what year (approximately) was the unemployment rate the highest? In what year was it the lowest? b. In what decade, on average, was the unemployment rate highest? In what decade was it lowest? c. Between 1950 and 1980, did the unemployment rate generally increase, decrease, or remain about the same? a. In 1931 the unemployment rate reached its highest point, 25 percent.In 1942 it reached its lowest, approximately 1 percent. b. Unemployment was the highest in the decade of the 1930s and lowest in the decade of the 1900s. c. Between 1950 and 1980, unemployment generally increased. 2. (Drawing Graphs) Sketch a graph to illustrate your idea of each of the following relationships. Be sure to label each axis appropriately. For each relationship, explain under what circumstances, if any, the curve could shift: a. The relationship between a person’s age and height b. Average monthly temperature in your home town over the course of a year c.A person’s income and the number of hamburgers consumed per month d. The amount of fertilizer added to an acre of land and the amount of corn grown on that land in one growing season e. An automobile’s horsepower and its gasoline mileage (in miles per gallon) a. In the years between birth and 15, you would expect a person’s height to increase as his or her age increased. After age 15 or so, height would remain constant. [pic] b. The average monthly temperature in your home town over the course of a year varies with the seasons. [pic]Seasons c.In the fol lowing example drawn, the number of hamburgers consumed per month will rise at first as a person's income increases. (The curve is steeply upward sloping from the origin to an income of $10,000). However, after a certain income level, there will be less and less of a rise in the number of hamburgers consumed per month. (The curve is still upward sloping but is flattening between an income of $10,000 and $20,000. ) Then, as income rises further, this consumer will decide to try other foods and actually buys fewer hamburgers per month. (The curve begins to slope downward after an income of $20,000 is reached. ) pic] d. As you add more fertilizer, you expect to produce more corn per acre up to a point of saturation. An acre of land will have some finite limit on what it can produce in one growing season, no matter how much fertilizer is added! [pic] e. As a car is engineered to be more powerful with more horsepower, you would expect it to use more gasoline and to get lower mileage per gallon of gasoline. [pic] 3. (Slope) suppose you are given the following data on wage rates and number of hours worked: | | |Hours Worked | | |Hourly | | |Point |Wage |Per Week | a |$0 |0 | |b |5 |0 | |c |10 |30 | |d |15 |35 | |e |20 |45 | |f |25 |50 | a. Construct and label a set of axes and plot these six points. Label each point a, b, c, and so on. Which variable do you think should be measured on the vertical axis, and which variable should be measured on the horizontal axis? b. Connect the points. Describe the resulting curve. Does it make sense to you? c. Compute the slope of the curve between points a and b.Between points b and c. Between points c and d. Between points d and e. Between points e and f. What happens to the slope as you move from point a to point f? a. It is conventional in economics to measure prices on the vertical axis. Here the wage rate is the price of an hour of labor, so it goes on the vertical axis. Hours worked is measured on the horizontal axis. B. THE GRAPH SHOWS THAT AT VERY LOW WAGE RATES, THE PERSON CHOOSES NOT TO WORK AT ALL. IT’S JUST NOT WORTH HER WHILE. HOWEVER, ONCE THE WAGE REACHES $10 PER HOUR, SHE BEGINS TO OFFER HER TIME IN THE LABOR MARKET BY BEING WILLING TO WORK 30 HOURS PER WEEK.AT HIGHER AND HIGHER WAGE RATES, SHE IS WILLING TO WORK MORE AND MORE HOURS. c. THE SLOPE IS MEASURED BY THE VERTICAL CHANGE THAT RESULTS FROM A GIVEN CHANGE ALONG THE HORIZONTAL AXIS. From point a to point b, the vertical change (wage) is 5, and the horizontal change (hours worked) is zero. Slope is 5/0 = assumed infinity. From point b to point c, the vertical change (wage) is 5, and the horizontal change (hours worked) is 30. Slope is 5/30 = +1/6. From point c to point d, the vertical change (wage) is 5, and the horizontal change (hours worked) is 5. Slope is 5/5 = +1.From point d to point e, the vertical change (wage) is 5, and the horizontal change (hours worked) is 10. Slope is 5/10 = +1/2. From point e to point f, the vertica l change (wage) is 5, and the horizontal change (hours worked) is 5. Slope is 5/5 = +1. A change in the steepness of the curve indicates a change in slope. As the curve becomes steeper, the rate of increase in hours of work (slope) is increasing. The shape of the curve indicates that as the curve flattens, the rate of increase in hours of work (slope) is decreasing. ———————– d a b c e f
