dell's value added

Dell's value added is only $15 billion, even though US consumers spend $50 billion annually on Dell computers. WHY? because Dell receives $45 from 3rd party retailers (i.e. Walmart, BestBUY) and $35 from direct buyers. Dell pays its suppliers (foreign producers) $30 billion. 45-30 = 15- the direct buyers do no count as value added

7. Maimonides, a twelfth century scholar, said, "Twenty-five children may be put in the charge of one teacher. If the number in the class exceeds twenty-five but is not more than forty, he should have an assistant to help with the instruction. If there are more than forty, two teachers must be appointed." Israel follows Maimonides's rule in determining the number of teachers for each school. How could you use Maimonides's rule to study the effect of teacher-student ratios on student achievement?

Maimonides's rule generates a natural experiment to study of the effect of class size. Suppose School A has 40 third-graders and School B has 41. Following Maimonides's rule, School A would have one 40-student class while School B would have one 20-student class and one 21-student class. Everything else equal, if smaller classes improve achievement then we should expect to see higher test scores in School B.

What does it mean to say that economists use the scientific method? How do economists distinguish between models that work and those that don't?

The scientific method is the name for the ongoing process that economists and other scientists use to develop models of the world, test those models with data and evaluate how well they predict or describe behavior. While this process may not reveal the 'true' model of the world, it does help in identifying models that are useful in understanding the world. In order to decide whether models make accurate predictions or not, economists test them against real-world data. Data are facts, measurements, or statistics that describe the world. This process of testing models against data is called empiricism.

what does it mean to say that economists use the scientific method? How do economists distinguish between models that work and those that don't?

The scientific method requires hypothesis testing. Experiments test hypotheses and ultimately prove them right or wrong. Based on this acceptance or rejection of a hypothesis, scientists go back to their original theories and revise them as needed. This is the gist of the scientific method. to distinguish, they make a hypothesis using data and then test it

During expenditure what do we do with all of the unsold items?

Suppose the country of Burondo is one of the poorest countries in the world. Its economy is heavily reliant on income from the export of oil. There are only two​ oil-extracting companies in Burondo. Both are owned by the government. A large part of the earnings from oil exports goes toward financing the​ president's lifestyle and entourage. Burondo has not had a single democratic election ever since it gained independence 50 years ago. Although Burondo is said to have abundant oil​ resources, only a small proportion is extracted every year because the extraction process is so inefficient. Transporting goods in and out of the country is​ costly, as Burondo is surrounded by lofty mountain ranges. School enrollment in this country is very low and as a​ result, most of the adult population is illiterate. Life expectancy is also quite low. Agriculture is collectivized in Burondo and so food shortages are common in the country. Using the information​ given, distinguish between the fundamental and proximate causes of prosperity​ (or its​ absence) in Burondo.

Suppose that there are only two small countries in the​ world: Ascot, with a population of 36,400 ​people, and​ Delwich, with a population of 28,000 people.​ Ascot's GDP is equal to ​$180 million while​ Delwich's GDP is ​$270 million.​ Delwich's GNP has been estimated to be equal to ​$290 million. The revenue earned by firms that operate in Delwich but are headquartered in Ascot is equal to ​$40 million. Given the data​ above, Ascot's GNP is ​$_______million.

Ascot's GNP is computed from its GDP ​($180 ​million) by adding in the revenue earned by​ Ascot-owned firms that operate in Delwich ​($40 million) and subtracting the revenue earned by​ Delwich-owned firms that operate in Ascot. The revenue of those​ Delwich-owned firms operating in Ascot is found as a residual from the given facts about the Delwich​ economy: Delwich GNP​ = Delwich GDP​ + Revenue of​ Delwich-owned firms in Ascot− Revenue of​ Ascot-owned firms in Dulwich ​$290 ​= ​$270 ​+ Revenue of​ Delwich-owned firms in Ascotminus−​$40 ​(in millions) ​$290−​$270 ​+ ​$40 ​= Revenue of​ Delwich-owned firms in Ascot ​$60 ​= Revenue of​ Delwich-owned firms in Ascot With this​ variable, the GNP for Ascot can be​ computed: Ascot GNP​ = Ascot GDP​ + Revenue of​ Ascot-owned firms in Delwich− Revenue of​ Delwich-owned firms in Ascot Ascot GNP​ = ​$180 ​+ ​$40−​$60 Ascot GNP​ = ​$160 million The per capita GDP in Ascot is simply its GDP of ​$180million divided by its population of 28,600. This​ value, rounded to the nearest​ dollar, is ​$6,294.

What is meant by empiricism? How do empiricists use hypotheses?

Empirical evidence is a set of facts established by observation and measurement, which are used to evaluate a model. Empiricism refers to the practice of using data to test economic models. When conducting empirical analysis, economists refer to a model's predictions as hypotheses. Hypotheses are predictions (typically generated by a model) that can be tested with data.

what is it meant by empiricism? How does empiricists use hypothesis?

Empiricism is using data to study the world around us. it begins with the hypothesis that there is an objective reality independent of humanity and we may use inductive logic to learn about this reality through our senses. We can experiment and test the validity of our ideas. The scientific method is a method of empirical testing to prevent common fallacies and errors. Empiricism does not assume a prior knowledge.

6. The chapter shows that as a general rule people with more education earn higher salaries. Economists have offered two explanations of this relationship. The human capital argument says that high schools and colleges teach people valuable skills and employers are willing to pay higher salaries to attract people with those skills. The signaling argument says that college graduates earn more because a college degree is a signal to employers that a job applicant is diligent, intelligent, and persevering. How might you use data on people with two, three, and four years of college education to shed light on this controversy?

If the human capital explanation is correct, then we might expect to find that people who attend college but do not graduate earn salaries that are close to what college graduates earn. Consider the extreme case of people who drop out of college the week before graduation. It is very unlikely that they would have improved their job skills much in that last week. The human capital school of thought would suggest that they should therefore earn roughly the same salaries as college graduates. On the other hand, the signaling school of thought would argue that these people should earn significantly less than college graduates. Employers would interpret their failure to graduate as a signal they are not as diligent or persevering as people who see their college educations through to the end. There is substantial literature on what is often called the "sheepskin effect" (college diplomas used to be written on sheepskin; Notre Dame continued to use sheepskin until 2012). That literature suggests that human capital and signaling both contribute to the returns to education that we observe in the data.

Consider a ​$100 increase in GDP per capita. In​ 2012, Niger had a GDP per capita of approximately ​$800​, and the United States had a GDP per capita of ​$50,700. Calculate the corresponding growth rates for these two countries. ​Niger's growth rate is _____percent, and the U.S. growth rate is ________ percent. ​(Round your responses to two decimal places​.) ​Thus, ________ started out with a lower base and had a _________ growth rate.

In​ 2012, Niger had a GDP of only​ $13.4 billion, and a population of 16.9​ million, resulting in a per capita GDP of approximately ​$800800. An increase in per capita GDP of just ​$100100 ​(which hardly makes Niger a rich​ country) would result in a GDP growth rate​ of: StartFraction $ 900 minus $ 800 Over $ 800 EndFraction equals 12.50 % $900−$800 $800=12.50% By​ contrast, a ​$100100 increase in U.S. GDP per capita​ (from ​$50 comma 70050,700 to ​$50 comma 80050,800​) reflects a GDP growth rate of only 0.200.20 percent. niger, higher

Some studies have found that people who owned guns were more likely to be killed with a gun. Do you think this study is strong evidence in favor of stricter gun control laws? Explain.

Not necessarily. It is quite possible that people who thought they were at risk (perhaps because they live in dangerous neighborhoods) were more likely to buy a gun for self-protection. This is an example of a case where correlation may not imply causation. There has been a good deal of research on this question. See, for example, a Harvard School of Public Health 2011 interview with David Hemenway

Assume a society consists of two economic​ groups: one group is rich and the other group is poor. Suppose that 50% of the population is rich while the other 50% of the population is poor. Consider two scenarios. Scenario​ A: The rich have ​$60,000 ​each, while the poor have ​$2,000 each. Scenario​ B: The rich have ​$7,500 ​each, while the poor have ​$750 each. If you only care about average income and not about​ equity, you would prefer ▼ Scenario A Scenario B ​, which has an average income of ​$_______.

Since 5050 percent of the population is rich and 5050 percent of the population is​ poor, we calculate the average income​ as: left parenthesis 50 % times Rich income right parenthesis plus left parenthesis 50 % times Poor income right parenthesis(50%×Rich income)+(50%×Poor income) Scenario A has an average income of ​$31 comma 00031,000​, and Scenario B has an average income of ​$4 comma 1254,125. Since Scenario Upper AScenario A has a higher average​ income, it is the preferred option if we are only considering averages.

Consider the following data that shows the quantity of coffee produced in Brazil from 2004-2012. Year Production (in tons) 2004 2,465,710 2005 2,140,169 2006 2,573,368 2007 2,249,011 2008 2,796,927 2009 2,440,056 2010 2,907,265 2011 2,700,440 2012 3,037,534 a. Plot the data in a time series graph. b. What is the mean quantity of coffee that Brazil produced from 2009 to 2011? c. In percentage terms, how much has the 2012 crop increased over the 2009-2011 mean?

a. A time-series graph can be used to represent the quantity of coffee produced from 2004 to 2012. b. The average quantity of coffee that Brazil produced during the 2009-11 period is 2,682,587 tons. This is the sum of the total quantity produced divided by the number of years. c. The coffee crop in 2012 is 14.6% larger than the average coffee crop in 2009-2011. The increase in production is 3,073,534 - 2,682,587 = 390,945. In percentage terms, the change is 390,947 / 2,682,587 = 14.6%.

A1. How would you represent the following graphically? a. Income inequality in the U.S. has increased over the past 10 years. b. All the workers in the manufacturing sector in a particular country fit into one (and only one) of the following categories: 31.5 percent are high school dropouts, 63.5 percent have a high school diploma, and the rest have vocational training certificates. c. The median income of a household in Alabama was $43,464 in 2012, and the median income of a household in Connecticut was $64,247 in 2012.

a. Since the graph needs to show how income inequality increases over a period of time, a time-series graph needs to be used here. b. A pie chart is a circular chart split into segments to show the percentages of parts to the whole. Since the given data is in percentages, a pie-chart can be used to represent each category of workers. c. A bar chart would be a good way to compare income in Alabama and Connecticut. The height of each bar would represent the income in each one of the states.

This chapter stressed the importance of using appropriate samples for empirical studies. Consider the following two problems in that light. a. You are given a class assignment to find out if people's political leanings affect the newspaper or magazine that they read. You survey two students taking a political science class and five people at a coffee shop. Almost all the people you have spoken to tell you that their political affiliations do not affect what they read. Based on the results of your study, you conclude that there is no relationship between political inclinations and the choice of a newspaper. Is this a valid conclusion? Why or why not? b. Your uncle tells you that the newspaper or magazine that people buy will depend on their age. He says that he believes this because, at home, his wife and his teenage kids read different papers. Do you think his conclusion is justified?

a. The conclusion is not likely to be valid as the sample used in the study is too small. Convincing data analysis will depend on a much larger sample of people. The subjects of the study should also be randomly chosen to minimize the possibility of the results being biased. b. This is an example of argument by anecdote. Using a small sample of people to judge a statistical relationship is likely to lead to flawed conclusions. The fact that your uncle's wife and kids do not base their reading on their political affiliations does not mean that others do not. In order to arrive at a conclusion, you need to survey more people and also make sure that they are chosen randomly.

A3. Suppose the following table shows the relationship between revenue that the Girl Scouts earn and the number of cookie boxes that they sell. Number of cookie boxes Revenue ($) 50 200 150 600 250 1,000 350 1,400 450 1,800 550 2,200 a. Present the data in a scatter plot. b. Do the two variables have a positive relationship or do they have a negative relationship? Explain. c. What is the slope of the line that you get in the scatter plot? What does the slope imply about the price of a box of Girl Scout cookies?

a. The following line chart shows the relationship between the Girl Scouts' revenue and the number of cookie boxes that they sell: b. Since the values of both variables increase together in the same direction, they have a positive relationship. This means that as more cookie boxes are sold, the revenue earned increases. c. The slope is constant in this problem and so we can choose any two points to calculate the slope. Suppose we use the first and last data points. The slope is calculated as . The slope implies that one extra box of cookies sold is associated with $4 more in revenue.

9. A simple economic model predicts that a fall in the price of bus tickets means that more people will take the bus. However, you observe that some people still do not take the bus even after the price of a ticket fell. a. Is the model incorrect? b. How would you test this model?

a. The model is not incorrect. Models are only approximations of real-life behavior. Even very good models make predictions that are often correct. So, on average, more people will take the bus. The model is also likely to have made some assumptions, such as no change in costs of other types of transport, or that people have no specific preferences and cost is the only determinant of the mode of transport used. In reality, some of these assumptions may be violated which could explain why a fall in the price of bus tickets does not induce everyone to take the bus. That does not imply that the model's conclusion is incorrect. In situations where the assumptions it makes are satisfied, its prediction will often be correct. b. The hypothesis here states that as bus prices fall, the number of passengers who take the bus will increase. A natural experiment can be used to test this model. You can use data on price changes and changes in revenues earned from tickets to see whether the model is accurate.

As the text explains, it can sometimes be very difficult to sort out the direction of causality. a. Why might you think more police officers would lead to lower crime rates? Why might you think that higher crime rates would lead to more police officers? b. In 2012, the New England Journal of Medicine published research that showed a strong correlation between the consumption of chocolate in a country and the number of Nobel Prize winners in that country. Do you think countries that want to encourage their citizens to win Nobel Prizes should increase their consumption of chocolate?

a. There is a great deal of evidence that increasing the number of police officers in a neighborhood can drive down crime. The police, for example, will deter criminals who realize the chances they will be caught have gone up and the police may be able to head off conflicts between gangs. Therefore more police could lead to less crime. Cities strategically assign more police to high crime areas (since by definition, those are the areas where crimes are more likely to occur). Therefore, more crime can lead to more police. b. Correlation does not necessarily imply causation. A strong positive correlation between chocolate consumption and Nobel Prize winners does not, by itself, suggest causation. It is possible that this is a chance correlation. It may also be case that certain variables that could explain this relationship have been omitted from the study.

In this​ question, we will use what you learned in the second part of the chapter to compare the performance of an economy in two different time​ periods, as its physical capital stock and efficiency units of labor change. Suppose that from period 1 to period​ 2, the unemployment rate in the economy increases. Everything else remains unchanged. The total efficiency units of labor will ▼ increase decrease because ▼ less workers are employed more workers are employed

decrease; less workers are employed reason: The total efficiency units of​ labor, denoted by H​, is the product of the total number of workers in the​ economy, L​, and the average efficiency or human capital of​ workers, h. The total efficiency units of labor in period 1 is H1​ = L1​ × h1 and in period 2 is H2 ​= L2​ × h2. Here L refers to the total number of employed workers in the economy​ (the workforce). If the level of unemployment​ increases, L is likely to fall. This will reduce the total efficiency units of​ labor, which means that ​(H1​ = L1​ × h1​) ​> ​(H2 ​= L2​ × h2​).

at minium wage, how is the quantity of labor supplied in relation to the quantity demanded

many early theories of business cycles assumed that economic fluctuations had a pendulum-like structure with systematic swings in economic growth- which is far from the truth

correlation

means that there is a mutual relationship between 2 things

national income accounts

measure the level of aggregate economic activity in a country (the entire economy)

the Great Depression featured the limited predictability aspect how?

most people thought the strength of the economy would go far beyond 1929, and the the stock market crashed...it was so sudden

Oregon expanded its Medicaid coverage in 2008. Roughly​ 90,000 people applied but the state had funds to cover only an additional​ 30,000 people. The state used a lottery to determine who would receive this free health care insurance from Medicaid. How could you use the Oregon experience to estimate the impact of increased access to health care on health​ outcomes? The Oregon experience is a ▼ natural experiment statistical experiment laboratory experiment . One might analyze the data as​ follows: gather and analyze the data on the health care outcomes for the two groups to determine if ▼ free health care results in better health outcomes free health care results in a larger public debt more doctor vists result in more emergency room visits .

In general people with more education earn higher salaries. Economists have offered two explanations of this relationship. The human capital argument says that high schools and colleges teach people valuable​ skills, and employers are willing to pay higher salaries to attract people with those skills. The signaling argument says that college graduates earn more because a college degree is a signal to employers that a job applicant is​ diligent, intelligent, and persevering. The ▼ correlation argument human capital argument signaling argument causation argument implies that a college student who drops out of school one month before graduation should earn much less than a student who graduates.

he ​Evidence-Based Economics in the chapter identifies three key factors that caused the recession of 2007dash-2009. How would​ Keynes's concept of animal spirits explain the creation of a housing​ bubble? A. Home builders reduced their level of construction and​ investment, which led to higher prices and profits due to decreased​ supply, and as inventory​ declined, prices continued to climb. B. People believed that a house was a worthwhile​ investment, which led to an increased demand for housing and thus pushed prices up. This confirmed to people that housing was a worthwhile​ investment, which led to more​ demand, resulting in an upward spiral driven by optimism. C. With an expanding​ economy, real wages were driven​ up, leading to higher demand for​ housing, which expanded the economy further and drove up wages​ again, resulting in an upward spiral driven by optimism. D. The increase in mortgage defaults led to reduced lending by​ banks, which in turn reduced demand for​ housing, leading to more defaults and higher prices for those who could buy as banks attempted to recoup losses.

B. People believed that a house was a worthwhile​ investment, which led to an increased demand for housing and thus pushed prices up. This confirmed to people that housing was a worthwhile​ investment, which led to more​ demand, resulting in an upward spiral driven by optimism.

Assuming flexible​ wages, in which case would the change in total employment be greater during a​ recession: Scenario​ 1: If workers do not increase their quantity of labor supplied very much in response to an increase in the wage. Scenario​ 2: Workers substantially increase their quantity of labor supplied in response to an increase in the wage. A. Scenario​ 1, because the labor supply curve in this case will be steeper. B. Scenario​ 2, because the labor supply curve in this case will be flatter. C. Scenario​ 2, because the labor supply curve in this case will be steeper. D. Scenario​ 1, because the labor supply curve in this case will be flatter.

B. Scenario​ 2, because the labor supply curve in this case will be flatter.

Some economists stress the role of monetary policy in the period leading up to the recession of 2007dash-2009. Between 2001 and​ 2003, the Federal Reserve lowered the target federal funds rate from​ 6.5% to​ 1%, and kept it there through much of 2004. This resulted in a substantial decline in real interest rates throughout the​ economy, including mortgage rates. Based on the​ chapter's discussion of monetary and financial​ factors, how could the Federal​ Reserve's policies have contributed to the economic​ "bubble" of the​ pre-recession years of 2000dash-​2006? A. The rapid decrease in the federal funds rate led to increased consumption because of the low return on​ savings, which increased demand in the economy above the sustainable level. B. The low federal funds rate also lowered the rate at which businesses could​ borrow, driving an increase in demand for​ investment, which in turn drove up real wages. C. The low federal funds rate also lowered mortgage​ rates, driving an increase in demand for​ housing, which in turn drove up real estate prices. D. The Federal​ Reserve's policies increased the multipliers in the​ economy, increasing the impact of the boom and therefore the subsequent crash.

C. The low federal funds rate also lowered mortgage​ rates, driving an increase in demand for​ housing, which in turn drove up real estate prices.

Firms, households, and governments use the credit market for borrowing. The credit demand curve shows the relationship between the quantity of credit demanded and the real interest rate. The credit demand curve slopes downward because​ ____________. A. government borrowing increases when budget deficits​ increase, and vice versa. B. a​ lender's ability to make loans falls as the real interest rate rises. C. a higherhigher real interest rate reducesreduces a borrowing​ firm's profit and hence its willingness to borrow.
