c.Real GDP falls because with fewer workers on the job, firms produce less. Thisaccurately reflects a fall in economic well-being.d.Real GDP falls because the firms that lay off workers produce less. This decreaseseconomic well-being because workers’ incomes fall (the income side), and there are fewer goods for people to buy (the expenditure side).e.Real GDP is likely to fall, as firms shift toward production methods that producefewer goods but emit less pollution. Economic well-being, however, may rise. The economy now produces less measured output but more clean air; clean air is not traded in markets and, thus, does not show up in measured GDP, but is neverthe-less a good that people value.f.Real GDP rises because the high-school students go from an activity in which theyare not producing market goods and services to one in which they are. Economic well-being, however, may decrease. I n ideal national accounts, attending school would show up as investment because it presumably increases the future produc-tivity of the worker. Actual national accounts do not measure this type of invest-ment. Note also that future GDP may be lower than it would be if the students stayed in school, since the future work force will be less educated.g.Measured real GDP falls because fathers spend less time producing market goodsand services. The actual production of goods and services need not have fallen, however. Measured production (what the fathers are paid to do) falls, but unmea-sured production of child-rearing services rises.9.As Senator Robert Kennedy pointed out, GDP is an imperfect measure of economic per-formance or well-being. In addition to the left-out items that Kennedy cited, GDP also ignores the imputed rent on durable goods such as cars, refrigerators, and lawnmowers;many services and products produced as part of household activity, such as cooking and cleaning; and the value of goods produced and sold in illegal activities, such as the drug trade. These imperfections in the measurement of GDP do not necessarily reduce its usefulness. As long as these measurement problems stay constant over time, then GDP is useful in comparing economic activity from year to year. Moreover, a large GDP allows us to afford better medical care for our children, newer books for their education, and more toys for their play. Finally, countries with higher levels of GDP tend to have higher levels of life expectancy, better access to clean water and sanitation, and higher levels of education. GDP is therefore a useful measure for comparing the level of growth and development across countries.。

W hat is the consumer price index (CPI)? What are the three major items included in the CPI?RESPONSE:ANSWER: The CPI is a measure of the overall cost of the goods and services bought by a typical consumer. The three major items included in the CPI are shelter, transportation andfood.POINTS: -- / 12. H ow is the CPI computed?RESPONSE:ANSWER: First the basket of goods and services must be determined and also the relative importance of the various items to be included in the basket. Then the prices of thevarious items in the basket are determined. The cost of the basket is then determinedusing the data on prices and quantity. The base year is chosen, and the index for thebase year is computed using the quantities in the basket and the base year prices.The index is calculated by taking the price of the basket in the each year and dividingthis by the price of the basket in the base year. This ratio is then multiplied by 100. POINTS: -- / 13. D ifferentiate between the nominal rate of interest and the real rate of interest.RESPONSE:ANSWER: The nominal interest rate is the interest rate as usually reported without a correction for the effects of inflation. The real interest rate is the interest rate corrected for theeffects of inflation. The real interest rate = nominal interest rate minus the inflationrate.POINTS: -- / 14. W hat is meant by the inflation rate? If the CPI in 1996 was 107.6 and in 1995 was 105.9, calculatethe inflation rate for 1996.RESPONSE:ANSWER: The inflation rate is the percentage change in the price index from the preceding period. The inflation rate for 1996 would be:POINTS: -- / 15. W hat are the problems associated with using the consumer price index to measure the cost ofliving?RESPONSE:ANSWER: The problems are: (1) Prices do not change proportionately. Consumers respond by buying less of the goods whose prices have risen by large amounts and by buyingmore of the goods whose price have risen by less, or even fallen. The index iscomputed using a fixed basket of items, so theses changes in quantity would not bereflected in the basket. This is referred to as the substitution bias. (2) The CPI isdeveloped using a fixed basket of goods and services, when new products areintroduced during the time period that a particular fixed basket is being used, thesenew products will not be included in calculation of the index. (3) The CPI does notmeasure quality changes. If the quality of a good deteriorates from one year to thenext, the value of the dollar falls, even if the price of the good stays the same.Likewise, if the quality of the good increases from one year to the next, the value of adollar also rises. Statistics Canada will try to adjust the price of the good to account forthe quality change, but it is very difficult to measure quality.POINTS: -- / 1CHAPTER 25: PRODUCTION AND GROWTHTrue/FalseIndicate whether the statement is true or false.1.

W. Phillips.D) The curve is downward sloping.Answer: ADiff: 12.2 Essay Questions1) Explain the three ways GDP can be measured.Answer: GDP can be measured three ways. First, GDP represents the market value of the final goods and services produced in the economy during a given period. This would be obtained by adding C, I, G, and NX. Second, GDP is the sum of the value added by firms. The value added for a firm equals the value of the production (at that stage of the production process) minus the value of the intermediate goods (excluding labor services). The final value of aggregate output can be calculated by either summing the value of all final goods and services OR by summing the value added of all goods and services at each stage of production. And finally, GDP is also the sum of all incomes earned in a given period.2) First, define nominal GDP and real GDP. Second, is it possible for nominal GDP in a year to be less than real GDP in the same year? Explain.Answer: Nominal GDP represents the value of goods and services produced using current prices. Real GDP measures the value of the same goods and services using some base year prices. It is possible for nominal GDP to be less than real GDP in a given year. Given the definitions of the two variables, this will occur if prices in that year are simply less than prices in the base year. If, for example, the base year is 2002, it will generally be the case that nominal GDP will be less than real GDP for those years prior to 2002 given that prices have generally risen in all years. 3) Explain whether it is possible for nominal GDP to increase and real GDP to decrease in the same period.Answer: Nominal GDP can rise because either the price level is rising or the real quantity of goods and services produced has increased. Nominal GDP can increase while real GDP falls if the increase in the aggregate price level is larger (in a proportionate sense) than the drop in real economic activity.4) Explain the difference between the unemployment rate and the participation rate.Answer: The unemployment rate is the percentage of the labor force (those employed and unemployed) that is unemployed. The participation rate is the percentage of the working age population that is in the labor force.5) Explain how the existence of discouraged workers alters the extent to which the official unemployment provides an accurate measure of the use of labor resources.Answer: Discouraged workers are those individuals who have decided to stop searching for employment because they have become "discouraged" about employment opportunities. At some point, these individuals will no longer be considered as part of the labor force. The existence of discouraged workers willcause the official unemployment rate to provide an under-estimate of the underutilization of labor.6) Briefly explain why the reported official unemployment rate in Spain in 1994 may have provided an over-estimate of unemployment in Spain.Answer: The relatively high unemployment rate in Spain is partly the result of a relatively large underground economy. The underground economy is that part of the economy not measured in official statistics. After taking into account those individuals who are "employed" in the underground economy, the unemployment rate in Spain would have been lower (but still relatively high).7) What are the social and economic implications of unemployment? Explain.Answer: Economic implications: signal of economic activity and measure of the utilization of labor. Social implications: the emotional and psychological suffering that occurs as a result of being unemployed.8) Explain what factors cause changes in output in: (1) the short run; (2) medium run; and (3) long run.Answer: In the short run, demand factors primarily cause changes in output. In the medium run, factors such as the technology, amount of capital, and the skill and size of the labor force (supply factors) affect output. And in the long run, the education system, saving rate, and role of government affect economic activity.9) Will the CPI and GDP deflator always move together? Explain.Answer: No they will not. Some of the goods included in the GDP deflator (some investment goods) are not included in theCPI. Some of the goods included in the CPI (foreign goods) are not included in the GDP deflator.10) Explain how inflation can lead to distortions.Answer: First, not all prices and wages adjust automatically when inflation occurs. Second, variations in relative prices (which occur when there is not pure inflation) can lead to uncertainty. Inflation can also lead to distortions if the tax system is not adjusted when inflation occurs (e.g. nominal income tax brackets).11) Explain why economists care about inflation.Answer: Inflation will cause relative prices to change. It will also cause changes in the distribution of income. Inflation will lead to other distortions such as tax distortions and uncertainty.12) Explain Okun's Law.Answer: It shows the relationship between GDP growth and unemployment rate. If output growth is high, unemployment will decrease.13) Explain the Phillips curve.Answer: It shows the negative relationship between inflation rate and unemployment rate. After 1970s, it was redefined as the relationship between the change in the rate of inflation and the unemployment rate.14) Explain why the Phillips curve on average is downward sloping.Answer: When unemployment becomes very low, the economy is likely to overheat and this will lead to upward pressure on inflation.15) Explain why economists care about unemployment.Answer: First, they care about unemployment because of its direct effect on the welfare of the unemployed. Unemployment is often associated with financial and psychological suffering.Second, they care about unemployment because it provides a signal that the economy may not be using some of its resources efficiently.16) Can an economy maintain high output growth, low unemployment, and low inflation at the the same time? Explain.Answer: It would be very hard to achieve the three objectives at the same time. High output growth leads to low unemployment, which is likely to put pressure on inflation.。
