Document Summary

(126-120)/120 x 100 = 5% but then divide by two because was over the course of two years. Real gdp measures the quantity of total output produced by the nations economy over the period of one year. If the output gap measures the output loss due to the failure to achieve full employment it can concluded that the larger the output gap, the greater the unemployment rate.

Cyclical unemployment eg. worker laid off b/c firm had to reduce production due to decreased demand. Cpi change from 120 in year 2012 to 126 in 2014. In an economy where existing capital is being used to the highest degree, shortages in labour and good markets are developing, and costs are rising this is a peak. Real interest rate must be positive if the nominal rate of interest is > rate of inflation.

Consider a hypothetical economy in which the labour force consists of 100 people. Of those, 85 people are employed full time and 15 people are unemployed. The government of this economy follows the same conventions as the BLS in computing its employment figures. The unemployment rate is simply the number of unemployed people divided by the number of people in the labour force. Initially, then, the unemployment rate is (15/100) x 100% = 15.0%

Suppose a reduction in foreign demand for this economy's products causes an economic recession-a prolonged period of declining output. The following table offers two different possible scenarios resulting from the recession. Calculate the unemployment rate associated with each scenario

2. Firms reduce work hours by 25%. The number of underemployed workers rises as firms respond to the reduction in the demand for their products by reducing the hours of each employed person from 40 to 30 hours per week.

3. Firms reduce employment by 25%. The number of unemployed workers rises as firms respond to the reduction in the demand for their products by laying off 21 previously employed workers.

4. The unemployment rate in scenario 3 ____ the true extent of underemployment in the economy because the BLS counts part-time workers as employed.

A. Overstates

B. Understates

5. Consider a hypothetical economy in which potential output is $400 billion and the natural rate of unemployment is 6%. The current employment rate is 7.4%. Since the unemployment rate is greater than the natural rate of unemployment, the economy's actual GDP will be ____ potential GDP.

A. Less than

B. Greater than

C. Equal to

6. The burden of an increase in the economy-wide unemployment rate can differ widely across regions and different groups of people. For example, in the United States, the jobless rate among minorities has tended to be ___ than the jobless rate among whites.

A. Lower

B. Higher

1) Assume the following data for a country: total population, 500; population under 16 years of age or institutionalized, 120; not in labor force, 150; unemployed, 23; part-time workers looking for full-time jobs, 10. What is the size of the labor force? What is the unemployment rate?

2) If the CPI was 110 last year and is 121 this year, what is this yearâs rate of inflation? In contrast, suppose that the CPI was 110 last year and 108 this year. What is this yearâs rate of inflation? What term do economics use to describe this second outcome?

3) Use the hypothetical economy data in the table below to answer the following questions.

Amount of Real GDP Demand, in Billions	Price Level (Price Index)	Amount of Real GDP Supplied, in Billions
$180	300	$500
260	250	400
300	200	300
420	150	200
560	100	100

b) At what price level will aggregate supply FALL BELOW [equal] aggregate demand? At what price level will demand fall below aggregate supply? If given a price level of 250, will aggregate demand exceed supply?

3) Determine whether each of the following would be considered frictional, structural, seasonal, or cyclical unemployment:

a. A UPS employee who was hired for the Christmas season is laid off after Christmas

c. A worker in a DVD rental store becomes unemployed as video-on-demand cable service becomes more popular.

d. A new college graduate is looking for employment.

5) When the economy is at full employment, is the unemployment rate at zero percent? Why or why not? How would a more generous unemployment insurance system affect the full employment figure?

1) How do we measure labor productivity? How do changes in labor productivity affect the U.S. standard of living?

5) Supposed that two nation start out in 2013 with identical levels of output per work hour â say, $100 per hour. In the first nation, labor productivity grows by 1 percent per year. In the second, it grows by 2 percent per year. Use a calculate or spreadsheet to determine how much output per hour each nation will be producing 20 years later, assuming that labor productivity growth rates do not change. The, determine how much each will be producing per hour 100 years later. What do your results tell you about the effect of small differences in productivity growth rates?

7) What are some examples, other than those given in the chapter of technological change that has caused unemployment? And what are some examples of new technologies that have created jobs? How do you think you might measure the net impact of technological change on overall employment and GDP in the United States?
