Second Midterm - II

Binary Choice:

1) Suppose the independent nation of Sealand increased its imports from the United States this year, and all other spending remains unchanged from the prior year. Given this information, Joseph reasons (by means of the expenditure approach) that Sealand's GDP has increased this year because of the additional spending on imports.

Is Joseph's reasoning correct?

b) No, Sealand's GDP has not increased this year.

2) In October 2009, the official unemployment rate (U3) in the US peaked at 10%. If the Bureau of Labor Statistics (BLS) counted discouraged workers as unemployed, then the unemployment rate in October 2009 would have been:

b) 10%, because discouraged workers are already counted in U3.

 3) The Simpsons borrowed money, that is took out a mortgage, in order to buy a house. At the time of the house purchase, the nominal interest rate on the mortgage was 10%, with an expected inflation rate of 7%. If the actual inflation rate is 5% over the period of time the Simpsons are repaying their house loan, how will this affect the Simpsons?

a) The lower than expected inflation rate makes this mortgage more expensive in real terms for the Simpsons.

b) The lower than expected inflation rate makes this mortgage less expensive in real terms for the Simpsons.

4) Kevin deposits $1000 in the bank and receives $1050 at the end of the year. If the inflation rate was 10% during this period, then what is the approximate average real return on Kevin's savings?

5) Suppose we know that the government computes the CPI using a basket of only apples and onions, but we do not know exactly how many apples and onions are in this fixed basket. Further, suppose that in 2014, the CPI was 100, and the price per apple was $1 and the price per onion was $1.

In 2015, the price of apples increased to $2 per apple, while the price of onions remained fixed at $1 per onion. The CPI for 2015 increased to 110. Given this information, are there more apples or onions in the CPI basket?

 6) A large fraction of the labor force of Buggyland produces buggy whips. At the same time, Autoland invents the car and exports great numbers of cars to Buggyland. These exports put buggy whip manufacturers out of business in Buggyland and the buggy whip industry becomes obsolete.

Given this information and holding everything else constant, in Buggyland the unemployment rate increases while the natural rate of unemployment remains the same.

a) True

b) False

7) If output and employment in an economy are above the full-employment level, then this implies that:

a) The natural unemployment rate has fallen.

b) This economy is producing in the short-run above the long-run trend line of real GDP.

8) Suppose this year, Neverland experiences a major economic downturn. Because of this economic downturn, 20% of the labor force was laid off while the capital stock was unaffected. Assume that Neverland's aggregate production function has the usual properties of diminishing marginal returns and can be expressed as Y = αK1/2 L1/2. Given this information, and holding all else fixed:

a) Neverland's total output falls by more than 20%.

b) Neverland's total output falls by less than 20%.

9) Suppose Canada has recently seen an increase in its employment due to immigration. At the same time, Canada lost some of its productive capital due to a major fire (no people were harmed in this fire). Given this information and holding everything else constant, what can we say about the marginal product of capital and total output (real GDP) in Canada after the immigration and fire? (Assume that Canada's aggregate production function has the usual properties of diminishing marginal returns and can be expressed as Y = αK1/2L1/2.)

a) Total output falls and the marginal product of capital is indeterminate.

b) Total output is indeterminate, and the marginal product of capital increases.

10) Financial analysts predict that the country of Guyana will have very high economic growth this year. This prediction improves consumers' confidence in the economy, making them more inclined towards consumption and less inclined towards savings.

a) The interest rate in Guyana will rise.

b) The interest rate in Guyana will fall.

In May 2010, there were 10,000,000 people aged 16 or older in the civilian noninstitutionalized labor force living in Gruyovia. The dictator of Gruyovia insists that the economy is doing well because the labor force participation rate is at 80%. However, his opponents argue that 1/4 of those people are working only part-time, and another 1/2 of these people are still looking for jobs (assume both the dictator's and his opponents' data are correct).

b) 50%

c) 75%

d) We cannot calculate the unemployment rate from the information given.

22) After hearing the opponents' arguments, 1,000,000 people who were not employed and were not actively searching for work leave the country.

Assume these changes occur between May and the end of June 2010. Assume there are no other changes to the labor market in Gruyovia.

When the interest rate rises to 10%, the quantity of loans supplied increases to $20,000 while the quantity of loans demanded drops to $10,000.
