II. Problems: Insert your answer to each question in the box provided. Feel free to use the margins for scratch workonly the answers in the boxes will be graded. Work carefullypartial credit is not normally given for questions in this section. (1) [Labor force: 6 pts] The Bureau of Labor Statistics reported that in September 2004, 139.6 million people were employed, 7.5 million people were unemployed, and 76.8 million working-age people were not in the labor force. a. Compute the unemployment rate (to the nearest tenth of a percentage point).
b. Compute the labor force participation rate (to the nearest tenth of a percentage point).
c. Compute the employment-to-population ratio (to the nearest tenth of a percentage point).
(2) [Interest rate: 4 pts] Suppose the interest rate is 3%. a. The opportunity cost of $1 of consumption today is how many dollars of consumption next year?
b. The opportunity cost of $1 of consumption next year is how many dollars of consumption today?
(3) [Interest rate and GDP shares: 10 pts] Suppose the following three equations relate the shares of consumption (C), investment (I), and net exports (X) in total GDP (Y) to the real interest rate (r) in the long run. In these equations, the GDP shares and the interest rate are expressed as percents.
Suppose further that the share of government purchases (G/Y) is fixed at 20 %. Compute the following. [Hint: Check your answer to be sure that the four GDP spending shares sum to 100%.] a. Interest rate (r)
d. Net exports' share of GDP (X/Y):
b. Consumption's share of GDP (C/Y):
e. Savings as a share of GDP (S/Y):
c. Investment's share of GDP (I/Y):
(4) [Interest rate and GDP shares: 10 pts] Suppose the government provides tax incentives for businesses to spend money on computer hardware and software. Use the spending allocation model to answer the following questions. [Hint: Use the graphs below for scratch work.] a. Does the long-run real interest rate increase, decrease , or remain constant? b. Does the share of consumption spending (C/Y) increase, decrease , or remain constant? c. Does the share of investment spending (I/Y) increase, decrease , or remain constant? d. Does the share of net exports (X/Y) increase, decrease , or remain constant? e. Does the long-run growth rate of real GDP increase, decrease , or remain constant? (5) [Malthusian model: 12 pts] The diagram below shows a Malthusian model of economic growth.
a. According to this Malthusian model, how much output is required to sustain each worker? In other words, what is the subsistence level of output per worker? $ b. If the labor force were 12 million, would the population tend to increase, decrease, or remain constant? c. If the labor force were 4 million, would the population tend to increase, decrease, or remain constant? d. What is the equilibrium level of annual wages (output per worker) according to this model? $ e. What is the equilibrium size of the labor force according to this model? (^) million f. Suppose the production function shifts down due to an environmental disaster. What will be the new equilibrium level of annual wages, according to this model? $

Full credit requires correct economic reasoning, legible writing, good grammar including complete sentences, and accurate spelling. [4 pts] (1) Consider the following statement. "The world is getting more and more crowded. Soon we will run out of natural resources and economic growth will stop." Do you agree or disagree? Why or why not? Cite the historical record.
