- its long run growth rate
- its short run GDP
- its long run standard of living
- its investment behavior
- its interest rates
Explain your answer:

- Unlike the Asian tiger economies such a Singapore, rapid economic growth has been largely driven by capital accumulation
- Like the Asian tiger economies such a Singapore, rapid economic growth has been largely driven by capital accumulation
- Unlike the Asian tiger economies such a Singapore, rapid economic growth has been largely driven by rapid population growth
- Like the Asian tiger economies such a Singapore, rapid economic growth has been largely driven by rapid population growth
- Like the Asian tiger economies such a Singapore, low investment rates have held back Chinese growth
Explain your answer:

- is conducted for profit; entrepreneurship is not
- involves risk taking; entrepreneurship does not
- is a zero-sum game; entrepreneurship is not
- involves innovations; entrepreneurship does not
- is illegal; entrepreneurship is not
Explain your answer:
- Cultural and social forces, such as religious prohibitions on certain activities or ethical norms regarding effort;
- have no effect on economic output, and so are deliberately excluded from growth accounting
- are not captured in the production functions used for growth accounting
- are assumed to influence total factor productivity
- are measured as part of labor input
- are treated as ‘social capital’ in the production function
Explain your answer:
- Which of the following would not give workers some degree of monopoly power?
- learning by doing
- labor unions
- highly specialized human capital
- high rates of short-term unemployment
- high costs of job turnover and training incurred by employers
Explain your answer:
- Unemployment insurance benefits increase productivity most by
- shortening the duration of unemployment
- providing replacement rates that are lower than real wages
- shifting government funds away from less productive ventures
- helping to improve the match-up between jobs and workers
- weakening monopoly power
Explain your answer:
- Which of the following is not an example of intra-industry trade?
- England exports beef to Ireland, and imports Irish potatoes.
- the Dutch export elm trees and import lumber products.
- Canadians touring the US side of Niagara Falls stay in US motels while Americans touring the Canadian side stay in Canadian hotels.

Explain your answer:
- Country A has a large pool of skilled workers earning $50 per hour and a small pool of unskilled workers earning $18 per hour. Country B has a small pool of skilled workers earning $60 per hour and a large pool of unskilled workers earning $8 per hour. Trade theory predicts that if A and B engage in international trade with each other,
- real wages paid to skilled workers will fall in A
- unskilled wages will become more unequal between A and B
- real incomes will become more equal within B
- the wages of unskilled workers in B will fall
- wages to all workers in both countries will rise
Explain your answer:
- Who among the following is likely to have the highest marginal propensity to consume out of current income?
- a rational consumer who intends to behave strictly according to the permanent income hypothesis
- a risk averse consumer facing a high degree of uncertainty
- a low-income consumer facing borrowing constraints
- a working age consumer looking forward to retirement
- a wealthy parent who is currently accumulating funds to bequeath to his heirs
Explain your answer:
Consider an individual who enters adulthood and the labor force at age 18, expects to work 5 years at a real income of $10,000 per year, anticipates earning a real income of $40,000 per year from age 23 to 63, expects to retire with a $10,000 annual pension, and live until age 78. Suppose the interest rate is zero, and the individual seeks perfectly smooth consumption across his adult lifetime.
- In the absence of borrowing constraints, then beginning at age 18, the individual should consume
- all of his income as he receives it each year
- $10,000 every year
- $20,000 every year
- $30,000 every year
- $25,000 every year
Explain your answer:
Consider the following production function for a delivery service.
Number of trucks: 0 1 2 3 4 5
Number of deliveries: 0 100 170 230 280 300
Each delivery generates $200 in gross revenue, and the tax rate is 10 percent on profits. Each truck costs $11,000.
- The optimal number of trucks is
- 1
- 2
- 3
- 4
- 5
Explain your answer:
- Which of the following correctly describes a theory of wage behavior during the business cycle?
- Real Business Cycle theory holds that workers are relatively unresponsive to wage changes
- Classical theory holds that nominal wages are inflexible
- Keynesian theory holds that real wages may rise during recessions, preventing labor markets from clearing
- Rational expectations theory holds that workers continue to anticipate wage increases during recessions
- Marxist theory holds that unions cause recessions by keeping wages too high
Explain your answer:
- A sudden, unexpected increase in the economy’s prevailing wage level due to a general strike threat would
- shift the aggregate demand curve out and push equilibrium prices down
- shift the aggregate demand curve in and push equilibrium output down
- shift the short run aggregate supply curve in and push equilibrium prices up
- shift the Phillips Curve in and increase the natural rate of unemployment
- shift the long run aggregate supply curve out and push equilibrium prices down
Explain your answer:
- When depositors transfer funds from savings accounts to checking accounts,
- M2 falls and M1 rises, while M3 remains constant
- b) M1 rises while M2 and M3 remain constant
- c) Both M1 and M2 increase, while M3 falls
- d) M3 falls while M1 and M2 remain constant
- e) M1 falls, M3 rises, and M2 remains constant
Explain your answer:
- According to the quantity theory of money,
- the quantity of money determines the long run equilibrium price level
- the amount of money in the economy determines the long run quantity of output
- money affects the aggregate supply curve, while the aggregate demand curve determines real output
- the money supply only affects the economy in the long run, not in the short run
- the full-capacity level of output determines the supply of money needed in the economy
Explain your answer:
- Consider the following (hypothetical) cash economy with no banks. The money supply consists entirely of $1000 in currency. Output is currently at potential. The government is currently faced with a $100 budget deficit and chooses not to raise taxes, but instead prints $100 more currency with which to balance its budget. The long run result is likely to be
- an interest rate of 10%
- an inflation rate of 10%
- a 10% increase in the velocity of money
- a 10% growth rate of real GDP
- a 10% increase in the national debt
Explain your answer:
- Which of the following is the most appropriate model for a central bank conducting discretionary stabilization policy?
- observe what the unemployment rate has been in recent periods, estimate the difference from the natural rate, and adjust the money supply accordingly
- observe the current level of GDP, estimate the output gap between actual and potential GDP, and adjust bank reserve requirements accordingly
- observe the past and current trade-weighted exchange rate, estimate the difference from purchasing power parity, and adjust income taxes accordingly
- predict the future inflation rate based on current and recent trends in economic variables, estimate the difference from the target rate, and tighten or loosen lending accordingly
- disregard current trends and simply keep the money supply growing at a rate equal to the long run growth rate of GDP
Explain your answer:
- Targeting interest rates and targeting the money supply are equivalent if
- money demand is stable
- banks hold no excess reserves
- exchange rates are fixed
- central banks practice inflation targeting
- consumers exhibit rational expectations

- Economic impact of having strong and supportive social security in old age on saving behavior of people within various countries?
- Study of business cycles is one of the key topics in study of macroeconomics. Give short and concise answers to the following questions:
- In early 1980s increase in price of oil forced a number of governments to increase interest rate. Why have they done so and do you agree with such decision?
- Real business cycle theory implies that negative total factor productivity shocks cause recession. What do you think such shocks might be?
- Explain if the central bank is engaged in expansionary or contractionary monetary policy under each of the following circumstances and explain the likely impact on real GDP, rate of unemployment, and price level:
