propensity to consume falls as income rises?

per month and a job-finding rate of 0.10 per month, and the labor force was 100
million, how many individuals would lose their jobs each month?
Fiscal policy is a tool the government uses to steer the economy of a country. What are
the advantages of active fiscal policy over passive fiscal policy?
A change in money supply shifts the LM curve downward. Explain why.
One of the key distinctions made in the analysis of the Solow growth model is between
changes in levels and changes in growth rates. How does an increase in the rate of
population growth change the steady-state levels and growth rates of output and output
per worker in the Solow model with no technological change?

means that the money demand function of the population already takes into account

and unemployment? Illustrate your answer using a Phillips curve diagram.

convergence occur?

In the 2008 global financial crisis, many investors considered the U.S. economy a safe
place to move their assets. What is the predicted impact of this inflow of financial
capital to the United States, which is a large open economy, on the U.S. interest rate and

Use the IS"LM model to illustrate graphically the impact of the Pigou effect on the
equilibrium level of income and interest rate during the Great Depression, when prices
were falling.
Use the neoclassical model of business fixed investment to illustrate graphically how a
hurricane that destroys a large amount of capital (holding other factors constant) would
change the rental price of capital. If other factors remained unchanged, how would this
change the quantity of investment spending in the economy?

During periods of economic downturn, there is frequently pressure to protect domestic
production from foreign competition in the belief that protectionist policies will save
