Econ midterm 1, ch 1-6
A temporary increase in the wage rate is likely to increase the amount of labor supplied. This is because for temporary wage changes, the income effect is likely to be less than the substitution effect. Which of the following statements best states the effect of a permanent increase in the real wage?
For a permanent wage increase, the income effect is likely to exceed the substitution effect, thus the quantity of labor supplied will fall.
After a boat rescues everyone else from Gilligan's Island, the Professor and Gilligan remain behind, afraid of getting shipwrecked again with the same bunch of people. The Professor grows coconuts and catches fish. Last year he harvested 1500 coconuts and caught 500 fish. He values one fish as worth two coconuts. The Professor gave 300 coconuts to Gilligan in exchange for help in the harvest, and he gave Gilligan 50 fish in exchange for collecting worms for use in fishing. Gilligan consumed all his coconuts and fish.
In terms of fish, the GDP of Gilligan's Island is 1250. In terms of fish, consumption on Gilligan's Island is 1250, and investment is 0. In terms of fish, the income of the Professor is 1050, and the income of Gilligan is 200.
How could changes in the labor market lead to lower overall economic volatility?
Less volatility in employment demand reduces the probability of a worker losing his or her job.
Use the IS-LM model to determine the effects of an influx of working - age immigrants that increases labor supply. Show the effects below on the general equilibrium values of real wage, employment, output, real interest rate, consumption, investment, and price level.
Real wage Decreases Employment Increases Output Increases Price Level Decreases Real Interest Rate Decreases Investment Increases Consumption Increases
The natural rate of unemployment is the rate of unemployment
A. that occurs when both the goods and financial markets are in equilibrium. B. that occurs when the money market is in equilibrium. C. where the markup of prices over costs is equal to its historical value. D. that occurs when the markup of prices over costs is zero. E. none of the abov NONE OF ABOVE
Whenever the expected inflation rate is positive:
A. the real interest rate is greater than the nominal interest rate. B. the real interest rate is negative. C. the real interest rate is positive. D. the nominal interest rate must be equal to the real interest rate. E. none of the above ITS NONE OF ABOVE
Consider an economy with a constant growth rate of nominal money supply and a constant real interest rate r = 0.07. Which of the following statements about the inflation rate of the economy would be valid?
The faster the economy's real output grows, the lower the inflation rate.
Which is NOT a correct statement about the national income accounts?
The income approach to measuring economic activity provides a figure that is equal to the sum of revenues by the producers of output, which in turn is equivalent to that of the product approach.
Okun's law states that the gap between output and full-employment output increases by 2% for each 1% that the unemployment rate increases. Why does a 1% increase in unemployment lead to twice as large an effect on output?
When cyclical unemployment is rising, other factors such as the labor force and worker hours tend to be falling, further reducing output.
All of the following can shift the LM curve down and to the right except
a reduction in money supply.
Which of the following will cause an increase in the amount of money that one wishes to hold?
a reduction in the interest rate increase.
How is the price level related to nominal money demand? How is the level of real income related to money demand? How is the interest rate on other assets (stocks and bonds for example) related to money demand?
They are directly related-the higher the price level, the higher the demand for money. They are directly related They are inversely related
Which of the following best completes the definition of money as used by economists? Money is:
a special set of assets that are widely accepted as payments for goods and services.
Which of the following outcomes of a change in the government budget deficit would increase the current account deficit of a small open economy? If a change in the government budget deficit changes the current account deficit of a small open economy, by how much does the current account deficit change?
an increase in the budget deficit that reduces national saving. By the amount that national saving changes.
If Ricardian equivalence holds, a reduced government budget deficit caused by a lump-sum tax increase in an open economy leads to If Ricardian equivalence does not hold, a reduced government budget deficit caused by a lump-sum tax increase in an open economy leads to
no change in the current account balance. a rise in the current account balance.

What are the effects of each of the following events on output, the real interest rate, and current price level?There is a temporary increase in government purchases. There is a reduction in expected inflation. There is a temporary increase in labor supply. There is an increase in the interest rate paid on money.

the amount of goods we must give up next year in order to consume more goods today.
Two countries are IDENTICAL in every way except that one has a much higher capital-labor ratio than the other. According to the Solow model, which country's total output will grow more quickly? Does your answer depend on whether one country or the other is in a steady state? In general terms, how will your answer be affected if the two countries are allowed to trade with each other?
the country with the lower capital-labor ratio No. The country with the lower capital-labor ratio will always grow faster. both countries will grow even faster
The term saving refers to The term savings refers to
the flow of funds that is not consumed out of income. the stock of funds that represents the accumulated amount of net saving over time.
The unemployment rate is The labor force participation rate is The employment ratio is

Which of the following is NOT a reasonable explanation for the Great Moderation?
higher oil prices
If a country employs many foreign workers, GDP is likely to be
higher than
A sensible question to ask is
how does a change in an exogenous variable affect an endogenous variable?
A country loses much of its capital stock to a war. What effects should this event have on the country's current employment, output, and real wage? This event should cause the country's current employment to decrease (↓), output to decrease (↓), and the real wage to decrease (↓). The loss of capital will cause desired investment to increase (↑). Assume that the desired saving function doesn't change. The loss of capital will cause the country's real interest rate and the quantity of investment to increase (↑).

Money is said to be neutral if: After prices adjust, money is neutral in the IS-LM model because: Regarding neutrality of money:
if a change in the money supply changes the price level and other nominal variables but has no effect on real variables. any change in money supply that shifts the LM curve is finally matched by a proportional change in the price level that shifts the LM curve to its original position. classical economists believe that money is neutral in both the short run and the long run, but Keynesians believe that money is neutral only in the long run but not in the short run due to sluggish adjustment of the price level in the short run.

Suppose the government levies a lump-sum tax on workers. Which of the following best explains the effect on the supply of labor?
A lump-sum tax has only an income effect, so increasing the tax will cause the supply of labor to increase.
Define the velocity of money.
Define the velocity of money. stable
How would each of the following affect Helena Handbasket's supply of labor? The value of Helena's home triples in an unexpectedly hot real estate market. Originally an unskilled worker, Helena acquires skills that give her access to a job with a higher hourly wage. (Assume that her preferences about leisure are not affected by the change in jobs.) A temporary income tax surcharge raises the percentage of her income that she must pay in taxes, for the current year only. (Taxes are proportional to income in Helena's country.)
Helena will supply less labor due to the income effect. The effect on Helena's labor supply is ambiguous because substitution and income effects go in opposite directions in this case. Helena is likely to supply less labor because short-run substitution effects are likely to exceed income effects.

Output per worker, consumption per worker and capital per worker all grow at the same positive rate. IV. Total output, total consumption and total capital all grow at the same rate (the growth of the labor force).
II and IV

How did cigarette shipments affect the price level (the prices of goods in terms of cigarettes) in the POW camp? On some occasions the prisoners knew in advance when the cigarette shipments were to arrive. What happened to the demand for cigarette money and the price level in the camp in the days just before an anticipated shipment?
The price level rose. demand for money declines; the price level rises
When economists say that money is neutral, this means that:
a change in the money supply changes nominal variables but not real variables.

According to the expectations theory of the term structure of interest rates Why isn't the expectations theory sufficient to describe the data on interest rates that we observe?
investors compare bonds with different times to maturity and choose the ones that yield the highest return. on average, long-term interest rates exceed short-term interest rates
What problem does government control of prices create for economists attempting to measure a country's GDP? In countries in which people grow their own food, make their own clothes, and provide services for one another within a family or village group, why might official GDP figures underestimate these nations' actual GDPs?
prices do not measure market value such goods and services are not sold on the market, making their value difficult to measure
Since U.S. investment is generally higher than U.S. national saving:
the U.S. current account balance is generally negative.
