the central bank purchases bonds and the interest rate decreases.

The equation relating investment to the capital stock tell us that

the change in the capital stock equals investment minus depreciation.

People hold more money when nominal income increases because

the dollar value of transactions increases

Changes in the interest rate have a larger impact on investment when

the economy is near full employment.

The natural level of output is the level of output that occurs when

the economy is operating at the unemployment rate consistent with both the wage-setting and price-setting equations.

In the following production function, Y=f(K,NA), suppose A increases by 20%. This 20% increase in A implies that

the effective quantity of labor has increased by 20%.

Unlike the assumption in the previous chapter, in the AD-AS model

the expected price level does not necessarily equal the actual price level.

Suppose the economy is in a situation where Y < Yn.

the expected price level will decrease

In the original Phillips curve relating inflation to unemployment

the expected rate of inflation was assumed to be zero.

Assume the economy is initially operating at the natural level of output. Now suppose there is an increase in government spending (or a reduction in taxes, increase in autonomous investment, etc.). Then (you will need to think about how the IS-LM and AD-AS models work together to answer this question)

the fall in investment will be larger in the medium run as compared to the short-run.

Starting from a medium run equilibrium in the AD-AS model, suppose there is an increase in the price of oil. Then

the growth of investment per worker is zero.

When the economy is operating at the steady state

the growth of saving per worker is zero.

The most often used measure of changing living standards is

the growth rate of real GDP per capita.

At equilibrium in the growth model with technological progress, the growth rate of output per worker, i.e. that growth in the standard of living, is

the growth rate of technological progress.

When the economy is operating at the steady state,

the growth rate of the capital stock per worker is zero.

Suppose there are two countries that are identical in every way with the following exception: Country A has a lower depreciation rate (δ) than country B. Given this information, we know with certainty that

the growth rate will be the same in the two countries.

Starting from a medium run equilibrium in the AD-AS model, suppose there is an increase in the price of oil. Then

the increase in prices will be larger in the medium run as compared to the short-run.

The opportunity cost of holding money increases when

the interest rate increases

Assume the economy is initially operating at the natural level of output. Now suppose there is an increase in government spending (or a reduction in taxes, increase in autonomous investment, etc.). At the new medium run equilibrium (you will need to think about how the IS-LM and AD-AS models work together to answer this question)

the interest rate will be higher, and investment will be lower.

Assume the economy is initially operating at the natural level of output. Now suppose there is an increase in the money supply. At the new medium run equilibrium (you will need to think about how the IS-LM and AD-AS models work together to answer this question)

the interest rate will be unchanged, and real money balances will be unchanged.

Assume the economy is initially operating at the natural level of output. Now suppose there is an increase in the money supply. In the short-run (you will need to think about how the IS-LM and AD-AS models work together to answer this question)

the interest rate will decrease, and real money balances will increase.

Suppose the economy is operating on the LM curve but not on the IS curve. Given this information, we know that

the money market and bond markets are in equilibrium and the goods market is not in equilibrium.

When the MPC goes down

the multiplier falls the IS curve becomes steeper

When the interest rate increases

the opportunity cost of holding money goes up and less money is held

In the equation for the consumption function, C = c0 + c1(Y - T)

the parameter c0 is autonomous consumption

In the equation for the consumption function, C = c0 + c1(Y - T)

the parameter c1 is the marginal propensity to consume

"Convergence" has been occurring among the OECD countries because

the poorer countries have had higher growth rates than the richer ones.

At equilibrium in the growth model with technological progress, the growth rate of output equals

the population growth rate plus the growth rate of technological progress.

Suppose the economy is in a situation where Y > Yn. Then

the price level will tend to increase.

Suppose individuals wish to obtain the most accurate comparison of living standards between the United States and Saudi Arabia. To do so, one would convert Saudi Arabian output into dollars using

the purchasing power parity method.

For this question, assume that the expected rate of inflation is equal to last year's inflation. Also assume that the unemployment rate has been greater than the natural rate of unemployment for a number of years. Given this information, we know that

the rate of inflation should steadily decrease

In the following production function, Y=f(K,NA), suppose A increases by 20%. This 20% increase in A implies that

the same output can be produced with 20% less labor.

In most countries

the saving rate is below the rate given by the golden rule.

The "golden rule" tells us

the saving rate that maximizes consumption.

Disposable income equals

the sum of consumption and saving

The labor force in the United States is defined as

the sum of the total number of individuals who are employed and the officially unemployed

Which of the following is not a means of measuring GDP

the total value of consumption.

The term "reservation wage" refers to

the wage that makes workers indifferent between work and leisure.

We study macroeconomic aggregates such as GDP and the price level because

they represent the average behavior of prices and output across the economy

In the late 1970s, there was disagreement about the costs of fighting inflation. Some argued it would be costly, others disagreed. Looking back at the evidence,

those who argued it would be costly were correct.

In the wage-setting equation, the nominal wage tends to decrease when

unemployment benefits decrease.

The bargaining power of workers increases when

unemployment compensation is improved

In the 45-degree line diagram, when the economy is at equilibrium

unintended inventories are zero

In the Phillips curve equation, an increase in expected inflation increases actual inflation because

wage earners will demand higher wages, firms raise prices to cover the wage increases, and that causes inflation to increase.

The original Phillips curve, which was based upon British data, identified a relationship between

wage growth and unemployment.

An individual is said to be a discouraged worker if he or she

wants to work, but has given up searching for a job.

Assume that individuals form expectations of inflation according to πte=θπt−1. The value of θ for this equation

was zero until the 1970s, then increased steadily to one.

During the Great Recession, the Phillips curve broke down

when inflation did not fall as much as predicted, perhaps due to nominal wage rigidity.

Investment is inversely related to the interest rate because

when the interest rate increases, expected profit on investment projects declines

An increase in human capital per worker

will increase steady state consumption per worker.

In the WS-PS diagram, anything that increases z

will shift the WS equation upward.

In the wage-setting equation (WS), W = P^eF(u,z),

z represents bargaining power.

Once the economy has achieved balanced growth, the growth rate of K/NA is

0

Suppose that: - Firm 1 produces wool from raw materials using workers and machines. It sells the wool to firm 2 for $500. - Firm 1 pays its workers $400 leaving $100 in profit (abstract from depreciation cost, etc. for simplicity) - Firm 2 uses the $500 in wool, along with workers and machines, to produce clothing it sells for $700 - Firm 2 pays its workers $120 leaving $80 in profit ($700 - $500 for wool - $120 for wages = $80 profit) Using the sum of incomes approach the calculation for GDP is:

$400 in wages in firm 1 + $100 in profit for firm 1 + $120 in wages for firm 2 + $80 in profit for firm 2 = $700
