Document Summary

Classical dichotomy: separation into real and nominal. Monetary neutrality: idea that changing nominal variables only changes the price level. Classical theory is based on long run econ and can"t always be applied. Money supply can affect gdp in the short-run. Vertical axis is price level and horizontal axis is output. Demand: shows q of goods and services that households, firms, government and abroad want to buy at any given price level. Supply: given output firms and are willing to produce and sell at a given price level. Total q of all goods produced by all firms in all markets. Decrease in a level of prices raises the q of goods demanded. Y = c + i + g + nx. When price level falls the dollars people have either increase or decrease in purchasing power which is real. Decrease in price level raises the real value of money which makes the consumers wealthier which makes them want to spend more.

Related Questions

1. If the price level doubles and the real output doesn't change, then nominal output also doubles.
2. Inflation makes it less difficult to interpret the information conveyed by prices.

3. Laissez-faire economists oppose government intervention in the market process.

4. Active demand management policies are based on the work of JohnMaynard Keynes.

5. In the AS/AD model, as the price level rises, the real value of assets increases, causing consumption to increase. This is one reason why the aggregate demand curve slopes down.

6. The short-run aggregate supply curve is upward sloping in part because increases in aggregate demand cause some firms to increase their price markups.

7. If productivity and wages both raises by 3 percent, then the short-run aggregate supply curve does not shift.

8. The long-run aggregate supply curve is vertical because all prices adjust in the long run.

9. If the economy is not in long-run equilibrium and other things are equal, then prices will eventually adjust to bring the economy to long-run equilibrium.

10. Most economists agree that it is possible for fiscal policy to fine-tune the economy.

E) no change in the natural rate of unemployment.

5) In the aggregate demand relation, a reduction in the price level causes output to increase because of its effect on:

B) the nominal wage.

C) the interest rate.

D) the expected price level.

6) The short-run aggregate supply curve (AS) is upward sloping because:

B) a reduction in the aggregate price level causes a reduction in nominal money demand and a reduction in the interest rate.

C) a reduction in the aggregate price level (P) will cause a reduction in the interest rate and an increase in output.

D) an increase in the aggregate price level will cause an increase in the interest rate and a reduction in output.

E) an increase in the nominal wage causes a reduction in the amount of output that firms are willing to produce.

7) Assume that the economy is initially operating at the natural level of output. A simultaneous expansionary monetary policy and an increase in oil prices will cause which of the following?

C) a reduction in output and a reduction in the interest rate in the short run

D) an ambiguous effect in output and an increase in the price level in the short run

E) an ambiguous effect in output and a reduction in the price level in the short run

8) Assume that the economy is initially operating at the natural level of output. A one-time 4% reduction in the nominal money supply will cause:

A) a 4% increase in the price level in the medium run.

C) a 4% increase in the real money supply in the medium run.

D) a 4% increase in the interest rate (i) in the medium run.

9) The original Phillips curve implied that:

A) the markup over labor costs is zero.

B) the expected inflation rate is equal to last year's inflation rate.

C) a lower rate of unemployment causes an increase in the rate of inflation.

D) the inflation is always zero.

B) a rise in the expected inflation rate

C) a rise in the employment insurance

D) a drop in the markup

E) a fall in the unemployment rate
