To increase the money supply, the Fed could
decrease in the required reserve ratio
To fight a recession, Congress and the president should
decrease taxes to increase aggregate demand.
In the long run, a decrease in the money supply will
decrease the price level.

decrease, then consumption increases, and aggregate demand shifts rightward.
To keep the budget balanced during the recession when tax revenue is low and government purchase is high, the federal government must _________ government spending, or ________ taxes, and which will ________ aggregate demand.
decrease; increase; reduce
The Fed initiates a contractionary monetary policy that is correctly anticipated by economic agents in the economy. The result is
decreased prices, but no change in real GDP.
If the Fed conducts open-market sales, the money supply
decreases and aggregate demand shifts left.
Suppose government spending is cut. Other things being equal, the aggregate demand for national production will
fall

fall and thereby increase aggregate demand.
Suppose an economy produces only ice cream cones. If the price level rises, the value of currency
falls, because one unit of currency buys fewer ice cream cones.
If aggregate demand shifts right then in the short run
firms will increase production. In the long run increased price expectations shift the short-run aggregate supply curve to the left.
Aggregate demand shifts right if
government purchases increase and shifts left if stock prices fall
Money demand refers to

increase the price level only.
Open-market purchases by the Fed make the money supply
increase, which makes the value of money decrease.
An increase in government spending
increases the interest rate and so investment spending decreases.

If businesses and consumers become pessimistic, the Federal Reserve can attempt to reduce the impact on the price level and real GDP by
increasing the money supply, which lowers interest rates.
According to monetary neutrality and the Fisher effect, an increase in the money supply growth rate eventually increases
inflation and nominal interest rates, but does not change real interest rates.

nominal income increased, but their real income decreased
Monetary policy in Japan since the early 1990s has had limited effectiveness even though the Bank of Japan lowered
nominal interest rates to almost zero, because deflation (a negative rate of inflation) kept real interest rates up.
