Workers and firms adjust their expectations of wages and prices upward and they push for higher wages and prices

On the​ long-run aggregate supply​ curve,

a decrease in the price level has no effect on the aggregate quantity of GDP supplied.

Because of the slope of the aggregate demand curve, we can say that

a decrease in the price level leads to a higher level of real GDP demanded.

decrease aggregate demand.

An increase in the price level results in a(n) ________ in the quantity of real GDP demanded because ________.

decrease; a higher price level reduces consumption, investment, and net exports.

A decrease in investment causes the price level to ________ in the short run and ________ in the long run.

decrease; decrease further

increase; decrease to its initial value

After an unexpected _____ in the price of oil, the long-run adjustment decreases the price level and _____ the unemployment rate as they return to their original levels.

increase; decreases

According to the real business cycle model

increases in aggregate demand do not affect GDP.

Stagflation occurs when

inflation rises and GDP falls.

The "interest rate effect" can be described as an increase in the price level that raises the interest rate and chokes off

The long-run aggregate supply curve

is vertical.

short-term fluctuations in real GDP and the price level.

The new Keynesians emphasize the importance of

sticky wages and prices
