One difficulty with any explanation of economic fluctuations based on a shift in labor
supply is that
a. workers’ preferences tend to change very quickly
b. labor supply shifts all the time without causing recessions or expansions
c. labor supply is difficult to measure
d. workers’ preferences tend to change very slowly
e. the unemployment rate changes during economic fluctuations
In the aggregate demand-aggregate supply model, an increase in the price level will
a. increase money demand, raise the interest rate, reduce aggregate expenditure, and
decrease equilibrium real GDP
b. decrease money demand, lower the interest rate, increase aggregate expenditure, and
increase real GDP
c. increase the money supply, lower the interest rate, increase aggregate expenditure,
and increase real GDP
d. decrease the money supply, raise the interest rate, reduce aggregate expenditure, and
decrease real GDP
e. not change money supply, money demand or the interest rate, but will shift the
aggregate demand curve to the right
