Suppose that changes in aggregate demand tended to be infrequent and that it takes a long time for the economy to return to long-run output. How would this affect the arguments of those who oppose using policy to stabilize output?

Those who oppose stabilization policy mostly argue that by the time policy can be put into action and affect aggregate demand, economic conditions may have changed so that the policy is no longer appropriate. If the economy tended to stay on one side of the natural rate of output for a long time, policymakers could worry less about lags.
