Suppose the economy is initially in equilibrium where real GDP equals potential GDP and the inflation rate is at the target rate.Other things equal,a housing boom will cause aggregate expenditures to increase,which will result in a new,short-run equilibrium.To return GDP to its potential level,the inflation rate will adjust.With adaptive expectations,this moves the economy to another new short-run equilibrium point.Since the housing boom is temporary,the end of the housing boom will now cause
