Assume the short-run aggregate supply curve can be expressed algebraically as: YS=4,200+4,000, where YS is aggregate supply. And the dynamic aggregate demand curve can be written as: Yd=4,3001,000, where Yd is aggregate demand. Find the numerical value for equilibrium output, Y, in the short run. Find the numerical value, in percent, for the short-run inflation rate, . Instructions. Enter your response as a whole number %
