Aggregate Demand and Aggregate Supply Aggregate Demand (AD) Aggregate demand is the total demand in an economy, and it can be referred to as the total expenditure in the economy. In the Keynesian system, increases in aggregate demand lead to increases in output because the money wage rises less than proportionately with the price level in response to such increases in demand. The aggregate supply curve (AS) is horizontal at GDP levels less than potential, and vertical once Yp is reached. aggregate supply and demand analysis sketched in the General Theory.
