Classical economists believed that supply creates its own demand (Say's Law), but Keynes argued that the actual level of output and employment in an economy is determined by the level of aggregate demand that firms expect to receive.
Effective demand is not just any level of demand—it's the specific point where what buyers plan to purchase (aggregate demand) exactly matches what producers plan to supply (aggregate supply). At this intersection, the economy settles into equilibrium. Firms have no incentive to expand or contract production because they're selling exactly what they anticipated, and there's no unintended accumulation or depletion of inventories.
Think of it this way: if aggregate demand exceeds aggregate supply at the current output level, firms see their inventories falling and respond by increasing production. Conversely, if aggregate demand falls short, unsold goods pile up and firms cut back. Only at the point of effective demand—where —does the economy find a stable resting point. …
