Beginnings of the New Classical Macroeconomics

Even though its name suggests a negative response of Keynesian economics and a revitalization of classical economics, the new classical macroeconomics started with Lucas’s and Leonard Rapping’s go to provide micro foundations for the Keynesian labor market. Lucas and Rapping functional the rule that equilibrium in a market happens when quantity supplied equals amount demanded. This turned out to be a fundamental step. Since involuntary unemployment is precisely the situation in which the amount of labor supplied goes beyond the amount demanded, their analysis leaves no room at all for instinctive unemployment.

Keynes’s view was that recessions happen when aggregate demand falls largely as the consequence of a fall in private investment causing compacts to produce under their capacity. Producing less, firms require fewer workers, and consequently employment falls. Firms, for causes that Keynesian economists go on to debate, fail to cut wages to as low a level as job seekers will accept, and so involuntary unemployment grows. The new classical reject this step as illogical. Unintentional unemployment would present firms with a chance to raise profits by paying workers a lower wage. If firms botched to take the opportunity, then they would not be optimizing. Employed workers should not be capable to resist such wage cuts successfully since the unemployed stand ready to take their rests at the lower wage. Keynesian economics would appear, then, to rest either on market deficiencies or on irrationality, both of which Keynes denied.

These disparagements of Keynesian economics demonstrate the two fundamental tenets of the new classical macroeconomics. Primary, individuals are viewed as optimizers: given the costs, as well as wage rates, they face and the assets they hold, together with their education and training (or “human capital”), they prefer the best options obtainable. Firms maximize profits; people maximize value. Second, to a first prices adjust, approximation, varying the incentives to individuals and thereby their choices, to support quantities supplied and demanded.
