Comportamento dei soggetti e regolamentazione nella teoria della politica economica
Abstract Models of economic policy are usually based on the «targets-tools» scheme. They concentrate on the tools which regulate aggregate demand such as fiscal policy, monetary and credit policy, exchange-rate policy. But they overlook the reactions of the agents of the economic system, and particularly of organized social groups, to economic policies; they overlook the decision-making process of government and of the public entities which put in practice economic policies; and they do not consider the supply factors.Analyzing these points, this article shows how the reactions of the agents can be embodied in an analytical model. It shows also how basic the analysis of the governmental decision-making process is to evaluate the efficiency and the impact of economic policies. Finally it shows how largely supply is determined by legal and administrative factors. In conclusion, regulation (or deregulation) is a very important instrumental variable which needs to be embodied into the models of economic policy.
