An increase in the unemployment rate decreases the opportunity cost of crime and increases the crime rate according to standard microeconomics models. However, a large body of empirical research has shown that an increase in unemployment may increase or decrease crime. By incorporating the return to crime into standard economic models, this paper shows that an increase in unemployment, as in recessions, decreases the opportunity cost of crime and the return to crime as well. As a result, the effect of unemployment on crime is ambiguous and depends on the apprehension rate. An increase in the unemployment rate tends to decrease the crime rate at lower apprehension rates, but to increase it at higher apprehension rates. An increase in the generosity of unemployment insurance benefits does not necessarily reduce the crime rate, and the effect of more generous unemployment insurance on crime depends again on the apprehension rate. 相似文献

This preliminary study seeks to identify some of the factors responsible for the hitherto limited success of the National School of Public Administration in Greece, which became operational in 1985. The School, modeled after the National School of Public Administration (ENA) in France, annually accepts into its four specialized tracks with their common core curriculum both civil servants and private citizens who succeed in its rigorous entrance competitions. The School represents an effort to identify administrative talent and offer specialized training in public administration toward upgrading the administrative capabilities of the Greek civil service. Some tentative conclusions point out that the limited success of the School is associated with its brief life span, its only partial acceptance by the unions of higher civil servants, its relatively legalistic program orientation, its inadequate emphasis on internships or learning by doing, the non-strategic placement of graduates, and the absence of an identifiable corps of administrative generalists readily transferable from department to department. Perhaps, the foremost constraining factors are to be found in the areas of limited resources, brief periods of experimentation, and limited adaptation of a French prototype to the current realities of the Greek civil service. 相似文献
