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 analysis provides a re-appraisal of the 1899 Hague Conference by looking more closely at how citizen activists—notably in Britain but also transnationally—used it as a forum through which to press their agenda onto politicians and diplomatists. In so doing, this assembly existed as a stepping-stone between the ‘old’ diplomacy of the nineteenth century and the ‘new’ diplomacy of the twentieth. Peace activists identified and harnessed a growing body of progressive public opinion—on both a domestic and international scale—in the hope of compelling governments to take the necessary steps towards realising their ambitions of peace, disarmament, and international arbitration. Although the tangible outcomes of the 1899 Conference were limited, the precedents it established not only paved the way for further advances in international law, but also facilitated ever closer public and press scrutiny of international affairs into the twentieth century.  相似文献

SUMMARY

In this article, Maria Sofia Corciulo analyses the political significance of the period of the Italian Restoration. The author suggests that the revolutions which took place in both Naples and Piedmont in 1820–21 affected the apparently static institutional tranquillity of the ‘restored’ Italy to such an extent that they represent a break from the preceding period—the Five-year Period, during which the Napoleonic institutions had been, anyway, partly retained. The revolutionary action which, as in Spain, was sparked by the military, was characterized by forms of participation and aims that constituted, at least where they could be fully expressed, the beginning of a new historical period, surely overshadowing that of Restoration: the Risorgimento. The Neapolitan Revolution was carried out under the banner of the most democratic principles of those years, as they had been sanctioned by the Constitution of Cadiz of 1812. Although the Italian revolutionaries of 1820–21 were defeated, the principles of the Cadiz Constitution remained vivid in the minds of the patriots, especially Neapolitans, in an intricate sectarian world, where even the participation of the most humble classes was welcome and accepted in the name of the egalitarian principles of the Carboneria. The article suggests that this Revolution spelled the de facto end of the Restoration, even it was to continue to exist de jure, in its limited dynastic sense. This is true not only for the Kingdom of the two Sicilies but also for the other Italian states, because so-called ‘public opinion’ became a reality in this period: the existence of political plots and conspiracies from a rising number of secret societies is clear evidence that Italy's Risorgimento was under way.  相似文献
