This paper investigates the effectiveness of New Jersey's mandatory belt use law (MUL) by testing specifically for: (1) a safety effect, and (2) a risk-compensation effect that could offset (in part) any safety impact. The main findings are that injury severity declined significantly in the 22 months following implementation of the MUL; but that accident frequency increased significantly. The increase in accidents may be explained only partially by increased driving mileage. These findings suggest that the real safety effect of the law may have been diluted by risk-compensating behavior.This paper is based on a study conducted for the New Jersey Office of Highway Traffic Safety by the Rutgers University Bureau of Economic Research. We are grateful to William Ascher and two referees for useful comments. 相似文献

Federalism has not been a resounding success in Africa, althoughunitary regimes have had no better record One promising politicalsystem has been the consistently federal and periodically democraticgovernment of Nigeria. The principal challenges facing Nigeria,which are not unlike those facing other heterogeneous Africancountries, are national unity, democratic politics, and socioeconomicdevelopment. Examined here are the nature of these challenges,Nigeria's responses, potential alternatives, and possible implicationsof Nigeria's experience for federal democracy in Africa. 相似文献

In recent yems, rapid growth hm occurred in both the number and diversity of university-industry progrmns in the United States. While little comprehensive assessment of these programs exists to date, this paper argues that a systematic empirical analysis of a cmpany's perception of universities as knowledge sources is critical toa clear understanding of the newallknces between industry and academia. From a survey of216 companies, a pattern emerges where the sources of technical knowledge perceived as important by industry are complex and highly interrelated, and they also vary according to the characteristics of companies, especially size. It is seen that university research rather than universities as institutions per se are critical ingredients to the development of new products and production processes. 相似文献
