Using daily panel data from Detroit, we empirically explore the relationship between the National Football League (NFL) and crime in a city. We exploit the natural experiment of the Detroit Lions’ move from Pontiac, Michigan, to downtown Detroit in 2002. Pontiac is used as the treatment city and non-game day crime, other suburban cities, and other cities outside Detroit MSA are used as the comparison groups. Employing a difference-in-difference approach, we find decreases in assaults and vandalism on home game days in Pontiac relative to the control cities after the Lions’ move. We find weak evidence of a net decrease in larceny and vandalism in Pontiac on home game days following the loss of professional football. No changes in assaults and auto theft are reported. While not conclusive, our results suggest that professional football leads to additional larceny and vandalism incidents but no effects on assaults and auto theft. 相似文献

This paper investigates optimal emissions taxation under imperfect competition in a durable good industry where products are sold (instead of rented). As a benchmark, attention is paid to the special case of monopoly with exogenously given product durability. In line with previous literature, the optimal emission tax in this benchmark model falls short of marginal damage (underinternalization). Extending the benchmark model either to the case of an oligopolistic market structure and/or to the case of endogenous product durability then provides two cases in which the optimal emission tax overinternalizes marginal damage. 相似文献

Commercial aquaculture in India has come under attack for having caused negative agricultural and environmental impacts. This paper formulates an interactive model of non-renewable and renewable resources to characterize land allocations between aquaculture and agriculture in ecologically and economically sustainable fashion. Through an empirical application, various economic and policy circumstances that affect the optimal land allocation mix are evaluated. The aquaculture industry must address two economic effects: off-site negative effects on renewable food and other coastal resources, and on-site self-pollution of shrimp ponds. Current regulatory and land-use policies are inadequate to address these effects. 相似文献

Given self-protection from an undesirable environmental externality, we examine, under several conditions, the efficiency properties of cooperative and noncooperative behavior. We demonstrate that if self-protection can transfer the externality to another agent, then noncooperative behavior will lead to overprotection. If self-protection filters or dilutes the externality, then noncooperation leads to underprotection. In addition, overprotection will worsen if an agent with more relative power is allowed a first-mover advantage or if the damage function is elastic and transferability is uncertain. Finally, a reduction in uncertainty about transferability will accentuate overprotection if the damage function is inelastic. Our results suggest that coordination of protection activities among agents will enhance the overall gains from environmental policy in the European Single Internal Market of 1992. Coordination minimizes the costs of environmental protection, thereby reducing the public credibility of its foes. 相似文献

This paper examines the case of a good, polluting in consumption, whose pollutive content is restricted by a government with strong environmental policies. When foreign producers are unable to comply with the restrictive environmental standard of such a country, to which they wish to export, they often allege that those standards constitute illegal barriers to free trade. An example of such a good is gasoline, excessively pollutive formulations of which are prohibited from importation into the United States by the 1970 Clean Air Act. Rather than banning them, such imports should be taxed, along with the domestically produced substitute good, according to their respective pollutant contents. This would foster economic efficiency and should be more acceptable to foreign producers than the outright prohibition mandated by the Clean Air Act. The results of this paper reaffirm the argument in a previous article in this journal (Socio-Economic Planning Sciences 29 (1995) 187), though the countries’ roles in the two papers are reversed, that free trade and Pigouvian environmental policies increase international welfare. 相似文献

外商直接投资是影响东道国就业的重要因素,FDI的进入不仅直接提高对劳动力的需求,还会通过总需求扩张等渠道产生外部性,影响国内就业。本文运用一个寡头模型研究了利用外商直接投资对东道国影响的不同渠道,并利用中国的经验数据进行了分析。结果表明,外商直接投资对总需求的刺激是影响中国就业的主要渠道,外商直接投资拉动中国总需求的作用越大,就越能增加中国国内就业。 相似文献

Pollution externalities between polluters should be taken into account in the design of corrective taxes. When the externalities are substantial and/or the number of polluters is large, the effluent levies on these firms do not necessarily result in a deadweight loss. Consequently, the second-best tax exceeds the marginal social cost of pollution. A more general rule is that the tax rate should be greater than the marginal social cost of pollution if and only if a marginal increase in the tax rate results in opposite effects on the changes of equilibrium emission level and output. 相似文献
