We derive a simple expression for the income-pollution path using the standard static model of the environmental Kuznets curve (EKC). This expression makes it straightforward to identify the general characteristics of utility and pollution functions that lead to such a curve. We show that...

Analyzing county level data for the entire United States from 1977 to 2000, we find annual reductions in murder rates between 1.5 and 2.3 percent for each additional year that a right-to-carry law is in effect. For the first five years that such a law is in effect, the total benefit from reduced...

An analysis of the effects of right-to-carry laws on crime requires particular distributional and structural considerations. First, because of the count nature of crime data and the low number of expected instances per observation in the most appropriate data, least-squares methods yield...

Researchers often report point estimates of turning point(s) obtained in polynomial regression models but rarely assess the precision of these estimates. We discuss three methods to assess the precision of such turning point estimates. The first is the delta method that leads to a normal...
