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...

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...

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...

The efficiency of mechanisms to control activities with negative externalities is limited by uncertainty about the social costs of these activities. Existing regulatory mechanisms require negotiated compromise about either the prices of activities or the levels to be tolerated. We offer a...
