Using US data from 1977-1986, we estimate the impact of environmental policy on state-level output using parametric and nonparametric techniques. While the nonparametric approach yields additional insights, the lack of a relationship between environmental regulation and output is robust

In this paper nonparametric techniques are used to estimate higher-order moments of technical efficiency. The procedures developed in this paper allow the moments to be estimated with relative ease, while at the same not requiring restrictive assumptions on the distribution of inefficiency. The...

Keller and Levinson (2002) utilize state-level panel data on inflows of foreign direct investment along with an innovative measure of relative pollution abatement costs to assess the impact of environmental stringency on capital flows. Using standard parametric panel data models, the authors...
