Design of environmental regulation has substantial implications for size distribution and mass of firms within and across industries in the long run. In a general equilibrium model that accounts for endogenous entry and exit of heterogeneous firms, the welfare impacts of emissions trading are...

We investigate the long-run impact of environmental regulations on the intra-industry distribution of firm-level productivity and the resulting aggregate variables. In a general-equilibrium model that accounts for endogenous entry/exit of heterogeneous firms, neither the average productivity of...

The purpose of this paper is to determine what types of information may be important in determining the welfare benefits of preventing toxic water contamination when a given type of toxification occurs (or is likely to occur) in a given setting. It attempts to identify information and behavior...

This paper identifies information that may be important in determining the benefits ofpreventing toxic water contamination (or equivalently cost of nonaction) when a given toxificationoccurs. It attempts to identify information and behavior issues that need to be considered when weestimate...
