We study whether a government-sponsored voluntary pollution reduction program (VPR) promotes or deters the development of new environmental technologies that yield future emission reduction benefits. Using a panel of 127 U.S. manufacturing industries defined by 3-digit SIC classifications over...

By estimating a simultaneous panel data model of environmental innovation and toxic air pollution, this paper identifies bi-directional causal links between the two. We study a panel of 127 manufacturing industries over the period 1989-2004. Pollutant emissions are an implicit measure of policy...
