Using analytical and numerical general equilibrium models, we show that preexisting factor taxes produce a "tax-interaction effect" that increases the costs of pollution taxes and quotas. Under policies that raise revenue and recycle it through cuts in marginal factor tax rates, this effect is...

Many pollution-related industries have political influence sufficient to block policies that would harm their profits. A politically realistic approach to environmental policy seems to require avoiding significant profit-losses to these industries. Using analytically and numerically solved...

This article studies several attributes of a firm's long-run decisions about organizational structure, attributes that affect the firm's short-run innovative activity. We focus on flexibility, which lowers the future costs of implementing innovations, and research capabilities, which improve the...

We analyze a model of oligopolistic competition with ongoing investment. Special cases include incremental investment, patent races, learning by doing, and network externalities. We investigate circumstances under which a firm with low costs or high quality will extend its initial lead through...
