Environmental Research Joint Ventures and Time-Consistent Emission Tax

Symmetric Research Joint Ventures

We introduce the concept of cooperative substitutes and complements, and use it to throw light on the conditions for a research joint venture to choose equal levels of R&D by all member firms. We show that the second-order conditions for a symmetric optimum take a particularly simple form, ruling out both excessive cooperative substitutability and excessive cooperative complementarity, and nest...

Joint Ventures, Pollution and Environmental Policy

We examine the impact of abatement taxes on the pollution level in a duopoly framework with endogenous market structure. We demonstrate that an increase in abatement taxes could trigger a regime-switch from joint ventures to Cournot competition, causing the pollution level to increase. Moreover, abatement taxes can implement the first best outcome if and only if the industry is not too pollutin...

Coordinating research through research joint ventures

In a simple model, we show that a joint venture can implement the rates of investment that maximize joint profit when firms’ research abilities are private information. This can be done with budget balance, even though there are participation constraints. There is no conflict between budget balance and participation constraints because firms’ payoffs can depend on ex post signals of abilities. ...

Research Joint Ventures, Innovation, and Multiproduct Competition

Joint design of Emission Tax and Trading

This paper analyzes the joint design of fiscal and cap-and-trade instruments in climate policies under uncertainty. Whether the optimal mechanism is a mixed policy (with some firms subject to a tax and others to a cap-and-trade) or a uniform one (with all firms subject to the same instrument) depends on parameters reflecting preferences, production, and, most importantly, the stochastic structu...
