International R&D formations and strategic environmental policy

We examine relations between strategic environmental policy, international R&D cartels and research joint ventures (RJVs), using a third-country model with Cournot duopoly. We indicate that forming an R&D/RJV cartel reduces governments' incentives to extract rent from consumers in the third country. Contrary to conventional wisdom, we find that social welfare under R&D cartels with full information sharing, i.e., RJV cartels, cannot surpass that under R&D/RJV competition, whereas forming an R&D/RJV cartel works well for environmental investment. Among the policy implications, we show that governments can maximize global welfare by collectively determining whether to allow R&D/RJV cartels.
