This paper investigates the welfare effects of international transfers of environmental technologies in open economies with international oligopoly and transboundary pollution, and shows that policy differentiation between the donor and recipient countries and/or product differentiation between...

This paper investigates firm incentives for developing environmentally clean technologies in a simple two-country model with international oligopoly, and compares them under price and quantity regulations with and without policy cooperation between governments. Under any policy regime, whether...

In this paper we reconsider the completely crowding-out effect in a model of the private provision of public goods with non-linear technology for government contributions. Even though there are no free-riders, government contributions financed by lump-sum taxes crowd out private contributions...

This paper investigates the welfare effects of unilateral or multilateral technological progress in a world with global public goods. We focus on the consumption relation between the private and the public good, and then show that technological progress may be“self-centered” (benefit oneself...

In this paper we reconsider the completely crowding-out effect in a model of the private provision of public goods with non-linear technology for government contributions. Even though there are no free-riders, government contributions financed by lump-sum taxes crowd out private contributions...

Using a simple two-group model of the private provision of public goods, this paper investigates how endogenous formation of within-group cooperation is affected by different types and degrees of between-group interactions. We show that when between-group interactions are of the same directions...

In this paper, we characterize optimal environmental policy in a case where innovation in clean production technologies is developed and provided by a monopoly. Two policy instruments are considered: an emission tax on downstream polluting firms and an R& D subsidy for an upstream innovator in...

Using a team-production model with heterogeneous workers, we examine the short- and long-run efficiency effects of skill diversity and leadership in teams. Our analysis focuses on workers' strategic incentives to manipulate their skills. In the short run, heterogeneous pairing (pairing workers...

We investigate the social desirability of free entry in the co-opetition model in which firms compete in a homogeneous product market while sharing common property resources that affect market size or consumers' willingness to pay for products. We show that free entry leads to socially excessive...

Using a simple two-group model of the private provision of public goods, this paper investigates the endogenous formation of within-group cooperation. We show that the equilibrium outcomes may result in a prisoners’ dilemma, depending on the characteristics of between-group externalities. If...
