We show that adaptive measures undertaken by countries in the face of climate change, apart from directly reducing the damage caused by climate change, may also indirectly mitigate greenhouse gas emissions by increasing the stable size of international agreements on emission reductions....

Within a non-cooperative transboundary pollution game, we investigate the impact of the adoption of a cleaner technology (i.e., a decrease in the emission to output ratio). We show that countries may respond by increasing their emissions resulting in an increase in the stock of pollution that...

We show that the imposition of a Markovian tax on emissions, that is, a tax rate which depends on the pollution stock, can induce stable cartelization in an oligopolistic polluting industry. This does not hold for a uniform tax. Thus, accounting for the feedback effect that exists within a...

In the absence of a successful international cooperative agreement over the control of emissions there is a growing interest in the role that clean technologies may play to alleviate the climate change problem. Within a non-cooperative transboundary pollution game, we investigate, analytically...

We analyze the effects of bilateral tariff reductions on the profitability of cost-reducing horizontal mergers. Given Cournot competition in a two-country world, for any positive tariff below a certain threshold, marginal trade liberalization is shown to encourage only those domestic mergers...

This is a revised version of the paper first published in February 2008.In a two-country model where firms behave agrave; la Cournot, we show that marginal and non-marginal trade liberalization have different effects on the social desirability of horizontal mergers. Marginal tariff reductions...

We document that immigration to U.S. states has increased the mass of workers at the lower range of the skill distribution. We use this change in skill distribution of workers to analyze the effect of immigration on wages. Our model allows firms to endogenously respond to the immigration-induced...
