This paper demonstrates that the standard conclusions regarding the comparison of Cournot and Bertrand competition are reversed in a vertically related market with upstream monopoly and trading via two-part tariffs. In such a market, downstream Cournot competition yields higher output, lower...

We study firms' advertising strategies in an oligopolistic market in which both non-comparative and comparative advertising are present. We show that in equilibrium firms mix over the two types of advertising, with the intensity of comparative advertising exceeding that of non-comparative...

This paper provides sufficient conditions under which the negotiated wage in unionized oligopolistic industries with centralized negotiations is independent of a number of product market features (such as the number of firms, the degree of product substitutability, or the type of market...

This paper investigates the effect of credibility of environmental policies on environmental innovation and welfare. When the government precommits to an emission tax, the monopolist's abatement effort is lower than if the environmental policy is at the government's discretion. Time consistent...

This paper investigates the determinants of a responsible multinational firm's decision to enter in a foreign country either through exports or through foreign direct investment (FDI), as well as the relevant market and societal outcomes. We find that CSR investments are higher under FDI than...
