This paper reexamines the issues of compliance with and enforcement of the minimum wage law recently addressed in this Journal by Ashenfelter and Smith and by Grenier. Pursuing a more rigorous methodology we are able to add new general conclusions, and correct and reconcile some previous...

This paper examines the economic and political implications of two market-based policies, eco-certifications and emission taxes. We evaluate each policy's effects on the environment, investment in clean technology, and social welfare under imperfect competition. We find that eco-certification...

We develop a vertical differentiation model to analyze welfare implications of environmental policies in a competitive market with production and consumption heterogeneity. Consumers with heterogeneous preferences choose between non-green and certified green products, while producers with...

This paper analyzes and compares differences in policy implications between import tariffs and antidumping (AD) duties in the presence of dumping under free trade. We present a vertical differentiation model of international trade in "like" products under duopolistic competition, allowing for...

This paper examines which types of firms, from a developed country (DC) or a less developed country (LDC), tend to practice dumping, using a two-market equilibrium analysis of trade in "like" products. Specifically, we present a vertical product differentiation model of duopolistic competition...

This paper examines the welfare implications of corporate social responsibility (CSR) in international markets under imperfect competition. Based on a stylized model of an import-competing duopolistic market, we show the feasibility of moving toward tariff reductions when both domestic and...

This article discusses the contributions and limitations of the contest approach to theoretical conflict research. Specific topics of discussion include the persistence of war and the motivation and effect of third-party intervention in altering the outcome and persistence of conflict. The...

This paper examines how Bertrand competition affects the welfare implications of bundling by a multi-product firm, which is a monopoly over one good and faces a single-product competitor in a second good. We find that the equilibrium bundle price is lower than the sum of the prices of the two...
