This paper develops a monopolistic competition model to study the characteristics of products, such as quality improvement and product diversity (function-specialization and individualization), and the division of labor in production. Different from the ordinary economic model, our utility...

This paper shows that, unlike what has been found in other papers, a hydro reservoir is an effective tool to exercise market power. Its appealing as a tool is enhanced by the fact that there is no need to constrain total hydro production - a practice too easy to detect -; it suffices to distort...

The analysis of economies of specialization at the individual level by Yang & Shi (1992) and Yang & Ng (1993) is combined with the Dixit & Stiglitz (1977) analysis of monopolistic-competitive firms to show that, ignoring administrative costs and indirect effects (such as rent-seeking), even if...

We analyse vertical integration when there is upstream competition and compare outcomes to the case where upstream assets are owned by a single agent (i.e., upstream monopoly). In so doing, we make two contributions to the modelling of strategic vertical integration. First, we base industry...

This paper reverses the standard order between input supply negotiations and downstream competition and assumes that competition for orders takes place prior to procurement of inputs in a vertical chain. In an environment where procurement negotiations involve no private information and no...

We take the view that alternative trading opportunities may influence the loss to delay in a bargaining situation, and show that contractual exclusivity may then be relevant even for ‘internal’ investments, contradicting a recent finding by Segal and Whinston (2000). When a buyer is an...

We develop a model in which firms set their salary levels before matching with workers. Wages fall relative to any competitive equilibrium while profits rise almost as much, implying little inefficiency. Furthermore, the best firms gain the most from the system while wages become compressed. We...

Cournot oligopoly has been studied almost exclusively under the implicit assumption of perfectly competitive factor markets. However,oligopolistic firms procure often factors of production from imperfectly competitive markets. Okuguchi(1998,2000) has analyzed Cournot oligopoly under the...

This paper examines the relationship between input sector liberalization and product quality innovation and export orientation by a LDC firm given the complementarity between high input quality and high product quality. We show that input sector liberalization per se may not induce quality...

We describe a two-step algorithm for estimating dynamic games where the agents are assumed to play a Markov Perfect equilibrium. In the first step, the policy functions and the law of motion for the state variables are estimated. In the second step, the remaining structural parameters are...
