We define an evolutionary process of “economic Darwinism” for playing-the-field, symmetric games. The process captures two forces. One is “economic selection”: if current behavior leads to payoff differences, behavior yielding lowest payoff has strictly positive probability of being...

This paper explores an algorithm which serves as a market auctioneer under the following constraints: [i] traders arrive randomly and each sales/purchase order should be executed at the currently posted price (sequential service), [ii] the auctioneer need not know the exact fundamental value of...

Different market settings are considered in a free trade environment, where firms can choose technology, quality, and price or quantity. The shape of competition in prices requires the intervention of governments, via a common antidumping policy to make firms converge on the simultaneous...

We relate the sources of innovation market failure to the dominant mode of sectoral innovation and outline mechanisms for public support of innovation that target specific sources of innovation market failure.

We study the long run e¤ects of transparency in a circular town model of a differentiated market. The market is not fully transparent on the consumer side: A fraction of consumers are uninformed about prices. Increasing transparency reduces the equilibrium price, profit and entry of firms. This...

This paper deals with a general version of a two-stage model of R&D and product market competition. We provide a thorough generalization of previous results on the comparative performance of noncooperative and cooperative R&D, dispensing in particular with ex-post symmetry and linear demand...

We integrate strategic-trade and political-economy considerations in a unified framework to analyse unilateral trade policy. Foreign firms compete on Home's market through export or foreign direct investment (FDI). They also lobby Home's government which sets trade (tariff) and industrial (tax)...

In this paper, we discuss the pros and cons of using Data Envelopment Analysis (DEA) to evaluate and enhance the efficiency of natural resource management. The need for a multi-dimensional production frontier approach is sketched, along with examples from other regulated multi-output industries....

An infinite-horizon, stochastic model of entry and exit with sunk costs and imperfect competition is constructed. Simple examples provide insights into: (1) the relationship between sunk costs and industry concentration, (2) entry when current profits are negative, and (3) the relationship...

We provide an extensive comparison of the R&D models of d'Aspremont-Jacquemin (1988) and Kamien-Muller-Zang (1992), exposing full or partial conflict in key conclusions and policy prescriptions. Using three separate formal and/or intuitive criteria, we argue that the first model is invalid for...
