The authors develop a model in which the benefit of language acquisition is increasing in the number of individuals who speak the language. This gives rise to a network externality and, if language acquisition is costly, the language acquisition decisions by individuals may be inefficient. If...

Empirical evidence suggests that past levels of protection are significant determinants of current levels of protection. We investigate dynamic interactions among interest groups and resulting endogenous links between current and future trade policies. We explore these intertemporal links in a...

We re-examine the regulatory role of a public firm in an environment of private but correlated information about industry costs. We study three regimes of mixed-market interaction involving both public and private firms: a symmetric Bayesian-Nash equilibrium, an asymmetric Bayesian equilibrium...

A model of sequential entry with Leontief costs is studied in which demand is isoelastic. Some or all firms may hold excess capacity in the perfect equilibrium to the entry game. Firms with a first-mover advantage trade off the positioning value of a large investment in capacity, leading to a...
