This paper develops a general equilibrium model of international trade with heterogeneous firms and imperfect credit markets. To finance the costs for product innovation and domestic and foreign market entry, firms must raise external capital. The model underscores the importance of considering...

In the framework Hotelling-Downs competition two players can freely choose a position along a one-dimensional market. We introduce restrictions of feasible strategies and analyze the consequences for players and consumers. In equilibrium players may minimally differentiate away from the center...

Vertical integration followed by quantity competition is studied. In the first stage of the game downstream firms simultaneously decide whether to integrate with one of the upstream suppliers. If firms are not able to observe whether their vertically integrated competitor enters the...

The author presents a model of copyright law as a means to regulate entry into information markets. The model shows under what conditions copyright rules may lead to excessive or insufficient entry. The entry conditions are used to assess the efficacy of copyright rules in maximizing the sum of...

The existing literature on "two-sided markets" addresses participation externalities, but so far it has neglected pecuniary externalities between competing platforms. In this paper we build a model that incorporates both externalities. In our setup differentiated platforms compete in advertising...

We propose an integrated method based on a two-sector small open economy dynamic and stochastic general equilibrium model to estimate non-tariff barriers and quantify the impact of services liberalization. The major component of trade barriers is explicitly modeled through the introduction of...

Canada has enjoyed high growth while adjusting smoothly to commodity price gains, currency appreciation, and, more recently, slowing U.S. demand. Monetary policy has appropriately shifted to guarding against increasing near-term downside risks. A sound fiscal framework policy has produced an...

Cet article analyse un jeu simple à deux périodes dans lequel deux producteurs fabriquant un bien homogène se font concurrence pour fournir un distributeur. Les auteurs montrent que si les producteurs sont vulnérables (c’est-à-dire s’ils sont exclus du marché en cas d’une commande...

Stimulating entrepreneurship is high on the policy agenda of many countries. We study the effects of tax policies on entrepreneurs’ choice of riskiness (quality) of an innovation project, and on their mode of commercializing the innovation (market entry versus sale). Limited loss offset...

This paper explores the relationship between the intensity of competition in product markets and firms' incentives to lower their production costs by illegal means. Our framework combines a Salop circle with a crime model à la Becker, allowing us to differentiate between several measures for...
