This paper studies the emergence of firm asymmetry as an equilibrium outcome. We consider differentiated Cournot and Bertrand duopolies where firms endogenously select their organizational governance and their timing strategy. For Cournot competition asymmetric and symmetric equilibria may...

The traditional concentration of basic research activities in academic settings, with applied research more prevalent in industrial settings, is a distinguishing feature of science and technology markets. This structure arises from a unique combination of product characteristics, and in turn it...

The association between the expansion of trade and conversion to Islam has been noted all over the world. In this paper the author integrates the data from Africa with a transaction cost argument that helps explain the economic logic behind this oft-noted association. The author also considers...

The world's predominantly Muslim countries have long been underdeveloped. This paper classifies, critiques, and extends the mechanisms that have been proposed as explanations for the pattern. One mechanism involves the use of Islam to legitimize worldviews that served vested interests. Another...

This paper formalizes the intuition that brands are consumed for image reasons and that advertising creates a brand's image. The key idea is that advertising informs the public of brand names and creates the possibility of conspicuous consumption by rendering brands a signalling device. In a...

A safe and risky seller serve a market. While the expensive safe seller can solve the problems of all consumers, the cheap risky seller can help a consumer only with a certain probability. The risky seller's success probabilities are distributed across consumers; by the choice of her quality the...

Homogeneous products are often sold by chains and locals but the chains charge higher prices. We explain this pricing pattern as well as the empirical fact that chains became increasingly dominant at the same time as consumer mobility increased: Consumers bear setup costs whenever they visit a...

It is well-known that a monopolist cannot commit to offer a high-quality contract to a consumer reading costs are positive. This paper shows that this also holds in a competitive environment with consumer heterogeneity if the contract space is unrestricted. If firms can offer standardized...

This paper studies profit-maximizing seller behavior when brand image affects demand. We consider a seller facing a population of consumers with heterogeneous tastes regarding product quality and brand image. First, we analyze active branding by the seller through costly advertising. Our...

This paper studies welfare consequences of consumer-side market transparency with endogenous entry of firms. Different from most studies, we consider the unique symmetric entry equilibrium, which is in mixed strategies. We identify two effects of market transparency on welfare: a competition...
