We consider an oligopolistic market where firms compete in price and quality and where consumers have heterogeneous information: some consumers know both the prices, and quality of the products offered, some know only the prices, and some know neither. We show that if there are sufficiently many...

This paper proposes a theory of competition and customization. When firms allocate their production to both custom-made and standardized products, the fraction of sales from the former will increase in the face of increased competition. Recent surveys conducted by the World Bank on Chinese firms...

Motivated by the unprecedented availability of consumer information on the Internet, we characterize the winners and losers from potential privacy regulation in the context of four commonly-used oligopoly models: a linear city model, a circular city model, a vertical differentiation model, and a...

The presence of multiple sellers in the provision of (non-substitutable) complementary goods leads to outcomes that are worse than those generated by an integrated monopoly, a problem also known as the «tragedy of the anticommons». In this paper we identify some conditions under which the...

This paper investigates the relationship between the diffusion of EU standards and product quality upgrading using highly disaggregated import data to the EU in the food industry. Results show that, on average, the diffusion of EU voluntary standards boosts the rate of quality upgrading. However...

General Practitioners (GP) have limited means to compete. As quality is hard to observe by patients, GPs have incentives to signal quality by using instruments patients perceive as quality.

We uniquely examine the relationship between firm-sponsored training and product quality competition. Using an oligopolistic model of both price and quality competition, we show that an increase in the sensitivity of demand to product quality will strengthen firms’ incentives to train their...

The theory of voluntary disclosure of information posits that market forces lead senders to disclose information through a process of unravelling. This prediction requires that receivers hold correct beliefs and, in equilibrium, make adverse inferences about non-disclosed information. Previous...

We analyze firms' incentives to disclose deficiencies of their goods when consumers lack information. We distinguish two types of information: First, only some consumers are aware of the existence of deficiencies, which reduce the quality of the goods. Second, only some consumers have the...

We extend the theory of advertising as a quality signal, using a model where an entrant can choose to advertise by comparing its product to that of an established incumbent. Comparative advertising, comparing quality of one’s own product to that of a rival’s, empowers the latter to file for...
