We incorporate product demonstrations into a game theoretic model of firm price competition. Demonstrations may include product samples, trials, return policies, reviews, or any other means by which a firm allows consumers to learn about their value for a new product. In our model,...

We consider an oligopolistic market where firms compete in price and quality and where consumers are heterogeneous in knowledge: some consumers know both the prices and quality of the products offered, some know only the prices and some know neither. We show that two types of signalling...

Hotelling’s famous Principle of Minimum Differentiation suggests that two firms engaging in spatial competition will decide to locate at the same place. Interpreting spatial competition as modeling product differentiation, firms will thus offer products that are not differentiated and equally...

We study the effects of improvements in market transparency on eBay on seller exit and continuing sellers' behavior. An improvement in market transparency by reducing strategic bias in buyer ratings led to a significant increase in buyer valuation especially of sellers rated poorly prior to the...

We study disclosure of information about the multidimensional state of the world when uninformed receivers' actions affect the sender's utility. Given a disclosure rule, the receivers form an expectation about the state following each message. Under the assumption that the sender's expected...

Hotelling’s famous ‘Principle of Minimum Differentiation’ asserts that two firms engaging in spatial competition with fixed prices will decide to locate at the same place. Interpreting spatial competition as modeling product differentiation, firms will thus offer products that are not...

We study the effects of improvements in market transparency on eBay on seller exit and continuing sellers' behavior. An improvement in market transparency by reducing strategic bias in buyer ratings led to a significant increase in buyer valuation especially of sellers rated poorly prior to the...

One striking development associated with the explosion of e-commerce is the increased transparency of sellers' quality history. In this paper we analyze how this affects firms' incentives to invest in quality when the outcome of investment is uncertain. We identify two conflicting effects. On...

We combine two extensions of the differentiated duopoly model of Dixit (1979), namely Caminal and Vives (1996) and Brander and Spencer (2015a,b), to analyze the effect of consumer learning on firms' incentives to differentiate their products in models of Cournot and Bertrand competition....

We estimate whether consumers respond to local energy costs when purchasing appliances. Using a dataset from an appliance retailer, we compare demand responsiveness to a measure of energy costs that varies with local energy prices versus purchase prices. We strongly reject that consumers are...
