Price-matching guarantees (PMGs) are offered in a wide array of product categories in retail markets. PMGs offer consumers the assurance that, should they find a lower price elsewhere within a specified period after purchase, the retailer will match that price and refund the price difference....

The price discrimination literature typically makes the assumption of no consumer arbitrage. This assumption is increasingly violated in the digital economy, where coupons are traded with increased frequency online. In this paper, we analyze the welfare impacts of coupon trading using a modified...

We study price formation in the standard model of consumer search for differentiated products but allow for search cost heterogeneity. In doing so, we dispense with the usual assumption that all consumers search at least once in equilibrium. This allows us to analyze the manner in which prices...

This study constructs a consumer search model in which some consumers search for multiple products, whereas others search for a single product. A price difference arises because of a difference in the price elasticity for each group. We show that a positive demand shock to one of the products...

In some markets, consumers do not know the attributes of all the products that are available in the market, or the prices at which they are offered. To reduce this uncertainty consumers may, at a cost, gather and process information about the attributes and prices of the different products. The...

This paper provides useful implications for managers and marketing practitioners using data on consumers' purchase history for price discrimination purposes. It is also useful for competition policy agencies and consumer advocates. It highlights that the shape of preferences plays an important...

We consider a duopolistic market in which a green firm competes with a brown rival and both firms offer two vertically differentiated quality products. We study optimal non-linear contracts offered by the two firms when consumers: (i) are privately informed about their willingness to pay for...

This survey aims to provide an overview of recent developments in the industrial organization literature that explores the behavior of profit-maximizing firms facing consumers with reference-dependent preferences and loss aversion. We discuss the implications of loss aversion on the practice of...

We study price formation in the standard model of consumer search for differentiated products but allow for search cost heterogeneity. In doing so, we dispense with the usual assumption that all consumers search at least once in equilibrium. This allows us to analyze the manner in which prices...

We consider a simple two period model where consumers have different switching costs. Before the market opens, there was an incumbent who sold to all consumers. We identify the equilibrium both with Stackelberg and Bertrand competition and show how the presence of low switching cost consumers...
