Increasingly, retailers have access to better pricing technology, especially in online markets. Firms employ automated pricing algorithms that allow for high-frequency price changes. What are the implications for price competition? We develop a model of price competition where firms can differ...

The digital revolution of pricing enables retailers to change their prices more frequently than ever before. While the industry endorses this development, critics fear it could foster excessive price fluctuations. This paper studies price fluctuations in the context of brick-and-mortar retailing...

We examine the implications of different contractual forms for welfare as well as for firms’ profits in a framework in which a vertically integrated firm sells its good to an independent downstream firm. Under downstream Bertrand competition, the standard result of the desirability of two-part...

We provide a framework for empirical analysis of negotiated-price markets. Using mortgage market data and a search and negotiation model, we characterize the welfare impact of search frictions and quantify the role of search costs and brand loyalty for market power. Search frictions reduce...

We study how the interaction of market power and nominal price rigidity influences inflation dynamics. We formulate a tractable model of oligopolistic competition and sticky prices and derive closed-form expressions for the pass-through of idiosyncratic and common cost shocks to firms' prices....

We examine the profitability and welfare implications of price discrimination in a multi-dimensional model. First, when firms price discriminate on one and the same dimension, uniform price lies in between discriminatory prices and price discrimination raises profits relative to uniform pricing....

We investigate the welfare impacts of price discrimination using a two-dimensional product differentiation model with best-response asymmetry. Among our findings: (i) Price discrimination has a reduced demand elasticity effect in two-dimensional models but not in one-dimensional models. (ii)...

This paper investigates price patterns of off-patent pharmaceuticals in Sweden. I show that price dynamics are dependent on the number of competitors in the market. The price patterns follow predictions from a model of dynamic price competition in which the demand for pharmaceuticals...

We use experimental methods to demonstrate the anti-competitive potential of price matching guarantees in both symmetric and asymmetric cost duopolies. Our findings establish that when costs are symmetric, price-matching guarantees significantly increase market prices. In markets with cost...

This article studies dynamic pricing strategies in the Italian gasoline market before and after the market leader unilaterally announced its commitment to adopt a sticky-pricing policy. Using daily Italian firm level prices and weekly average EU prices, we show that the effect of the new policy...
