We provide an econometric framework for estimating a game of simultaneous entry and pricing decisions while allowing for correlations between unobserved cost and demand shocks. We use our framework to account for selection in the pricing stage. We estimate the model using data from the US...

We introduce a model of oligopoly dynamic pricing where firms with limited capacity face a sales deadline. We establish conditions under which the equilibrium is unique and converges to a system of differential equations. Using unique and comprehensive pricing and bookings data for competing...

This paper addresses the effect of horizontal mergers on prices. It is shown that if firms compete in quantities and marginal costs are nondecreasing, any profitable merger failing to generate technological synergies must harm consumers through higher prices, irrespective of entry conditions in...

Supermarkets play a limited but increasingly important role in Latin-America groceries retail markets. Traditional grocery retailers still play a substantial role in most Latin American countries and the penetration of supermarkets is still behind the developed countries. Paradoxically, within...

The paper investigates early stage “modern” grocery retail adoption in an emerging market using primary household level panel data on grocery purchases in India's largest city, Mumbai. Specifically, we seek insight on which socioeconomic class is more likely to adopt, and why. We model...

We study the impact of targeted price controls on supermarket products in Argentina between 2007 and 2015. Using web-scraping methods, we collected daily prices for controlled and non-controlled goods and examined the differential effects of the policy on inflation, product availability, entry...

The countervailing power of large buyers subdues the market power of sellers, but price concessions won by large buyers in upstream markets may or may not translate into lower prices downstream. This paper presents a model in which upstream price concessions leads to lower downstream prices. In...

This paper investigates competition between chain-stores and independents in the UK opticians' industry, using the relationship between the number of outlets present in a local market and the market size. Chain-stores are shown to have a significant effect on local market competition. In...
