Empirically studying dynamic competition in oligopoly markets requires dealing with large states spaces and tackling difficult computational problems, while handling heterogeneity and multiple equilibria. In this paper, we discuss some of the ways recent work in Industrial Organization has dealt...

The ready-to-eat cereal industry is characterized by high concentration, high price-cost margins, large advertising to sales ratios, and numerous introductions of new products. Previous researchers have concluded that the ready-to-eat cereal industry is a classic example of an industry with...

This article analyzes generalized method of moments estimation when the sample is not a random draw from the population of interest. Auxiliary information, in the form of moments from the population of interest, is exploited to compute weights that are proportional to the inverse probability of...

We estimate a bargaining model of competition between hospitals and managed care organizations (MCOs) and use the estimates to evaluate the effects of hospital mergers. We find that MCO bargaining restrains hospital prices significantly. The model demonstrates the potential impact of coinsurance...

<Para ID="Par1">During 2013–2014, the Antitrust Division of the U.S. Department of Justice brought a wide range of matters to successful conclusions. The three matters that are discussed below demonstrate the diverse set of issues that the division examines every year. Copyright Springer Science+Business...</para>

This paper examines household consumption smoothing via variation in time spent shopping over the business cycle. Using scanner data on grocery purchases, we document how households lower the prices that they pay during downturns by increasing their coupon usage, sale purchasing, buying larger...

A good real estate agent might make up some of the commision he or she is paid by helping the seller get a more favorable outcome. We match several data sets to compare the outcomes obtained by sellers who listed their home on a For-Sale-By-Owner (FSBO) web site versus those who used an agent...

Food purchases differ substantially across countries. We use detailed household level data from the US, France and the UK to (i) document these differences; (ii) estimate a demand system for food and nutrients, and (iii) simulate counterfactual choices if households faced prices and nutritional...

Models of consumer behavior play a key role in modern empirical industrial organization. In this review, I survey some of the models used in this literature. In particular, I discuss two commonly used demand systems: multistage budgeting approaches and discrete choice models. I motivate their...
