Models of consumer behavior play a key role in modern empirical Industrial Organization. In this paper, I survey some of the models used in this literature. In particular, I discuss two commonly used demand systems: multi-stage budgeting approaches and discrete choice models. I motivate their...

We characterize a firm's profit-maximizing turnover policy in an environment where managerial productivity changes stochastically over time and is the managers' private information. Our key positive result shows that the productivity level that the firm requires for retention declines with the...

In this paper, we construct a price index for broadband services in the United States between 2004 and 2009. We analyze over 1500 service contracts offered by DSL and cable providers in the United States. We employ a mix of matched-model methods and hedonic price index estimations to adjust for...

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...

This paper examines how career concerns can generate inefficiencies not only within firms but also in market outcomes. Career concerns may lead agents to avoid actions that, while value-increasing in expectation, could potentially be directly associated with a bad outcome. We apply this theory...

We estimate the effect of gasoline prices on short-run equilibrium prices and sales of new and used cars of different fuel economies. We find that gasoline prices have larger effects on the prices of used cars than of new cars, but that they have large effects on market shares and sales of new...
