I review a subset of the empirical tools available for competition analysis. The tools discussed are those needed for the empirical analysis of; demand, production efficiency, product repositioning, and the evolution of market structure. Where relevant I start with a brief review of tools...

The US health care sector is large and growing - health care spending in 2011 amounted to $2.7 trillion and 18% of GDP. Approximately half of health care output is allocated via markets. In this paper, we analyze the industrial organization literature on health care markets focusing on the...

Do firm entry and exit play a major role in shaping aggregate dynamics? Our answer is yes. Entry and exit propagate the effects of aggregate shocks. In turn, this results in greater persistence and unconditional variation of aggregate time-series. These are features of the equilibrium allocation...

This paper studies the effects of marketing choice to firm growth. I assume that firm-level growth is the result of idiosyncratic productivity improvements with continuous arrival of new potential producers. A firm enters a market if it is profitable to incur the marginal cost to reach the first...

I survey the influence of Grossman and Hart's (1986) seminal paper in the field of International Trade. I discuss the implementation of the theory in open-economy environments and its implications for the international organization of production and the structure of international trade flows. I...

Based on an endogenous growth model, we show that intermediate goods markets imperfections can curb incentives to improve productivity downstream. We confirm such prediction by estimating a model of multifactor productivity growth in which the effects of upstream competition vary with distance...

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...

The field of Industrial Organization has made dramatic advances over the last few decades in developing empirical methods for analyzing imperfect competition and the organization of markets. We describe the motivation for these developments and some of the successes. We also discuss the relative...

Models dealing with cross-border acquisitions versus greenfield investment usually assume that the entry of a foreign firm into a market has effects on the outputs of all domestic firms in that market, but exit or entry of local firms is not considered. The purpose of this paper is to re-examine...
