Technological change and deregulation have caused a major restructuring telecommunications equipment industry over the last two decades. Our empirical focus is on estimating the parameters of a production function for the equipment industry, and then using those estimates to analyze the...

We provide an asymptotic distribution theory for a class of Generalized Method of Moments estimators that arise in the study of differentiated product markets when the number of observations is associated with the number of products within a given market. We allow for three sources of error: the...

Empirical work on choice models, especially work on relatively new topics or data sets, often starts with descriptive, or what is often colloquially referred to as "reduced form", results. Our descriptive form formalizes this process. It is derived from the underlying behavioral model, has an...

Commercial health insurers in California use provider capitation payments to different extents. These are similar to arrangements introduced by the recent health reforms to give physicians incentives to control costs. In a previous paper we showed that patients whose insurers used capitation...

We develop a framework for the analysis of dynamic oligopolies with persistant sources of asymmetric information that enables applied analysis of situations of empirical importance that have been difficult to deal with. The framework generates policies that are "relatively" easy for agents to...

Due to increasing concern with climate change, producing energy from the wind has become an tool to substitute electric production away from fossil fuels. In the last decade, wind power capacity has grown tenfold, reaching 42% of newly installed electric capacity in 2008, yet accounts for less...

We estimate an insurer-specific preference function which rationalizes hospital referrals for privately-insured births in California. The function is additively separable in: a hospital price paid by the insurer, the distance traveled, and plan and severity-specific hospital fixed effects...
