Switching costs and network effects bind customers to vendors if products are incompatible, locking customers or even markets in to early choices. Lock-in hinders customers from changing suppliers in response to (predictable or unpredictable) changes in efficiency, and gives vendors lucrative ex...

We argue that at the level of the national economy, an import quota transforms national welfare in the form of government revenues and consumer surplus into producer surplus to the domestic monopolist protected by the quota. An import quota confers substantial market power to the local...

For many goods (such as experience goods or addictive goods), consumers' preferences may change over time. In this paper, we examine a monopolist's optimal pricing schedule when current consumption can affect a consumer's valuation in the future and valuations are unobservable. We assume that...

We investigate the robustness of the new foreclosure doctrine and its associated welfare implications to the introduction of incomplete information. In particular, we let the upstream firm’s marginal cost be private information, unknown to the downstream firms. The previous literature has...

An exhaustive comparative statics analysis of a model of a monopolistic firm facing price-cap regulation and a variety of commonly implemented command-and-control environmental regulations is carried out. The comparative statics are intrinsic to each of the models and thus form their basic,...

We analyze the welfare consequences of a monopolist having additional information about consumers' tastes, beyond the prior distribution; the additional information can be used to charge different prices to different segments of the market, i.e., carry out "third degree price discrimination." We...

Professional sports teams receive large subsidies, some in excess of $500 million, from local governments for the construction of new facilities. These subsidies cannot be explained by tangible economic benefits, and estimates of the value of intangible benefits also fall short of typical...

We estimate a spatial model of liquor demand to analyze the impact of government-controlled retailing on entry patterns. In the absence of the Pennsylvania Liquor Control Board, the state would have roughly 2.5 times the current number of stores, higher consumer surplus, and lower payments to...
