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...

We investigate the role of limited access to airport facilities as a determinant of the hub premium in the U.S. airline industry. We use original data from competition plans that airports are required to submit to the U.S. Department of Transportation in compliance with the Aviation Investment...

The federal government now confronts considerable political pressure to add CO2 to the existing set of criteria air pollutants. As with current criteria pollutants, proposals call for control of CO2, assuming that the control of each of the three criteria pollutants is separable from the others....

We study the effect of congestion on monopoly second-degree price discrimination. We provide three results. First, with congestion, the firm does not always provide distinct contracts (i.e., it is not always optimal to price discriminate) and it is more likely for the low-valuation buyer to be...

type="main" <p>We provide empirical evidence that multimarket contact facilitates tacit collusion among airlines using a flexible model of oligopolistic behavior, where conduct parameters are modelled as functions of multimarket contact. We find (i) carriers with little multimarket contact do not...</p>

Quality certification programs help consumers to identify high-quality products or sellers in markets with information asymmetries. Using data from eBay UK's online marketplace, we study how certification's impact on consumer demand varies with market- and seller-level attributes, exploiting...

To study whether consumers will pay more for products that generate charitable donations, we analyze data from eBay on charity and noncharity auctions of otherwise identical products. Charity prices are 6 percent higher, on average, than noncharity prices. Bids below the closing price are also...

The danger of alcohol- and drug-impaired driving implies that policies that reduce substance abuse can save lives. We study this issue in small U.S. counties where access to substance abuse treatment can be measured directly through the presence of treatment facilities. We find that placing an...

Relative to typical eBay auctions, bidding in eBay charity auctions occurs earlier and also less frequently in the auctions' final seconds. This suggests that some charity bidders benefit from driving-up others' payments, as when auction revenue is a public good.
