We use detailed data to estimate the private costs and private rents of United States patents for publicly-traded firms. In analyzing costs, we first introduce a novel theoretical model to interpret our estimates. We then combine lawsuit data from Derwent Litalert with non-practicing entity...

We formulate two empirical tests for collusive behavior based on the theoretical insights of Werden and Froeb [1994] and Athey, Bagwell, and Sanchirico [2004]. The first predicts that colluding firms will reduce pair-wise differences in prices within a market if demand satisfies certain...

This paper uses unique data on access to airport facilities to study the strategic entry, exit, and capacity decisions of firms in the US airline industry. I estimate a dynamic equilibrium model in which forward-looking firms invest in seating capacity and play a capacity-constrained pricing...

Airlines use robust scheduling to mitigate the impact of unforeseeable disruptions on profits. We examine how effectively three common practices – flexibility to swap aircraft, flexibility to reassign gates, and scheduled aircraft downtime – accomplish this goal. We first estimate a...

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