The video entertainment industry is experiencing increases in over-the-top (OTT) video usage and cord-cutting behavior. Using unique panel data from 2012–2016, we document the behavior of the 2.4% of households who “cut the cord” annually. After dropping TV, these households increase internet usage by 22%, reduce payments to multiple-system operators (MSOs) by 50%, and 16% acquire new OTT video subscriptions. These results indicate meaningful substitution between OTT video and TV and suggest that competition authorities should consider broadening market definitions. MSOs appear to have little incentive to degrade OTT video, despite OTT video's contribution to declining TV revenues.

We investigate the success of legislation aimed at increasing competition at highly concentrated U.S. airports, mainly by forcing these airports to increase the availability of scarce facilities. We use a multidimensional regression-discontinuity approach to exploit a sharp discontinuity in the law’s implementation and identify its effects. We find that fares decrease by 13.4% (20.2%) in markets with one (both) end point(s) covered. Approximately half of the decline is driven by the entry of low-cost carriers. We find little evidence that the fare declines were accompanied by a diminished quality of service, and passenger volumes increased, which suggests the legislation improved consumer welfare.
