We investigate the effect of competition on price dispersion in the airline industry. Using panel data from 1993 to 2008, we find a non-monotonic effect of competition on price dispersion. An increase in competition is associated with greater price dispersion in concentrated markets but is...

Is there any evidence that innovation and technological progress are contained by competition and fostered by monopoly power? Our results based on a newly constructed dataset of US manufacturing industries observed over two decades suggest that this is not the case.On the contrary, using both...

Using data on four large mergers in the U.S. airline industry, we find consistent and significant effects of mergers on peripheral markets (i.e. those in which neither of the merging firms currently competes). Although such markets are rarely the focus of antitrust analysis, we demonstrate that...

By April 2013, the FCC's recent bill-shock agreement with cellular carriers requires consumers be notified when exceeding usage allowances. Will the agreement help or hurt consumers? To answer this question, we estimate a model of consumer plan choice, usage, and learning using a panel of...

In this paper we study the impact of competition on the provision of quality in the US airline industry. Using changes in competition triggered by LCC entry and airline mergers, we find that an increase in competition increases the provision of quality of major incumbent and non-merging airlines...

This paper develops and estimates a structural model of two-sided markets with durable platform intermediaries and affiliated products. It models buyers' purchase decisions of plat- forms and affiliated products and sellers' decisions of price-setting and entry, accounting for the dynamic...

In many industries, competition is far from perfect and managerial efficiency (or a fixed cost) varies among firms. However, traditional measurement of technological progress assumes perfect competition and no fixed cost. This paper incorporates these two factors in the technological-progress...
