Using an empirical framework derived from models of nonlinear pricing, we estimate the degree of quality degradation in cable television markets. We find lower bounds on quality degradation ranging from 11% to 45% of observed service qualities. Furthermore, cable operators in markets with local...

We measure the welfare consequences of endogenous quality choice in imperfectly competitive markets. We introduce the concept of a "quality markup" and measure the relative welfare consequences of market power over price and quality. For U.S. paid-television markets during 1997-2006, we find...

Exploiting a rich panel data set on anti-ulcer drug prescriptions, we measure the effects of uncertainty and learning in the demand for pharmaceutical drugs. We estimate a dynamic matching model of demand under uncertainty in which patients learn from prescription experience about the...

We measure the welfare consequences of endogenous quality choice in imperfectly competitive markets. We introduce the concept of a "quality markup" and measure the relative welfare consequences of market power over price and quality. For U.S. paid-television markets during 1997-2006, we find...

We measure the welfare consequences of endogenous quality choice in imperfectly competitive markets. We introduce the concept of a "quality markup" and measure the relative importance for welfare of market power over price versus market power over quality. For U.S. cable-television markets...

We measure the welfare distortions from endogenous quality choice in imperfectly competitive markets. For U.S. cable-television markets between 1997-2006, prices are 33% to 74% higher and qualities 23% to 55% higher than socially optimal. Such quality overprovision contradicts classic results in...

Due to differences in the effectiveness and side effects of different drugs, uncertainty is an important component of prescription drug choice. This uncertainty can cause patients and doctors to experiment with different drugs until they find a good match. In this paper, we specify and estimate...

Using an empirical framework based on the Mussa-Rosen model of monopoly quality choice, we calculate the degree of quality degradation in cable television markets and the impact of regulation on those choices. We find lower bounds of quality degradation ranging from 11 to 45% of offered service...
