This paper applies models of price discrimination to the motion picture industry. Movies are durable goods with no resale market. Therefore, price discrimination using time can be used. The distributors release the movie in two different periods: theaters and video. The first is a high quality...

We provide a tractable characterization of the sharp identification region of the parameters θ in a broad class of incomplete econometric models. Models in this class have set-valued predictions that yield a convex set of conditional or unconditional moments for the model variables. In short,...

We propose inference procedures for partially identified population features for which the population identification region can be written as a transformation of the Aumann expectation of a properly defined set valued random variable (SVRV). An SVRV is a mapping that associates a set (rather...

We study identification in static, simultaneous move finite games of complete information, where the presence of multiple Nash equilibria may lead to partial identification of the model parameters. The identification regions for these parameters proposed in the related literature are known not...

The market structure of the telephone industry has been the focus of much empirical research following the divestiture of AT&T in 1984. Using data on Local Exchange Carriers (LECs), I estimate the total cost function of LECs operating between 1988 and 1995. First, I show that cost...

Economic theory often provides us with qualitative information on the properties of the functions in a model but rarely indicates their explicit functional form. Among these properties one can find monotonicity, concavity and supermodularity, which involve restricting the sign of the...
