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 percent of offered service qualities. Furthermore, cable operators in markets with local regulatory oversight offer signi...

“...capital account liberalization is...similar to the issue of how the human race should make use of fire. Fire warms our homes. It cooks our food, our internal combustion engines. It powers our automobiles and trucks and our turbojets. It powers our airplanes. No doubt, fire is very useful, and we are not going to give up its manifold benefits. On the other hand, fire can also burn you down a...

Successful motor performance requires the ability to adapt motor commands to task dynamics. A central question in movement neuroscience is how these dynamics are represented. Although it is widely assumed that dynamics (e.g., force fields) are represented in intrinsic, joint-based coordinates (Shadmehr R, Mussa-Ivaldi FA. J Neurosci 14: 3208-3224, 1994), recent evidence has questioned this prop...

Within the framework proposed by Mussa and Rosen (1978) for modelling quality differentiation, we allow consumers to buy simultaneously different variants of the same indivisible good. We call this the ”joint purchase option”. We show that this option dramatically affects price competition: while a unique equilibrium always prevails when consumers are assumed to make mutually exclusive purchase...

This paper examines competition in the postal sector when one private incumbent and one entrant play a three-stage game. First, firms choose their coverage. Then, they choose the quality of the mail. Finally, firms choose the price. I modify the traditional model of product differentiation proposed by Mussa and Rosen [Mussa, M., Rosen, S., 1978. Monopoly and product quality. Journal of Economic...

This paper extends the standard monopoly quality differentiation model by Mussa and Rosen (1978) to an environment where the production of a (qualitydifferentiated) product-line involves initial fixed investments in common assets such as production facilities or R&D. The fixed cost depends solely on the level of the highest quality, and the invested asset is shared among all the qualities in th...
