Consider the contracting problem of an input supplier dealing with several firms that compete in an output market. We show that, contrary to the key result of the previous literature, an input supplier's profit can increase with the number of downstream firms if the upstream firm is not a...

In this paper we consider symmetric aggregative games and investigate partial cooperation between a portion of the players that sign a cooperative agreement and the rest of the players. Existence results of partial cooperative equilibria are obtained when the players who do not sign the...

The standard Le Chatelier Principle states that the long-run demand for a good (in which by definition there are fewer restraints on the variables) is more elastic than short-run demand. The fundamental insight above goes well beyond demand theory, and proofs of this basic idea have been found...

In this note we analyse the effect of an increase in the amount of resources devoted to research within a general R&D growth model. We show that the initial effect of this increase is independent of whether the spill-over in R&D is linear or not. Even after two decades along a transitional...

We establish four necessary and sufficient conditions for the existence of the Averch-Johnson effect in a generalized version of their famous model of the rate-of-return regulated firm. The four necessary and sufficient conditions are then compared to the two stronger sufficient conditions for...

The conjecture of a price-induced technical progress was formulated by Hicks in 1932. It acquired prominence during the seventies with the work of Hayami and Ruttan who dealt with the agricultural sectors in the United States and Japan. A novel specification of this hypothesis is that output and...
