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...

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...
