Under certain conditions on the excess demand function, it is shown that the set of equilibrium prices coincides with the set of maximizers of a potential function. Therefore, monotone comparative statics techniques can be employed to study how equilibrium prices change when there are shocks to...

We revisit a classical theme of general equilibrium theory, namely the continuity of the Walras correspondence. Using a remarkable theorem due to Fort (1951) which has widely been used in recent literature on game theory, we are able to prove the generic continuity of the price equilibrium-set...

The transfer paradox describes the situation in which transfers of initial endowments within competitive market make the donor better off and (or) the recipient worse off. Advantageous redistribution, strong transfer paradox, and Chichilnisky paradox are the three cases of the transfer paradox...

This paper considers a multi-agent one-sector Ramsey equilibrium growth model with borrowing constraints. The extreme borrowing constraint used in the classical version of the model, surveyed in Becker (2006), and the limited form of borrowing constraint examined in Borissov and Dubey (2015) are...
