The writing of contemporary history can be among the most treacherous of ambitions.
Everybody knows we never appreciate what we have till it's gone; that the owl of Minerva …

General Equilibrium Theory studies the properties and operation of free market economies.
The field is a response to a series of questions originally outlined by Leon Walras about the …

The overlapping expectations and the collective absence of arbitrage conditions introduced
in the economic literature to insure existence of Pareto optima and equilibria with short …

In finite markets with short-selling, conditions on agents' utilities insuring the existence of
efficient allocations and equilibria are by now well understood. In infinite markets, a standard …

The theory of existence of equilibrium with short-selling is reconsidered under risk and
ambiguity modelled by risk averse variational preferences. No-arbitrage conditions are …

In this paper, we first give a direct proof of the existence of Edgeworth equilibria for
exchange economies with consumption sets which are (possibly) unbounded below. The …

A new condition is introduced for the existence of equilibrium for an economy where
preferences need not be transitive or complete and the consumption set of each agent need …

We introduce differential information in the asset market model studied by Cheng J Math
Econ 20 (1): 137–152, 1991, Dana and Le Van J Math Econ 25 (3): 263–280, 1996 and Le …

We consider a model with an infinite number of states of nature, von Neumann–Morgenstern
utilities, where agents have different probability beliefs and where short sells are allowed …

The main contribution of the paper is to provide a weaker nonsatiation assumption than the
one commonly used in the literature to ensure the existence of competitive equilibrium. Our …
