In this paper, I construct a model of an exchange economy in which bankruptcy arises in a manner similar to what we observe. This model is a more realistic representation of some markets in which intertemporal assets are traded. Using standard and natural assumptions, I show that every economy...

We study global properties of the equilibrium set of economies with a continuous consumption space. This framework is important in intertemporal allocation problems (continuous or infinite time), financial markets with uncertainty (continuous states of nature) and commodity differentiation. We...

We construct an index theorem for smooth infinite economies that shows that generically the number of equilibria is odd. As a corollary, this gives a new proof of existence and gives conditions that guarantee global uniqueness of equilibria. -- Uniqueness ; determinacy ; equilibria ; infinite...

The main contribution of this paper is to place smooth infinite economies in the setting of the equilibrium manifold and the natural projection map à la Balasko. We show that smooth infinite economies have an equilibrium set that has the structure of a Banach manifold and that the natural...

Exchange economies were created in which individuals faced losses. If people are risk seeking in the losses, as predicted by prospect theory, then due to the nonconvexity, the competitive equilibria are all on the boundaries of the Edgeworth Box. The experimental results are that risk-seeking...

Economic theory has generally akcnowledged the role that institutions have in shaping economic space. The distinction however between physical and institutional descriptions of economic activity has not received adequate attention within the mainstream paradigm. In this paper I show how a proper...
