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...

A stumbling block in the modelling of competitive markets with commodity and price spaces of infinite dimensions, arises from having positive cones with an empty interior. This issue precludes the use of tools of differential analysis, ranging from the definition of a derivative, to the use of...

This paper shows that dynamic inefficiency can occur in dynamic general equilibrium models with fully optimizing, infinitely-lived households even in a situation with underinvestment. We identify necessary conditions for such a possibility and illustrate it in a standard R&D-based growth model....

This dissertation was written by Johannes Pfeiffer while he was working with the ifo Institute for Economic Research. It was completed in November 2016 and accepted as a doctoral thesis by the department of economics of the University Regensburg in December 2016. The thesis studies unintended...

The thesis studies unintended intertemporal reactions of fossil resource supply to climate policies, which often are subsumed under the notion of the green paradox, while taking into account the interrelationship between the resource and the capital market in a general equilibrium framework. Its...
