In a general equilibrium model with a continuum of traders and bounded aggregate endowment, I investigate the Market Selection Hypothesis that markets favor traders with accurate beliefs. Contrary to known results for economies with (only) finitely many traders, I find that risk attitudes affect...

Even the most rudimentary training from Economics 101 starts with demand curves going down and supply curves going up. They are so 'natural' that they sound even more obvious than the Euclidian postulates in mathematics. But are they? What do they actually mean? Start with "demand curves". Are...

We provide necessary conditions for Pareto optimum in economies where tastes or technologies may be nonconvex, nonsmooth, and affected by externalities. Firms can pursue own objectives, much like the consumers. Infinite-dimensional commodity spaces are accommodated. Public goods and material...

Son yıllarda iktisat yazınında disiplinler arası çalışmaların sayısı giderek artmaktadır. Bu ilginin altında, doğrusal ve statik modellere dayanan klasik iktisat teorisinin modellerinin, gerçekte kompleks/karmaşık özellik gösteren yapıları çözümlemede yetersiz kalması...

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.

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...

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...

This paper analyses the effects of a carbon tax on a small open petroleum producing economy, using an aggregate intertemporal general equilibrium model with differentiated products. The long run effects on welfare and capital accumulation of both a unilateral and an international carbon tax are...

This paper analyses the effects of so-called "green" tax reforms on a small, open economy producing an imperfect substitute for foreign goods, using an intertemporal general equilibrium model. The labour market is characterised by union wage setting, and a fixed exchange rate implies wage...

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...
