We study markets for sensitive personal information. An agent wants to communicate with another party but any revealed information can be intercepted and sold to a third party whose reaction harms the agent. The market for information induces an adverse sorting effect, allocating the information...

This paper is, to our knowledge, the first paper in climate economics to consider the combination of spatial heat transport and polar amplification. We simplified the problem by stratifying the Earth into latitude belts and assuming, as in North et al. (1981), that the two hemispheres were...

Polar amplification is an established scientific fact which has been associated with the surface albedo feedback and to heat and moisture transport from the Equator to the Poles. In this paper we unify a two-box climate model, which allows for heat and moisture transport from the southern region...

There are many important decision problems where learning through experimentation is costly or impossible. In these situations, individuals may try to learn from observing the outcomes of others who have made similar decisions. Often, however, information about others comprises a selected...

Die empirische Überprüfung von steuerlich bedingten Marktsegmentationen (Steuer-Klientel- Effekten) ergab an den DM-Anleihemärkten asymmetrische Ergebnisse für Anleihen in Abhängigkeit von deren Kurshöhe. Im vorliegenden Beitrag werden diese Resultate durch Friktionen bei der Bildung von...

Der folgende Beitrag analysiert das optimale Verhalten eines Investors, der Arbitrage zwischen Kassa- und Futuresmarkt betreibt. Gegenüber dem Standardmodell der cash & carry-Arbitrage wird der zulässige Strategieraum des Arbitrageurs erweitert, indem berücksichtigt wird, daß der Arbitrageur...

Die asymmetrische Besteuerung von Zinseinkünften und Kursgewinnen kann zu Marktsegmentationen in Form von Steuer-Klientel-Effekten führen. Darunter ist der Tatbestand zu verstehen, daß es für PrivatanIeger mit hohem Grenzsteuersatz nicht sinnvoll ist, Anleihen mit hohem Kupon zu erwerben und...

Taking as given that we are consuming too much and that overconsumption leads to environmental degradation, the present paper examines the regulator's choices between informative advertisement and consumption taxation. We model overconsumption by considering individuals that care about social...
