We generalize the classical concept of a certainty equivalent to a model where an investor can trade on a capital market with several future trading dates. We show that if a riskless asset is traded and the investor has a CARA utility then our generalized certainty equivalent can be evaluated...

We analyze a general business tax in an uncertain economy. Our tax system allows for a time-dependent tax rate and to this end we incorporate a generalized allowance for corporate equity (ACE). The generalized allowance is given by a fraction of the product of interest rate and book value of the...

This paper examines the learning dynamics of boundedly rational agents, who are asked to voluntarily contribute to a discrete public good. In an incomplete information setting, we discuss contribution games and subscription games, the latter including a money-back guarantee in case of provision...

Die Verbindung von Unternehmen ist keine Erscheinung der letzten Jahre. Vielmehr beruht das Konzept der Merger & Akquisition (M&A) auf grundlegenden wirtschaftstheoretischen Theorien, die in der Diskussion allerdings oftmals von populistischen Motiven für die Fusion im vorliegenden Fall...

Evolutionary dynamics in games imply de-facto spiteful behavior of the players: In order to 'survive' the evolutionary process, players must perform better than their opponents. This means they maximize relative rather than absolute payoffs. The paper shows that there is a class of games...

Will man den Einfluss der Einkommensteuer auf den Wert eines Projektes oder eines Unternehmens bestimmen, so bietet sich das Standardmodell als eines der populärsten Modelle an. Bei diesem Modell werden insbesondere im Nenner die Kapitalkosten um den Faktor 1 - gekürzt, wobei den Steuersatz...

This paper analyzes the impact of pollution and abatement policy within a stochastic endogenous growth model. The agents have environmental preferences, but they neglect their individual contribution to aggregate abatement. Therefore, environmental care is done by the government and financed via...

This paper extends the real interest differential (RID) model of Frankel (1979) by introducing Markov regime switches for three exchange rates over the years 1973 - 2000. Evidence of a non-linear relationship between exchange rates and underlying fundamentals is provided. One of the regimes...
