The double-dividend argument (as used in political debates) addresses worries that a green tax may lead to higher unemployment when wages are inflexible. As protection against this possibility, it is proposed to use the proceeds of the green tax to subsidize employment. In the best case, this...

The paper proves that the Bayesian approach to learning and expectations formation implies no propositions that could conceivably be refuted by observation. For a (non-expanding) universe infinite in time but finite at any point of time, it is shown that by a suitable choice of priors, any...

Der Aufsatz befaßt sich mit der Frage, wie Theoreme der mathematischen Ökonomie getestet werden können und welche Rolle unrealistische Annahmen bei diesen Tests spielen. Als Beispiel dienen die bekannten Theoreme der neoklassischen Außenhandelstheorie, das Faktorpreisausgleichstheorem und...

It is often conjectured that participatory decision making may increase acceptance even of unfavorable decisions. The present paper tests this conjecture in a three-person power-to-take game. Two takers decide which fraction of the responder's endowment to transfer to themselves; the responder...

Using a simple OLG model where the research output of one generation provides inputs for the next, the paper explains how quality standards can become established in scientific competition. Researchers seek status, which they get if their results are used by the next generation. Quality is...

Players from two populations, predictors and predictees, are randomly matched in a game--theoretic version of Newcomb's Problem. Predictors are able to predict the predictees' choices by observing their type. There are two types of predictees, those who take their predictability into account by...

We analyze the employment effects of immigration within a model that accounts for several stylized facts of the German labor market. The co-existence of positive wage spans and unemployment is explained by wage rigidities that are simultaneously caused by effciency-wage setting and minimum...

In evolutionary models of indirect reciprocity, reputation mechanisms can stabilize cooperation even in severe cooperation problems like the prisoner's dilemma. Under certain circumstances, conditionally cooperative strategies ("cooperate iff your partner has a good reputation") cannot be...

Sugden (2000) offers an answer to the question of how unrealistic models can be used to explain real-world phenomena: by considering a set of unrealistic models, one may conclude that a result common to these models also holds for a realistic model that, however, is too complex to be analyzed,...
