An empirically well-established finding is that equity portfolios are concentrated in the domestic equity market of the investor. Previous theoretical and empirical analyses have mainly focused on institutional explanations and largely neglected individual behavior. In this study we report the...

When researchers from different fields with different norms collaborate, the question arises of how name-ordering conventions are chosen and how they affect contribution credits. In this paper, we answer these questions by studying two disciplines that exemplify the two cornerstones of...

By experimentally inducing risk aversion, overconfidence in an investment setting is investigated, comparing the evaluation of actual investment decisions with alternative choices. After selecting their own investment, subjects confront three alternative investment choices, including the optimal...

We study the impact of team decision making on market behavior and its consequences for subsequent individual performance in the Wason selection task, the single-most studied reasoning task. We reformulated the task in terms of ?assets? in a market context. Teams of traders learn the task?s...

A mechanism with low direct cost of use may be preferred to alternatives implementing more efficient allocations. We show this experimentally by giving pairs of subjects the option to agree on a single average price for a sequence of trades--in effect pooling several small bargains into a larger...

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...

This paper covers those parts of elementary logic that are needed in an introductory course on philosophy of science and the methodology of economics. With this aim in mind, much of the technical material from standard logic courses can be dropped. Specifically, the exposition emphasizes the...
