Existing empirical evidence is inconclusive on whether professional investors show sophisticated behavior or not, a question which is at the heart of market efficiency. This ambiguous evidence is mostly based on trading data or laboratory evidence, which each has its limitations. We complement...

Our questionnaire survey finds that most fund managers rely on the strategies of buy-and-hold, momentum and contrarian trading. These strategies are typically applied mutually. Their use is rooted in the attributes and beliefs of the respective fund managers: buy-and-hold traders behave...

Empirical research has shown that inexperienced fund managers yield significantly higher returns than their more experienced colleagues. If the portfolios of inexperienced are not more risky, this result would contradict the hypothesis of market efficiency. Therefore, it is an important question...

Many public goods like dams, fire departments, and lighthouses do not provide direct utility but act more as insurance devices against floods, fire, and shipwreck. They either diminish the probability or the size of the loss. We extend the public good model with this insurance aspect and...

Experimental research on decision making under risk has until now always employed choice data in order to evaluate the empirical performance of expected utility and the alternative non-expected utility theories. The present paper performs a similar analysis which relies on pricing data instead...

One possible conclusion from recent experimental research on decision making under risk is that observed behaviour can be reasonable accommodated by expected utility plus an error term. This conclusion implies that the violation rate of expected utility should decrease if errors are excluded....

This study provides evidence from a questionnaire survey of fund managers. We find that the majority of respondents rely on momentum, contrarian and buy-&-hold strategies to some degree. Although there were few applicants who exclusively rely on a single trading strategy, clear preferences...
