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...

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...

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 paper contributes empirically to our understanding of informed traders. It analyzes traders' characteristics in an electronic limit order market via anonymous trader identities. We use six indicators of informed trading in a cross-sectional multivariate approach to identify traders with...

This paper analyzes the behaviour and motivation of fund managers in foreign exchange markets reflected in questionnaire evidence. We find that fund managers and FX dealers differ significantly. Fund managers rely more on fundamentals, basically due to their longer forecasting horizons, and...

The puzzling evidence of seemingly high momentum returns is related to an understanding of risk as a simple covariance. If we consider, however, risk in higher-order statistical moments, momentum returns appear less advantageous. Thus, a prospect-theoretical assessment of US stock momentum...
