The question how an allocation decision is influenced by the investment horizon is of highest practical relevance, in particular in the context of retirement savings. Practitioners refer to the law of large numbers to argue that for a sufficiently long investment horizon it is almost certain to...

Previous studies have shown that individuals acquire an excessive amount of private information if the action space is small and discrete. In this experiment we use a continuous action space to investigate information acquisition. Participants sequentially assess their subjective probability...

Recently, researchers have gone a step further from just documenting biases of individual investors. More and more studies analyze how experience affects decisions and whether biases are eliminated by trading experience and learning. A necessary condition to learn is that investors actually know...

Anecdotal evidence and recent theoretical models argue that past stock returns affect subsequent stock trading volume. We study 3,000 individual investors over a 51 month period to test this prediction using linear panel regressions as well as negative binomial panel regressions and Logit panel...

Theoretical models predict that overconfident investors will trade more than rational investors. We directly test this hypothesis by correlating individual overconfidence scores with several measures of trading volume of individual investors (number of trades, turnover). Approximately 3000...

Between September 08 and June 09, a period with significant market events, we surveyed UK online-brokerage customers at 3-month intervals for their willingness to take risk, 3-month expectations of returns and risks for the market and their own portfolio, and self-reported risk attitude. This...

Die insbesondere während des vergangenen Jahrzehnts auf den Weg gebrachten Reformen unterstellen, dass private Haushalte immer stärker eigenständig Vorsorge gegen Unwägbarkeiten und Gefahren treffen. Das gilt mindestens in einem ergänzenden Sinne für die Altersvorsorge. Gleichzeitig fehlt...

In [21], Sethi et al. introduced a particular new-product adoption model. They determine optimal advertising and pricing policies of an associated deterministic infinite horizon discounted control problem. Their analysis is based on the fact that the corresponding Hamilton–Jacobi–Bellman...

The better-than-average effect describes the tendency of people to perceive their skills and virtues as being above average. We derive a new experimental paradigm to distinguish between two possible explanations for the effect, namely rational information processing and overconfidence....

Exploiting regional holidays in Germany as a source of exogenous cross-sectional variation in investor attention, we provide evidence that the well-known local bias at the individual level materially affects stock turnover at the firm level. Stocks of firms located in holiday regions are...
