Misperceiving the value of information in predicting the performance of others

Economic models typically allow for “free disposal” or “reversibility” of information, which implies non-negative value. Building on previous research on the “curse of knowledge” we explore situations where this might not be so. In three experiments, we document situations in which participants place positive value on information in attempting to predict the performance of uninformed...

In this paper we deal with two questions, (1) what are the origins of the current financial crisis, and (2) what did economists contribute, or why did economists fail to provide a convincing answer for the origins of the crisis, and possible solutions to overcome it? The economics profession apparently was unaware of the looming worldwide financial and economic crisis, and...

Deutscher M&A-Markt im Sog des globalen Abwärtstrends: Die M&A-Aktivitäten im ersten Halbjahr 2009

Jede Zeit, so sagt man, hat ihre Mode und ihre Musik. So wurden die Sechziger und Siebziger von der sog. Flower Power-Generation geprägt, die Achtziger und Neunziger standen im Zeichen von Disco, R&B, Pop und Rock. Analog lässt sich sagen: Jede Zeit hat ihr Geschäft mit Fusionen und Übernahmen. Diese Aussage spiegelt sich u.a. in der M&A-Wellentheorie wider, mit spezifischen...

Observed search behavior is more consistent with a new model that assumes dynamic updating of utility reference points than with models that are based on expected-utility maximization. Specifically, reference...

Academy of Management Review, 30, 180-191), different learning barriers are categorized and discussed with regard to...

The Role of Corporate Taxation in a Large Welfare State

In comparing the impact of corporate taxation and social insurance on foreign direct investment (FDI) and unemployment, the paper derives four main results: (i) the optimal size of the welfare state depends on the degree of risk-aversion, the unemployment rate and the excess burden of labor taxes. Unemployment partly reflects the country's exposure to globalization; (ii)...
