Im Rahmen der Performancemessung werden häufig attraktive Risiko-Rendite-Eigenschaften von Hedgefonds hervorgehoben. Wir zeigen jedoch, dass diese Aussagenauf sehr instabile Schätzungen der Inputparameter aufbauen, denn je nachdem,welcher Zeitraum oder welche Marktphase betrachtet wird,...

We investigate the use of performance appraisal (PA) in German Firms. First, we derivehypotheses on individual and job based determinants of PA usage. Based on arepresentative German data set on individual employees, we test these hypotheses and alsoexplore the impact of PA on performance pay...

Based on a sample of 7,378 firms going public in the 1975-2005 period, we document a significant underperformance of IPO firms over the first year after going public, while there is virtually no underperformance thereafter. Moreover, by decomposing the Carhart-alpha we find that IPO...

We present a regression-based generalization of the calendar time portfolio approach which allows for decomposing the risk-adjusted performance of private investors (or firms or mutual funds) into multivariate and continuous subject characteristics. Our technique remedies several well-known...

The measurement of company performance poses several challenges. Three critical ones are: balancing short-term and long-term performance, the need to use multiple measures to capture the broad meaning of performance, and finding the right peer comparators. We argue that truly sustainable long...

After a short review on the history of human capital measurement we describe anddiscuss different approaches that are in use to assess the intangible assetts of anorganisation based on knowledge and behaviour. While deductive indicators helpto rise the questions on the value of intangible...

Based on a new methodological framework we investigate IPO (under-)performance in asample of 7,378 firms going public in the 1975-2005 period. We explicitly vary the time horizonin our analysis and document a significant underperformance of IPO firms over the firstyear after going public, while...

Neben den klassischen Performancemaßen, wie der Sharpe-Ratio, der Treynor-Ratio und dem Jensen-Alpha wurden in den letzten Jahrzehnten weiterführende Ansätze für die Analyse und Bewertung vonKapitalanlagen entwickelt. Die moderneren Performancemaße verlangen keine Konstanz derRisikomaße...

The question of whether or not mergers and acquisitions have helped to enhancebanks’ efficiency and profitability has not yet been conclusively resolved in theliterature. We argue that this is partly due to the severe methodological problemsinvolved. In this study, we analyze the effect of...
