We document the importance of the choice of error measure (percentage vs. logarithmic errors) for the comparison of alternative valuation procedures. We demonstrate for several multiple valuation methods (averaging with the arithmetic mean, harmonic mean, median, geometric mean) that the ranking...

We analyze the role of bankers on the boards of German non-financial companies for the period from 1994 to 2005. We find that banks that are represented on a firm's board promote their own business as lenders and as M&A advisors. They also seem to act as financial experts who help firms to...

"Between 1997 and 2004, Preussag, a diversified German conglomerate of "old economy" businesses, transformed itself into TUI, a company focused almost entirely on tourism and logistics. We analyze how Preussag executed this change, and how the change contributed to Preussag's underperformance in...

This paper analyzes optimal executive compensation contracts when managers are loss averse. We calibrate a stylized principal-agent model to the observed contracts of 595 CEOs and show that this model can explain observed option holdings and high base salaries remarkably well for a range of...

We analyze several proposals to restrict CEO compensation and calibrate two models of executive compensation that describe how firms would react to different types of restrictions. We find that many restrictions would have unintended consequences. Restrictions on total realized (ex-post) payouts...

We analyze the efficiency of indexing executive pay by calibrating the standard compensation model to a large sample of U.S. CEOs. The benefits from indexing the strike price of options are small, and fully indexing all options would increase compensation costs by 50% for most firms. Indexing...

We perform an experiment in which subjects bid for participating in a vote. The setting precludes conflicts of interests or direct benefits from voting. The theoretical value of participating in the vote is therefore zero if subjects have only instrumental reasons to vote and form correct...

We estimate a standard principal agent model with constant relative risk aversion and lognormal stock prices for a sample of 598 US CEOs. The model is widely used in the compensation literature, but it predicts that almost all of the CEOs in our sample should hold no stock options. Instead, CEOs...

We investigate biases of valuation methods and document that these depend largely on the choice of error measure (percentage vs. logarithmic errors) used to compare valuation procedures. We analyze four multiple valuation methods (averaging with the arithmetic mean, harmonic mean, median, and...

In the period 1997-2004, Preussag, a diversified German conglomerate of old economy businesses, changed itself into TUI, a company focused almost entirely on tourism and logistics. This paper analyzes how this strategy was executed and how it contributed to Preussag’s underperformance of the...
