Abstract 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 obtain funding, especially in difficult times. We find little evidence that bankers monitor management and suggest that bankers on the board cause a decline in the valuations of non-financial firms. Banks’ equity ownership declined sharply during our sample period and the German financial system lost some of its formerly distinctive features.

ABSTRACT 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 parameterizations. We also derive and calibrate the general shape of the optimal contract that is increasing and convex for medium and high outcomes and that drops discontinuously to the lowest possible payout for low outcomes. Finally, we identify the critical features of the loss‐aversion model that render optimal contracts convex.
