The management of non-maturing account positions in a bank's balance like savings and sight deposits as well as certain types of variable-rate mortgages is complicated by the embedded options that its clients may exercise. In addition to the usual interest rate risk, uncertainty in the timing and amount of cash flows must be taken into account when investment or refinancing...

There is an extensive literature claiming that it is often di*cultnto make use of arbitrage opportunities in *nancial markets. Thisnpaper provides a new reason why existing arbitrage opportunitiesnmight not be seized. We consider a world with short-lived securities,nno short-selling constraints and no transaction costs. We show thatnto exploit all existing arbitrage opportunities,...

Social norms are usually neglected in economics, because they are to anlarge extent enforced through non-market interactions and difficult to isolatenempirically. In this paper, we offer a direct measure of the social norm to work andnwe show that this norm has important economic effects. The stronger the norm, thenmore quickly unemployed people find a new job. This behavior can be...

From a game theoretic point of view, fraudulent accounting to em-bellishnthe financial status of a firm and the use of drugs to enhancenperformance in sports are very similar. We study the replicator dy-namicsnof both applications within the same model. We allow for het-erogenousnpopulations, such as highly talented versus more mediocrenathletes, or high quality managers versus less...

Based on an experimental analysis of a simple monetary economy we argue that a monetarynsystem is more stable than one would expect from individual rationality. We show thatnpositive reciprocity stabilizes the monetary system, provided every participant considers thenfeedbacks of his choice to the stationary equilibrium. If however the participants do not playnstationary strategies...

Multistage stochastic programs with continuous underlying distributions involve the obstacle of high-dimensional integrals where the integrands' values again are given by solutions of stochastic programs. A common solution technique consists of discretizing the support of the original distributions leading to scenario trees and corresponding LPs which are ? up to a certain size...

Venture capitalists (VCs) not only finance but also add value to start-up companies. Advising firms is time consuming and creates a trade-off between intensity of advice and portfolio size. We jointly determine the optimal number of portfolio companies and the intensity of managerial advice. Diminishing returns to advice per firm call for a larger portfolio. With progressively...
