In Unternehmungen werden regelmäßig Entscheidungen über IT-Projekte getroffenmit dem Ziel, den Nutzen dieser Investitionen zu maximieren. Vor dem Hintergrund,dass rund zwei Drittel der IT-Projekte den prognostizierten Nutzen nicht erreichen,wird die Notwendigkeit einer ex ante Bewertung von...

This paper examines the impact of agency conicts on corporate nancing decisions. Werst build a dynamic contingent claims model in which nancing policy results from a trade-obetween tax benets, contracting frictions, and agency conicts. In our setting, partially-entrenched managers set the rms'...

We present the asymptotic properties of double-stage quantile regressionestimators with random regressors, where the first stage is based on quantile regressionswith the same quantile as in the second stage, which ensures robustness of the estimationprocedure. We derive invariance properties...

This paper shows that preferences alone cannot explain the patterns reported in the literature.

This paper proposes a novel methodology, based on the Common Principal Component analysis, allowing one to estimate the factors driving the term structure of interest rates, in the presence of time-varying covariance structure.

Many economic and econometric applications require the integration of functions lacking a closed form antiderivative, which is therefore a task that can only be solved by numerical methods. We propose a new family of probability densities that can be used as substitutes and have the property of...

In this study, we develop a technique for estimating a firm’s expected cost of equity capital derivedfrom analyst consensus forecasts and stock prices. Building on the work of Gebhardt/Lee/-Swaminathan (2001) and Easton/Taylor/Shroff/Sougiannis (2002), our approach allows dailyestimation, using...
