We examine risk taking when the bank's preferences exhibit smooth ambiguity aversion. Ambiguity is modeled by a second-order probability distribution that captures the bank's uncertainty about which of the subjective beliefs govern the financial asset return risk. Ambiguity preferences are...

Das Entstehen und die Entwicklung von jungen Unternehmen wird maßgeblich durch Finanzierungsprobleme behindert. Inhalt des vorliegenden Arbeitspapiers ist die Auseinandersetzung mit einem möglichen Lösungsansatz dieser Probleme. Es wird aufgezeigt, welche Möglichkeiten jungen innovativen...

Der Mittelstand befürchtet durch die Neufassung der Baseler Eigenkapitalrichtlinien für Kreditinstitute Finanzierungsschwierigkeiten. Welche Bedeutung haben Bankkredite gegenwärtig bei der Finanzierung mittelständischer Unternehmen? Wird es als Folge von Basel II zu einer Kreditverknappung...

Following the seminal contribution of Kiyotaki and Moore (1997), the role of collateral constraints for business cycle fluctuations has been highlighted by several authors and collateralized debt is becoming a popular feature of business cycle models. In contrast, Kocherlakota (2000) and Cordoba...

Start-ups mostly have only limited internal financing. Post-entry performance should thus strongly depend on the availability of new external capital. In this study we analyze the impact of financial constraints on the performance of Swiss start-ups. Since we use cohort data, we have for some...

This paper analyzes the association between aggregate default and recovery rates on credit assets, and seeks to empirically explain this critical relationship. We examine recovery rates on corporate bond defaults, over the period 1982-2002.(...)

This paper analyzes the impact of various assumptions about the association between aggregate default probabilities and the loss given default on bank loans and corporate bonds, and seeks to empirically explain this critical relationship.(...)

We extend the definition of coherent risk measures, as introduced byArtzner, Delbaen, Eber and Heath, to general probability spaces and we show how to define such measures on the space of all random variables. We also give examples that relates the theory of coherent risk measures to game theory...

We study the problem of finding the minimal initial capital needed in order to hedge without risk a barrier option when the vector of proportions of wealth invested in each risky asset is constraint to lie in a closed convex domain...
