In a two-country portfolio model with leverage constraints, I focus on private assets in order to understand how their behaviour can justify an expected excess return as well as the flight-to-safety observed in the data. The specific goal is to study how much these phenomena are explained by the...

I develop an open economy portfolio model to study how leveraged investors' wholesale funding affects the international transmission of shocks. Under binding borrowing limits, there is a link between the international investment positions of integrated economies as investors diversify the asset...

This study provides a rigorous empirical comparison of structural and reduced-formcredit risk frameworks. As major difference we focus on the discriminative modelingof the default time. In contrast to the previous literature, we calibrate both approaches to the same data set, apply comparable...

There has been a long debate about whether speculators are stabilizing or not.We consider a model where speculators have a stabilizing role in normal times,but may also provoke large risk panics. The very feature that makes arbitrageursliquidity providers in normal times, namely their tolerance...

We build a model of the financial sector to explain why adverse asset shocks in good economic timeslead to a sudden drying up of liquidity. Financial firms raise short-term debt in order to finance assetpurchases. When asset fundamentals worsen, debt induces firms to risk-shift; this limits...

This paper develops a dynamic trade-off model of optimal capital structure that takes intoaccount the fact that most firms have both invested assets and growth opportunities. Thesetwo sources of value react quite differently to business cycle risk. In particular, growth optionsare more sensitive...

We study a new class of three-factor affine option pricing models with interdependent volatilitydynamics and a stochastic skewness component unrelated to volatility shocks. Theseproperties are useful in order (i) to model a term structure of implied volatility skews moreconsistent with the data...

Die Erzielung eines positiven (statischen) Totalerfolgs ist die Voraussetzung fürdie steuerliche Wirksamkeit einer Investition. Diese fiskalische Einkünfteerzielungsabsicht decktsich jedoch nicht mit (dynamischen) betriebswirtschaftlichen Beurteilungskriterien, die ein Investorfür gewöhnlich...

Based on the APARCH model and two outlier detection methods, we computereliable time series of volatility asymmetry for 49 countries with relatively few ob-servations. Results show a steady increase in the asymmetry over the years for mostcountries. We nd that economic development and market...
