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...

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...

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...

The "leverage effect" refers to the well-established relationship between stock returns and both implied and realized volatility: volatility increases when the stock price falls. A standard explanation ties the phenomenon to the effect a change in market valuation of a firm's equity has on the...

This study examines how family firm characteristics affect capital structure decisions. In our analysis we disentangle the influence of three distinct components of a family firm: ownership, supervisory and management board activities by the founding family. Thereby, we use a unique panel...

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 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...

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...

Hedge funds are major players in the international financial system and nimble investment strategies including the use of leverage allow them to build up large positions. Yet the monitoring of systemic risks posed by the build-up of leverage is hampered by incomplete information on hedge funds'...

In a financial system where balance sheets are continuously marked to market, asset price changes show up immediately in changes in net worth, and elicit responses from financial intermediaries, who adjust the size of their balance sheets. We document evidence that marked to market leverage is...
