This paper analyzes the relation between correlation risk and the cross-section of hedge fund returns.Legal framework and investment mandate imply that hedge funds can be severely exposed tocorrelation risk: Hedge funds ability to enter long-short positions can be useful to reduce marketbeta,...

This paper examines the role of bond ratings and the effects of rating-based regulations in thecorporate bond market. Exploiting an unanticipated mechanical change in how the benchmarkLehman bond indices are constructed in 2005, we show that rating-induced market segmentationof the bond market...

The well-known absence-of-arbitrage condition NFLVR from the fundamentaltheorem of asset pricing splits into two conditions, called NA and NUPBR.We give a literature overview of several equivalent reformulations of NUPBR;these include existence of a growth-optimal portfolio, existence of the...

This paper develops a model of corporate investment and financing decisions thatdiffers from previous contributions by recognizing that firms face uncertainty regardingtheir future access to credit markets and may have to search for creditors when raisingdebt financing. We show that accounting...

This paper studies the effects of investors’ heterogeneous beliefs on the trading volume,price volatility, and liquidity of stocks. Following Kurz and Motolese (2008), wepropose a simple theoretical model to show that the equilibrium stock price is linearlyand positively correlated with market...

This paper empirically investigates how the intensity of product market competitionaffects the cost of debt. Using a large sample of loans to publicly traded US manufac-turing fi…rms, I provide evidence that an intensi…fication of product market competitionamong fi…rms signifi…cantly...

We test whether the …´firms systematic equity risk reflects the shareholders´ incen-tives to default strategically on its debt. We use a standard real options model torelate the shareholders´strategic default behavior to frictions in the debt renegotia-tion procedure. We test its predictions...

This paper deals with asymptotically efficient estimation in exchangeable nonlinear dynamicpanel models with common unobservable factor. These models are especially relevantfor applications to large portfolios of credits, corporate bonds, or life insurance contracts, andare recommended in the...

The recursive prediction and filtering formulas of the Kalman filter are difficult to implementin nonlinear state space models. For Gaussian linear state space models, or for models with qualitativestate variables, the recursive formulas of the filter require the updating of a finite number...

Recent crises have seen very large spikes in asset price risk without dramatic shiftsin fundamentals. We propose an explanation for these risk panics based on selffullling shifts in risk made possible by a negative link between the current assetprice and risk about the future asset price. This...
