In a Lucas orchard with heterogeneous beliefs, we study the link between market-wide uncertainty, difference of opinionsand co-movement of stock returns. We show that this link plays an important role in explaining the dynamics of equilibriumvolatility and correlation risk premia. In our...

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,...

We introduce a new class of flexible and tractable matrix a±ne jump-diffusions (AJD) to modelmultivariate sources of financial risk. We first provide a complete transform analysis of this model class,which opens a range of new potential applications to, e.g., multivariate option pricing with...

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...

In the first three decades of CRSP data, value stocks have higher betas than growth stocks.Later on, the ranking is reversed and the gap in beta widens. What makes growth strategiesnowadays bear more market risk than value strategies? What are the causes of the reversalin the ranking of betas?...

We derive representations for the stock price drift and volatility in theequilibrium of agents with arbitrary, heterogeneous utility functionsand with the aggregate dividend following an arbitrary Markov diffusion.We introduce a new, intrinsic characteristic of the aggregate dividendprocess that...

A simple consumption-based two-period model is used to study the (theoretical)effects of disagreement on asset prices. Analytical and numerical results showthat individual uncertainty has a much larger effect on risk premia than disagreementif (i) the risk aversion is reasonably high and (ii)...

We study how the interaction of agents with different beliefs about a firm’s future cash flows determines the jointbehavior of credit spreads, option implied volatilities, and stock returns. Beliefs heterogeneity influences the pricing kernelin a way that supports more realistic credit spreads...
