We study the market price of risk, the stock volatility and the hedging behavior in equilibrium of heterogeneous agents with arbitrary utility functions, consuming only at the end of the time horizon, and with the state variable following an arbitrary homogeneous diffusion process. We introduce...

Empirical studies on credit spread determinants are predicated on the presence of a single-regime over the entire sample period and thus find limited explanatory power. We show that a single regime model hides the fact that the explanatory variables take on different loadings across changing...

This paper explores Affine, Quadratic and Hybrid Term Structure Models in discrete time. Hybrid specification joints ATSM and QTSM with correlated Gaussian state variables. We provide new formulae and a new estimation strategy that make these models implementable. We estimate and extract latent...

In this paper, we focus on the pricing of a particular life insurance contract where the conditional payoff to the policyholder is the maximum of two risky assets. The first one has larger expected returns but is riskier while the second one is less risky but still can earn more than an...

Between 1999 and 2007, WR Hambrecht completed 19 IPOs in the U.S. using an auction mechanism. We analyze investor behavior and mechanism performance in these auctioned IPOs using detailed bidding data. The existence of some bids posted at high prices suggests that some investors (mostly retail)...

This paper argues that financial links between agents may lead to the resilience or to the contagion of financial distress. Our model details the real effects of agents' beliefs on the resilience of the economy. When the economy is connected enough, it is subject to an unstable equilibrium. Our...

Using a sample of unscheduled stock options granted to CEOs of large Canadian firms, we find reliable evidence of option grants manipulation. Our results show that the introduction of the two-day filing requirement following the Sarbanes-Oxley Act (SOX) has eliminated backdating practice by...

This paper studies the relation between momentum trading and information. We present a variety of evidence supporting the hypothesis that momentum trading is linked to a lack of information. Firstly, using foreign portfolio flows in individual stocks we document significant momentum trading...

Recent academic studies indicate that acquirers' cumulative abnormal returns (CAR) decline from deal to deal in acquisitions programs. Does this pattern suggest hubristic CEO behaviors are significant enough to influence average CAR patterns during acquisitions programs? An alternative...

The estimation of expected security returns is one of the major tasks for the practical implementation of the Markowitz optimization. Against this background, in 1992 Black and Litterman developed an approach based on (theoretical established) expected equilibrium returns which also accounts for...
