We consider a simple continuous-time economy, populated by a largenumber of agents, more risk averse than the log agent, with heterogeneousrisk aversion densely covering an interval. Even though thedividend is a geometric Brownian motion, the equilibrium investmentopportunity set is stochastic...

In all the existing literature on survival in heterogeneous economies,the rate at which an agent vanishes in the long run relative to anotheragent can be characterized by the difference of the so-called survivalindices, where each survival index only depends on the preferencesof the...

We study the exponential utility indierence value h for a contingentclaim H in an incomplete market driven by two Brownian motions.The claim H depends on a nontradable asset variably correlated withthe traded asset available for hedging. We provide an explicit se-quence that converges to h,...

Consider the problem of testing s hypotheses simultaneously. In this paper, we derivemethods which control the generalized familywise error rate given by the probability ofk or more false rejections, abbreviated k-FWER. We derive both single-step and stepdownprocedures that control the k-FWER in...

Theoretical models predict that the value of a real option should be increasing in the volatility ofthe underlying asset. Thus, if real options are economically important, then firm values should bepositively related to volatility. Consistent with this prediction, we find evidence that stock...

This paper develops a tractable real options framework to analyze the eects of asym-metric information on investment and nancing decisions when rms require externalfunds to nance investment. Our analysis shows that corporate insiders can signal theirprivate information to outside investors using...

We consider a risky asset whose instantaneous rate of returntakes two dierent values and changes from one to the other one at randomtimes which are neither known, nor directly observable. We study the optimalallocation strategy of traders who, in the presence of cost of transactions, investin...

We propose an empirical approach to determine the various economic sourcesdriving the US yield curve. We allow the conditional dynamics of the yield at differ-ent maturities to change in reaction to past information coming from several relevantpredictor variables. We consider both endogenous,...

This paper suggests a factor model for carry trade strategies wherethe regression coeffcients are allowed to depend on market volatility and liquid-ity. Empirical results on daily data from 1995 to 2008 show that a typical carrytrade strategy has much higher exposure to the stock market and also...

The persistence of financial instability calls into question the adequacy of the current regulatory regime. Acritical review of the three pillars at the core of current financial regulation exposes some structural flaws.[...]
