We develop a continuous-time real options pricing model to study managers’incentives to cheat in the presence of equity …-based compensation policies.We show that managers’ incentives to cheat are strongly influenced by theefficiency of the justice. Our model …’s main result is that managers havegreater incentives to misreport with stock options than with common stocks.We finally …

In this article the problem of the American option valuation in a L´vy process setting is analyzed. The perpetual case is first considered. Without possible discontinuities (i.e. with negative jumps inthe call case), known results concerning the currency option value as well as the exercise...

We propose a simple class of semiparametric multivariate GARCH models, allowing for asymmetric volatilities and time-varying conditional correlations. Estimates for time-varying conditional correlations are constructed by means of a convex combination of estimates for averaged correlations...
