This paper outlines a real options approach to valuing those announcements which are made by firms outside their legal requirements. From the firm's perspective, information is disclosed only if the manager of the firm is sufficiently certain that the market response to the announcement will...

This paper studies timing games in continuous time where payoffs are stochastic and strongly Markovian. The main interest is in characterizing equilibria where players preempt each other along almost every sample path. It is found that the existence of such preemption equilibria depends...

This paper studies a class of optimal stopping problems that has become popular in the area of investment under uncertainty (``real options''). Necessary conditions for solutions to these problems are that the solution dominates the payoff function and is superharmonic. Neither property is...

This paper analyses the temporary unemployment regulations that several governments of European countries have introduced during the recent recession. We view these measures as a collection of real options that governments provide to firms and value these options. We study, in particular, the...

This paper analyses the exercise decision of non-exclusive real options in a two-player setting. A general model of non-exclusive real options, allowing the underlying asset to follow any strong Markov process is developed, thus extending the existing literature, which is mainly based on...

Vector autoregressions (VAR's) are an important tool in time series analysis. However, relatively little is known about the finite-sample behaviour of parameter estimators. We address this issue here, by investigating maximum likelihood estimators (MLE's) in the context of a purely nonstationary...
