This paper study the intertemporal consumption and investment problem in a continuous time setting when the secutity prices follow a Geometric Levy Process. Using stochastic calculus for semimartingals we obtain sufficient conditions for the existence of optimal consump- tion and investment...

This paper develops a general equilibrium model acknowledging that greater capital utilization requires either longer hours or unsocial schedules. Contrary to the popular depreciation-in-use models, capital utilization does not only concern the firms' organisational choices but also labor supply...

In this paper we are interested in inference based on heteroskedasticity consistent covariance matrix estimators, for which the appropriate bootstrap is a version of the wild bootstrap. Simulation results, obtained by a new very efficient method, show that all wild bootstrap tests exhibit...

We consider a homogenous good oligoply with identical consumers who learn about prices either by (sequentially) visiting firms or by consulting a price agency who sells information about which firm charges the lowest price. In the sequential equilibrium with maximal trade and minimal search,...
