We present a set of necessary and sufficient conditions for a class of optimal control problems with pure state constraints for which the objective function is linear in the state variable but the objective function is only required to be upper semi-continuous in the control variable. We apply...

We consider how a benevolent regulator should regulate a polluting export industry when the industry, having private information about its abatement efficiency, has an option to move its operations abroad, with a type-dependent outside option rent. The paper focuses on the case where outside...

This paper analyzes the optimal choice of pricing schedules and technological deterrence levels in a market with digital piracy, when legal sellers can sometimes control the extent of piracy by implementing digital rights management (DRM) systems. It is shown that the seller's optimal pricing...
