The decision to request a preliminary injunction-a court order that bans a party from certain behavior until its lawfulness is ascertained in a final court ruling at trial-is an important litigation instrument in many areas of the law including antitrust, copyright, patents, trademarks,...

We document that monetary policy inertia can help alleviate problems of indeterminacy and non-existence of stationary equilibrium observed for some commonly-studied monetary policy rules. We also find that inertia promotes learnability of equilibrium. The context is a simple, forward-looking...

We contrast a standard deterministic signaling game with one where the signal-generating mechanism is stochastic. With stochastic signals a unique equilibrium emerges that involves separation and has intuitive comparative-static properties as the degree of signaling depends on the prior type...
