This paper studies optimal interest-rate policies when the central bank operates a channel system of interest-rate control. We conduct our analysis in a dynamic general equilibrium model with infinitely-lived agents who are subject to idiosyncratic trading shocks which generate random liquidity...

In recent years, the learnability of rational expectations equilibria (REE) and determinacy of economic structures have rightfully joined the usual performance criteria among the sought-after goals of policy design. Some contributions to the literature, including Bullard and Mitra (2001) and...

This article complements the structural New-Keynesian macro framework with a no-arbitrage term structure model. Whereas our methodology is general, we focus on an extended macro-model with an unobservable time-varying markup and stochastic risk aversion. Term structure information helps to...

In this preliminary version we consider different types of ex-ante heterogeneity (production cost, preferences, market access, etc.) in a Lagos-Wright (2003) framework. Such heterogeneity generates equilibrium inequality in nominal wealth, or money holdings. We have two basic objectives. First,...

A defining feature of business cycles is the comovement of inputs at the sectorial level with aggregate activity. Standard models cannot account for this phenomenon. This paper develops and estimates a two-sector dynamic general equilibrium model which can account for this key regularity. My...

We consider an efficiency-wage model with the Calvo-type sticky prices and analyze optimal monetary policy when unemployment insurance is not perfect. With imperfect risk sharing, strict zero-inflation policy is no longer optimal even if the zero-inflation steady-state equilibrium is assumed to...
