This paper studies optimal monetary and fiscal policies in an economy à la Lucas and Stokey (1983) and Lagos and Wright (2005) with multiple cash and credit goods. We show that optimal policies are in general time inconsistent due to insufficient number of instruments to influence future...

This paper investigates the desirability of adopting a rule in favor of discretionary monetary policy in a model exhibiting Kydland and Prescott's dynamic inconsistency problem. We deviate from earlier work by adopting assumptions regarding policymaker preferences and inflation dynamics that are...

We investigate the desirability of adopting a rule in favor of discretionary monetary policy in a model exhibiting Kydland and Prescott's dynamic inconsistency problem but no fundamental incompatibility between the policymaker's price stability and full employment objectives. We show that if...

We consider an overlapping generation framework with search and private information to study optimal taxation. Agents sequentially trade in markets that are characterized by different frictions and trading protocols. In frictional decentralized markets, agents receive shocks that determine if...

Market distress can be the catalyst of a deleveraging wave, as in the 2007/08 financial crisis. This paper demonstrates how market distress and deleveraging can fuel each other in the presence of adverse selection problems in asset markets. At the core of the detrimental feedback loop is agents'...

This paper measures how the 2007-09 financial crisis affected the U.S. federal funds market. I accomplish this by developing and estimating a structural model of this market, in which intermediation plays a crucial role and borrowing banks differ in their unobserved probability of default. The...

We analyze fiscal rules within a Monetary Union in the presence of (i) asymmetric information on member states' potential output and (ii) bail-out among member states. The first-best deficit is contingent on the cycle, that is, on member states' output gap. In the presence of asymmetric...

We analyze fiscal rules within a Monetary Union in the presence of (i) asymmetric information about member states' potential output and, therefore, output gap and (ii) bail-out among member states. In our framework, bail-out lowers the scope for signalling (discrimination) by member states...

Although it is generally accepted that consumer confidence measures are informative signals about the state of the economy, theoretical macroeconomic models designed for the analysis of monetary policy typically do not provide a role for them. I develop a framework with asymmetric information in...
