This paper investigates the role of fiat money in decentralized markets, where producers have private information about the quality of the goods they supply. Money is divisible, terms of trade are determined endogenously, and agents can finance their consumption with money or with real...

This paper proposes a tractable New Keynesian (NK) economy with endogenous adjustment in product quality that nests the canonical framework. Endogenous quality choice reduces the slope of the traditional NK Phillips curve and ampliffes the economy's response to productivity shocks. This leads to...

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...

We study the optimal combination of conventional (interest rates) and unconventional (credit easing) monetary policy in a model where agency costs generate a spread between deposit and lending rates. We show that unconventional measures can be a powerful substitute for interest rate policy in...

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'...
