In a simple cash-credit model, I study the effects of the combination of costly tax collection and tax evasion on fiscal and monetary policy for optimal resource allocation. Allowing the informal sector to use cash more intensively than the formal sector, I compute the optimal interest and tax...

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'...

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...

How does economic activity outside of government control-informality-affect the conduct of fiscal and monetary policy? I study this question in a New Keynesian, small open economy model. The model is assumed to feature informality in both goods and labor markets. A non-traded sector produces a...

Can introducing Central Bank Digital Currency (CBDC) improve social welfare? We construct a dual currency model to study whether introducing CBDC with a recordkeeping technology can reduce tax evasion incentives in cash transactions, and further achieve a better allocation than in a cash-only...

We provide a general characterization of the structure of rational expectations equilibria of any degree of revelation for pure exchange, sequential economies, with deffinitely many states of private information, an incomplete financial market and nominal assets. We estimate the dimension of the...
