This paper considers the economic and political drivers of sovereign default, focusing on countries rich enough to render sovereign default a ‘won’t pay’ rather than a ‘can’t pay’ phenomenon. Unlike many private contracts, sovereign debt contracts rely almost exclusively on...

In this Paper, we analyse the implications of price setting restrictions for the conduct of cyclical fiscal and monetary policy. We consider an environment with monopolistic competitive firms, a shopping time technology, prices set one period in advance, and government expenditures that must be...

How should monetary and fiscal policy react to adverse financial shocks? If monetary policy is constrained by the zero lower bound on the nominal interest rate, subsidising the interest rate on loans is the optimal policy. The subsidies can mimic movements in the interest rate and can therefore...

We consider standard cash-in-advance monetary models and show that there are interest rate or money supply rules such that equilibria are unique. The existence of these single instrument rules depends on whether the economy has an infinite horizon or an arbitrarily large but finite horizon.

When the zero lower bound on nominal interest rates binds, monetary policy cannot provide appropriate stimulus. We show that in the standard New Keynesian model, tax policy can deliver such stimulus at no cost and in a time-consistent manner. There is no need to use inefficient policies such as...

The roles of central banks in the advanced economies have expanded and multiplied since the beginning of the crisis. The conventional monetary policy roles - setting interest rates in the pursuit of macroeconomic stability and acting as lender of last resort and market maker of last resort to...

Building on Calvo (1988), we develop a stochastic monetary economy in which government default may be driven by either self-fulfilling expectations or weak fundamentals, and explore conditions under which central banks can rule out the former. We analyze monetary backstops resting on the ability...

Central banks’ economic and political importance has grown in advanced economies since the start of the Great Financial Crisis in 2007. An unwillingness or inability of governments to use countercyclical fiscal policy has made monetary policy the only stabilization tool in town. However, much...

This Paper analyses the occurrence of non-Keynesian effects in fiscal consolidations in the EU. The analysis is carried out both ex post, i.e. by looking at the emergence of expansionary consolidations in the past and at their characteristics, and ex ante, i.e. by simulating with the European...

This Paper derives the optimal composition of the Brazilian public debt by looking at the relative impact of the risk and cost of alternative debt instruments on the probability of missing the stabilization target. This allows to price risk against the expected cost of debt service and thus to...
