Unlike the crisis years of 2007-2009 (when the insolvency of large banks was a major problem), the current round of the global financial crisis has fiscal origins. Almost all developed countries suffer from an excessive public debt burden that has been built up over the last two decades or more....

The euro crisis remains unresolved and the euro currency union incomplete and extraordinarily vulnerable. The euro regime's essential flaw and ultimate source of vulnerability is the decoupling of central bank and treasury institutions in the euro currency union. We propose a Euro Treasury...

This paper studies monetary and fiscal policy interactions in a two country model, where taxes on firms’ sales are optimally chosen and the monetary policy is set cooperatively. It turns out that in a two country setting non-cooperative fiscal policy makers have an incentive to change taxes on...

This paper combines a monetary structural vector-autoregression (SVAR) with a fiscal SVAR for Poland. Fiscal foresight, in the form of implementation lags, is accounted for with respect to both discretionary government spending and tax changes. We demonstrate the importance of combining monetary...

How does the need to preserve government debt sustainability affect the optimal monetary and fiscal policy response to a liquidity trap? To provide an answer, we employ a small stochastic New Keynesian model with a zero bound on nominal interest rates and characterize optimal time-consistent...

This paper proposes an equilibrium theory of nominal exchange rates, which offers a new perspective on various issues in open economy macroeconomics. The nominal exchange rate and portfolio choices are jointly determined in equilibrium, thus providing a new approach to overcoming the...

I develop and analyze a DSGE model of a currency union to revise the question of how to conduct monetary and fiscal policy in countries that share the same currency. In contrast with the previous literature which assumes coordination, this paper analyzes the case where coordination lacks among...

Does market incompleteness radically transform the properties of monetary economies? Using an analytically tractable heterogeneous agent New Keynesian (HANK) model, we show that whether incomplete markets resolve "policy paradoxes" in the representative agent New Keynesian model (RANK) depends...
