We provide explicit solutions for government spending multipliers during a liquidity trap and within a fixed exchange regime using standard closed and open-economy models. We confirm the potential for large multipliers during liquidity traps. For a currency union, we show that self-financed...

We characterize fiscal and monetary policy in a monetary union with the potential for rollover crises in sovereign debt markets. Member-country fiscal authorities lack commitment to repay their debt and choose fiscal policy independently. A common monetary authority chooses inflation for the...

The global economy has a chronic shortage of safe assets which lies behind many recent macroeconomic imbalances. This paper provides a simple model of the Safe Asset Mechanism (SAM), its recessionary safety traps, and its policy antidotes. Safety traps share many common features with...

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...

This case study compares the importance of prevailing market factors against that of COVID-19 dynamics and policy responses in explaining the evolution of Eurozone (EZ) sovereign spreads during the first half of 2020. Focusing on daily Eurozone CDS spreads, we adopt a multi-stage econometric...

We outline two divergent exit strategies of the U.S. from the post COVID-19 debt-overhang, and analyze their implications on Emerging Markets and global stability. The first strategy is the U.S. aiming at returning to the 2019, pre-COVID mode of loose fiscal policy and accommodating monetary...

This paper analyzes the macroeconomic effects of fiscal and labor market policies in a small open developing country. The basic framework considers an economy with a large informal production sector and a heterogeneous work force. The labor market is segmented as a result of efficiency...

This paper investigates the behavior of public debt in countries forming a union (as outlined, e.g., by the Maastricht treaty). We consider a federal union of states where the center has limited control over the spending patterns of the union members, and where the union members' behavior has...

When comparing marginal costs and benefits of a public project, most economists think in terms of adding together the marginal costs of production plus marginal costs of additional distortionary taxation. This paper clarifies how the "revenue effect" offsets the "distortionary effect." For...

We study cross-country risk sharing as a second-best problem for members of a currency union using an open economy model with nominal rigidities and provide two key results. First, we show that if financial markets are incomplete, the value of gaining access to any given level of aggregate risk...
