Prevalent thinking about liquidity traps suggests that the perfect substitutability of money and bonds at a zero short-term nominal interest rate renders open-market operations ineffective for achieving macroeconomic stabilization goals. In an earlier paper, we showed that this reasoning does...

In this paper I focus on two specific hazard areas in the transition from Stage Two to Stage Three of European economic and monetary union (EMU), as well as on some key problems of Stage Three that EMU's monetary and fiscal structures appear ill-prepared to handle. The transitional hazards are...

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 studies optimal fiscal policy in an economy where heterogeneous agents with uncertain lifetimes coexist. We show that some plausible social welfare functions lead to time-inconsistent optimal plans, and we suggest restrictions on social preferences that avoid the problem. The...

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...

This paper studies the transmission of fiscal disturbances between countries, and the effect of those disturbances on worldwide capital intensity, in a context of growth. The model developed to address these issues allows for the production of both nontradable and relatively capital-intensive...
