This paper develops a structural macroeconometric model of the world economy, disaggregated into thirty five national economies. This panel unobserved components model features a monetary transmission mechanism, a fiscal transmission mechanism, and extensive macrofinancial linkages, both within...

The COVID-19 crisis is unique in many respects and, as the IMF (2021, p. 43) puts it: "a crisis like no other". A global economic contraction occurred that was unprecedented in its speed and depth. Support packages were put together in some parts of the world that also dwarfed anything seen up...

We provide a quantitative theory of deflation and secular stagnation. In our lifecycle framework, an aging population puts persistent downward pressure on the price level, real interest rates, and output. A novel feature of our theory is that it also recognizes the reactions of government...

We contribute to the growing empirical literature on monetary and fiscal interactions by applying a sign restriction identification scheme to a structural TVP-VAR in order to disentangle and evaluate the policy shocks and policy transmissions. This in turn allows us to study the Great Recession...

In this paper, we build a dynamic stochastic general-equilibrium model with housing and household debt, and compare the effectiveness of monetary policy, housing-related fiscal policy, and macroprudential regulations in reducing household indebtedness. The model features long-term fixed-rate...

The Flexible System of Global Models (FSGM) is a group of models developed by the Economic Modeling Division of the IMF for policy analysis. A typical module of FSGM is a multi-region, forward-looking semi-structural global model consisting of 24 regions. Using the three core modules focused on...

Climate change is one of the greatest challenges of this century. Mitigation requires a large-scale transition to a low-carbon economy. This paper provides an overview of the rapidly growing literature on the role of macroeconomic and financial policy tools in enabling this transition. The...

This study investigates the evolution of central bank profits as fiscal revenue (or: seigniorage) before and in the aftermath of the global financial crisis of 2008-9, focusing on a select group of central banks - namely the Bank of England, the United States Federal Reserve System, the Bank of...

Fiscal stimulus was widely advocated during the global crisis, a period characterized by monetary policy constrained by the effective lower bound (ELB) in many countries, in part because of expected positive spillovers. Standard New Keynesian models predict the cross-border transmission of...

Halving the US current account deficit as a share of GDP is likely to impose a burden of $2,350 per capita on the United States, which explains why US policymakers want to postpone adjustment. The rest of the world relies on the economic stimulus of a widening US external deficit, which explains...
