Social Distancing, Vaccination and Evolution of COVID-19 Transmission Rates in Europe
This paper provides estimates of COVID-19 transmission rates and explains their evolution for selected European countries since the start of the pandemic taking account of changes in voluntary and government-mandated social distancing, incentives to comply, vaccination and the emergence of new variants. Evidence based on panel data modeling indicates that the diversity of outcomes that we document may have resulted from the non-linear interaction of mandated and voluntary social distancing and the economic incentives that governments provided to support isolation. The importance of these ...

Capital controls or exchange rate policy? a pecuniary externality perspective
In the aftermath of the global nancial crisis, a new policy paradigm has emerged> in which old-fashioned policies such as capital controls and other government distor-> tions have become part of the standard policy toolkit (the so-called macro-prudential> policies). On the wave of this seemingly unanimous policy consensus, a new strand> of theoretical literature contends that capital controls are welfare enhancing and can> be justi ed rigorously because of second-best considerations. Within the same the-> oretical framework adopted in this fast-growing literature, we show that a credible> ...

Optimal policy for macro-financial stability
In this paper we study whether policy makers should wait to intervene until a financial crisis strikes or rather act in a preemptive manner. We study this question in a relatively simple dynamic stochastic general equilibrium model in which crises are endogenous events induced by the presence of an occasionally binding borrowing constraint as in Mendoza (2010). First, we show that the same set of taxes that replicates the constrained social planner allocation could be used optimally by a Ramsey planner to achieve the first best unconstrained equilibrium: in both cases without any ...

Should Emerging Economies Embrace Quantitative Easing during the Pandemic?
Emerging economies are fighting COVID-19 and the economic sudden stop imposed by lockdown policies. Even before COVID-19 took root in emerging economies, however, investors had already started to flee these markets–to a much greater extent than they had at the onset of the 2008 global financial crisis (IMF, 2020; World Bank, 2020). Such sudden stops in capital flows can cause significant drops in economic activity, with recoveries that can take several years to complete (Benigno et al., 2020). Unfortunately, austerity and currency depreciations as enacted during the global financial crisis ...

The valuation channel of external adjustment
International financial integration has greatly increased the scope for changes in a country's net foreign asset position through the "valuation channel" of external adjustment, namely capital gains and losses on the country's external assets and liabilities. We examine this valuation channel theoretically in a dynamic equilibrium portfolio model with international trade in equity that encompasses complete and incomplete asset market scenarios. By separating asset prices and quantities in the definition of net foreign assets, we can characterize the first-order dynamics of both valuation ...

The domestic and global impact of Japan’s policies for growth
This paper illustrates the possible impact of fiscal adjustment and productivity-enhancing structural reforms on the Japanese and world economies. More specifically, using a five-bloc version of the IMF's Global Economy Model (GEM) featuring Japan, emerging Asia, the United States, the euro area and the rest of the world, the paper addresses the following two questions: What is the likely adjustment of key macroeconomic variables as Japan moves toward external equilibrium under alternative fiscal consolidation and total factor productivity growth scenarios? Do alternative policy scenarios in ...

Sudden Stops and COVID-19: Lessons from Mexico’s History
The COVID-19 pandemic produced a sharp contraction in capital flows in emerging markets during the spring of 2020. Such contractions are known as “sudden stops” and historically have been associated with significant downturns in a country’s economic activity. Evidence from Mexico’s financial crisis history suggests that sudden stops tend to exhibit a common pattern: the crisis lasts one to two years before a rapid but partial recovery, followed by years of protracted stagnation.

Estimating Macroeconomic Models of Financial Crises: An Endogenous Regime-Switching Approach
We estimate a workhorse dynamic stochastic general equilibrium (DSGE) model with an occasionally binding borrowing constraint. First, we propose a new specification of the occasionally binding constraint, where the transition between the unconstrained and constrained states is a stochastic function of the leverage level and the constraint multiplier. This specification maps into an endogenous regime-switching model. Second, we develop a general perturbation method for the solution of such a model. Third, we estimate the model with Bayesian methods to fit Mexico’s business cycle and ...

Social Distancing, Vaccination and Evolution of COVID-19 Transmission Rates in Europe
This paper provides estimates of COVID-19 effective reproduction numbers worldwide and explains their evolution for selected European countries since the start of the pandemic, taking account of changes in voluntary and government-mandated social distancing, incentives to comply, vaccination and the emergence of mutations. Evidence based on panel data modeling indicates that the diversity of outcomes that we document resulted from the non-linear interaction of mandated and voluntary social distancing and the economic incentives that governments provided to support isolation, with no one ...
