Idiosyncratic Shocks and Aggregate Fluctuations in an Emerging Market
This paper provides the first assessment of the contribution of idiosyncratic shocks to aggregate fluctuations in an emerging market using confidential data on the universe of Chilean firms. We find that idiosyncratic shocks account for more than 40 percent of the volatility of aggregate sales. Although quite large, this contribution is smaller than documented in previous studies based on advanced economies, despite a higher degree of market concentration in Chile.We show that this finding is explained by larger firms being less volatile and by weaker propagation effects across Chilean firms.
Inflation Expectations and the Supply Chain
We show that firms rely on price changes observed along their supply chain to form expectations about aggregate inflation, and that these expectations have a complete pass-through to sales prices. Leveraging a unique dataset on Chilean firms merging expectation surveys and records from the VAT and customs registries, we document that changes in prices at which firms purchase inputs inform their forecasts of the economy’s inflation. This is the case even if changes in input costs do not determine the inflation outcome. These findings reject the full-information rational-expectations hypothesis and are consistent with firms’ disagreement about future inflation and inattention to macroeconomic news, which we document for Chile. Our results from a firm-level Phillips’ curve estimation suggest that firms’ beliefs about inflation are a key determinant for their price-setting decisions. Therefore, we argue that the channel we highlight in this paper has the potential to lead to dispersion in inflation expectations, price dispersion, and weaken the expectation channel of policies.
Global Economic Prospects, January 2024
Global Economic Prospects is a World Bank Group Flagship Report that examines global economic developments and prospects, with a special focus on emerging market and developing economies, on a semiannual basis (in January and June). Each edition includes analytical pieces on topical policy challenges faced by these economies.
Floating Exchange Rates at Fifty
Fifty years ago, in March 1973, the major industrial economies abandoned fixed exchange rates, conclusively ending the post–World War II Bretton Woods arrangements. Proponents believed their action would strengthen countries' ability to reconcile domestic macroeconomic policies with the balance of payments. But opponents feared it would initiate a new era of instability and financial shocks. Since 1973, much of the world has moved away from fixed exchange rates to a variety of regimes based on considerable exchange rate flexibility. But international trade conflicts and unstable capital flows, along with a rise in financial crises around the world, have nonetheless accompanied the global s...
Why Follow the Fed? Monetary Policy in Times of US Tightening
I conduct interviews with 32 Central Bankers from Emerging Markets and present five unifying themes that explain their behavior when reacting to a U.S. monetary tightening. I then estimate the impulse response functions of their two main monetary tools, the policy rate and foreign exchange interventions, to an increase in the U.S. rate, using the answers from the interviews as a guide for the best econometric specification. I find that most Central Banks react to a U.S. tightening by raising domestic rates, regardless of the exchange rate regime, but their reasons for doing so vary – from controlling inflation to preventing capital outflows.
Adjustment in Euro Area Deficit Countries
Imbalances within the euro area have been a defining feature of the crisis. This paper provides a critical analysis of the ongoing rebalancing of euro area “deficit economies” (Greece, Ireland, Portugal, and Spain) that accumulated large current account deficits and external liability positions in the run-up to the crisis. It shows that relative price adjustments have been proceeding gradually. Real effective exchange rates have depreciated by 10-25 percent, driven largely by reductions in unit labor costs due to labor shedding. While exports have typically rebounded, subdued demand accounts for much of the reduction in current account deficits. Hence, the current account balance of the ...
Monetary Policy Transmission Heterogeneity: Cross-Country Evidence
This paper revisits the transmission of monetary policy by constructing a novel dataset of monetary policy shocks for an unbalanced sample of 33 advanced and emerging market economies during the period 1991Q2-2023Q2. Our findings reveal that tightening monetary policy swiftly and negatively impacts economic activity, but the effects on inflation and inflation expectations takes time to fully materialize. Notably, there exist significant heterogeneities in the transmission of monetary policy across countries and time, depending on structural characteristics and cyclical conditions. Across countries, monetary policy is more effective in countries with flexible exchange rate regime, more developed financial systems, and credible monetary policy frameworks. In addition, we find that monetary policy transmission is stronger when uncertainty is low, financial conditions are tight and monetary policy is coordinated with fiscal policy—that is, when the stances move in the same direction.

Revisiting the Economic Case for Fiscal Union in the Euro Area
The paper makes an analytical contribution to the revived discussion about the euro area’s institutional setup. After significant progress during the euro crisis, the drive to complete Europe’s Economic and Monetary Union (EMU) had stalled, and the way forward will benefit from an in-depth look at the conceptual issues raised by the evolution and architecture of Europe, and the tradeoffs involved. A thorough look at the underlying economic issues suggests that in the long run, EMU will benefit from progressing along three mutually supporting tracks: introduce more fiscal risk sharing, helping to make the sovereign “no bailout” rule credible; complementary financial sector reforms to delink sovereigns and banks; and more effective rules to discourage moral hazard. This evolution would ensure that financial markets provide incentives for fiscal discipline. Introducing more fiscal union comes with myriad legal, technical, operational, and political problems, raising questions well beyond the remit of economics. But without decisive progress to foster fiscal risk sharing, EMU will continue to face existential risks.
International Macroeconomics
An essential introduction to one of the most timely and important subjects in economics International Macroeconomics presents a rigorous and theoretically elegant treatment of real-world international macroeconomic problems, incorporating the latest economic research while maintaining a microfounded, optimizing, and dynamic general equilibrium approach. This one-of-a-kind textbook introduces a basic model and applies it to fundamental questions in international economics, including the determinants of the current account in small and large economies, processes of adjustment to shocks, the determinants of the real exchange rate, the role of fixed and flexible exchange rates in models with nom...
