Protecting Lives and Livelihoods with Early and Tight Lockdowns
Description: Using high-frequency proxies for economic activity over a large sample of countries, we show that the economic crisis during the first seven months of the COVID-19 pandemic was only partly due to government lockdowns. Economic activity also contracted because of voluntary social distancing in response to higher infections. We also show that lockdowns can substantially reduce COVID-19 infections, especially if they are introduced early in a country's epidemic. Despite involving short-term economic costs, lockdowns may thus pave the way to a faster recovery by containing the spread of the virus and reducing voluntary social distancing. Finally, we document that lockdowns entail decreasing marginal economic costs but increasing marginal benefits in reducing infections. This suggests that tight short-lived lockdowns are preferable to mild prolonged measures.

COVID-19 Impact and Mitigation Policies: A Didactic Epidemiological-Macroeconomic Model Approach
Description: We develop an integrated epidemiological-macroeconomic model to analyze the interplay between the COVID-19 outbreak and economic activity, as a tool for capacity building purposes. We illustrate a workhorse framework that combines a rich epidemiological model with an economic block to shed light on the tradeoffs between saving lives and preserving economic outcomes under various mitigation policies and scenarios calibrated for emerging market and developing economies. In our benchmark setup, we link the effective contact frequency and labor supply decisions to the current state of the disease progression, allowing for relevant behavioral responses that introduce multiple feedback channels. We showcase the effects of various “smart” mitigation measures, e.g. improved quarantine capacity or targeted labor market restrictions, to alleviate the tradeoffs between health-related outcomes and economic activity, including in response to a second infection wave. The discovery of treatment or vaccine, and the possibility of temporary immunity for the recovered individuals are also considered. The model is further extended to a multisector framework to analyze the sectoral allocation effects of the COVID-19 shock.

Climate-Related Stress Testing: Transition Risks in Norway
Description: This paper explores three possible transmission channels for transition risk shocks to the financial system in Norway. First, we estimate the direct firm-level impact of a substantial increase in domestic carbon prices under severe assumptions. Second, we map the impact of a drastic increase in global carbon prices on the domestic economy via the Norwegian oil sector. Third, we model the impact of a forced reduction in Norwegian oil firms’ output on shareholder portfolios. Results show that such a sharp increase in carbon prices would have a significant but manageable impact on banks. Finally, the paper discusses ways to advance the still evolving field of transition risk stress testing.

An Apocalypse Foretold: Climate Shocks and Sovereign Defaults
Description: Climate change poses an existential threat to the global economy. While there is a growing body of literature on the economic consequences of climate change, research on the link between climate change and sovereign default risk is nonexistent. We aim to fill this gap in the literature by estimating the impact of climate change vulnerability and resilience on the probability of sovereign debt default. Using a sample of 116 countries over the period 1995–2017, we find that climate change vulnerability and resilience have significant effects on the probability of sovereign debt default, especially among low-income countries. That is, countries with greater vulnerability to climate change face a higher likelihood of debt default compared to more climate resilient countries. These findings remain robust to a battery of sensitivity checks, including alternative measures of sovereign debt default, model specifications, and estimation methodologies.

External Private Financing and Domestic Revenue Mobilization: A Dilemma?
Description: Domestic revenue mobilization (DRM) is essential for low-income and emerging economies to sustainably finance their development needs and has received increasing attention in recent years. Studies have centered on structural factors such as the size and the structure of the economy, and the quality of institutions, notably to account for weaknesses in revenue administrations. Nevertheless, DRM can take time and carry political costs. Raising more financing through donors or private investors may be an easier and more politically palatable way for countries to meet spending needs. Using an impact assessment methodology and panel regressions over a sample of 72 developing countries, we found no evidence that access to bond markets or external commercial loans undermines the countries’ efforts to collect tax revenue. On the contrary, we found that access to markets has a positive impact on domestic revenue mobilization. Plausible explanations are that private financing must be repaid, and strong macroeconomic fundamentals are key for maintaining market access. We have also found that macroeconomic stability and the strength of institutions do matter for domestic revenue mobilization.

Optimism Bias in Growth Forecasts—The Role of Planned Policy Adjustments
Description: Are IMF growth forecasts systematically optimistic? And if so, what is the role of planned policy adjustments on this outcome? Are program forecasts as biased as surveillance forecasts? We try to answer these questions using a comprehensive database on IMF forecasts of economic growth in surveillance and program cases during 2003–2017. We find that large planned fiscal and external adjustments are associated with optimistic growth projections, with significant non-linearities for both program and surveillance cases. Specifically, we find evidence that larger planned fiscal adjustment is associated with higher growth optimism in IMF non-concessional, non-precautionary financial arrangements. Our results show the tendency for optimism has persisted in the period after the Global Financial Crisis. Moreover, the strong correlation between the magnitude of the optimism and expected fiscal consolidation provides a cautionary signal for the post-COVID IMF projections as countries embark on a path of fiscal adjustment.

Crouching Beliefs, Hidden Biases: The Rise and Fall of Growth Narratives
Description: The debate among economists about an optimal growth recipe has been the subject of competing “narratives.” We identify four major growth narratives using the text analytics of IMF country reports over 1978-2019. The narrative “Economic Structure”—services, manufacturing, and agriculture—has been on a secular decline overshadowed by the “Structural Reforms”—competitiveness, transparency, and governance. We observe the rise and fall of the “Washington Consensus”—privatization and liberalization— and the rise to dominance of the “Washington Constellation,” a collection of many disparate terms such as productivity, tourism, and inequality. Growth theory concepts such as innovation, technology, and export policy have been marginal while industrial policy, which was once perceived positively, is making a comeback.

Twenty Years of Unconventional Monetary Policies: Lessons and Way Forward for the Bank of Japan
Description: The Bank of Japan has used unconventional monetary policies to fight deflation and stabilize the financial system since the late 1990s. While the Bank of Japan’s reflation efforts have evolved over time, inflation and inflation expectations have remained stubbornly low. This paper examines the evolution of monetary policy in Japan over the past twenty years, in order to draw relevant lessons and propose ways to strengthen the Bank of Japan’s policy framework. In doing so the analysis focuses on three aspects of monetary policy: objectives and goals; policy strategies; and the communication framework. Moreover, the paper discusses coordination between monetary, fiscal, and financial policies, and how the corresponding institutional design could be strengthened.

COVID-19 and the CPI: Is Inflation Underestimated?
Description: COVID-19 changed consumers’ spending patterns, making the CPI weights suddenly obsolete. In most regions, adjusting the CPI weights to account for the changes in spending patterns increases the estimate of inflation over the early months of the pandemic. Under-weighting of rising food prices and over-weighting of falling transport prices are the main causes of the underestimation of inflation. Updated CPI weights should be developed as soon as is feasible, but flux in spending patterns during the pandemic complicates the development as quickly as 2021 of weights that represent post-pandemic spending patterns.

Unveiling the Effects of Foreign Exchange Interventions: Evidence from the Kyrgyz Republic
Description: This paper analyzes determinants and consequences of FX interventions in the Kyrgyz Republic. Most of the literature on the topic focuses on advanced and emerging economies and this paper provides new evidence from a low-income country. We find that FX interventions take place in response to movements in the exchange rate and its volatility. There is also evidence of “leaning against the wind”, which is more pronounced for relatively larger FX sales and purchases. The “leaning against the wind” is asymmetric toward FX sales and largely reflects leaning against depreciation of domestic currency. We document a varying degree of de-facto exchange rate stability despite the de-jure floating exchange rate regime. During most of the sample, the exchange rate management index was relatively low in line with the floating exchange rate regime, with the exception of the period from 2018 Q4 until the COVID-19 shock, during which the exchange rate management index was relatively high.
