The Effectiveness of Job-Retention Schemes: COVID-19 Evidence From the German States
Description: Kurzarbeit (KA), Germany’s short-time work program, is widely credited with saving jobs and supporting domestic demand during the COVID-19 recession. We quantify the impact by exploiting state-level variation in exposure to the pandemic shock and KA take-up. We construct a shift-share measure of the labor demand shock and instrument KA take-up using the pre-existing, state-specific share of workers eligible for KA. We find, first, that KA was crucial in mitigating unemployment: absent its expansion the unemployment rate would have increased by an additional 3 pp on average at the trough of the recession. Second, KA also bolstered domestic demand: the contraction in consumption could have been 2 to 3 times larger absent the program. Finally, we provide preliminary evidence on the sensitivity of the medium-run reallocation of resources to the prevalence of jobretention schemes during the Global Financial Crisis.

Scaling up Climate Mitigation Policy in Germany
Description: Germany has set national greenhouse emissions targets of a 65 percent reduction below 1990 levels by 2030 and net zero emissions by 2045, along with various sectoral emissions goals. To achieve these targets, the government has introduced multi-pronged policy measures, including a national emissions trading system (ETS), which complements the ETS at the EU level. This paper shows the substantial variation in the price responsiveness of emissions across sectors and thus prices implied by sectoral targets. It proposes the following measures to help Germany meet emissions targets with greater certainty and cost effectiveness: (i) further strengthening carbon pricing, for example through automatically rising price floors for the national ETS after 2026; (ii) harmonizing carbon pricing to reduce cross-sector differences in marginal abatement costs; and (iii) introducing feebates (revenue neutral taxsubsidy schemes) to reinforce incentives at the sectoral level. The paper also studies the distributional impact of higher carbon pricing and suggests that reducing social security contributions can mitigate the regressive direct impact of higher carbon pricing on lowerincome households. Concerns with carbon leakages and firms’ competitiveness are best addressed through agreeing on an international carbon price floor.

Border Carbon Adjustments: Rationale, Design and Impact
Description: This paper assesses the rationale, design, and impacts of border carbon adjustments (BCAs). Large disparities in carbon pricing between countries raise concerns about competitiveness and emissions leakage. BCAs are potentially the most effective domestic instrument for addressing these challenges—but design details are critical. For example, limiting coverage of the BCA to energy-intensive, trade-exposed industries facilitates administration, and initially benchmarking BCAs on domestic emissions intensities would ease the transition for trading partners with emission-intensive production. It is also important to consider how to apply BCAs across countries with different approaches to emissions mitigation. BCAs alone do not solve the free-rider problem in carbon pricing, but might be a step to an effective international carbon price floor.

Brazil: Tax Expenditure Rationalization Within Broader Tax Reform
Description: The excessive complexity and burden of the Brazilian tax system, riddled by cumulative indirect taxes and heavy payroll contributions, have led to an accumulation of fiscal incentives aimed at reducing its burden on taxpayers and productive activities. Federal and subnational tax expenditures currently stand at over 5 percent of GDP. Rationalizing them can only be comprehensively feasible in the context of a broader sequenced tax reform, and could reduce resource misallocation and income inequality, as well as provide new revenues.

Income Versus Prices: How Does The Business Cycle Affect Food (In)-Security?
Description: We study how two aspects of food insecurity - caloric insufficiency and diet composition - are affected by aggregate economic fluctuations. The use of cross-country panel data allows us to adopt a global prospective on the identification of the macroeconomic determinants of food insecurity. Income shocks are the most relevant driver of food insecurity, displaying high elasticities at the early stages of economic development. The role of food price shocks is more limited. Social protection has a direct effect and mitigates the impact of income shocks. Effects are highly heterogeneous across a range of structural characteristics of the economy, highlighting the role of distributional aspects and of food import dependency.

Opening Up: Capital Flows and Financial Sector Dynamics in Low-Income Developing Countries
Description: Over the past two decades, many low-income developing countries have substantially increased openness towards external financing and have received large capital inflows. Using bank-level micro data, this paper finds that capital inflows have been associated with financial deepening through increases in bank loans, deposits, and wholesale funding. Domestic banks increase loans more than foreign banks. There are only modest signs of a build-up in financial vulnerabilities. Causality is examined through an instrumental variable approach and an augmented inverse-probability weighting estimator. These approaches indicate only limited evidence for global push effects, pointing towards the importance of domestic pull factors.

Still Not Getting Energy Prices Right: A Global and Country Update of Fossil Fuel Subsidies
Description: This paper provides a comprehensive global, regional, and country-level update of: (i) efficient fossil fuel prices to reflect their full private and social costs; and (ii) subsidies implied by mispricing fuels. The methodology improves over previous IMF analyses through more sophisticated estimation of costs and impacts of reform. Globally, fossil fuel subsidies were $5.9 trillion in 2020 or about 6.8 percent of GDP, and are expected to rise to 7.4 percent of GDP in 2025. Just 8 percent of the 2020 subsidy reflects undercharging for supply costs (explicit subsidies) and 92 percent for undercharging for environmental costs and foregone consumption taxes (implicit subsidies). Efficient fuel pricing in 2025 would reduce global carbon dioxide emissions 36 percent below baseline levels, which is in line with keeping global warming to 1.5 degrees, while raising revenues worth 3.8 percent of global GDP and preventing 0.9 million local air pollution deaths. Accompanying spreadsheets provide detailed results for 191 countries.

COVID-19 and the Informality-driven Recovery: The Case of Colombia's Labor Market
Description: This paper documents the impact of the COVID-19 pandemic and associated lockdowns on the Colombian labor market using household micro-data. About a quarter of employment was temporarily disrupted at the height of the first pandemic-induced lockdown in 2020. Women, the young, and the less educated were the most affected groups. Since then, a remarkable recovery, led by a rebound in informal employment, has taken place. By adjusting both employment levels and hours faster, the informal sector acted as an important margin of adjustment, particularly in those industries most affected by the first lockdown. The informal sector also appears to have played a role in decreasing the sensitivity of aggregate employment to more recent lockdowns in 2021, as the economy has learned to cope with pandemic restrictions, although the possibility of higher informality rates becoming embedded remains an substantial downside risk for long-term productivity.

Growth at Risk from Natural Disasters
Description: The paper analyzes the impact of natural disasters on per-capita GDP growth. Using a quantile regressions and growth-at-risk approach, the paper examines the impact of disasters and policy choices on the distribution of growth rather than simply its average. We find that countries that have in place disaster preparedness mechanisms and lower public debt have lower probability of witnessing a significant drop in growth as a consequence of a natural disaster, but our innovative methodology in this paper finds that the two policies are complements since their effectiveness vary across different disaster scenarios. While both are helpful for small to mid-size disasters, lower debt—and hence more fiscal space—is more beneficial in the face of very large disasters. A balanced strategy would thus involve both policies.

On the Benefits of Repaying
Description: This paper studies whether countries benefi t from servicing their debts during times of widespread sovereign defaults. Colombia is typically regarded as the only large Latin American country that did not default in the 1980s. Using archival research and formal econometric estimates of Colombia's probability of default, we show that in the early 1980s Colombia's fundamentals were not signifi cantly different from those of the Latin American countries that defaulted on their debts. We also document that the different path chosen by Colombia was due to the authorities' belief that maintaining a good reputation in the international capital market would have substantial long-term payoffs. We show that the case of Colombia is more complex than what it is commonly assumed. Although Colombia had to re-profi le its debts, high-level political support from the US allowed Colombia do to so outside the standard framework of an IMF program. Our counterfactual analysis shows that in the short to medium run, Colombia benefit ted from avoiding an explicit default. Speci fically, we find that GDP growth in the 1980s was higher than that of a counterfactual in which Colombia behaved like its neighboring countries. We also test whether Colombia's behavior in the 1980s led to long-term reputational benefi ts. Using an event study based on a large sudden stop, we find no evidence for such long-lasting reputational gains.
