The Great Carbon Arbitrage
Description: We measure the gains from phasing out coal as the average social cost of carbon times the quantity of avoided emissions. By comparing the present value of benefits from avoided emissions against the present value of costs of ending coal and replacing it with renewables, our conservative baseline estimate is that the world can realize a net gain of $85 trillion. This global net social benefit can be attained through an international agreement to phase out coal. We also explore how this net benefit is distributed across countries and find that most countries would benefit from a global coal phase-out even without any compensatory cross-country transfers. Finally, we estimate the size of public funds that must be committed under a blended finance arrangement to finance the cost of replacing coal with renewables.

The Current Account Income Balance: External Adjustment Channel or Vulnerability Amplifier?
Description: In terms of size, the net income balance (IB) is comparable to the trade balance (TB) for many countries. Yet the role of the IB in mitigating external vulnerabilities or complicating external adjustment remains underexplored. This paper studies the role of the IB in stabilizing or destabilizing the current account over the cycle and in crises. Our results show that, due to a negative correlation with the TB, the IB significantly dampens the time series volatility of the current account for most countries. However, the IB generally does not improve during crisis episodes, so current account adjustment occurs entirely through improvements in the TB. The paper also estimates IB semi-elasticities with respect to the exchange rate (ER). Semi-elasticities are small for most countries, so the IB is generally not a significant channel through which the ER stabilizes the current account, and trade-based semi-elasticities are, with some important exceptions, good proxies for current account semi-elasticities used in external sector assessments.

Voting Right Rotation, Behavior of Committee Members and Financial Market Reactions: Evidence from the U.S. Federal Open Market Committee
Description: Which Federal Reserve Bank presidents vote on the U.S. monetary policy committee depends on a mechanical, yearly rotation scheme. Rotation is without exclusion: nonvoting presidents do attend and participate in the meetings of the committee. We test two hypotheses about the dependence of presidents' behavior on voting status. (i) Loss compensation: presidents compensate the loss of the right to vote with an increased use of speeches and contributions. (ii) Motivation: presidents complement the right to vote with an increased use of speeches and contributions. The evidence favors the motivation hypothesis. Also, in years that presidents vote, their speeches move financial markets less than in years they do not vote. We argue that this vote discount is consistent with presidents’ communication behavior.

Macroeconomic Effects of Market Structure Distortions: Evidence from French Cartels
Description: We provide systematic evidence on cartels’ characteristics, using novel data on cases investigated by the French Competition Authority. These practices are widely spread across sectors and cartel members are typically among the top firms in their industries. In a model with heterogeneous firms and collusion, cartels amplify misallocation by charging supracompetitive markups. Breaking down French cartels would increase aggregate productivity by 2%, welfare by 3.5%, bringing the economy 37% closer to the efficient frontier. These numbers shed light on the aggregate importance of collusion.

For Whom the Bell Tolls: Climate Change and Inequality
Description: Climate change is the defining challenge of our time with complex and evolving dynamics. The effects of climate change on economic output and financial stability have received considerable attention, but there has been much less focus on the relationship between climate change and income inequality. In this paper, we provide new evidence on the association between climate change and income inequality, using a large panel of 158 countries during the period 1955–2019. We find that an increase in climate change vulnerability is positively associated with rising income inequality. More interestingly, splitting the sample into country groups reveals a considerable contrast in the impact of climate change on income inequality. While climate change vulnerability has no statistically significant effect on income distribution in advanced economies, the coefficient on climate change vulnerability is seven times greater and statistically highly significant in the case of developing countries due largely to weaker capacity for climate change adaptation and mitigation.

Rogue Waves: Climate Change and Firm Performance
Description: Climate change is an existential threat to the global economy and financial markets. There is a large body of literature documenting potential macroeconomic consequences of climate change, but firm-level empirical research on how climate change affects the performance of firms remains scarce. This paper aims to close this gap by empirically investigating the impact of climate change vulnerability on corporate performance using a large panel dataset of more than 3.3 million nonfinancial firms from 24 developing countries over the period 1997–2019. We find that nonfinancial firms operating in countries with greater vulnerability to climate change tend to experience difficulty in access to debt financing even at higher interest rates, while being less productive and profitable relative to firms in countries with lower vulnerability to climate change. We confirm these findings with alternative measures of climate change vulnerability. Furthermore, partitioning the sample reveals that these effects are significantly greater for smaller firms, especially in high-risk sectors and countries and countries with weaker capacity to adapt to and mitigate the consequences of climate change.

Jobs Impact of Green Energy
Description: This brief paper accompanies the Green Energy and Jobs tool, which is a simple excel-based tool to estimate the job-creation potential of greening the electricity sector. Specifically, it calculates the net job gains or losses from increasing the level of energy efficiency, and from increasing the share of clean and renewable electricity generation in the total electricity output mix. The tool relies on estimates of job multipliers in the literature, and adds evidence from firm-level data on the job-intensity of different energy sources. The paper illustrates applications of the tool using data from the IEA’s Sustainable Development Scenario compared to business-as-usual. This tool is intended to help country teams engage further on climate change issues in bilateral surveillance.

Strengthening Public Expenditure Efficiency: Investment and Social Spending in Bulgaria
Description: The scope for increasing public spending to meet Bulgaria’s development needs is limited by low revenue. Increasing the efficiency of spending is, therefore, crucial. This paper discusses how this can be achieved in four areas (public investment, social protection, health, and education). The methodology is based on a triple benchmarking. First, the level of public expenditure in each category is compared to other European countries. Second, the impact of spending is assessed against other European countries. Third, the input mix is analyzed to understand what components are responsible for the level of spending and for the quality of outcomes. Based on these results, the paper provides policy options for expenditure reform.

Finance Vaccine Equity: Funding for Day-Zero of the Next Pandemic
Description: A lack of timely financing for purchases of vaccines and other health products impeded the global response to the COVID-19 pandemic. Based on analysis of contract signature and delivery dates in COVID-19 vaccine advance purchase agreements, this paper finds that 60-75 percent of the delay in vaccine deliveries to low- and middle-income countries is attributable to their signing purchase agreements later than high-income countries, which placed them further behind in the delivery line. A pandemic Advance Commitment Facility with access to a credit line on day-zero of the next pandemic could allow low- and middle-income countries to secure orders earlier, ensuring a much faster and equitable global response than during COVD-19. The paper outlines four options for a financier to absorb some or all of the risk associated with the credit line and discusses how the credit would complement other proposals to strengthen the financing architecture for pandemic preparedness, prevention, and response.

Road Quality and Mean Speed Score
Description: We introduce a novel measure of cross-country road quality based on the travel mean speed between large cities from Google Maps. This measure is useful to assess road infrastructure and access gaps. Our Mean Speed (MS) score is easier to estimate and update than traditional gauges of road network quality which rely on official reports, surveys (i.e., World Economic Forum’s Quality of Roads Perception survey), or satellite imaging (i.e., World Bank’s Rural Access Index). In a sample of over 160 countries, we find that MS scores range between 38 km/h (23.6 mph) and 107 km/h (66.5 mph). We show that the MS score is a strong proxy for road quality and access.
