Global Climate Change Mitigation, Fossil-Fuel Driven Development, and the Role of Financial and Technology Transfers: A Simple Framework
Description: Climate financing and compensation have emerged as key themes in the international climate mitigation debate. According to one argument in support of compensation, advanced economies (AEs) have used up much of the atmosphere’s absorptive capacity, thus causing global warming and blocking a similar, fossil-fuel driven development path for emerging markets and developing economies (EMDEs). This paper develops a simple model of a sequential, fossil-fuel driven development process to discuss these issues systematically. The results suggest: (i) AEs have typically a stronger interest in climate change mitigation than EMDEs, (ii) from an equity perspective, compensation is called for only if EMDEs are relatively small; (iii) there can also be an efficiency case for compensation, however, with AEs buying EMDEs out of some of their GHG emissions; (iv) ultimately, a superior option—for both the world’s climate and growth prospects—is the development of clean energy technologies by AEs and their transfer to EMDEs. The latter requires strong mitigation efforts by AEs even if EMDEs fail to play along initially.

Macrofinancial Causes of Optimism in Growth Forecasts
Description: We analyze the causes of the apparent bias towards optimism in growth forecasts underpinning the design of IMF-supported programs, which has been documented in the literature. We find that financial variables observable to forecasters are strong predictors of growth forecast errors. The greater the expansion of the credit-to-GDP gap in the years preceding a program, the greater its over-optimism about growth over the next two years. This result is strongest among forecasts that were most optimistic, where errors are also increasing in the economy’s degree of liability dollarization. We find that the inefficient use of financial information applies to growth forecasts more broadly, including the IMF’s forecasts in the World Economic Outlook and those produced by professional forecasters compiled by Consensus Economics. We conclude that improved macrofinancial analysis represents a promising avenue for reducing over-optimism in growth forecasts.

Monetary Policy and COVID-19
Description: We study the macroeconomic effects of the COVID-19 epidemic in a quantitative dynamic general equilibrium setup with nominal rigidities. We evaluate various containment policies and show that they allow to dramatically reduce the welfare cost of the disease. Then we investigate the role that monetary policy, in its capacity to manage aggregate demand, should play during the epidemic. According to our results, treating the observed output contraction as a standard recession leads to overly expansionary policy. Finally, we check how central banks should resolve the trade-off between stabilizing the economy and containing the epidemic. If no administrative restrictions are in place, the second motive prevails and, despite the deep recession, optimal monetary policy is in fact contractionary. Conversely, if sufficient containment measures are introduced, central bank interventions should be expansionary and help stabilize economic activity.

Tracing Productivity Growth Channels in the UK
Description: What drove the UK productivity slowdown post-GFC, and how is the post-Covid recovery expected to differ? This paper traces the sources of TFP growth in the UK over the last two decades through the lens of a structural model of innovation, using registry data on the universe of firms. The dominant innovation source in the pre-GFC decade were improvements by incumbent firms on their own products, whereas creation of new varieties by entrants took a leading role post-GFC. In the Covid recovery, survey data suggests that creative destruction (i.e., innovation replacing other firms’ products) is expected to gain importance. This emphasizes the need for growth policies that facilitate labor and capital reallocation across firms, in addition to R&D support.

Uncertainty and Public Investment Multipliers: The Role of Economic Confidence
Description: This paper investigates how macroeconomic uncertainty affects the fiscal multiplier of public investment. In theory, uncertainty can reduce the multiplier if the private sector becomes more cautious and does not respond to the fiscal stimulus. Conversely, it can increase the fiscal multiplier if public investment shocks improve private agents’ expectations about future economic outlook, and lead to larger private spending. Using the disagreement about GDP forecasts as a proxy for uncertainty, we find that unexpected increases in public investment have larger and longer-lasting effects on output, investment, and employment during periods of high uncertainty, with multipliers above 2, and the larger multipliers are not driven by economic slack. Public investment shocks are also found to boost private sector confidence during heightened uncertainty, driving-up expectations about future economic development which in turn magnify private sector response to the initial stimulus.

The Distributional Implications of the Impact of Fuel Price Increases on Inflation
Description: This paper investigates the response of consumer price inflation to changes in domestic fuel prices, looking at the different categories of the overall consumer price index (CPI). We then combine household survey data with the CPI components to construct a CPI index for the poorest and richest income quintiles with the view to assess the distributional impact of the pass-through. To undertake this analysis, the paper provides an update to the Global Monthly Retail Fuel Price Database, expanding the product coverage to premium and regular fuels, the time dimension to December 2020, and the sample to 190 countries. Three key findings stand out. First, the response of inflation to gasoline price shocks is smaller, but more persistent and broad-based in developing economies than in advanced economies. Second, we show that past studies using crude oil prices instead of retail fuel prices to estimate the pass-through to inflation significantly underestimate it. Third, while the purchasing power of all households declines as fuel prices increase, the distributional impact is progressive. But the progressivity phases out within 6 months after the shock in advanced economies, whereas it persists beyond a year in developing countries.

Okun's Law, Development, and Demographics: Differences in the Cyclical Sensitivities of Unemployment Across Economy and Worker Groups
Description: The negative and stable relationship between an economy’s aggregate demand conditions and overall unemployment is well-documented. We show that there is a large degree of heterogeneity in the cyclical sensitivities of unemployment across worker and economy groups. First, unemployment is more than twice as sensitive to aggregate demand in advanced as in emerging market and developing economies. Second, youth’s unemployment is twice as sensitive as that of adults’. Third, women’s unemployment is significantly less sensitive to demand than men’s in advanced economies. These findings point to the highly unequal impacts of the business cycle across worker and economy groups.

Gender Budgeting in G20 Countries
Description: Achieving gender equality remains a significant challenge, that has only deepened with the on-set of the COVID-19 pandemic. Gender budgeting (GB) can help promote gender equality by applying a gender perspective to fiscal policies and the budget process. This paper takes stock of GB practices in G20 countries and benchmarks country performance using a GB index and data gathered from an IMF survey. All G20 countries have enacted gender focused fiscal policies but the public financial management (PFM) tools to operationalize these policies are far less established. We find that notwithstanding heterogeneity across countries, the average G20 level of GB practice is relatively low. More progress has been made establishing GB frameworks and budget preparation tools than with budget execution, monitoring and auditing. Too few countries assess the upfront impact of policies on gender and/or evaluate ex-post the effectiveness of policies and programs. Where GB features are in place, they tend to operate as an ‘add-on’, rather than a strategic and integral part of resource allocation decisions. Progress with GB does not appear to be dependent on the level of country development. Key to future efforts will be harnessing opportunities for integrating GB tools into existing PFM systems and more closely linking GB initiatives with PFM reforms.

Establishing a Foreign Exchange Futures Market in China
Description: During China’s transition toward a more flexible exchange rate, it is essential to further develop its foreign exchange (FX) derivatives markets to meet the growing hedging needs associated with greater exchange rate fluctuations. Although over-the-counter (OTC) FX derivatives markets already exist in China, it lacks a FX futures market that offers critical complementarities. With standardized products, greater transparency and centralized oversight, a FX futures market can better satisfy the hedging needs of small and medium-sized enterprises and enhance regulatory efficiency. To address concerns regarding whether FX futures market will amplify the volatility of spot exchange rates, this paper analyzes the impact of establishing FX futures markets on spot market volatility using data from major emerging market economies. The result shows that FX futures market is not empirically associated with an increase in spot market volatility; in some cases, it is even associated with a decrease in spot market volatility. This paper further suggests that for a well-functioning FX futures market to be established, it is essential for China to substitute the inefficient documentation requirement of underlying exposures with a new set of market-oriented measures for the purpose of prudent regulation.

Forecasting Social Unrest: A Machine Learning Approach
Description: We produce a social unrest risk index for 125 countries covering a period of 1996 to 2020. The risk of social unrest is based on the probability of unrest in the following year derived from a machine learning model drawing on over 340 indicators covering a wide range of macro-financial, socioeconomic, development and political variables. The prediction model correctly forecasts unrest in the following year approximately two-thirds of the time. Shapley values indicate that the key drivers of the predictions include high levels of unrest, food price inflation and mobile phone penetration, which accord with previous findings in the literature.
