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.

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.

Commercial Real Estate and Macrofinancial Stability During COVID-19
Description: The COVID-19 pandemic crisis has severely shocked the commercial real estate (CRE) sector, which could have important implications for macro-financial stability going forward because of the large size of the sector and its strong interconnectedness with the real economy. Using a novel methodology, this paper quantifies vulnerabilities in the CRE sector and analyzes policy tools available to mitigate related risks. The analysis shows that CRE prices were overvalued in several major advanced economies in 2020:Q1. It also shows that such price misalignments increase the likelihood of future price corrections and exacerbate downside risks to future GDP growth. While the path of recovery in the sector will depend inherently on the pace of overall economic recovery and the structural shifts induced by the pandemic, easy financial conditions may contribute to an increase in financial vulnerabilities and persistent price misalignment. Macroprudential policy can, however, be effective in curbing the financial stability risks posed by the CRE sector.

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.

The Effects of Fiscal Measures During COVID-19
Description: This paper empirically examines the effects of fiscal policy measures during the COVID-19 pandemic, using a novel database of daily fiscal policy announcements—classified by type of fiscal measure—and high-frequency economic indicators for 52 countries from January 1 to December 31, 2020. The results suggest that fiscal policy announcements have been effective in stimulating economic activity, boosting confidence, and reducing unemployment, but their effect varies by type of measure and country characteristics. Emergency lifeline measures (which form the bulk of below-the-line measures) are more effective when containment policies are stringent, providing cashflow support to firms and households. Demand-support measures (which comprise most of above-the-line measures) are more effective when containment measures are relaxed.

Climate-Related Stress Testing: Transition Risk in Colombia
Description: This paper builds a framework to quantify the financial stability implications of climate-related transition risk in Colombia. We explore risks imposed on the banking system based on scenarios of an increase in the domestic carbon tax by using bank- and firm-level data. Focusing on the deterioration of firms’ balance sheets and the exposure of banks to different sectors, we assess the extent to which such policy shock would transmit from nonfinancial firms to the banking system. We observe that sectors are affected unevenly by a higher carbon tax. Agriculture, manufacturing, electricity, wholesale and retail trade, and transportation sectors appear to be the most important in the transmission of the risk to the banking system. Results also suggest that a large increase in the carbon tax can generate significant but likely manageable financial stability risks, and that a gradual increase in the carbon tax to meet a higher target over several years could be preferable in terms of financial risks. A gradual increase would also have the benefit of allowing for a smoother adjustment to higher carbon tax for stakeholders.
