Is Education Neglected in Natural Resources-Rich Countries? An Intergenerational Approach in Africa
Description: The literature on the effects of natural resources on education is mixed and inconclusive. In this paper, we adopt an innovative approach by exploring the effects of mineral discoveries and productions on intergenerational educational mobility (IM), linking parents to the children education levels for more than 14 million individuals across 28 African countries and 2,890 districts. We find that mineral discoveries and productions positively affect educational IM for primary education in Africa for individuals exposed to the mineral sites and living in districts with discoveries. Specifically, the probability of upward primary IM increases by 2.7 percentage points (pp.) following mineral discoveries and 6.7 pp. following mineral productions. Downward primary IM decreases by 1.2 pp. following both mineral discoveries and productions. These positive effects are increasing for individuals born later after discoveries and productions, for males, and individuals living in the urban area. However, no significant effects are found for secondary and tertiary educational IM. Finally, we explore the income and returns to education channels through which mineral discoveries and productions affect educational IM.

Economic Growth After Debt Surges
Description: Debt levels, both private and public, were already at record highs before the Covid-19 pandemic, and surged further in 2020. The high indebteness raises concerns whether it will undermine future growth prospects. This paper contributes to the ongoing debate by examining what happens to economic growth after debt surges. We apply a local projection method to a new dataset of debt surges in 190 countries between 1970 and 2020. Our results show that the relationship between debt surges and economic growth are complex. Debt surges tend to be followed by weaker economic growth and persistently lower output. However, this negative relationship does not always hold. Surges in public debt tend to have the most negative impact on future growth prospects. This is particularly the case if the economy is already operating with a large positive output gap. Debt surges also tend to be followed by weaker economic growth if the initial debt levels are high, especially for private debt surges. Our results also show how debt surges impact future growth. Public debt surges are associated with especially weaker private and public investment, although both private and public consumption are also negatively affected. Surges in corporate debt are followed by lower private and public investment.

Exchange-Rate Swings and Foreign Currency Intervention
Description: This paper develops a new approach for exploring the effectiveness of foreign currency intervention, focusing on real exchange cycles. Using band spectrum regression methods, it examines the role of macroeconomic fundamentals in determining the equilibrium real exchange rate at short-, medium-, and low frequencies. Next, it assesses the effectiveness of FX intervention depending on the degree of cycle-specific misalignments for 26 advanced- and emerging market economies, covering the period 1990–2018, and using different techniques to mitigate endogeneity concerns. Evidence supports the hypothesis that central banks can lean effectively against short-run cyclical misalignments of the real exchange rate. The effects are present in quarterly data—i.e., at policy-relevant horizons. The effectiveness of intervention rises with the size of the misalignment, and with the duration of one-sided interventions. FX sales appear to be somewhat more effective than FX purchases, and intervention is less effective in more liquid FX markets.

Do IMF Programs Stimulate Private Sector Investment?
Description: This paper provides new evidence on the role of IMF programs in stimulating private sector investments. Using detailed firm-level data on tangible fixed assets and a local projection methodology, we first estimate the dynamic response of firm investments to the approval of an IMF arrangement. We find that distinguishing between GRA and PRGT financing matters for the path of firm investment and its growth, and we also document the presence of two financial channels; the degree of firms’ external financial dependence and firms’ sectoral uncertainty. Exploiting these firm-level characteristics, we employ a difference-in-differences approach to understand the mechanisms through which the approval of an IMF arrangement propagates in the private sector. We find that the more firms rely on external finance and the more they are subject to uncertainty, the less binding these financial frictions become, and hence the more firms invest following a program approval. Finally, using ownership data, we find that private investments are stimulated more for domestic firms. The presence of a private investment transmission channel could help improve our understanding of what factors could affect the success and effectiveness of IMF programs.

Estimating Macro-Fiscal Effects of Climate Shocks From Billions of Geospatial Weather Observations
Description: A growing literature estimates the macroeconomic effect of weather using variations in annual country-level averages of temperature and precipitation. However, averages may not reveal the effects of extreme events that occur at a higher time frequency or higher spatial resolution. To address this issue, we rely on global daily weather measurements with a 30-km spatial resolution from 1979 to 2019 and construct 164 weather variables and their lags. We select a parsimonious subset of relevant weather variables using an algorithm based on the Least Absolute Shrinkage and Selection Operator. We also expand the literature by analyzing weather impacts on government revenue, expenditure, and debt, in addition to GDP per capita. We find that an increase in the occurrence of high temperatures and droughts reduce GDP, whereas more frequent mild temperatures have a positive impact. The share of GDP variations that is explained by weather as captured by the handful of our selected variables is much higher than what was previously implied by using annual temperature and precipitation averages. We also find evidence of counter-cyclical fiscal policies that mitigate adverse weather shocks, especially excessive or unusually low precipitation episodes.

Legal Gender Equality as a Catalyst for Convergence
Description: The unequal treatment of women in the law is one of the most visible forms of gender inequality. Prevalent legal constraints on the basis of gender prevent women, and thereby economies, from reaching their true potential. In this regard, this paper (i) documents the evolution of gender discriminatory laws around the globe, and (ii) sheds light on the role of legal gender equality in income convergence across countries. It shows that despite the remarkable progress toward gender equality in the law over the last five decades, the legal environment across the world is still far from providing a level playing field for women. Moreover, cross-country gaps in gender discriminatory laws have persisted and even widened over the years, meaning that some countries have lagged behind the progress in repealing the laws that act as a barrier to women’s economic inclusion. Based on a global sample since the 1970s, this paper finds that greater gender equality in the law facilitates cross-country income convergence over time. The results call for action and provide a reason to be optimistic going forward. They imply that legal reforms supportive of gender equality, which could indeed be actionable in the shorter term, help poorer countries catch up with the living standards in the advanced economies. These offer a window of opportunity in the post-Covid-19 period, given the adverse effects of the pandemic on economic growth and gender gaps.

Reducing Dollarization in the Caucasus and Central Asia
Description: Declining but still high dollarization rates in the Caucasus and Central Asia (CCA) region affect macroeconomic stability, monetary policy transmission, and financial sector development. Although several studies have investigated the dynamics of dollarization in the CCA, the relative roles of macrofinancial policies and financial market development in the de-dollarization process have not yet been assessed empirically. This paper takes stock of de-dollarization efforts and explores the short-term drivers of financial de‐dollarization in the CCA region. It highlights that there remains significant scope to further reduce dollarization through continued progress in strengthening macroeconomic policy frameworks and in developing markets and institutions.

Understanding and Predicting Systemic Corporate Distress: A Machine-Learning Approach
Description: In this paper, we study systemic non-financial corporate sector distress using firm-level probabilities of default (PD), covering 55 economies, and spanning the last three decades. Systemic corporate distress is identified by elevated PDs across a large portion of the firms in an economy. A machine-learning based early warning system is constructed to predict the onset of distress in one year’s time. Our results show that credit expansion, monetary policy tightening, overvalued stock prices, and debt-linked balance-sheet weaknesses predict corporate distress. We also find that systemic corporate distress events are associated with contractions in GDP and credit growth in advanced and emerging markets at different degrees and milder than financial crises.

Surging Energy Prices in Europe in the Aftermath of the War: How to Support the Vulnerable and Speed up the Transition Away from Fossil Fuels
Description: We estimate that the recent surge in international fossil fuel prices will raise European households’ cost of living in 2022 by close to 7 percent of consumption on average. Household burdens vary significantly across and within countries, but in most cases they are regressive. Policymakers have mostly responded to the shock with broad-based price-suppressing measures, including subsidies, tax reductions, and price controls. Going forward, the policy emphasis should shift rapidly towards allowing price signals to operate more freely and providing income relief to the vulnerable. The surge in energy prices will encourage energy conservation and investments in renewable energy, but the manyfold rise in natural gas prices could lead to a persistent switch towards coal. To ensure steady progress towards carbon emissions reduction goals, authorities could use the opportunity to strengthen carbon pricing when global fossil fuel prices decline in the future. Non-price incentives for investments in energy efficiency and renewable energy should also be enhanced, as envisaged in the RePowerEU plan.

Housing Boom and Headline Inflation: Insights from Machine Learning
Description: Inflation has been rising during the pandemic against supply chain disruptions and a multi-year boom in global owner-occupied house prices. We present some stylized facts pointing to house prices as a leading indicator of headline inflation in the U.S. and eight other major economies with fast-rising house prices. We then apply machine learning methods to forecast inflation in two housing components (rent and owner-occupied housing cost) of the headline inflation and draw tentative inferences about inflationary impact. Our results suggest that for most of these countries, the housing components could have a relatively large and sustained contribution to headline inflation, as inflation is just starting to reflect the higher house prices. Methodologically, for the vast majority of countries we analyze, machine-learning models outperform the VAR model, suggesting some potential value for incorporating such models into inflation forecasting.
