The Sectoral Trade Losses from Financial Crises
Description: The “Great Trade Collapse” triggered by the 2008-09 crisis calls for a careful assessment of the trade losses from financial crises. We adopt a more detailed perspective by looking at the response of different types of trade (i.e. agricultural, mining, and manufactured goods, and services) following various types of financial crises (i.e. debt, banking, and currency crises). Estimations performed on the 1980-2018 period using a combination of impact assessment and local projections to capture a causal dynamic effect running from financial crises to the trade activity show that the collapse of total trade is long-lasting and mainly driven by the fall of manufacturing and to some extent services trade. These causal effects are found to operate through three channels: a structural, a demand-side, and a supply-side channel. By contributing to the understanding of the trade effects of financial crises, our analysis provides insightful support for the design and implementation of policies aimed at coping with these effects.

Fintech Potential for Remittance Transfers: A Central America Perspective
Description: This paper analyzes the potential for fintech to facilitate cheaper and more efficient remittances, and to enhance financial inclusion in Central America. Digital remittances remain nascent in the region, primarily reflecting behavioral inertia, small cost advantages of digital over traditional channels, and inadequate financial literacy. Through expanded alliances between traditional and fintech operators, digital remittances can further reduce transaction costs and reach those remote, low-income households in a timely and secure manner. A meaningful expansion of fintech remittances necessitates an enabling regulatory environment for digital financial services, and KYC and AML/CFT requirements proportionate to the value of transfers.

Understanding Chile’s Social Unrest in an International Perspective
Description: We aim to provide a broad descriptive overview of Chile’s social issues, in comparison to other countries and over time, in order to place the recent social unrest in historical and international perspectives which can help prepare the ground for future policy priorities. We follow an eclectic approach, classifying a broad set of indicators along six dimensions—inequality across: i) income; ii) perception; iii) access; iv) opportunity; v) redistribution; and vi) location. The analysis puts forward a set of descriptive findings. First, income inequality declined substantially but remains high, also compared to countries with similar level and path of development. Second, Chile seems to be one of the few countries in Latin America with declining inequality where perceived inequality actually increased. Third, notwithstanding an increase in social spending, access to essential services appears limited, particularly for middle and lower income classes, amid fast growth of out-of-pocket health expenses, relatively faster growth of cost of living for the relatively poorer, and remaining weaknesses in the pension and education systems. Fourth, inequality of opportunity is high, with limited competition. Fifth, fiscal redistribution has improved markedly, but remains low by international standards. Finally, inter-regional inequality has declined substantially over the last two decades, reaching levels similar to the OECD median.

Can International Technological Diffusion Substitute for Coordinated Global Policies to Mitigate Climate Change?
Description: In short, yes. I use a multi-region integrated assessment model with fuel-specific endogenous technical change to examine the impact of Europe and China reducing emissions to zero by mid-century. Without international technological diffusion this is insufficient to avoid catastrophic climate change. But when innovation can diffuse overseas, long-run temperature increases are limited to 3 degrees. This occurs because policy not only encourages green innovations but also dissuades dirty innovations which would otherwise spread. The most effective policy package in emissions-reducing regions is a research subsidy funded by a carbon tax, driven in the short term by the direct effect of the carbon tax on the composition of energy, and later by innovation induced by research subsidies. Green production subsidies are ineffective because they undermine incentives for innovation.

Effects of COVID-19 on Regional and Gender Equality in Sub-Saharan Africa: Evidence from Nigeria and Ethiopia
Description: The labor structure in sub-Saharan Africa is characterized by a high share of informal employment in the rural agricultural sector. The impact of COVID-19 on female employment may not appear to be large as the share of such employment is particularly high among women. Nevertheless, widespread income reduction was observed both in rural and urban households. This could worsen the opportunities for women as husbands’ control over the household resource is the norm. The paper also finds that rural children struggled to continue learning during school closures. Gender-sensitive policies are needed to narrow the gap during and post-pandemic.

COVID-19 in Latin America: A High Toll on Lives and Livelihoods
Description: Latin America was hit hard by Covid-19, both in terms of lives and livelihoods. Early lockdowns in the second quarter of 2020 prevented an explosion of deaths at the time but did not stop the pandemic from later wreaking havoc in the region. This paper investigates the dynamics of pandemics in Latin America and how it differed from elsewhere. We probe the role of non-pharmaceutical interventions; the effectiveness (or lack of thereof) lock-downs in Latin America; which structural factors contributed to the high death toll in Latin America, and the extent to which the epidemic harmed the economy. Finally, we briefly analyze the roots of the second-waves that started in the fourth quarter of 2020.

Technological Progress, Artificial Intelligence, and Inclusive Growth
Description: Advances in artificial intelligence and automation have the potential to be labor-saving and to increase inequality and poverty around the globe. They also give rise to winner-takes-all dynamics that advantage highly skilled individuals and countries that are at the forefront of technological progress. We analyze the economic forces behind these developments and delineate domestic economic policies to mitigate the adverse effects while leveraging the potential gains from technological advances. We also propose reforms to the global system of governance that make the benefits of advances in artificial intelligence more inclusive.

Labor Market Reform Options to Boost Employment in South Africa
Description: Raising South Africa’s low employment rate to levels seen in emerging market or advanced economy peers could raise GDP per capita by 50 to 60 percent and reduce income inequality dramatically in the long term. By putting further strain on an already fragile labor market, Covid-19 has raised the urgency of action. This paper reviews labor market policy and other reform options to enhance South Africa’s job market performance, drawing from international evidence and new analysis. We find much scope for improving the design of key labor market institutions—including collective bargaining and employment protection legislation—and active labor market policies to improve job seekers’ prospects. These reforms should come hand-in-hand with others, such as in the areas of education or product market regulation, that may work pay. Labor market and other reforms would primarily benefit disadvantaged groups such as youth.

Finance, Growth, and Inequality
Description: Finance and growth emerged as a distinct field of economics during the last three decades as economists integrated the fields of finance and economic growth and then explored the ramifications of the functioning of financial systems on economic growth, income distribution, and poverty. In this paper, I review theoretical and empirical research on the connections between the operation of the financial system and economic growth and inequality. While subject to ample qualifications, the preponderance of evidence suggests that (1) financial development—both the development of banks and stock markets—spurs economic growth and (2) better functioning financial systems foster growth primarily by improving resource allocation and technological change, not by increasing saving rates. Some research also suggests that financial development expands economic opportunities and tightens income distribution, primarily by boosting the incomes of the poor. This work implies that financial development fosters growth by expanding opportunities. Finally, and more tentatively, financial innovation—improvements in the ability of financial systems to ameliorate information and transaction costs—may be necessary for sustaining growth.

Asymmetric Non-Commodity Output Responses to Commodity Price Shocks
Description: This paper focuses on identifying potential asymmetric responses of non-commodity output growth in times of positive and negative commodity terms-of-trade shocks. Using a sample of 27 oil-exporting countries and a panel VAR method, the study finds: 1) the short-and medium-run response of real non-commodity GDP growth is larger for negative shocks than positive shocks; 2) this asymmetry is more pronounced in countries with weak pre-existing fundamentals–high levels of public debt and low levels of international reserves–which also serve to amplify the volatility of the response; 3) the output response to positive shocks is stronger following a sustained period of CTOT increases, while the impact of negative shocks on output are more damaging when they occur after a period of CTOT decline.
