Uncertainty Premia, Sovereign Default Risk, and State-Contingent Debt
Description: We analyze how concerns for model misspecification on the part of international lenders affect the desirability of issuing state-contingent debt instruments in a standard sovereign default model à la Eaton and Gersovitz (1981). We show that for the commonly used threshold state-contingent bond structure (e.g., the GDP-linked bond issued by Argentina in 2005), the model with robustness generates ambiguity premia in bond spreads that can explain most of what the literature has labeled as novelty premium. While the government would be better off with this bond when facing rational expectations lenders, this additional source of premia leads to welfare losses when facing robust lenders. Finally, we characterize the optimal design of the state-contingent bond and show how it varies with the level of robustness. Our findings rationalize the little use of these instruments in practice and shed light on their optimal design.

Resource Misallocation Among Listed Firms in China: The Evolving Role of State-Owned Enterprises
Description: We document that publicly listed Chinese state-owned enterprises (SOEs) are less productive and profitable than publicly listed firms in which the state has no ownership stake. In particular, Chinese listed SOEs are more capital intensive and have a lower average product of capital than non-SOEs. These productivity differences increased between 2002 and 2009, and remain sizeable in 2019. Using a heterogeneous firm model of resource misallocation, we find that there are large potential productivity gains from reforms which could equalize the marginal products of listed SOEs and listed non-SOEs.

Trade and Inclusive Growth
Description: This paper surveys the literature on the relationship between international trade and inclusive growth. It examines claims that the rise in inequality in many countries can be attributed to the concurrent rise in trade competition, especially from EMEs like China, spurring trade tensions and protectionist measures. The paper investigates the conflicting literature showing the aggregate benefits of trade versus the adverse and persistent impact of trade, especially import competition, on specific industries and local communities. The paper then reviews the evidence for using trade policies and other complementary policies for adjustment and compensation to those groups adversely affected by trade.

Managing the Impact of Resource Booms on the Real Effective Exchange Rate: The Role of Financial Sector Development
Description: Whereas most of the literature related to the so-called “resource curse” tends to emphasize on institutional factors and public policies, in this research we focus on the role of the financial sector, which has been surprisingly overlooked. We find that countries that have financial systems with more depth, as well as those that actively manage their central banks’ balance sheets experience less exchange-rate appreciation than countries that do not. We analyze the relationship between these two findings and suggest that they appear to follow separate mechanisms.

Quantum Computing and the Financial System: Spooky Action at a Distance?
Description: The era of quantum computing is about to begin, with profound implications for the global economy and the financial system. Rapid development of quantum computing brings both benefits and risks. Quantum computers can revolutionize industries and fields that require significant computing power, including modeling financial markets, designing new effective medicines and vaccines, and empowering artificial intelligence, as well as creating a new and secure way of communication (quantum Internet). But they would also crack many of the current encryption algorithms and threaten financial stability by compromising the security of mobile banking, e-commerce, fintech, digital currencies, and Internet information exchange. While the work on quantum-safe encryption is still in progress, financial institutions should take steps now to prepare for the cryptographic transition, by assessing future and retroactive risks from quantum computers, taking an inventory of their cryptographic algorithms (especially public keys), and building cryptographic agility to improve the overall cybersecurity resilience.

Supply and Demand Effects of Unemployment Insurance Benefit Extensions: Evidence from U.S. Counties
Description: I use three decades of county-level data to estimate the effects of federal unemployment benefit extensions on economic activity. To overcome the reverse causality coming from the fact that benefit extensions are a function of state unemployment rates, I only use the within-state variation in outcomes to identify treatment effects. Identification rests on a differences-in-differences approach which exploits heterogeneity in county exposure to policy changes. To distinguish demand and supply-side channels, I estimate the model separately for tradable and non-tradable sectors. Finally I use benefit extensions as an instrument to estimate local fiscal multipliers of unemployment benefit transfers. I find (i) that the overall impact of benefit extensions on activity is positive, pointing to strong demand effects; (ii) that, even in tradable sectors, there are no negative supply-side effects from work disincentives; and (iii) a fiscal multiplier estimate of 1.92, similar to estimates in the literature for other types of spending.

The Short-Term Impact of COVID-19 on Labor Markets, Poverty and Inequality in Brazil
Description: We document the short-term impact of the COVID-19 pandemic on the Brazilian labor market focusing on employment, wages and hours worked using the nationally representative household surveys PNAD-Continua and PNAD COVID. Sectors most susceptible to the shock because they are more contact-intensive and less teleworkable, such as construction, domestic services and hospitality, suffered large job losses and reductions in hours. Given low income workers experienced the largest decline in earnings, extreme poverty and the Gini coefficient based on labor income increased by around 9.2 and 5 percentage points, respectively, due to the immediate shock. The government’s broad based, temporary Emergency Aid transfer program more than offset the labor income losses for the bottom four deciles, however, such that poverty relative to the pre-COVID baseline fell. At a cost of around 4 percent of GDP in 2020 such support is not fiscally sustainable beyond the short-term and ended in late 2020. The challenge will be to avoid a sharp increase in poverty and inequality if the labor market does not pick up sufficiently fast in 2021.

Proximity and Horizontal Policies: The Backbone of Export Diversification
Description: The lack of a clear link between general economic fundamentals and export diversification indicators in the literature has fueled the believe that industrial policies are an absolute requisite to diversify exports. This paper, however, does find a strong statistical connection between horizontal policies and diversification by making two novel changes to traditional methodologies: using export categories that lead to diversification (for example, manufactures) as dependent variables, and using a gravity-equation regression setting. Proximity to other economies explains about a third of cross-country heterogeneity in targeted exports, and four fifths together with horizontal policies. Australia, Chile, and New Zealand emerge as new role models for diversification policies.

Young Firms and Monetary Policy Transmission
Description: We investigate the role of business dynamism in the transmission of monetary policy by exploitingthe variation in firm demographics across U.S. states. Using local projections, we find that a larger fraction of young firms significantly mutes the effects of monetary policy on the labor market and personal income over the medium term. The firm entry rate and the employment share of young firms are key factors underpinning these results, which are robust to a battery of robustness tests. We develop a heterogeneous-firm model with age-dependent financial frictions that rationalizes the empirical evidence.

Education and Health for Inclusiveness
Description: We discuss existing shortfalls and inequalities in the accumulation of human capital—knowledge, skills, and health. We analyze their immediate and systemic causes, and assess the scope for public intervention. The broad policy goals should be to improve: the quality, and not just the quantity, of education and health care; outcomes for disadvantaged groups; and lifelong outcomes. The means to achieve these goals, while maximizing value for money, include: focusing on results rather than just inputs; moving from piecemeal interventions to systemic reform; and adopting a “whole-of-society” approach. Reforms must be underpinned by a robust evidence base.
