Sovereign Cocos
Description: We study a model of equilibrium sovereign default in which the government issues cocos (contingent convertible bonds) that stipulate a suspension of debt payments when the government faces liquidity shocks in the form of an increase of the bondholders' risk aversion. We find that in spite of reducing the frequency of defaults triggered by liquidity shocks, introducing cocos increases the overall default frequency. By mitigating concerns about liquidity, cocos make indebtedness and default risk more attractive for the government. In contrast, cocos that stipulate debt forgiveness when the government faces the shock, achieve larger welfare gains by reducing default risk.

Public Debt and Real GDP: Revisiting the Impact
Description: This paper provides new empirical evidence of the impact of an unanticipated change in public debt on real GDP. Using public debt forecast errors, we identify exogenous changes in public debt to assess the impact of a change in the debt to GDP ratio on real GDP. By analyzing data on gross public debt for 178 countries over 1995-2020, we find that the impact of an unanticipated increase in public debt on the real GDP level is generally negative and varies depending on other fundamental characteristics. Specifically, an unanticipated increase in the public debt to GDP ratio hurts real GDP level for countries that have (i) a high initial debt level or (ii) a rising debt trajectory over the five preceding years. On the contrary, an unanticipated increase in public debt boosts real GDP for countries that have (iii) a low-income level or (iv) completed the HIPC debt relief initiative.

High Performance Export Portfolio: Design Growth-Enhancing Export Structure with Machine Learning
Description: This paper studies the relationship between export structure and growth performance. We design an export recommendation system using a collaborative filtering algorithm based on countries' revealed comparative advantages. The system is used to produce export portfolio recommendations covering over 190 economies and over 30 years. We find that economies with their export structure more aligned with the recommended export structure achieve better growth performance, in terms of both higher GDP growth rate and lower growth volatility. These findings demonstrate that export structure matters for obtaining high and stable growth. Our recommendation system can serve as a practical tool for policymakers seeking actionable insights on their countries’ export potential and diversification strategies that may be complex and hard to quantify.

Monetary Policy Transmission and Policy Coordination in China
Description: We study the transmission of conventional monetary policy in China, focusing on the interaction between monetary and fiscal policy given the unique institutional set-up for macroeconomic policy making. Our results suggest some progress but also continued difficulties in the transmission of monetary policy. Similar to recent studies, we find evidence of monetary policy pass-through to interest rates. However, the impact of monetary policy measures that are not coordinated with fiscal policy is significantly weaker than that of coordinated measures. This suggests the need for further improvements to the interest-rate based framework.

India’s Banks: Lending to Productive Firms?
Description: Capital misallocation is widely thought to be an important factor underpinning productivity and income gaps between advanced and emerging economies. This paper studies how well Indian banks allocate capital across firms with varying levels of productivity. The analysis reveals that the link between productivity and bank credit growth is weaker for firms with significant ties to public sector banks, especially in years when public sector banks represent a large share of new credit. Large flows of credit to unproductive firms represent important missed growth opportunities for more productive firms. These results suggest that measures to improve governance of public sector banks, potentially including privatization, would help reduce capital misallocation.

Shocks to Inflation Expectations
Description: The consensus among central bankers is that higher inflation expectations can drive up inflation today, requiring tighter policy. We assess this by devising a novel method for identifying shocks to inflation expectations, estimating a semi-structural VAR where an expectation shock is identified as that which causes measured expectations to diverge from rationality. Using data for the United States, we find that a positive inflation expectations shock is deflationary and contractionary: inflation, output, and interest rates all fall. These results are inconsistent with the standard New Keynesian model, which predicts inflation and interest rate hikes. We discuss possible resolutions to this new puzzle.

Corporate Vulnerabilities in the Middle East, North Africa, and Pakistan in the Wake of COVID-19 Pandemic
Description: This paper analyzes corporate vulnerabilities in the Middle East, North Africa and Pakistan (MENAP hereafter) in the wake of the COVID-19 pandemic shock. Using a sample of nearly 700 firms from eleven countries in MENAP, we assess the non-financial corporate (NFC) sector’s liquidity and solvency risk and viability over the medium term under different stress test scenarios. Our findings suggest that the health crisis has exacerbated vulnerabilities in the corporate sector, though the effects are heterogenous across the region. Small firms, which entered the pandemic in a more vulnerable position, would remain under high liquidity stress over the medium term, putting a substantial share of these firms’ debt at risk of default. Similarly, liquidity needs of firms in contact-intensive sectors have also worsened and would remain elevated in 2022-23. We also show that an adverse scenario of subdued growth and premature withdrawal of policy support would impair the capacity to service interest expenses, especially among small firms, resulting in higher insolvency risk. Overall, our results indicate that some segments of the MENAP corporate sector could remain reliant on policy support during the recovery phase and that structural reforms are critical to save distressed but viable firms from bankruptcy and ensure an efficient liquidation of “zombie” firms.

The Return of Expansionary Austerity: Firms’ Investment Response to Fiscal Adjustments in Emerging Markets
Description: We study the response of corporate investment in Emerging Markets to unexpected fiscal shocks. We find that, although firm-level investment decreases on impact following unexpected public expenditure adjustments (classical Keynesian multiplier effect), it quickly rises above pre-shock levels. The rebound in investment is facilitated by fiscal space, flexible exchange rates, and more predictable fiscal policy. We also show that the composition of fiscal adjustments matters for investment’s response—compared to public investment adjustments, reductions in public consumption lead to larger private investment contractions on impact, but drive private investment to above pre-shock levels. Finally, we exploit firm-level heterogeneity in several dimensions, including to show that corporate investment’s recovery is stronger in firms in the tradable sector and in larger and less indebted firms, and to show that the long-run benefits to economic activity of the fiscal shock appear to outweigh its short-run costs.

Pandemic, Poverty, and Inequality: Evidence from India
Description: The paper presents estimates of poverty [extreme poverty PPP$1.9 and PPP$3.2] and consumption inequality in India for each of the years 2004-5 through the pandemic year 2020-21. These estimates include, for the first time, the effect of in-kind food subsides on poverty and inequality. Extreme poverty was as low as 0.8 percent in the pre-pandemic year 2019, and food transfers were instrumental in ensuring that it remained at that low level in pandemic year 2020. Post-food subsidy inequality at .294 is now very close to its lowest level 0.284 observed in 1993/94.

A Global Strategy to Manage the Long-Term Risks of COVID-19
Description: The pandemic is not over, and the health and economic losses continue to grow. It is now evident that COVID-19 will be with us for the long term, and there are very different scenarios for how it could evolve, from a mild endemic scenario to a dangerous variant scenario. This realization calls for a new strategy that manages both the uncertainty and the long-term risks of COVID-19. There are four key policy implications of such as strategy. First, we need to achieve equitable access beyond vaccines to encompass a comprehensive toolkit. Second, we must monitor the evolving virus and dynamically upgrade the toolkit. Third, we must transition from the acute response to a sustainable strategy toward COVID-19, balanced and integrated with other health and social priorities. Fourth, we need a unified risk-mitigation approach to future infectious disease threats beyond COVID-19. Infectious diseases with pandemic potential are a threat to global economic and health security. The international community should recognize that its pandemic financing addresses a systemic risk to the global economy, not just the development need of a particular country. Accordingly, it should allocate additional funding to fight pandemics and strengthen health systems both domestically and overseas. This will require about $15 billion in grants this year and $10 billion annually after that.
