Robust Optimal Macroprudential Policy
Description: We consider how fear of model misspecification on the part of the planner and/or the households affects welfare gains from optimal macroprudential taxes in an economy with occasionally binding collateral constraints as in Bianchi (2011). On the one hand, there exist welfare gains from internalizing how borrowing decisions in good times affect the value of collateral during a crisis. On the other hand, interventions by a robust planner that has in mind a model far from the true underlying distribution of shocks, can result in negligible welfare gains, or even losses. This is because a policy that is robust to misspecification, as in Hansen and Sargent (2011), is optimal under a "worst-case'' scenario but not under alternative distributions of the state. A robust planner introduces taxes that are 5 percentage points higher but does not achieve a significant increase in welfare gains compared to a non-robust planner when the true underlying model is not the worst-case. If households also make choices that are robust to model misspecification, the gains are significantly reduced and a highly-robust planner "underborrows" and induces welfare losses. If, however, the worst-case scenario is indeed realized, then welfare gains are the largest possible.

Labor and Product Market Reforms and External Imbalances: Evidence from Advanced Economies
Description: We explore the impact of major labor and product market reforms on current account dynamics using a new “narrative” database of major changes in employment protection for regular workers and product market regulation for non-manufacturing industries covering 26 advanced economies over the past four decades. Our main finding is that product market deregulation is associated with a weakening of the current account, while labor market deregulation is associated with an improvement. These effects are transitory and driven by both saving and investment responses. Labor and product market reforms both have a more positive impact on the current account balance when implemented under weak macroeconomic conditions. Our results are broadly consistent with predictions from recent DSGE models with endogenous producer entry and labor market frictions.

India’s Approach to Open Banking: Some Implications for Financial Inclusion
Description: We examine how the development of the digital infrastructure known as the “India Stack”—including an interoperable payments system, a universal digital ID, and other features—is delivering on the government’s objective to expand the provision of financial services. While each individual component of the India Stack is important, we argue that its key overarching feature is a foundational approach of providing extensive public infrastructures and standards that generates important synergies across the layers of the Stack. Until recently, a large share of India’s population lacked access to formal banking services and was largely reliant on cash for financial transactions. The expansion of mobile-based financial services that enable simple and convenient ways to save and conduct financial transactions has provided a novel alternative for expanding the financial net. The Stack’s improved digital infrastructures have already allowed for a rapid increase in the use of digital payments and the entry of a range of competitors including fintech and bigtech firms.

Inequality and Locational Determinants of the Distribution of Living Standards in India
Description: Using 2011-12 consumption micro-data, we find that nearly one-third of the variation in living standards in India can be explained by location alone. Consumption levels and locational inequality are positively related. In effect, from an individual’s perspective, living standards are higher in richer, but more unequal, locations in India. The central factor behind these findings is the large difference in average consumption levels between rural and urban India and continued divergence in per-capita incomes between rich and poor states. Our results provide a possible explanation for the persistence of economic migration from rural to urban areas within a fast-growing emerging economy. While individuals cannot easily alter specific characteristics like their caste or religion, they have some freedom to change their location to enjoy better living standards.

Handle with Care: Regulatory Easing in Times of COVID-19
Description: The policy response to the COVID-19 shock included regulatory easing across many jurisdictions to facilitate the flow of credit to the economy and mitigate a further ampli-fication of the shock through tighter financial conditions. Using an intraday event study,this paper examines how stock prices—a key driver in financial conditions—reacted to regulatory easing announcements in a sample of 18 advanced economies and 8 emerging markets. The paper finds that overall, regulatory easing announcements contributed to looser financial conditions, but effects varied across sectors and tools. Financial regulatory easing led to lower valuations for financial sector stocks, and higher valuations for non-financial sector stocks, particularly for industries that are more dependent on bank financing. Furthermore, valuations declined and financial conditions tightened following announcements related to easier bank capital regulation while equity valuation rose and financial conditions loosened after those about liquidity regulation. Effects from non-regulatory financial measures appear to be generally more muted.

Post-Covid-19 Recovery and Resilience: Leveraging Reforms for Growth and Inclusion in Sub-Saharan Africa
Description: Covid-19 has exacerbated economic and social vulnerabilities across Sub-Saharan Africa (SSA). There is a risk that growth could be lower for longer, with a setback to development. Post-pandemic reforms thus become even more important, especially with constrained scope for fiscal and monetary stimuli. Reforms could boost per capita growth by an additional 0.3-1.3 percentage points, relative to the 1.9 percent average since 2010. Such growth would reduce per capita income doubling time from 37 years to about 22 years. Low-income countries stand to gain the most from reforms. The largest gains come from governance, products markets, and factor accumulation. Importantly, these reforms can be implemented in the post-pandemic environment characterized by weaker social and distributional outcomes.

Zombies on the Brink: Evidence from Japan on the Reversal of Monetary Policy Effectiveness
Description: How does unconventional monetary policy affect corporate capital structure and investment decisions? We study the transmission channel of quantitative easing and its potential diminishing returns on investment from a corporate finance perspective. Using a rich bank-firm matched data of Japanese firms with information on corporate debt and investment, we study how firms adjust their capital structure in response to the changes in term premia. Investment responds positively to a reduction in the term premium on average. However, there is a significant degree of cross-sectional variation in firm response: healthier firms increase capital spending and cash holdings, while financially vulnerable firms take advantage of lower long-term yields to refinance without increasing investment.

Credit Cycles, Fiscal Policy, and Global Imbalances
Description: We study the role that changes in credit and fiscal positions play in explaining current account fluctuations. Empirically, the current account declines when credit increases, and when the fiscal balance declines. We use a two-country model with financial frictions and fiscal policy to study these facts. We estimate the model using annual data for the U.S. and “a rest of the world” aggregate that includes main advanced economies. We find that about 30 percent of U.S. current account balance fluctuations are due to domestic credit shocks, while fiscal shocks explain about 14 percent. We evaluate simple macroprudential policy rules and show that they help reduce global imbalances. By taming the financial cycle, macroprudential rules that react to domestic credit conditions or to domestic house prices would have led to a smaller and less volatile U.S. current account deficit. We also show that a countercylical fiscal policy rule that stabilizes output growth reduces the level and volatility of the U.S. current account deficit.

How Does Profit Shifting Affect the Balance of Payments?
Description: Profit shifting by multinational enterprises—through manipulation of transfer prices of related-party trade, intragroup lending, or the location of intangibles—affects international flows, raising the question of its impact on the current account and external balances. This paper approaches this question theoretically and empirically. In theory, profit shifting distorts the components of the current account and bilateral current account balances but leaves a country’s aggregate net balance unaffected. There is, however, a real effect on current account balances, because taxes are paid to different jurisdictions. Moreover—in practice—the measured current account could change, because not all transactions are equally easy to track. Our panel empirical results broadly confirm that the current account balance tends to be, on average, unaffected by profit shifting, but taking heterogeneity into account we find that both the real tax effect and mismeasurement strengthen income balances—and thus the current account—in investment hubs.

Encouraging Formal Invoicing and Reducing the VAT Impact on Low-Income individuals
Description: This paper analyses and compares two different groups of tools, the first to encourage the use of invoices (or payment systems) and the second to refund the VAT to low-income individuals. The analysis contributes to the existing literature by providing a clear characterization between these two groups of tools that are too often misunderstood and offers clear guidance to policymakers on the benefits and pitfalls of them based on available empirical studies and novel data analysis. Briefly, the first group includes a set of regressive and distortive tools (such as, allowing deducting the VAT paid on personal consumption from the PIT and reducing the VAT rate for using electronic means of payments or registration), while the second group includes tools that are less distortionary and improve income distribution (tax credits and VAT rate reduction targeted only at low-income individuals). This paper also finds that allowing the deduction of personal consumption against the PIT’s taxable base (i) did not impact positively the VAT revenue in Guatemala and (ii) worsens the income distribution in Ecuador.
