Brazil: Tax Expenditure Rationalization Within Broader Tax Reform
Description: The excessive complexity and burden of the Brazilian tax system, riddled by cumulative indirect taxes and heavy payroll contributions, have led to an accumulation of fiscal incentives aimed at reducing its burden on taxpayers and productive activities. Federal and subnational tax expenditures currently stand at over 5 percent of GDP. Rationalizing them can only be comprehensively feasible in the context of a broader sequenced tax reform, and could reduce resource misallocation and income inequality, as well as provide new revenues.

COVID-19 and the Informality-driven Recovery: The Case of Colombia's Labor Market
Description: This paper documents the impact of the COVID-19 pandemic and associated lockdowns on the Colombian labor market using household micro-data. About a quarter of employment was temporarily disrupted at the height of the first pandemic-induced lockdown in 2020. Women, the young, and the less educated were the most affected groups. Since then, a remarkable recovery, led by a rebound in informal employment, has taken place. By adjusting both employment levels and hours faster, the informal sector acted as an important margin of adjustment, particularly in those industries most affected by the first lockdown. The informal sector also appears to have played a role in decreasing the sensitivity of aggregate employment to more recent lockdowns in 2021, as the economy has learned to cope with pandemic restrictions, although the possibility of higher informality rates becoming embedded remains an substantial downside risk for long-term productivity.

Growth at Risk from Natural Disasters
Description: The paper analyzes the impact of natural disasters on per-capita GDP growth. Using a quantile regressions and growth-at-risk approach, the paper examines the impact of disasters and policy choices on the distribution of growth rather than simply its average. We find that countries that have in place disaster preparedness mechanisms and lower public debt have lower probability of witnessing a significant drop in growth as a consequence of a natural disaster, but our innovative methodology in this paper finds that the two policies are complements since their effectiveness vary across different disaster scenarios. While both are helpful for small to mid-size disasters, lower debt—and hence more fiscal space—is more beneficial in the face of very large disasters. A balanced strategy would thus involve both policies.

On the Benefits of Repaying
Description: This paper studies whether countries benefi t from servicing their debts during times of widespread sovereign defaults. Colombia is typically regarded as the only large Latin American country that did not default in the 1980s. Using archival research and formal econometric estimates of Colombia's probability of default, we show that in the early 1980s Colombia's fundamentals were not signifi cantly different from those of the Latin American countries that defaulted on their debts. We also document that the different path chosen by Colombia was due to the authorities' belief that maintaining a good reputation in the international capital market would have substantial long-term payoffs. We show that the case of Colombia is more complex than what it is commonly assumed. Although Colombia had to re-profi le its debts, high-level political support from the US allowed Colombia do to so outside the standard framework of an IMF program. Our counterfactual analysis shows that in the short to medium run, Colombia benefit ted from avoiding an explicit default. Speci fically, we find that GDP growth in the 1980s was higher than that of a counterfactual in which Colombia behaved like its neighboring countries. We also test whether Colombia's behavior in the 1980s led to long-term reputational benefi ts. Using an event study based on a large sudden stop, we find no evidence for such long-lasting reputational gains.

Assessing Chile's Pension System: Challenges and Reform Options
Description: Chile’s pension system came under close scrutiny in recent years. This paper takes stock of the adequacy of the system and highlights its challenges. Chile’s defined contribution system was quite influential when introduced, and was taken as an example by other countries. However, it is now delivering low replacement rates relative to OECD peers, as its parameters did not adapt over time to changing demographics and global returns, while informality persists in the labor market. In the absence of reforms, the system’s inability to deliver adequate outcomes for a large share of participants will continue to magnify, as demographic trends and low global interest rates will continue to reduce replacement rates. In addition, recent legislation allowing for pension savings withdrawals to counter the effects from the COVID-19 pandemic, is projected to further reduce replacement rates and increase fiscal costs. A substantial improvement in replacement rates is feasible, via a reform that raises contribution rates and the retirement age, coupled with policies that increases workers’ contribution density.

Enhancing Tax Compliance in the Dominican Republic Through Risk-based VAT Invoice Management
Description: Invoices document economic transactions and are thus critical to assess tax liabilities. We study a reform in the Dominican Republic that aimed to integrate invoice management into a broader, more comprehensive, risk-based compliance strategy. By rationing authorized invoices based on an extra scrutiny of each taxpayer’s compliance history, the reform led to significant and persistent improvements on filing, payment, and information reporting obligations and a modest increase in reported tax liabilities. Our study shows that deterrence effects over compliance behaviors are strengthened when the tax administration makes explicit and active use of taxpayers’ information, no matter if the invoicing framework is paper-based or electronic.

Optimal State Contingent Sovereign Debt Instruments
Description: This paper shows that the optimal sovereign lending contract is state-contingent when a government can default. It provides a theoretical basis for the specification of optimal state-contingent debt instruments (SCDIs) in countries subject to large shocks that can be observed and verified by all parties involved, such as natural disasters or global pandemics. The result is obtained as the endogenous solution to a contracting problem under time-inconsistency when a government cannot credibly commit to honor debt service obligations in all possible states of nature. It is shown that rational investors optimally offer SCDIs that include additional financing when the default constraint is binding, keeping the debtor engaged in the contractual relationship and avoiding asset loss. The debtor benefits because the contract implies net-positive financing when facing a large shock, increasing concurrent welfare, while maintaining access to financing in the future for consumption smoothing at the same terms as with precommitment. SCDIs require maintaining debt at a low level compared to the precommitment case, and also a fiscal consolidation when triggered to contain the increase in debt. Extension of the time inconsistency problem to add the taxation of capital returns shows that the optimal physical capital investment is also state-contingent.

Debt Dynamics in Emerging and Developing Economies: Is R-G a Red Herring?
Description: In the wake of the COVID-19 pandemic, debt levels in emerging and developing economies have surged raising concerns about fiscal sustainability. Historically, negative interest-growth differentials in these countries have played a debt-stabilizing role. But is this enough to prevent countries from falling into debt distress? Drawing from a sample of 150 emerging and developing economies going back to the 1970s, we find that interest-growth differentials have remained relatively low, dampening debt increases in the run up to a crisis. But in the face of persistent primary deficits, debt service tends to rise abruptly—particularly in emerging markets—and a fiscal crisis ensues. There is also evidence that a large part of the debt build-up around crises stems from valuation effects associated with external debt and the materialization of contingent liabilities. These findings underscore that, though not necessarily a red-herring, low interest-growth differentials cannot fully offset the deleterious effects of large fiscal deficits, forex exposures, or hidden debts.

Do Banks Price Environmental Transition Risks? Evidence from a Quasi-Natural Experiment in a Chinese Province
Description: This paper assesses the financial risks arising from transition toward a low-emission economy. The environmental DSGE model shows tightening environmental regulation impairs firms’ balance sheets, and consequently threatens financial stability in the short term. The empirical analysis indicates that following the implmentation of Clean Air Action Plan, the default rates of high-polluting firms in a Chinese province rose by around 80 percent. Joint equity commercial banks with higher level of independence were able to appropriately price in their exposure to transition risks, while the Big Five commercial banks failed to factor in such risks.

A Pandemic Forecasting Framework: An Application of Risk Analysis
Description: This paper introduces a simple, frequently and easily updated, close to the data epidemiological model that has been used for near-term forecast and policy analysis. We provide several practical examples of how the model has been used. We explain the epidemic development in the UK, the USA and Brazil through the model lens. Moreover, we show how our model would have predicted that a super infectious variant, such as the delta, would spread and argue that current vaccination levels in many countries are not enough to curb other waves of infections in the future. Finally, we briefly discuss the importance of how to model re-infections in epidemiological models.
