The 'Fiscal Presource Curse': Giant Discoveries and Debt Sustainability
Description: This paper investigates the dynamic impact of natural resource discoveries on government debt sustainability. We use a ‘natural experiment’ framework in which the timing of discoveries is treated as an exogenous source of within-country variation. We combine data on government debt, fiscal stress and debt distress episodes on a large panel of countries over 1970-2012, with a global repository of giant oil, gas, and mineral discoveries. We find strong and robust evidence of a ‘fiscal presource curse’, i.e., natural resources can jeopardize fiscal sustainability even before ‘the first drop of oil is pumped’. Specifically, we find that giant discoveries, mostly of oil and gas, lead to permanently higher government debt and, eventually, debt distress episodes, specially in countries with weaker political institutions and governance. This evidence suggest that the curse can be mitigated and even prevented by pursuing prudent fiscal policies and borrowing strategies, strengthening fiscal governance, and implementing transparent and robust fiscal frameworks for resource management.

Structural Breaks in Carbon Emissions: A Machine Learning Analysis
Description: To reach the global net-zero goal, the level of carbon emissions has to fall substantially at speed rarely seen in history, highlighting the need to identify structural breaks in carbon emission patterns and understand forces that could bring about such breaks. In this paper, we identify and analyze structural breaks using machine learning methodologies. We find that downward trend shifts in carbon emissions since 1965 are rare, and most trend shifts are associated with non-climate structural factors (such as a change in the economic structure) rather than with climate policies. While we do not explicitly analyze the optimal mix between climate and non-climate policies, our findings highlight the importance of the nonclimate policies in reducing carbon emissions. On the methodology front, our paper contributes to the climate toolbox by identifying country-specific structural breaks in emissions for top 20 emitters based on a user-friendly machine-learning tool and interpreting the results using a decomposition of carbon emission ( Kaya Identity).

Tax Policy for Inclusive Growth in Latin America and the Caribbean
Description: This study provides an overview of tax structures in LAC before the COVID-19 pandemic, compares it to OECD countries, and provides recommendations for growth-friendly and inclusive tax policy reforms. LAC countries collect significantly lower tax revenue relative to OECD countries and have tax structures that rely excessively on corporate-income taxes (CIT) while personal-income taxes (PIT) remain largely underutilized. LAC countries could strengthen their PIT to mobilize revenue and improve progressivity by addressing critical design flaws. Possible adverse growth effects could be mitigated by providing incentives to labor force participation and formalization (e.g., through earned-income tax credits). The ongoing global corporate income tax reforms present a great opportunity to reassess thoroughly the CIT in LAC. Specifically, reforms would need to focus on aligning CIT statutory rates with those of other regions—when assessed to be relatively high—to attract investment and alleviate profit shifting, and on broadening the corporate tax base. Value-added taxes (VAT) could be improved by tackling exemptions and reduced rates. Furthermore, while estimates of additional revenue from levying the VAT on the digital economy appear modest, taxing this sector as others in the economy is critical to avoid further tax base erosion.

Has COVID-19 Induced Labor Market Mismatch? Evidence from the US and the UK
Description: This paper studies whether labor market mismatch played an important role for labor market dynamics during the COVID-19 pandemic. We apply the framework of S¸ahin et al. (2014) to the US and the UK to measure misallocation between job seekers and vacancies across sectors until the third quarter of 2021. We find that mismatch rose sharply at the onset of the pandemic but returned to previous levels within a few quarters. Consequently, the total loss in employment caused by the rise in mismatch was smaller during the COVID-19 pandemic than during the Global Financial Crisis. The results are robust to considering alternative definitions of job seekers and to using a measure of effective job seekers in each sector. Preliminary evidence suggests that increased inactivity among older workers, the so called She-cession (particularly in the US) and shifting worker preferences amid strong labor demand are more prominent explanations for the persistent employment shortfall vis-à-vis pre-COVID levels.

Distribution Costs
Description: We provide the first direct estimates of distribution expenses incurred by manufacturing plants and assess their importance for aggregate output. Using a novel measure from the Indian Annual Survey of Industries, we document three key facts: (1) distribution expenses are large – they amount to over half of labor costs; (2) plants in the largest decile – relative to the smallest – spend over three times as much on distribution as a share of sales; and (3) between 2000 and 2010, distribution costs as a share of sales declined by one third. We develop a model of heterogeneous manufacturing firms that rely on the distribution sector to sell their goods across space. We quantify the model using the facts on size and systematic heterogeneity in distribution shares as well as newly constructed estimates of intranational trade. Accounting for firm heterogeneity in distribution requirements is important: welfare losses from low TFP in the distribution sector are amplified 1.5-fold. From 2000 to 2010, India saw an increase in intranational trade hand in hand with a decrease in the distribution share. In combination with the model, these trends suggest largescale decreases in both variable and fixed costs of distribution, leading to welfare gains of 58% over this ten year period.

Cars in Europe: Supply Chains and Spillovers during COVID-19 Times
Description: The auto sector is macro-critical in many European countries and constitutes one of the main supply chains in the region. Using a multi-sector and multi-country general equilibrium model, this paper presents a quantitative assessment of the impact of global pandemic-induced labor supply shocks—both directly and via supply chains—during the initial phase of the COVID-19 pandemic on the auto sector and aggregate activity in Europe. Our results suggest that these labor supply shocks would have a significant adverse impact on the major auto producers in Europe, with one-third of the decline in the value added of the car sector attributable to spillovers via supply chains within and across borders. Within borders, the pandemic-induced labor supply shocks in the services sector have a bigger adverse impact, reflecting their larger size and associated demand effects. Across borders, spillovers from the pandemic-induced labor supply shocks that originate in other European countries are larger than those that originate outside the region, though the latter are still sizable.

Winning the War? New Evidence on the Measurement and the Determinants of Poverty in the United States
Description: Using micro-data from household expenditure surveys, we document the evolution of consumption poverty in the United States over the last four decades. Employing a price index that appears appropriate for low income households, we show that poverty has not declined materially since the 1980s and even increased for the young. We then analyze which social and economic factors help explain the extent of poverty in the U.S. using probit, tobit, and machine learning techniques. Our results are threefold. First, we identify the poor as more likely to be minorities, without a college education, never married, and living in the Midwest. Second, the importance of some factors, such as race and ethnicity, for determining poverty has declined over the last decades but they remain significant. Third, we find that social and economic factors can only partially capture the likelihood of being poor, pointing to the possibility that random factors (“bad luck”) could play a significant role.

Preemptive Policies and Risk-Off Shocks in Emerging Markets
Description: We show that “preemptive” capital flow management measures (CFM) can reduce emerging markets and developing countries’ (EMDE) external finance premia during risk-off shocks, especially for vulnerable countries. Using a panel dataset of 56 EMDEs during 1996–2020 at monthly frequency, we document that countries with preemptive policies in place during the five year window before risk-off shocks experienced relatively lower external finance premia and exchange rate volatility during the shock compared to countries which did not have such preemptive policies in place. We use the episodes of Taper Tantrum and COVID-19 as risk-off shocks. Our identification relies on a difference-in-differences methodology with country fixed effects where preemptive policies are ex-ante by construction and cannot be put in place as a response to the shock ex-post. We control the effects of other policies, such as monetary policy, foreign exchange interventions (FXI), easing of inflow CFMs and tightening of outflow CFMs that are used in response to the risk-off shocks. By reducing the impact of risk-off shocks on countries’ funding costs and exchange rate volatility, preemptive policies enable countries’ continued access to international capital markets during troubled times.

The Role for Deposit Insurance Funds in Dealing with Failing Banks in the European Union
Description: This paper argues that in the European Union (EU) deposit insurance funds are too difficult to use in bank resolution and too easy to use outside resolution. The paper proposes reforms in three areas for the effective management of bank failures of small and medium-sized banks in the European Union: making resolution the norm for dealing with failing banks; establishing a common DIS for the European Union; and increasing funding and backstops for deposit insurance while removing constraints on their use for resolution measures. Without these changes, the European Union will continue to be challenged by banks that are too small for resolution and too large for liquidation.

A Measurement of Aggregate Trade Restrictions and their Economic Effects
Description: We develop a new Measure of Aggregate Trade Restrictions (MATR) using data from the IMF’s Annual Report on Exchange Arrangements and Exchange Restrictions. MATR is an empirical measure of how restrictive official government policy is towards the international flow of goods and services. MATR is simple, ad hoc, plausible, quantitative, easily updated, based solely on policy-relevant measures of trade policy, and covers an unbalanced sample of up to 157 countries annually between 1949 and 2019. MATR is strongly correlated with, but more comprehensive than, existing measures of openness and trade policy existing measures. We use MATR to show that trade restrictions are harmful for the economy and lead to significant contractions in output.
