Abstract
This paper studies the dynamics of credit supply when a negative shock impacts a substantial share of bank loans. The analysis exploits the 2014 collapse of energy prices, using the universe of Mexican commercial bank loans. The findings show that, after the drop in energy prices, the credit default swap spreads (CDS) of firms in the energy sector soared, and banks that were more exposed to the energy sector increased even more their exposure ex post, by supplying loans to their larger debtors in the energy sector at lower interest rates. An increase of one standard deviation in ex-ante exposure to the energy sector increased loan volume to borrowers in the sector by 18 percent and reduced loan rates charged by 6 percent, even though borrower’s CDS spreads were widening. Highly exposed banks amplified this sector-specific shock to the rest of the economy by contracting lending to other sectors, with important real effects, as the borrowers could not switch credit suppliers. Finally, the energy price shock had a large negative impact on macro outcomes, especially in the capital-intensive secondary sector. Quantitatively, a one standard deviation increase in the exposure of a state's banks to the energy sector reduces its GDP by 1.8 percent.

Publication The Economic Value of Weather Forecasts: A Quantitative Systematic Literature Review(Washington, DC: World Bank, 2025-09-10)This study systematically reviews the literature that quantifies the economic benefits of weather observations and forecasts in four weather-dependent economic sectors: agriculture, energy, transport, and disaster-risk management. The review covers 175 peer-reviewed journal articles and 15 policy reports. Findings show that the literature is concentrated in high-income countries and most studies use theoretical models, followed by observational and then experimental research designs. Forecast horizons studied, meteorological variables and services, and monetization techniques vary markedly by sector. Estimated benefits even within specific subsectors span several orders of magnitude and broad uncertainty ranges. An econometric meta-analysis suggests that theoretical studies and studies in richer countries tend to report significantly larger values. Barriers that hinder value realization are identified on both the provider and user sides, with inadequate relevance, weak dissemination, and limited ability to act recurring across sectors. Policy reports rely heavily on back-of-the-envelope or recursive benefit-transfer estimates, rather than on the methods and results of the peer-reviewed literature, revealing a science-to-policy gap. These findings suggest substantial socioeconomic potential of hydrometeorological services around the world, but also knowledge gaps that require more valuation studies focusing on low- and middle-income countries, addressing provider- and user-side barriers and employing rigorous empirical valuation methods to complement and validate theoretical models.Publication It’s Not (Just) the Tariffs: Rethinking Non-Tariff Measures in a Fragmented Global Economy(Washington, DC: World Bank, 2025-10-22)As tariffs have declined, non-tariff measures (NTMs) have become central to trade policy, especially in high-income countries and regulated sectors like food and green technologies. Although NTMs may serve legitimate goals, they could also sort countries and firms into or out of markets based on compliance capacity and differences in product mix. Documenting recent advances in the estimation of ad valorem equivalents (AVEs), this paper uncovers new patterns of use and exposure of NTMs. High-income countries rely more heavily on NTMs relative to tariffs, while low- and middle-income countries face steeper AVEs on their exports. Firm-level evidence shows that NTMs disproportionately affect smaller firms, leading to market exit and concentration. Poorly designed NTMs can harm productivity and welfare, while coordinated, capacity-aware use can deliver inclusive outcomes. Policy design, transparency, and diagnostics must evolve to reflect the growing role—and risks—of NTMs in a fragmented global trade landscape.Publication Monitoring Global Aid Flows: A Novel Approach Using Large Language Models(Washington, DC: World Bank, 2025-11-04)Effective monitoring of development aid is the foundation for assessing the alignment of flows with their intended development objectives. Existing reporting systems, such as the Organisation for Economic Co-operation and Development’s Creditor Reporting System, provide standardized classification of aid activities but have limitations when it comes to capturing new areas like climate change, digitalization, and other cross-cutting themes. This paper proposes a bottom-up, unsupervised machine learning framework that leverages textual descriptions of aid projects to generate highly granular activity clusters. Using the 2021 Creditor Reporting System data set of nearly 400,000 records, the model produces 841 clusters, which are then grouped into 80 subsectors. These clusters reveal 36 emerging aid areas not tracked in the current Creditor Reporting System taxonomy, allow unpacking of “multi-sectoral” and “sector not specified” classifications, and enable estimation of flows to new themes, including World Bank Global Challenge Programs, International Development Association–20 Special Themes, and Cross-Cutting Issues. Validation against both Creditor Reporting System benchmarks and International Development Association commitment data demonstrates robustness. This approach illustrates how machine learning and the new advances in large language models can enhance the monitoring of global aid flows and inform future improvements in aid classification and reporting. It offers a useful tool that can support more responsive and evidence-based decision-making, helping to better align resources with evolving development priorities.Publication The Macroeconomic Implications of Climate Change Impacts and Adaptation Options(Washington, DC: World Bank, 2025-05-29)Estimating the macroeconomic implications of climate change impacts and adaptation options is a topic of intense research. This paper presents a framework in the World Bank's macrostructural model to assess climate-related damages. This approach has been used in many Country Climate and Development Reports, a World Bank diagnostic that identifies priorities to ensure continued development in spite of climate change and climate policy objectives. The methodology captures a set of impact channels through which climate change affects the economy by (1) connecting a set of biophysical models to the macroeconomic model and (2) exploring a set of development and climate scenarios. The paper summarizes the results for five countries, highlighting the sources and magnitudes of their vulnerability --- with estimated gross domestic product losses in 2050 exceeding 10 percent of gross domestic product in some countries and scenarios, although only a small set of impact channels is included. The paper also presents estimates of the macroeconomic gains from sector-level adaptation interventions, considering their upfront costs and avoided climate impacts and finding significant net gross domestic product gains from adaptation opportunities identified in the Country Climate and Development Reports. Finally, the paper discusses the limits of current modeling approaches, and their complementarity with empirical approaches based on historical data series. The integrated modeling approach proposed in this paper can inform policymakers as they make proactive decisions on climate change adaptation and resilience.Publication The State of Global Services Trade Policies: Evidence from Recent Data(Washington, DC: World Bank, 2025-10-28)The economic environment for services trade has changed dramatically over the past 15 years, driven by rapid technological progress that has expanded the possibilities for exchanging services. How has trade policy responded to these changes? How do policy stances in a wide range of service sectors compare across economies? With its unprecedented global coverage, the Services Trade Policy Database and the associated Services Trade Restrictions Index, developed jointly by the World Bank and the World Trade Organization, help address these questions. This paper makes three principal contributions. First, it offers an in-depth discussion of the current state of services trade policies and their differences across 134 economies and 34 services subsectors. Second, the paper reveals how recent (2016–22) changes in policy stances have seen progressive liberalization by lower-income economies but stabilization or even slight policy reversals in high-income economies. This dynamic differs fundamentally from the trend that unfolded after the Great Recession over 2008–16. Third, the paper shows the implications of policy changes over the past six years on services trade costs, and it showcases how the Services Trade Policy Database’s regulatory information can inform trade negotiations, regulatory analysis, and policy making. Alongside these contributions, the paper documents updates to the Services Trade Policy Database’s economy and sector coverage and explains the latest methodological improvements made to the World Bank–World Trade Organization Services Trade Restrictions Index.

Publication The Political Economy of Bank Lending(World Bank, Washington, DC, 2016-02)This study investigates the existence of political rents in bank lending, using a comprehensive loan-level data set of the universe of commercial loans in Mexico from 2003 to 2012. Identification relies on changes in the state of origin of a senate committee chairman as a source of exogenous variation in firms' political relationship. The study finds that banks offer favorable loan terms to politically connected firms with larger loan quantities, lower loan spreads, longer maturities, and lower collateral requirements. Furthermore, political loans exhibit higher default rates. To isolate the bank supply channel, a rich set of fixed-effects is included with various specifications. The favorable lending increases with the strength of a firm's political connection, varies gradually along the political cycle, and is mainly offered by large and domestic banks. Consistent with the quid pro quo hypothesis, the study finds that banks that extend political loans receive significantly more government borrowings with better credit quality. The study also shows that the greater credit supply due to political connection leads to a large and significant increase in firm-level employment and assets. The study provides estimates of the total social cost of political lending and net revenue for banks that are engaged in rent provision activity. Finally, a series of robustness tests are performed to rule out alternative mechanisms and explanations.Publication Expansionary Austerity(World Bank, Washington, DC, 2021-05)This paper shows expansionary fiscal austerity via reallocation of credit supply, but with a raise in poverty. For identification, the paper exploits the introduction of a Mexican law limiting the debt of subnational governments along with matched credit register, firm, bank, and state datasets. After the law, states with higher ex ante public debt grow substantially faster, despite larger fiscal consolidation (higher taxes and lower public expenditure). Banks operating in more indebted states reallocate credit supply away from local governments into private firms, with stronger effects for banks with higher exposure to local public debt, consistent with lowering crowding out. Effects only happen after the law, not before, and there are strong firm-level real effects associated. The reduction of crowding out is stronger for financially constrained firms and for firms operating in states with higher ex ante public spending on social services over infrastructure projects. In states more affected by the law, despite better economic effects, extreme poverty increases––especially in states with higher ex ante public spending on social services over infrastructure––consistent with a strong reduction for social services during the fiscal consolidation.Publication Market Power and the Transmission of Loan Subsidies(World Bank, Washington, DC, 2019-07)This paper studies credit allocation when government loan programs are distributed by private banks. The study focuses on Brazil, where private lenders can operate in two credit markets: competitive loans with own funding and earmarked loans that rely on government funds to finance firms at below-the-market interest rates. Using rich loan-level data between 2005-2016, the paper finds that banks are disproportionately more likely to extend earmarked loans to larger firms and firms with an existing credit relationship. The paper further documents a cross-selling strategy whereby banks increase the price of free-market loans of riskier borrowers that also obtain earmarked credit. Inadvertently, the government selects winners and losers, since mostly larger businesses, those that bank with the largest private lenders, and those willing to bundle free-market and earmarked loans disproportionately access the program.Publication Determinants of Long-Term versus Short-Term Bank Credit in EU Countries(World Bank, Washington, DC, 2015-10)This paper empirically examines the determinants of credit at different maturities across European Union countries during the last decade. The paper documents the lengthening of maturities since the early 2000s, and whether these patterns were driven by similar factors in advanced countries and in emerging market countries. Before the 2008 crisis, long-term credit expanded faster than short-term credit in most countries in the sample, and contracted less than short-term credit after 2008. The paper finds that domestic deposits and foreign liabilities were more important sources of funding in emerging market countries than in advanced countries. Moreover, trade openness and initial banking sector depth matter more for emerging market countries than for advanced countries.Publication The International Bank Lending Channel of Monetary Policy Rates and Quantitative Easing(World Bank Group, Washington, DC, 2015-03)This paper identifies the international credit channel of monetary policy by analyzing the universe of corporate loans in Mexico, matched with firm and bank balance-sheet data, and by exploiting foreign monetary policy shocks, given the large presence of European and U.S. banks in Mexico. The paper finds that a softening of foreign monetary policy increases the supply of credit of foreign banks to Mexican firms. Each regional policy shock affects supply via their respective banks (for example, U.K. monetary policy affects credit supply in Mexico via U.K. banks), in turn implying strong real effects, with substantially larger elasticities from monetary rates than quantitative easing. Moreover, low foreign monetary policy rates and expansive quantitative easing increase disproportionally more the supply of credit to borrowers with higher ex ante loan rates -- reach-for-yield -- and with substantially higher ex post loan defaults, thus suggesting an international risk-taking channel of monetary policy. All in all, the results suggest that foreign quantitative easing increases risk-taking in emerging markets more than it improves the real outcomes of firms.

Publication Europe and Central Asia Economic Update, Fall 2024: Better Education for Stronger Growth(Washington, DC: World Bank, 2024-10-17)Economic growth in Europe and Central Asia (ECA) is likely to moderate from 3.5 percent in 2023 to 3.3 percent this year. This is significantly weaker than the 4.1 percent average growth in 2000-19. Growth this year is driven by expansionary fiscal policies and strong private consumption. External demand is less favorable because of weak economic expansion in major trading partners, like the European Union. Growth is likely to slow further in 2025, mostly because of the easing of expansion in the Russian Federation and Turkiye. This Europe and Central Asia Economic Update calls for a major overhaul of education systems across the region, particularly higher education, to unleash the talent needed to reinvigorate growth and boost convergence with high-income countries. Universities in the region suffer from poor management, outdated curricula, and inadequate funding and infrastructure. A mismatch between graduates' skills and the skills employers are seeking leads to wasted potential and contributes to the region's brain drain. Reversing the decline in the quality of education will require prioritizing improvements in teacher training, updated curricula, and investment in educational infrastructure. In higher education, reforms are needed to consolidate university systems, integrate them with research centers, and provide reskilling opportunities for adult workers.Publication World Development Report 2006(Washington, DC, 2005)This year’s Word Development Report (WDR), the twenty-eighth, looks at the role of equity in the development process. It defines equity in terms of two basic principles. The first is equal opportunities: that a person’s chances in life should be determined by his or her talents and efforts, rather than by pre-determined circumstances such as race, gender, social or family background. The second principle is the avoidance of extreme deprivation in outcomes, particularly in health, education and consumption levels. This principle thus includes the objective of poverty reduction. The report’s main message is that, in the long run, the pursuit of equity and the pursuit of economic prosperity are complementary. In addition to detailed chapters exploring these and related issues, the Report contains selected data from the World Development Indicators 2005‹an appendix of economic and social data for over 200 countries. This Report offers practical insights for policymakers, executives, scholars, and all those with an interest in economic development.Publication World Development Report 2011(World Bank, 2011)The 2011 World development report looks across disciplines and experiences drawn from around the world to offer some ideas and practical recommendations on how to move beyond conflict and fragility and secure development. The key messages are important for all countries-low, middle, and high income-as well as for regional and global institutions: first, institutional legitimacy is the key to stability. When state institutions do not adequately protect citizens, guard against corruption, or provide access to justice; when markets do not provide job opportunities; or when communities have lost social cohesion-the likelihood of violent conflict increases. Second, investing in citizen security, justice, and jobs is essential to reducing violence. But there are major structural gaps in our collective capabilities to support these areas. Third, confronting this challenge effectively means that institutions need to change. International agencies and partners from other countries must adapt procedures so they can respond with agility and speed, a longer-term perspective, and greater staying power. Fourth, need to adopt a layered approach. Some problems can be addressed at the country level, but others need to be addressed at a regional level, such as developing markets that integrate insecure areas and pooling resources for building capacity Fifth, in adopting these approaches, need to be aware that the global landscape is changing. Regional institutions and middle income countries are playing a larger role. This means should pay more attention to south-south and south-north exchanges, and to the recent transition experiences of middle income countries.Publication Classroom Assessment to Support Foundational Literacy(Washington, DC: World Bank, 2025-03-21)This document focuses primarily on how classroom assessment activities can measure students’ literacy skills as they progress along a learning trajectory towards reading fluently and with comprehension by the end of primary school grades. The document addresses considerations regarding the design and implementation of early grade reading classroom assessment, provides examples of assessment activities from a variety of countries and contexts, and discusses the importance of incorporating classroom assessment practices into teacher training and professional development opportunities for teachers. The structure of the document is as follows. The first section presents definitions and addresses basic questions on classroom assessment. Section 2 covers the intersection between assessment and early grade reading by discussing how learning assessment can measure early grade reading skills following the reading learning trajectory. Section 3 compares some of the most common early grade literacy assessment tools with respect to the early grade reading skills and developmental phases. Section 4 of the document addresses teacher training considerations in developing, scoring, and using early grade reading assessment. Additional issues in assessing reading skills in the classroom and using assessment results to improve teaching and learning are reviewed in section 5. Throughout the document, country cases are presented to demonstrate how assessment activities can be implemented in the classroom in different contexts.Publication Digital Africa(Washington, DC: World Bank, 2023-03-13)All African countries need better and more jobs for their growing populations. "Digital Africa: Technological Transformation for Jobs" shows that broader use of productivity-enhancing, digital technologies by enterprises and households is imperative to generate such jobs, including for lower-skilled people. At the same time, it can support not only countries’ short-term objective of postpandemic economic recovery but also their vision of economic transformation with more inclusive growth. These outcomes are not automatic, however. Mobile internet availability has increased throughout the continent in recent years, but Africa’s uptake gap is the highest in the world. Areas with at least 3G mobile internet service now cover 84 percent of Africa’s population, but only 22 percent uses such services. And the average African business lags in the use of smartphones and computers as well as more sophisticated digital technologies that catalyze further productivity gains. Two issues explain the usage gap: affordability of these new technologies and willingness to use them. For the 40 percent of Africans below the extreme poverty line, mobile data plans alone would cost one-third of their incomes—in addition to the price of access devices, apps, and electricity. Data plans for small- and medium-size businesses are also more expensive than in other regions. Moreover, shortcomings in the quality of internet services—and in the supply of attractive, skills-appropriate apps that promote entrepreneurship and raise earnings—dampen people’s willingness to use them. For those countries already using these technologies, the development payoffs are significant. New empirical studies for this report add to the rapidly growing evidence that mobile internet availability directly raises enterprise productivity, increases jobs, and reduces poverty throughout Africa. To realize these and other benefits more widely, Africa’s countries must implement complementary and mutually reinforcing policies to strengthen both consumers’ ability to pay and willingness to use digital technologies. These interventions must prioritize productive use to generate large numbers of inclusive jobs in a region poised to benefit from a massive, youthful workforce—one projected to become the world’s largest by the end of this century.
