Abstract
This paper explores the effect of oil price fluctuations on the stock returns of U.S. oil firms using an identification strategy through heteroskedasticity, exploiting the 2020 oil price crash. The results are twofold. First, a decline in oil prices significantly reduces oil firms’ stock returns. On average, a 1 percent decline in oil prices leads to a 0.44 percent decline in stock prices. Second, firm debt appears irrelevant in mediating the effect of oil prices on oil firms’ stock returns. Moreover, the muted role of debt was not likely caused by the liquidity backstop provided by the Federal Reserve.

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 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 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 The Marshall Plan: Then and Now(Washington, DC: World Bank, 2025-10-14)This paper is a product of the Development Policy Team, Development Economics.

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 Is There a Distress Risk Anomaly? Corporate Bond Spread as a Proxy for Default Risk(2010-05-01)Although financial theory suggests a positive relationship between default risk and equity returns, recent empirical papers find anomalously low returns for stocks with high probabilities of default. The authors show that returns to distressed stocks previously documented are really an amalgamation of anomalies associated with three stock characteristics -- leverage, volatility and profitability. In this paper they use a market based measure -- corporate credit spreads -- to proxy for default risk. Unlike previously used measures that proxy for a firm's real-world probability of default, credit spreads proxy for a risk-adjusted (or a risk-neutral) probability of default and thereby explicitly account for the systematic component of distress risk. The authors show that credit spreads predict corporate defaults better than previously used measures, such as, bond ratings, accounting variables and structural model parameters. They do not find default risk to be significantly priced in the cross-section of equity returns. There is also no evidence of firms with high default risk delivering anomalously low returns.Publication What Drives the Global “Land Rush”?(2011-10-01)The 2007-2008 upsurge in agricultural commodity prices gave rise to widespread concern about investors causing a "global land rush". Large land deals can provide opportunities for better access to capital, transfer of technology, and advances in productivity and employment generation. But they carry risks of dispossession and loss of livelihoods, corruption, deterioration in local food security, environmental damage, and long-term social polarization that led some countries to recently pass legislation restricting foreign land acquisition. To stimulate evidence-based debate, this paper explores determinants of foreign land acquisition for large-scale agriculture. It quantifies demand for land deals, showing it focused on Africa where land expansion is about 20 times the level it was in the past. The analysis uses data on bilateral investment relationships, together with newly constructed indicators of agro-ecological suitability in non-protected and forested areas with low population density as well as land rights security. It estimates gravity models that can help identify determinants of foreign land acquisition dedicated to large-scale agriculture. The results confirm the central role of agro-ecological potential as a pull factor. In contrast to the literature on foreign investment in general, the quality of the business climate is insignificant, whereas weak land governance and tenure security for current users make countries more attractive for investors. Implications for policy are discussed.Publication Liberalization, Technology Adoption, and Stock Returns(World Bank, Washington, DC, 2021-03)The paper investigates the pace of technology adoption in telecom technology post liberalization and its effect on stock returns using a new global panel data set. The results are twofold. First, the evidence points to the complementarity between telecom liberalization and regulatory independence in driving a sustained pace of technology adoption. Second, the results show a positive and economically significant effect of telecom adoption on stock returns, pointing to significant spillovers of telecom to the rest of the economy.Publication Raising the Bar on Corporate Governance : A Study of Eight Stock Exchange Indices(World Bank and the International Financial Corporation, Washington, DC, 2013-06)Stock exchanges around the world have launched Corporate Governance Indices (CGIs), sometimes as part of a broader Environment, Social, and Governance (ESG) initiative. The comprehensive analysis of these indices presented in this study is the first of its kind, and it reveals that CGIs have a positive impact, enhancing legal and regulatory frameworks by extending governance criteria to develop objective and measurable benchmarks. The study also shows that CGIs present companies with an opportunity to differentiate themselves in the market and, ultimately, offer companies an incentive to adopt better governance practices. Nevertheless, as the process for vetting and evaluation of companies for inclusion in the indices continues to evolve, access to underlying methodologies, disclosure of the ratings and self-assessments of individual companies, and of overall monitoring processes and procedures can still be enhanced. This study reviews the different approaches used by stock exchanges to build indices incorporating corporate governance. In the case of ESG indices, the focus is on the governance component of these indices. The study also draws lessons from the stock exchange's experiences and highlights success factors and shortcomings. In particular it addresses the following key questions: (i) what are the key drivers for stock exchanges to launch CGIs; (ii) what are the critical building blocks in the construction of a CGI; (iii) what are the risks faced by those investing in CGIs.Publication Corporate Governance and Bank Insolvency Risk : International Evidence(World Bank Group, Washington, DC, 2014-09)This paper finds that shareholder-friendly corporate governance is positively associated with bank insolvency risk, as proxied by the Z-score and the Merton's distance to default measure, for an international sample of banks over the 2004-08 period. Banks are special in that "good" corporate governance increases bank insolvency risk relatively more for banks that are large and located in countries with sound public finances, as banks aim to exploit the financial safety net. Good corporate governance is specifically associated with higher asset volatility, more nonperforming loans, and a lower tangible capital ratio. Furthermore, good corporate governance is associated with more bank risk-taking at times of rapid economic expansion. Consistent with increased risk-taking, good corporate governance is associated with a higher valuation of the implicit insurance provided by the financial safety net, especially in the case of large banks. These results underline the importance of the financial safety net and too-big-to-fail policies in encouraging excessive risk-taking by banks.

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.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 Argentina Country Climate and Development Report(World Bank, Washington, DC, 2022-11)The Argentina Country Climate and Development Report (CCDR) explores opportunities and identifies trade-offs for aligning Argentina’s growth and poverty reduction policies with its commitments on, and its ability to withstand, climate change. It assesses how the country can: reduce its vulnerability to climate shocks through targeted public and private investments and adequation of social protection. The report also shows how Argentina can seize the benefits of a global decarbonization path to sustain a more robust economic growth through further development of Argentina’s potential for renewable energy, energy efficiency actions, the lithium value chain, as well as climate-smart agriculture (and land use) options. Given Argentina’s context, this CCDR focuses on win-win policies and investments, which have large co-benefits or can contribute to raising the country’s growth while helping to adapt the economy, also considering how human capital actions can accompany a just transition.Publication Europe and Central Asia Economic Update, Spring 2025: Accelerating Growth through Entrepreneurship, Technology Adoption, and Innovation(Washington, DC: World Bank, 2025-04-23)Business dynamism and economic growth in Europe and Central Asia have weakened since the late 2000s, with productivity growth driven largely by resource reallocation between firms and sectors rather than innovation. To move up the value chain, countries need to facilitate technology adoption, stronger domestic competition, and firm-level innovation to build a more dynamic private sector. Governments should move beyond broad support for small- and medium-sized enterprises and focus on enabling the most productive firms to expand and compete globally. Strengthening competition policies, reducing the presence of state-owned enterprises, and ensuring fair market access are crucial. Limited availability of long-term financing and risk capital hinders firm growth and innovation. Economic disruptions are a shock in the short term, but they provide an opportunity for implementing enterprise and structural reforms, all of which are essential for creating better-paying jobs and helping countries in the region to achieve high-income status.Publication Morocco Economic Update, Winter 2025(Washington, DC: World Bank, 2025-04-03)Despite the drought causing a modest deceleration of overall GDP growth to 3.2 percent, the Moroccan economy has exhibited some encouraging trends in 2024. Non-agricultural growth has accelerated to an estimated 3.8 percent, driven by a revitalized industrial sector and a rebound in gross capital formation. Inflation has dropped below 1 percent, allowing Bank al-Maghrib to begin easing its monetary policy. While rural labor markets remain depressed, the economy has added close to 162,000 jobs in urban areas. Morocco’s external position remains strong overall, with a moderate current account deficit largely financed by growing foreign direct investment inflows, underpinned by solid investor confidence indicators. Despite significant spending pressures, the debt-to-GDP ratio is slowly declining.
