Abstract
Evidence from high-income countries suggests that judges often exhibit in-group bias, favoring litigants that share an identity with the judge. However, there is little evidence on this phenomenon from the Global South. Collecting the available universe of High Court decisions in Kenya, this paper leverages the random assignment of cases to judges to evaluate the existence of in-group bias along gender and ethnic lines. It finds that, relative to a baseline win rate of 43 percent, defendants are 4 percentage points more likely to win if they share the judge's gender and 5 percentage points more likely to win if they share the judge~^!!^s ethnicity. The paper finds that the written judgements are on average shorter and less likely to be cited when defendants who are of the same gender or ethnicity as the judge win their case. This is consistent with in-group biased decisions being of lower quality. In addition, the findings show that female defendants are less likely to win the case if the judge exhibits stereotypical or negative attitudes towards women in their writings.

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 Extracting Lessons on Gender in the Oil and Gas Sector : A Survey and Analysis of the Gendered Impacts of Onshore Oil and Gas Production in Three Developing Countries(World Bank, Washington, DC, 2013-05)The oil, gas, and mining unit series publishes reviews and analyses of sector experience from around the world as well as new findings from analytical work. It places particular emphasis on how the experience and knowledge gained relates to developing country policy makers, communities affected by extractive industries, extractive industry enterprises, and civil society organizations. This paper explores the divergent experiences of women and men who live in areas that are directly affected by oil and gas development, and highlights how the industry specifically contributes to 'gender gaps' in the unequal distribution of assets and risks. Evidence from surveys and interviews with community members, company representatives, and government an official in oil-and gas-affected areas is analyzed and potential solutions are presented to reduce inequality, increase operational efficiency, reduce risks, and foster sustainable development. The paper aims to demonstrate how oil companies, policy makers, and donors, as well as citizens and nonprofits, can benefit from facilitating more equitable sharing of oil and gas wealth, with a particular focus on the inclusion of women. It points out the gains that can be realized through mutual collaboration to minimize harm for those people whose lives and environments are most directly impacted by the industry. Gender, as defined here, is differentiated from biological sex: gender describes the separate behaviors, identities and roles into which males and females are socialized, and contrasts the freedoms and constraints that come with these roles. This paper therefore examines how gender influences risks and opportunities in upstream areas of oil-rich, low income countries. The paper adopts a qualitative approach to research, presenting the perspectives of the people who live in the immediate vicinity of upstream operations and attempting to faithfully interpret what can be learned from their testimonies.Publication Gender and Economic Growth in Kenya : Unleashing the Power of Women(Washington, DC: World Bank, 2007)This report examines the legal, administrative, and regulatory barriers that are preventing women in Kenya from contributing fully to the Kenyan economy. Building on the 2004 Foreign Investment and Advisory Service (FIAS) report, "Improving the Commercial Legal Framework and Removing Administrative and Regulatory Barriers to Investment," this study looks at the bureaucratic barriers facing women in Kenya through a gender lens. The report makes specific recommendations to address gender-related barriers in the context of ongoing government and donor initiatives to encourage private sector development as the key driver of poverty reduction and economic growth, in line with Kenya's Economic Recovery Strategy for Wealth and Employment Creation 2003-2007 (ERS). Addressing these constraints will not only allow women to make a full contribution to the economy but also improve their livelihoods and those of their families and help create a more enabling environment for all businesses in Kenya.Publication Gender and Economic Growth in Uganda : Unleashing the Power of Women(Washington, DC: World Bank, 2005)Uganda is a leader in Sub-Saharan Africa, in recognizing linkages between economic growth and gender issues. These linkages are critical for achieving the Millennium Development Goals. The study assesses the legal and administrative barriers faced by women, as identified by the Bank's Foreign Investment Advisory Service (FIAS) and the International Finance Corporation's (IFC) Gender-Entrepreneurship-Markets Unit. The structure of the report mirrors that of the FIAS 2003 Administrative Barriers to Investment Report, and is designed to highlight the gender dimensions of that research to encourage further replication. The findings of this report indicate the considerable potential for economic growth that exists, if Uganda is to unleash the power of women, and support their full economic participation in the private sector. This assessment considers the relationship between gender and economic growth in Uganda in the context of promoting women's participation in business and entrepreneurship. Men and women both play substantial, albeit different, economic roles in the Ugandan economy. Each contributes about 50 percent of GDP, and women represent 39 percent of businesses with registered premises.Publication Earnings Inequality Within and Across Gender, Racial, and Ethnic Groups in Four Latin American Countries(World Bank, Washington, DC, 2008-04)Latin American countries are generally characterized as displaying high income and earnings inequality overall along with high inequality by gender, race, and ethnicity. However, the latter phenomenon is not a major contributor to the former phenomenon. Using household survey data from four Latin American countries (Bolivia, Brazil, Guatemala, and Guyana) for which stratification by race or ethnicity is possible, this paper demonstrates (using Theil index decompositions as well as Gini indices, and 90/10 and 50/10 percentile comparisons) that within-group earnings inequality rather than between-group earnings inequality is the main contributor to overall earnings inequality. Simulations in which the relatively disadvantaged gender and/or racial/ethnic group is treated as if it were the relatively advantaged group tend to reduce overall earnings inequality measures only slightly and in some cases have the effect of increasing earnings inequality measures.Publication Accounting for Gender Production from a Growth Accounting Framework in Sub-Saharan Africa(World Bank, Washington, DC, 2012-08)This paper draws on an expanded growth accounting framework to estimate the relative contribution of women to growth in Sub-Saharan Africa. Empirical results show a consistently positive contribution of women to growth in gross domestic product in the region, both during economic downturns and growth spurts. This is despite the absence of any valuation of home-produced goods and informal sector production, which accounts for the bulk of womens production, in national product and income accounts. Women's positive contribution is largely attributed to their increased rates of labor force participation in wage employment and the reduction in the gender gap in education in recent years.

Publication Dominican Republic Country Climate and Development Report(Washington, DC: World Bank, 2023-11-30)The Dominican Republic has made significant progress in boosting economic growth and reducing poverty, but it still faces challenges to achieve inclusive and equitable development, increase productivity, and improve the competitiveness and sustainability of primary sectors like agriculture, water, tourism, and energy. The National Development Strategy (NDS) and the National Multi‑Year Public Sector Plan (NPSP) aim to address development and climate challenges and promote a green, inclusive and resilient future. The DR is highly vulnerable to climate change, which is likely to compound existing development challenges. By 2050, climate change impacts are expected to decrease labor productivity and affect health, crop yields, tourism, infrastructure capital, and natural ecosystems such as forests and coastal areas. Climate change also poses risks to the financial system such as the banking sector's heightened credit exposure to tropical cyclones and droughts. Although the DR has a small carbon footprint, the country's GHG emissions have been rising, mainly in the energy, waste, and agricultural sectors. Fostering a low‑carbon growth path can support the country's climate change goals while bringing important development co‑benefits. The Dominican Republic CCDR employs a version of the MANAGE model. This CCDR further extends the model to incorporate the path of emissions from key sectors (transport, energy, AFOLU), and to incorporate DR‑specific climate damage functions to introduce the impact of climate change on the economy.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 Expanding Opportunities: Toward Inclusive Growth(World Bank, Washington, DC, 2023-04-04)South Asia’s outlook is shaped by both good and bad news in the global economy. Lower commodity prices, a strong recovery in the services sector, and reduced disruptions in value chains are aiding South Asia’s recovery but rising interest rates and uncertainty in financial markets are putting downward pressure on the region’s economies. Countries in South Asia, especially those with large external debt, face difficult tradeoffs as they respond to these pressures. Growth prospects have weakened, with large downside risks in most countries given limited fiscal space and depleting foreign reserves. Going forward, broad reform programs, including a sustainable fiscal outlook, are needed to put South Asia on a more robust and inclusive growth path. Inequality of opportunity, which is higher in South Asia than in other regions of the world, is both unfair and inefficient. Reducing inequality of opportunity and increasing economic mobility will help broaden countries’ tax base and boost support from the population for the critical reforms.Publication Middle Trade and Transport Corridor(Washington, DC: World Bank, 2023-11-26)The Middle Corridor (MC) is a multimodal transport corridor connecting China to Europe, which has been receiving elevated attention following Russia’s invasion of Ukraine. The MC links China, and Kazakhstan by rail through Dostyk or Khorgos/Altynkol, crosses Kazakhstan by rail to the Aktau Port, crosses the Caspian Sea to the Port of Baku/Alyat, and Azerbaijan and Georgia by rail to then either continue by rail to Europe through Türkiye or crossing the Black Sea. Due to inefficiencies and infrastructure gaps in Türkiye, the Black Sea route is currently preferred by operators. This report focuses on the route traversing Kazakhstan, Azerbaijan, and Georgia; a subsequent study will focus on Türkiye. The MC, with its numerous border crossings, transshipments between modes and operational inefficiencies, takes three times longer than the Northern route (via Russia) and is comparable in duration to the maritime route. As a result, it has consequently held a lower priority for long-distance trade.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.
