Abstract
This paper contributes to the literature that explores the link between regulatory governance and sector performance. The paper develops an index of regulatory governance and estimates its impact on sector performance, showing that indeed regulation and its governance matter. The authors use two unique databases: (i) the World Bank Performance Database, which contains detailed annual data for 250 private and public electricity companies in Latin America and the Caribbean; and (ii) the Electricity Regulatory Governance Database, which contains data on several aspects of the governance of electricity agencies in the region. The authors run different models to explain the impacts of change in ownership and different characteristics of the regulatory agency on the performance of the utilities. The results suggest that the mere existence of a regulatory agency, regardless of the utilities' ownership, has a significant impact on performance. Furthermore, after controlling for the existence of a regulatory agency, the ownership dummies are still significant and with the expected signs. The authors propose an experience measure in order to identify the gradual impact of the regulatory agency on utility performance. The results confirm this hypothesis. In addition, the paper explores two different measures of governance, an aggregate measure of regulatory governance, and an index based on principal components, including autonomy, transparency, and accountability. The findings show that the governance of regulatory agencies matters and has significant effects on performance.

Publication Gender Gaps in the Performance of Small Firms: Evidence from Urban Peru(Washington, DC: World Bank, 2025-09-23)This paper estimates the gender gap in the performance of firms in Peru using representative data on both formal and informal firms. On average, informal female-led firms have lower sales, labor productivity, and profits compared to their male-led counterparts, with differences more pronounced when controlling for observable determinants of firm performance. However, gender gaps are only significant at the bottom of the performance distribution of informal firms, and these gaps disappear at the top of the distribution of informal firms and for formal firms. Possible explanations for the performance gaps at the bottom of the distribution include the higher likelihood of small, female-led firms being home-based, which is linked to lower profits, and their concentration in less profitable sectors. The paper provides suggestive evidence that household responsibilities play a key role in explaining the gender gap in firm performance among informal firms. Therefore, policies that promote access to care services or foster a more equal distribution of household activities may reduce gender productivity gaps and allow for a more efficient allocation of resources.Publication Global Poverty Revisited Using 2021 PPPs and New Data on Consumption(Washington, DC: World Bank, 2025-06-05)Recent improvements in survey methodologies have increased measured consumption in many low- and lower-middle-income countries that now collect a more comprehensive measure of household consumption. Faced with such methodological changes, countries have frequently revised upward their national poverty lines to make them appropriate for the new measures of consumption. This in turn affects the World Bank’s global poverty lines when they are periodically revised. The international poverty line, which is based on the typical poverty line in low-income countries, increases by around 40 percent to $3.00 when the more recent national poverty lines as well as the 2021 purchasing power parities are incorporated. The net impact of the changes in international prices, the poverty line, and new survey data (including new data for India) is an increase in global extreme poverty by some 125 million people in 2022, and a significant shift of poverty away from South Asia and toward Sub-Saharan Africa. The changes at higher poverty lines, which are more relevant to middle-income countries, are mixed.Publication Intergenerational Income Mobility around the World(Washington, DC: World Bank, 2025-07-09)This paper introduces a new global database with estimates of intergenerational income mobility for 87 countries, covering 84 percent of the world’s population. This marks a notable expansion of the cross-country evidence base on income mobility, particularly among low- and middle-income countries. The estimates indicate that the negative association between income mobility and inequality (known as the Great Gatsby Curve) continues to hold across this wider range of countries. The database also reveals a positive association between income mobility and national income per capita, suggesting that countries achieve higher levels of intergenerational mobility as they grow richer.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 Impact of Atlantic Hurricanes on Business Activity(Washington, DC: World Bank, 2025-09-22)This paper quantifies the short-run economic impact of 21 Atlantic hurricanes on U.S. local business activity from 2017 to 2024 using anonymized Mastercard transaction data aggregated by ZIP code. On average, hurricanes reduce merchant sales by 12.4 percent during the preparation, impact, and recovery phases—an estimated US$1.38 billion in lost revenue per storm. Substitution in spending across nearby areas or large online platforms is limited, indicating widespread local consumption declines. Economic disruption varies more by industry than storm intensity, with independent stores hit harder than chains. Local businesses with larger online presence face smaller, shorter sales declines, showing greater resilience.

Publication Regulatory Governance in Infrastructure Industries: Assessment and Measurement of Brazilian Regulators(Washington, DC: World Bank, 2006)The objective of this report is twofold: to provide a comprehensive assessment of the state of regulatory governance in infrastructure industries in Brazil and to suggest possible indicators for future monitoring. After the introduction, Section 2 sets up the analytical framework for the report, identifying key components of regulatory governance, namely, autonomy (political and financial), procedures for decision making, instruments (including personnel), and accountability. Section 3 assesses each of these components in practice, reporting the results of a survey with 21 regulatory agencies in Brazil, which was designed and implemented by the research team in 2005. Section 4 measures regulatory governance based on three related indexes, ranks the Brazilian regulators among themselves, and compares the proposed indexes with two other indicators available in the literature. Section 5 presents the conclusions.Publication Governance of Indian State Power Utilities : An Ongoing Journey(Washington, DC: World Bank Group, 2014-09-25)By the late 1990s, the technical and financial performance of the power sector in India had deteriorated to the point where the Government of India had to step in to bail out the state utilities, almost all of which were vertically integrated state electricity boards (SEBs). Considering that the dismal performance of state utilities reflected internal and external shortfalls in governance, the new Electricity Act of 2003 (EA 2003) mandated the unbundling and corporatization of the SEBs, along with the establishment of independent regulators. This was expected to bring about a more accountable and commercial performance culture, with concomitant results in improved utility performance. The rest of this review is organized as follows. Chapter two summarizes the institutional context and relevant developments over the past two decades. Chapter three focuses on the corporate governance agenda adopted by the government and its implementation, specifically relating to the structure and functioning of utility boards of directors. Chapter four reviews SERC regulatory governance. Chapter five analyzes the correlation between key indicators of the quality of regulatory and corporate governance and utility financial performance. And chapter six concludes.Publication Infrastructure Governance and Corruption : Where Next?(World Bank, Washington, DC, 2007-08)Governance is central to development outcomes in infrastructure, not least because corruption (a symptom of failed governance) can have significantly negative impact on returns to infrastructure investment. This conclusion holds whether infrastructure is in private or public hands. This paper looks at what has been learned about the role of governance in infrastructure, provides some recent examples of reform efforts and project approaches, and suggests an agenda for greater engagement - primarily at the sector level - to improve governance and reduce the development impact of corruption. The discussion covers market structure, regulation, state-owned enterprise reform, planning and budgeting, and project design.Publication Do Regulation and Institutional Design Matter for Infrastructure Sector Performance?(World Bank, Washington, DC, 2007-10)This paper evaluates the impact of economic regulation on infrastructure sector outcomes. It tests the impact of regulation from three different angles: aligning costs with tariffs and firm profitability; reducing opportunistic renegotiation; and measuring the effects on productivity, quality of service, coverage, and prices. The analysis uses an extensive data set of about 1,000 infrastructure concessions granted in Latin America from the late 1980s to the early 2000s. The analysis finds that as the theory indicates, regulation matters. The empirical work here reported shows that in three relevant economic aspects-aligning costs and tariffs; dissuading renegotiations; and improving productivity, quality of service, coverage, and tariffs-the structure, institutions, and procedures of regulation matter. Thus, significant efforts should continue to be made to improve the structure, quality, and institutionality of regulation. Regulation matters for protecting both consumers and investors, for aligning closely financial returns and the costs of capital, and for capturing higher levels of benefits from the provision of infrastructure services by the private sector.Publication Governance in State-Owned Enterprises Revisited : The Cases of Water and Electricity in Latin America and the Caribbean(2011-08-01)This paper studies the governance structure of state-owned enterprises in the water and electricity sectors of Latin America and the Caribbean. Through a unique dataset, the paper compares 44 leading state companies of the region based on an aggregate measure of corporate governance and six salient aspects of their design: board, chief executive officer, performance orientation, management, legal framework, and transparency/disclosure. The results indicate the need for improvement in areas such as the selection and appointment of directors to the board and the performance-orientation of the enterprises. The paper also highlights the importance of discussing the management of state-owned enterprises in the wider context of public sector governance, with particular focus on accountability. Moreover, it recognizes the role of accountability as central in the management of state-owned enterprises, recommending a better understanding of regulation and performance management. The paper finds a positive correlation between corporate governance and the utilities' performance. Among the different aspects of corporate governance, performance orientation and professional management seem to be the highest contributors to well-performing state-owned enterprises. State-owned enterprises in the electricity sector show higher governance levels than those in the water sector.

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 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 Lebanon Economic Monitor, Fall 2022(Washington, DC, 2022-11)The economy continues to contract, albeit at a somewhat slower pace. Public finances improved in 2021, but only because spending collapsed faster than revenue generation. Testament to the continued atrophy of Lebanon’s economy, the Lebanese Pound continues to depreciate sharply. The sharp deterioration in the currency continues to drive surging inflation, in triple digits since July 2020, impacting the poor and vulnerable the most. An unprecedented institutional vacuum will likely further delay any agreement on crisis resolution and much needed reforms; this includes prior actions as part of the April 2022 International Monetary Fund (IMF) staff-level agreement (SLA). Divergent views among key stakeholders on how to distribute the financial losses remains the main bottleneck for reaching an agreement on a comprehensive reform agenda. Lebanon needs to urgently adopt a domestic, equitable, and comprehensive solution that is predicated on: (i) addressing upfront the balance sheet impairments, (ii) restoring liquidity, and (iii) adhering to sound global practices of bail-in solutions based on a hierarchy of creditors (starting with banks’ shareholders) that protects small depositors.Publication The Journey Ahead(Washington, DC: World Bank, 2024-10-31)The Journey Ahead: Supporting Successful Migration in Europe and Central Asia provides an in-depth analysis of international migration in Europe and Central Asia (ECA) and the implications for policy making. By identifying challenges and opportunities associated with migration in the region, it aims to inform a more nuanced, evidencebased debate on the costs and benefits of cross-border mobility. Using data-driven insights and new analysis, the report shows that migration has been an engine of prosperity and has helped address some of ECA’s demographic and socioeconomic disparities. Yet, migration’s full economic potential remains untapped. The report identifies multiple barriers keeping migration from achieving its full potential. Crucially, it argues that policies in both origin and destination countries can help maximize the development impacts of migration and effectively manage the economic, social, and political costs. Drawing from a wide range of literature, country experiences, and novel analysis, The Journey Ahead presents actionable policy options to enhance the benefits of migration for destination and origin countries and migrants themselves. Some measures can be taken unilaterally by countries, whereas others require close bilateral or regional coordination. The recommendations are tailored to different types of migration— forced displacement as well as high-skilled and low-skilled economic migration—and from the perspectives of both sending and receiving countries. This report serves as a comprehensive resource for governments, development partners, and other stakeholders throughout Europe and Central Asia, where the richness and diversity of migration experiences provide valuable insights for policy makers in other regions of the world.
