Abstract
This paper reviews recent literature on the impacts of various components of power sector reform on the performance of electric utilities in developing countries. Recent literature is heavily focused on statistical testing of the significance of the links between four components of sector reform (unbundling, private sector participation, regulation, and competition) and various performance indicators (relating to utility performance, user outcomes, and broader economic development). Some studies exhibit methodological shortcomings in failing to account for interactions between reforms or degrees of reform; however, others appear to be robust. The strongest result is that the introduction of private sector participation is linked to a significant improvement in labor productivity and distribution losses. Moreover, unbundling reforms in isolation is found to have hardly any significant impact on utility performance. The introduction of an independent regulator or competition is not generally significant across studies. A notable feature of all of the studies is very limited testing of the effects of policy introduction on performance indicators, such as bill collection and the duration and frequency of outages. Poor performance on these indicators of state-owned power companies is well documented and bill collection has been identified as a major hidden cost of unreformed power sectors. The materiality of the impact of private sector participation, on the various performance indictors found to be significant, is calculated for studies that provide sufficient information to do so. The size of the impact of private sector participation on utility performance is substantial in a couple of studies, although much more modest in others.

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 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 Geopolitical Fragmentation and Friendshoring(Washington, DC: World Bank, 2025-06-26)This paper examines the relationship between geopolitical fragmentation and friendshoring of foreign investments over time, countries, and sectors. The analysis uses comprehensive data on foreign direct investments covering greenfield projects, mergers and acquisitions, and stocks of affiliates, as well as data on four alternative measures of geopolitical distance between countries. The gravity estimations suggest that, first, geopolitical differences have a negative effect on foreign investments and the magnitude has heightened in the post-pandemic period compared to a decade ago. Second, it is primarily the companies from advanced Western economies whose foreign investment decisions are increasingly shaped by friendshoring forces. Finally, the paper shows that friendshoring is not only confined to strategic industries, implying that allocations of foreign direct investments may not solely reflect national security or resilience considerations.Publication Soaring Food Prices Threaten Recent Economic Gains in the EU(Washington, DC: World Bank, 2025-07-02)The surge in food prices following the 2021 economic rebound has become a significant concern for households, particularly low-income ones, in Bulgaria, Croatia, Poland, and Romania. Food price inflation, which surpasses general inflation rates, risks worsening poverty and food insecurity in these countries. This paper explores the distributional impacts of rising food prices and the effectiveness of government response measures. Low-income households, who allocate a larger share of their income to food, are disproportionately affected and are struggling to cope with unexpected expenses, leading to increased difficulties in accessing proper nutrition. Simulations indicate that rising food prices contribute to higher poverty rates and greater income inequality, especially among vulnerable populations. They also suggest that the main poverty-targeted social assistance schemes offer critical support for the extreme poor, but expanding both coverage and benefits is vital to shield all at-risk individuals. Targeted policies that balance immediate relief with long-term resilience-building are essential to addressing the challenges posed by escalating food prices.Publication Disentangling the Key Economic Channels through Which Infrastructure Affects Jobs(Washington, DC: World Bank, 2025-04-03)This paper takes stock of the literature on infrastructure and jobs published since the early 2000s, using a conceptual framework to identify the key channels through which different types of infrastructure impact jobs. Where relevant, it highlights the different approaches and findings in the cases of energy, digital, and transport infrastructure. Overall, the literature review provides strong evidence of infrastructure’s positive impact on employment, particularly for women. In the case of electricity, this impact arises from freeing time that would otherwise be spent on household tasks. Similarly, digital infrastructure, particularly mobile phone coverage, has demonstrated positive labor market effects, often driven by private sector investments rather than large public expenditures, which are typically required for other large-scale infrastructure projects. The evidence on structural transformation is also positive, with some notable exceptions, such as studies that find no significant impact on structural transformation in rural India in the cases of electricity and roads. Even with better market connections, remote areas may continue to lack economic opportunities, due to the absence of agglomeration economies and complementary inputs such as human capital. Accordingly, reducing transport costs alone may not be sufficient to drive economic transformation in rural areas. The spatial dimension of transformation is particularly relevant for transport, both internationally—by enhancing trade integration—and within countries, where economic development tends to drive firms and jobs toward urban centers, benefitting from economies scale and network effects. Turning to organizational transformation, evidence on skill bias in developing countries is more mixed than in developed countries and may vary considerably by context. Further research, especially on the possible reasons explaining the differences between developed and developing economies, is needed.

Publication Taking Stock of Economic Regulation of Power Utilities in the Developing World(World Bank, Washington, DC, 2018-05)The model of power sector reform that emerged during the 1990s placed considerable emphasis on the creation of an independent regulatory agency, with a strong orientation toward technically-driven tariff-setting procedures. Despite widespread uptake of regulation, implementation has proved to be challenging in the developing world. Regulators were seldom as independent as originally envisaged, with widespread divergence between the formal regulatory framework and the day-to-day practice of regulation. In practice, many developing countries operate with “advisory regulators” whose main role is to provide technical support to the ultimate political decision makers. Nevertheless, there is some evidence that regulation has had a positive performance impact, particularly where utilities are privatized and in middle-income settings. But the impact is more questionable in cases where regulation is primarily directed toward state-owned enterprises, which lack the commercial incentives to respond to regulatory instruments. On the choice of regulatory regimes, the ongoing debate between price cap and rate of return regulation suggests that the latter may be better suited to developing country environments where the priority is to provide predictable returns to support large capital investment programs. Furthermore, the advent of technological disruption in the power sector demands an adaptation of the way in which regulatory instruments are designed and applied. Regulators will need to pay closer attention to providing the right incentives for utilities to innovate and become more energy efficient, and for consumers to take economically grounded decisions on distributed generation. Finally, the literature leaves many important questions unanswered, such as how regulatory design affects regulatory effectiveness and the impact of tariff regulation on cost recovery.Publication Learning from Power Sector Reform(World Bank, Washington, DC, 2021-07-31)At the time of independence, in 1991, Ukraine had a monolithic state-run power sector. Its main concern was to transform the sector into a more efficient and competitive system that can be consistent with eventual European Union membership. A series of steps were taken in this direction - some unbundling of the sector; limited privatization; establishing a regulator; and creating a wholesale power market. Unfortunately, these reform steps did not achieve the reform objectives, and, at the time, there was no political consensus on the path forward. The changing regional political landscape, especially driven by the Crimea crisis, raised a fresh impetus for the reforms as the sector faced new concerns. Security of supply concerns, particularly over gas from Russia and limited access to high quality coal mines, were suddenly centerstage for a country where the inherited system had excess supply even at peak demand. Sector reforms were undertaken to align more closely with the second and third European Union energy packages. This case study follows Ukraine power sector’s reform process and presents lessons learned that can be useful for other developing countries.Publication Learning from Power Sector Reform(World Bank, Washington, DC, 2019-05)Pakistan's power sector underwent a substantial, if protracted, reform process. Beginning with an independent power producer program in 1994, the full unbundling of the national vertically integrated power and water utility, the Water and Power Development Authority, and the establishment of a regulatory entity, the National Electric Power Regulatory Authority, followed in 1997, paving the way for the eventual privatization of one major distribution utility, Karachi Electric, in 2005. Plans to privatize the remaining distribution utilities were shelved following the controversy surrounding the Karachi Electric transaction. A single buyer model has been in operation since the sector restructuring, with the Central Power Purchasing Agency fully separated from transmission and dispatch (the National Transmission and Dispatch Company) in June 2015. Despite these major steps, Pakistan has continued to suffer from inadequate capacity and other constraints, leading to large and frequent blackouts. At the heart of the impasse is the so-called "circular debt" crisis, whereby distribution utilities struggling to collect revenues and meet regulatory targets for transmission and distribution losses default on their payments to generators, and the sector is periodically bailed out by the government once losses accumulate to intolerable levels, at high cost to the exchequer. This dynamic has undermined incentives for utilities to improve their efficiency, while discouraging generators from investing in new capacity to address supply shortages. In the meantime, little has been done to accelerate access to electricity to the significant share of unserved population in rural areas.Publication Learning from Power Sector Reform(World Bank, Washington, DC, 2019-05)The Philippines power sector underwent a substantial and largely complete reform process. Following a severe shortage of supply in the late 1980s and the Asian Financial crisis of 1997, which made the dollar-denominated debt of the National Power Corporation extremely burdensome, the Electric Power Industry Reform Act was passed in 2001. This was intended to improve the quality of service and reduce power tariffs via the introduction of private participation and competition at the wholesale and retail levels. Although the implementation of the full reform program took longer than originally expected, the unwavering support given to the reform agenda by successive presidents of the country ensured that the planned steps had all been completed by 2013. At that time, retail competition and open access for consumers in Luzon and Visayas of more than one megawatt were introduced. The reform process was not impeded by complications that would have arisen if consumer subsidies had been endemic, but retail prices are even higher than might have been expected in the absence of subsidies, due to domestic taxation and the presence of some inefficiencies that have not yet been eliminated by the onset of competition.Publication Taking Stock of the Political Economy of Power Sector Reforms in Developing Countries(World Bank, Washington, DC, 2018-07)The power sector reform experiences of developing countries vary greatly. To help explain this from a political economy perspective, this paper reviews several dozen statistical analyses, multi-country case studies, and development practice publications. The frame of reference is the model of market-oriented reforms that became a global norm in the 1990s. Findings are organized in terms of the history, theory, motives, processes and outcomes of reforms. Market orientation emerged around the 1980s as part of a shift in economic theory and policy away from state control, and was expected to improve efficiency and investments. Reform advocates never took political economy issues into full consideration. Yet, policy makers have had sociopolitical as well as technical motives for reform, such as crisis response. International norms and competition for foreign investment and trade pulled governments to model reforms, while development partners pushed them as a condition of aid. Reform implementation has been characterized by strong tensions among different public and private interests. Concretely, 1990s model reforms were based on a logic of depoliticizing pricing and investment decisions; often placing policy makers in a conflict of interest situation. Thus, the political costs and risks of reform have often exceeded the benefits perceived by local decision makers, especially as reforms did not generally result in immediate benefits for citizens. In practice, incremental, inclusive processes may be better than quick and stealthy reforms that sidestep stakeholders' concerns. While there was limited evidence of efficacy at the time the reforms were implemented, ex post the outcomes of reforms are ambiguous, as improvements in some areas have been offset by negative results elsewhere. For increasing access to electricity and clean energy, 1990s model reforms may help, but they are neither necessary nor sufficient, nor did they focus on these objectives. In conclusion, the success or failure of policy prescriptions such as 1990s model reforms are contingent on dynamic, context-specific institutions as well as factors beyond the sector. More work is needed on integrated, flexible approaches to think and work politically in the sector, and to account for new technology and diverse sector development objectives.

However, the global economy appears to be settling at a low growth rate that will be insufficient to foster sustained economic development—with the possibility of further headwinds from heightened policy uncertainty and adverse trade policy shifts, geopolitical tensions, persistent inflation, and climate-related natural disasters. Against this backdrop, emerging market and developing economies are set to enter the second quarter of the twenty-first century with per capita incomes on a trajectory that implies substantially slower catch-up toward advanced-economy living standards than they previously experienced. Without course corrections, most low-income countries are unlikely to graduate to middle-income status by the middle of the century. Policy action at both global and national levels is needed to foster a more favorable external environment, enhance macroeconomic stability, reduce structural constraints, address the effects of climate change, and thus accelerate long-term growth and development.Publication Business Ready 2024(Washington, DC: World Bank, 2024-10-03)Business Ready (B-READY) is a new World Bank Group corporate flagship report that evaluates the business and investment climate worldwide. It replaces and improves upon the Doing Business project. B-READY provides a comprehensive data set and description of the factors that strengthen the private sector, not only by advancing the interests of individual firms but also by elevating the interests of workers, consumers, potential new enterprises, and the natural environment. This 2024 report introduces a new analytical framework that benchmarks economies based on three pillars: Regulatory Framework, Public Services, and Operational Efficiency. The analysis centers on 10 topics essential for private sector development that correspond to various stages of the life cycle of a firm. The report also offers insights into three cross-cutting themes that are relevant for modern economies: digital adoption, environmental sustainability, and gender. B-READY draws on a robust data collection process that includes specially tailored expert questionnaires and firm-level surveys. The 2024 report, which covers 50 economies, serves as the first in a series that will expand in geographical coverage and refine its methodology over time, supporting reform advocacy, policy guidance, and further analysis and research.Publication Digital Progress and Trends Report 2023(Washington, DC: World Bank, 2024-03-05)Digitalization is the transformational opportunity of our time. The digital sector has become a powerhouse of innovation, economic growth, and job creation. Value added in the IT services sector grew at 8 percent annually during 2000–22, nearly twice as fast as the global economy. Employment growth in IT services reached 7 percent annually, six times higher than total employment growth. The diffusion and adoption of digital technologies are just as critical as their invention. Digital uptake has accelerated since the COVID-19 pandemic, with 1.5 billion new internet users added from 2018 to 2022. The share of firms investing in digital solutions around the world has more than doubled from 2020 to 2022. Low-income countries, vulnerable populations, and small firms, however, have been falling behind, while transformative digital innovations such as artificial intelligence (AI) have been accelerating in higher-income countries. Although more than 90 percent of the population in high-income countries was online in 2022, only one in four people in low-income countries used the internet, and the speed of their connection was typically only a small fraction of that in wealthier countries. As businesses in technologically advanced countries integrate generative AI into their products and services, less than half of the businesses in many low- and middle-income countries have an internet connection. The growing digital divide is exacerbating the poverty and productivity gaps between richer and poorer economies. The Digital Progress and Trends Report series will track global digitalization progress and highlight policy trends, debates, and implications for low- and middle-income countries. The series adds to the global efforts to study the progress and trends of digitalization in two main ways: · By compiling, curating, and analyzing data from diverse sources to present a comprehensive picture of digitalization in low- and middle-income countries, including in-depth analyses on understudied topics. · By developing insights on policy opportunities, challenges, and debates and reflecting the perspectives of various stakeholders and the World Bank’s operational experiences. This report, the first in the series, aims to inform evidence-based policy making and motivate action among internal and external audiences and stakeholders. The report will bring global attention to high-performing countries that have valuable experience to share as well as to areas where efforts will need to be redoubled.
