Abstract
Heterogeneity of public utility services is common in developing countries. In a "high-level" equilibrium, the quality of utility services is high, consumer willingness to pay for services is high, the utility is well funded and staff well paid in order to induce high quality of performance. In a "low-level" equilibrium the opposite is the case. Which alternative occurs depends on both the quality of utility management, and public perceptions about service quality. If a utility administration has the potential to offer high-quality service, and the public is aware of this, high-quality equilibrium also requires the public s service payments to be high enough to fund the needed pay incentives for the utility staff. When the public lack knowledge about the utility administration s quality, the public s initial beliefs about the utility administration s quality also will influence their willingness to make adequate service payments for a high-quality equilibrium. This paper shows that, with low confidence, only a low-level equilibrium may exist; while with higher initial confidence, a high-level equilibrium become possible. "Intermediate" (in between the low- and high-level) outcomes also can occur in early periods, with "high-level" outcomes later on.

Publication Climate and Social Sustainability in Fragility, Conflict, and Violence Contexts(Washington, DC: World Bank, 2026-01-07)Climate change is widely recognized as a driver of violent conflict, but its broader social effects remain less understood. Ignoring these dimensions risks a vicious cycle where climate policies might undermine socially just adaptation. Evidence is still limited on how climate shocks influence political participation, trust, or migration. This paper helps fill that gap by examining links between climate change, conflict, and social sustainability, with a focus on inclusion, resilience, cohesion, and legitimacy. Using secondary data from 2019–24, the study applies simple correlation-based methods to test three hypotheses on the nature, severity, and composition of these associations. The analysis combines multiple climate impact measures, new conflict classifications, recent social sustainability frameworks, and controls for population and geography. The results reveal strong correlations—not causation—between climate events and contexts of fragility, conflict, and violence. Climate impacts are most pronounced in both national and subnational conflict settings. The study also finds robust links between fragility, conflict, and violence and low levels of social sustainability, reflecting its role as both a driver and consequence of conflict. Some dimensions—such as violent events and insecurity—appear weaker in areas most affected by climate shocks. Two of the hypotheses are supported, and one remains inconclusive.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 Institutional Capacity for Policy Implementation: An Analytical Framework(Washington, DC: World Bank, 2026-01-07)State capacity is an important prerequisite for policy implementation, yet at the country level it is difficult to measure, assess, and reform. This paper proposes a focus on institutional capacity: the ability of public institutions to implement the specific policy mandates for which they are responsible. Based on a review of existing literature, the paper defines the different dimensions that compose institutional capacity and groups them into two cross-cutting categories: organizational dimensions (personnel, financial resources, information systems, and management practices) and governance dimensions (transparency, independence, and accountability). The paper proposes measures for organizational and governance dimensions using existing data, shows intra-institutional variation of these measures within countries, and discusses how new data could be collected for better measurement of these concepts. Finally, the paper illustrates how the framework can be used to diagnose the sources of common problems related to weak policy implementation.Publication South Africa’s Fragmented Cities: The Unequal Burden of Labor Market Frictions(Washington, DC: World Bank, 2026-01-08)Using high-resolution administrative, census, and satellite data, this paper shows that South African cities are characterized by spatial mismatches between where people live and where jobs are located, relative to 20 global peers. Areas within 5 kilometers of commercial centers have 9,300 fewer residents per square kilometer than expected, which is 60 percent below the global median. Poor, dense neighborhoods are most affected. In Johannesburg, a 10-percentile increase in distance from the nearest business hub corresponds to a 3.7-percentile drop in asset wealth (a proxy of household wellbeing) and 4.9-percentile drop in employment. In Cape Town, the declines are 4.0 and 3.7 percentiles, respectively. Employment is 87 percent lower in the poorest decile than the richest in Johannesburg and 61 percent lower in Cape Town. These findings suggest that South Africa’s spatial organization of people and economic activity constrains agglomeration and reinforces inequality. This methodology provides a scalable and standardized data-driven framework to analyze spatial accessibility and agglomeration frictions in complex, data-constrained urban systems.Publication Investment in Emerging and Developing Economies(Washington, DC: World Bank, 2026-01-07)The world faces a pressing challenge to meet key development objectives amid slowing growth and rising macroeconomic and geopolitical risks. With the number of job seekers rising rapidly, infrastructure shortfalls continuing to be large, and climate costs mounting, the case for a significant investment push has never been stronger. Yet the capacity to respond in many emerging markets and developing economies has eroded. Since the global financial crisis, investment growth has slowed to about half its pace in the 2000s, with both public and private investment weakening. Foreign direct investment inflows—a critical source of capital, technology, and managerial know-how—have also fallen sharply and become increasingly concentrated, leaving low-income countries with only a marginal share. The risks of further retrenchment are significant, as trade tensions, policy uncertainty, and elevated debt levels continue to weigh on investment. Reigniting momentum will require ambitious domestic reforms to strengthen institutions, rebuild macro-fiscal stability, and deepen trade and investment integration—the foundations of a supportive business climate. At the same time, international cooperation is indispensable. A renewed commitment to a predictable system of cross-border trade and investment flows, combined with scaled-up financial support and sustained technical assistance, is essential to help emerging markets and developing economies—especially low-income countries and economies in fragile and conflict situations—bridge financing gaps and implement the domestic reforms needed to restore investment as an engine of growth, jobs, and development.

Publication Markets and Manipulation(World Bank, Washington, DC, 2016-04)There is a growing appreciation in economics that people have emotional vulnerabilities, commitments to social norms, and systematic irrationalities, which impact their decision making and choice in the marketplace. The flip side of this is that human beings are susceptible to being manipulated by unscrupulous agents who are single-minded about marketing their services and wares. This paper reviews George Akerlof and Robert Shiller's book, Phishing for Phools: The Economics of Manipulation and Deception, alongside other writings in the field, and discusses how this research agenda can be taken forward. The paper shows how this new research can shed light on the ubiquity of corruption in so many societies, and proposes ideas for controlling corruption.Publication Simulating the Effects of Supply and Demand Elasticities on Political-Economic Equilibrium(World Bank, Washington, DC, 2008-06)Wallace's (1962) pioneering study brought to agricultural economics a focus on the role of supply and demand elasticity's in determining the efficiency with which agricultural policy transfers income among interest groups. His discussion provides key insights into what I call the "consequences of policy" side of current models of political economy. Becker's (1983) and Grossman and Helpman's (1994) models, both famously seminal in the political economy literature, have such "consequences" sides, and therefore when agricultural policy is examined in their models' frameworks, market elasticity's play key roles. These two models have also "causes of policy" sides, which describe interest groups' abilities to create political pressure. Wallace aim is to provide a theoretical review and exposition of the effects of elasticity's on redistribution efficiency, and in turn on distortional policies in political economic equilibrium. He demonstrates how models of actual political economies might be built and used to derive theoretical predictions about how market elasticity's affect policy and income transfers. Applying similar models to examine real world political economies can provide testable hypotheses about how market parameters affect distortional policies.Publication Botswana's Infrastructure : A Continental Perspective(2011-11-01)Infrastructure made a net contribution of just over two percentage points to Botswana's improved per capita growth performance in recent years. Raising the country s infrastructure endowment to that of the region's middle-income countries could boost annual growth by about 1.2 percentage points. Botswana has made significant infrastructure progress in recent years, spanning the transport, water and sanitation, power, and mobile telephony sectors. But the country still faces a number of important infrastructure challenges. The most pressing is in the power sector, where the country is economically and financially exposed to a lack of generation capacity and insufficient power supply, leaving the economy vulnerable to power price shocks and load shedding. Botswana's international transport connections and Internet connectivity also lag behind those of comparable countries. Botswana's overall resource envelope of $800 million per year surpasses its $785 million needs estimate. Nevertheless, it loses $68 million a year to inefficiencies and faces a funding gap of $305 million per year, entirely in the power sector, traceable to the quality of spending decisions. Botswana will be in a good position to meet its infrastructure goals if it can reduce inefficiencies, increase public-sector receipts, and attract more public funding.Publication Private Cities(Washington, DC: World Bank, 2022-02-10)Institutional weaknesses limit the capacity of local governments to support efficient urbanization in developing countries. They also lead to the emergence of large developers with the clout to build entire cities. This paper analyzes the urbanization process when local governments are weak and large developers are powerful. Results from a non-cooperative game setting with minimal assumptions show that multiple equilibria can emerge depending on key institutional parameters of the model and the nature of the game, but all of them are inefficient. In this simple setting, increasing the capacity of the local government may not lead to better outcomes, because it may crowd out urban land development by the more effective private investor. Subsidizing the large investor can ensure efficiency, but it makes the rest of society worse off. Selling the rights to the city can be Pareto efficient, but only provided that the price at which the rights are sold are sufficiently high. However, more analytical and empirical work is needed before these analyses can be deemed relevant in practice. Competition among jurisdictions, time consistency challenges, and the social implications of private cities deserve special attention.Publication Equilibrium Parallel Import Policies and International Market Structure(2011-09-01)In a North-South vertically differentiated duopoly, the analysis in this paper derives equilibrium government policies towards parallel imports. By incorporating strategic interaction at the policy-setting stage and the product market, the model sheds new light on (i) the effects of parallel import policies on pricing behavior of firms and (ii) the interdependence of national parallel import policies. If demand asymmetry across countries is sufficiently large, the North forbids parallel imports to ensure its firm sells in the South thereby generating international price discrimination -- the South's most preferred market outcome -- as the equilibrium. When demand structures are relatively similar across countries, the North permits parallel imports and uniform pricing -- its most preferred market outcome -- obtains.

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 Long COVID(World Bank, Washington, DC, 2023-02)This paper examines the welfare impacts of the COVID-19 pandemic, using harmonized data from 343 high-frequency phone surveys conducted in 80 economies during 2020 and 2021, representing more than 2.5 billion people. The analysis focuses on the scarring effects of the initial losses of employment and income by examining their evolution over time across and within countries, as restrictions on mobility and economic activity were introduced and then gradually relaxed. The employment and welfare outcomes of some groups that were impacted to a greater degree initially—including women, informal workers, and those with less education—have been improving at a slower pace. The social protection response in lower-income economies was largely insufficient to protect households from the pandemic shock. Unmitigated welfare losses, as seen for example from the large share of households indicating income losses well into 2021, are highly correlated with food insecurity, which likely led some households to sell physical assets and deplete their savings. Without proper remediation, the uneven welfare impacts associated with COVID-19 may be amplified over the medium to long term, leading to future increases in poverty and inequality.Publication Slovak Republic--Joining the EU : A Development Policy Review(Washington, DC, 2003-06)The Slovak Republic's external current account and fiscal deficits (net of privatization receipts) are unsustainably high (at about 8 percent of GDP in 2002), despite some recent declines. With a capital account surplus of perhaps 20 percent of GDP this year, the Slovak Republic may not find it particularly difficult to finance these deficits, but this favorable situation will not last. Furthermore, through its impact on the real exchange rate, this policy mix is undermining the employability of large segments of the population (particularly those with low skill levels) and will ultimately choke growth (projected at 4 percent for 2002). While much policy attention has gone to stimulating investment, future growth will also depend on raising the employment rate, currently one of the lowest among the Central and East European Countries (CEECs). This report lays out the broad thrust of a policy strategy to bolster the recovery and bring the economy towards convergence with the EU. This strategy consists of three key elements: (a) Continued trade, finance, and enterprise reform to complete the structural transformation of the economy and align it with the EU framework (b) Fiscal consolidation, focusing on cutting back expenditure and stabilizing revenues, while redirecting revenue and expenditure policies to become more fully supportive of growth and employment objectives (c) Labor market reform, directed at enhancing labor market flexibility by relaxing legal provisions on working arrangements (such as part-time work, self-employment, and fixed term contracts), by decentralizing collective bargaining, and discarding the minimum wage as an instrument of incomes policy, and by reforming the social assistance system. The ultimate success of the policy reforms outlined in this report will depend to a great extent on the government's capacity to strengthen the institutional framework in which those policies are conceived, decided upon, and executed. Three priorities have been highlighted: (i) the reform of public expenditure management systems and practices needed to support a growth-oriented fiscal strategy; (ii) the consolidation of the recent decentralization moves as a prerequisite for further devolution, and (iii) a much overdue overhaul of the judiciary system.Publication Kosovo Country Economic Memorandum, November 2021(World Bank, Washington, DC, 2021-11)Foreign direct investment (FDI) can bring many benefits to Kosovo’s economy, creating more and better jobs and spurring greater and more resilient economic growth. Many transition economies have used FDI as a pillar of their structural transformation and modernization efforts. The small number of firms in Kosovo that include FDI are more productive than other firms, and they were more resilient in the wake of the Coronavirus disease 2019 (COVID-19) economic recession. In Kosovo, FDI inflows have been concentrated in sectors that provide limited potential for productivity spillovers and benefits to the domestic economy. Kosovo needs to adopt proactive policies to strengthen its investment competitiveness and investor outreach in order to unlock more and higher-quality FDI. This note presents an ambitious reform agenda that can help improve Kosovo’s investment competitiveness and investor outreach. It presents a step-by-step reform program for unlocking the full potential of FDI for economic growth and job creation in Kosovo that the government can implement in the short to medium term. The note is structured in three sections. The first section looks at Kosovo’s FDI performance and assesses the quantity and quality of the FDI attracted so far. The second section benchmarks Kosovo’s locational FDI determinants, considering a set of macroeconomic and microeconomic indicators for its overall FDI competitiveness. The third section combines the findings from the first two sections with an in-depth assessment of Kosovo’s policy, legal, and institutional framework for investment to present a targeted reform agenda and policy action plan to help attract more and higher-quality investments to Kosovo.Publication Absolute and Relative Poverty Measurement(World Bank, Washington, DC, 2022-04)This paper reviews the debate opposing the absolute and relative approaches to monetary poverty measurement. The arguments for combining both approaches into a single “overall” monetary poverty measure are introduced. The most salient proposals of hybrid poverty lines are presented. Then, the reasons why specific poverty indices may be required when a hybrid line is used are discussed. The class of hierarchical poverty indices is described, focusing in particular on the hierarchical headcount ratio.
