Abstract
This paper investigates cross-sectoral productivity differentials in South African industry and their distributional consequences. The analysis shows that typically, traded sectors have experienced low productivity growth over the past decade, while skill intensive service sectors have had significant productivity growth. This is the inverse of the traditional Balassa-Samuelson sectoral transformation hypothesis, where high wages in high-productivity traded sectors increase wages throughout the economy, thus increasing prices on non-traded goods and revaluing the country's real exchange rate. Instead, the higher productivity of non-traded sectors experienced in South Africa induces a devaluation of the real exchange rate and a contraction of the traded sectors. The results of the estimation show evidence of this "inverse" Balassa-Samuelson effect for agriculture and manufacturing and in particular mining. This "inverse" Balassa-Samuelson effect has important distributional consequences: the high-productivity sectors are associated with cheaper goods and services for wealthy households. This in turn burdens poor households, which are more dependent on traded goods, with higher prices, which are a consequence of low productivity and high markups.

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 Agricultural Distortions, Poverty, and Inequality in South Africa(World Bank, Washington, DC, 2009-06)South Africa has rapidly reduced trade barriers since the end of Apartheid, yet agricultural production and exports have remained sluggish. Also, poverty and unemployment have risen and become increasingly concentrated in rural areas. This paper examines the extent to which remaining price distortions, both domestic and foreign, are contributing to the underperformance of the agricultural sector vis-a-vis the rest of the economy. The author draws on a computable general equilibrium (CGE) and micro-simulation model of South Africa that is linked to the results of a global trade model. This framework is used to examine the effects of eliminating global and domestic price distortions. Model results indicate that South Africa's agricultural sector currently benefits from global price distortions, and that removing these will create more jobs for lower-skilled workers, thereby reducing income inequality and poverty. The author also fined that South Africa's own policies are biased against agriculture and that removing domestic distortions will raise agricultural production. Job losses in nonagricultural sectors will be outweighed by job creation in agriculture, such that overall employment rises and poverty falls. Overall, the findings suggest that South Africa's own policies are more damaging to its welfare, poverty and inequality than distortionary policies in the rest of the world. Existing national price distortions may thus explain some of the poor performance of South Africa's agricultural sector and rural development.Publication What Happens When a Country Does Not Adjust to Terms of Trade Shocks? The Case of Oil-Rich Gabon(World Bank, Washington, D.C., 2004-09-01)Gabon is currently one of the richest countries in Sub-Saharan Africa, having a GDP per capita of close to $4,000, and is characterized by a stable political climate and rich forestry and mineral resources, as well as a small population. Oil is the key economic sector, accounting for half of GDP and more than two-thirds of revenue. Discovered in the 1970s, oil windfalls have delivered spectacular wealth and financed public expenditure over two decades. However, the oil boom has led to the Dutch disease and the shrinkage of the industrial and agricultural sectors of the economy due to the appreciation of the exchange rate and the movement of capital to the oil sector. But with output projections suggesting that oil will be depleted within the next 10 to 15 years, there are growing pressures on the policymakers to take actions to diversify production. While Gabon's membership in the Central African economic and monetary union means that it benefits from the macroeconomic stability from a common external trade and fixed exchange rate regime pegged to the euro, it relinquishes independence in the policy response to shocks. An analysis using a quantitative methodology to decompose responses to shocks shows that Gabon's adjustment to adverse movements in the terms and trade from 1980 to 2000 was considerably weak in terms of three performance indicators-import intensity, economic compression, and nonoil export promotion. While the economy's growth rate was respectable, policymakers postponed adjustment by resorting to considerable borrowing during this period. While there was some decrease in import intensity from 1987 to 1990 and 1996 to 2000, as well as slight non-oil export diversification from 1996 to 2000, the government borrowed from commercial banks and donors, causing its external debt/GDP ratio to increase from 30 percent of GDP in 1970-76 to 80 percent in 1999. To pay the debt service, it currently has to maintain large primary surpluses. Only since 1996 has there been significant fiscal retrenchment and a freezing of government wages.Publication Scaling up Aid or Scaling down : The Global Economic Crisis and Rwanda’s MDGs(2009-06-01)Rwanda is not on track to achieve most of the Millennium Development Goals at a time when hopes for scaled-up aid are mixed with concerns that, in the context of the global economic crisis, aid instead will be scaled down. This paper analyzes the effects of alternative scenarios for grant aid, government spending allocations (between infrastructure, agriculture, and human development), and government efficiency. The authors use an economy-wide model for development strategy analysis, Maquette for Millennium Development Goal Simulations. Under a plausible scenario for increased aid, annual growth in gross domestic product increases by as much as 0.6 percentage points relative to a baseline with a growth rate of 6 percent; by 2020, the headcount poverty rate declines to 32 percent, 3 percentage points lower than for the baseline. A plausible scenario for reduced aid leads to a symmetric growth reduction but a more pronounced increase in poverty, at 40 percent in 2020. When aid increases, the most positive growth and poverty reduction impacts occur if spending increases are allocated to infrastructure and agriculture; progress in human health and education is significant but weaker than if additional spending is focused on these areas. Given synergies and diminishing marginal returns from expansion in a limited area, the scenarios that may appear most attractive and politically feasible have a broad and balanced expansion across government functions, promoting both growth and human development.Publication Lobbying, Counterlobbying, and the Structure of Tariff Protection in Poor and Rich Countries(Washington, DC: World Bank, 2004-09)A political economy model of protection is used to determine endogenously the intersectoral patterns of protection. Three propositions are derived that are consistent with the stylized patterns of tariff protection in rich and poor countries: Nominal protection rates escalate with the degree of processing, protection is higher on average in poor countries, and rich countries protect agriculture relatively more than they protect manufacturing, whereas poor countries do the reverse. Numerical simulations for archetypal rich and poor economies confirm that the endogenously determined structure of protection is broadly consistent with observed patterns of protection.Publication An Assessment of the Investment Climate in South Africa(Washington, DC: World Bank, 2007)The objective of the South Africa Investment Climate Assessment (ICA) is to evaluate the investment climate in South Africa in all its operational dimensions and to promote policies to strengthen the private sector. The investment climate is made up of the many location-specific factors that shape opportunities and incentives for firms to invest productively, create jobs, and expand. These factors include macroeconomic and regulatory policies, the security of property rights and the rule of law, and the quality of supporting institutions such as physical and financial infrastructure. The main source of information for the ICA is a survey of over 800 formal private enterprises. The survey includes data on firm productivity, the cost of doing business, the regulatory environment, the labor market, the financial sector, the trade regime, and levels of investment. The analysis links business environment constraints to firm-level costs and productivity. Also, the investment climate and performance of firms in South Africa can be compared with those of firms in the more than 70 low- and middle income countries in which Investment Climate Surveys (ICSs) have been conducted.

Publication Global Economic Prospects, June 2025(Washington, DC: World Bank, 2025-06-10)The global economy is facing another substantial headwind, emanating largely from an increase in trade tensions and heightened global policy uncertainty. For emerging market and developing economies (EMDEs), the ability to boost job creation and reduce extreme poverty has declined. Key downside risks include a further escalation of trade barriers and continued policy uncertainty. These challenges are exacerbated by subdued foreign direct investment into EMDEs. Global cooperation is needed to restore a more stable international trade environment and scale up support for vulnerable countries grappling with conflict, debt burdens, and climate change. Domestic policy action is also critical to contain inflation risks and strengthen fiscal resilience. To accelerate job creation and long-term growth, structural reforms must focus on raising institutional quality, attracting private investment, and strengthening human capital and labor markets. Countries in fragile and conflict situations face daunting development challenges that will require tailored domestic policy reforms and well-coordinated multilateral support.Publication National Development Financial Institutions(World Bank, Washington, DC, 2021-10-08)In recent years, there has been renewed interest in providing countercyclical lending and sustainable development financing through national development financial institutions (NDFIs). While NDFIs are often a feasible solution for addressing development needs and closing financing gaps, they are not always the best solution, and their setup and structure need to be tailored to the country’s needs. It is important that prior to setting up a new NDFI or increasing the scope of operations of the existing ones, governments consider all available public policy interventions as well as options for private capital involvement to address unmet financing needs of the private sector. NDFIs will likely see strong demand for their interventions in a post- Coronavirus disease 2019 (COVID-19) recovery phase. This calls for enhanced NDFI efficiency and effectiveness. To maximize the net benefits of NDFIs and ensure their financial sustainability, NDFIs should be effectively managed and properly supervised. NDFIs have been important actors in the implementation of countercyclical finance in response to the COVID-19 pandemic and have helped mitigate a credit crunch. During the COVID-19 pandemic, governments have taken on large balance-sheet risks to support credit growth, in many cases using NDFIs as administrators of public anti-crisis programs.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 Towards a National Jobs Strategy in Kuwait(World Bank, Washington, DC, 2022)This report is one of the main deliverables outlined in the legal arrangement of September 10, 2019, between the General Secretariat of the Supreme Council for Planning and Development (GS-SCPD) in Kuwait and the World Bank. A separate overview report is also available. The social contract in Kuwait is at risk. Kuwaiti citizens are used to the state providing public sector jobs, free education, free healthcare, and subsidized fuel to all citizens. These benefits have been bought and paid for using Kuwait’s oil revenues, however, the sustainability of the social contract has been questioned by three mutually reinforcing challenges. First, oil demand is projected to steadily decline the next few decades. This decline is partly the result of changing consumer preferences away from carbon-based fuel sources, and partly the result of increasingly cost-effective alternative energy sources becoming available. Second, with mounting fiscal deficits, the size of the wage bill for the government is a growing concern. Third, the needs in the labor market will continue to grow as Kuwait’s population is young and growing. Central to these structural challenges are challenges to Kuwait’s labor market. A growing number of young Kuwaitis are entering the labor market with high expectations of well-paid, secure, public sector jobs. In the private sector, employers are dependent on low-cost and largely unskilled foreign workers. The 2019 COVID-19 global pandemic, which has led to an oil price crisis and a global economic slowdown, has intensified the debate surrounding jobs challenges in Kuwait. These jobs challenges need to be addressed to ensure the sustainability of the economic growth model and avoid major social disruption. The government has asked The World Bank for assistance to formulate a National Jobs Strategy to help confront these challenges, based on evidence and best practices. Reforms are recommended in four areas, or pillars: (i) make the public sector more sustainable, (ii) improve human capital, (iii) support private sector growth, and (iv) build a social protection system. In addition, the jobs strategy covers two cross-cutting themes: behavioral economics, and monitoring and evaluation, also embedded in the four pillars. This introduction briefly explains the critical challenges facing Kuwait that require substantial changes in policy. The subsequent sections analyze the major issues of these four topics, with recommendations for policy change to improve sustainability and enhance incomes.Publication Carbon Pricing in the Power Sector(Washington, DC: World Bank, 2024-09-09)The number of countries that have announced some type of commitment to net zero emissions has increased very rapidly in recent years, from five in 2018 to over 145 in 2023. Middle and low-income countries must therefore consider policies to both grow and decarbonize their power sectors. A growing number of them are considering carbon pricing instruments (CPIs). However, the path to implementing carbon pricing is fraught with challenges, including financing obstacles, the urgent need to boost supply, and social priorities different from those of more advanced economies with more carbon pricing experience. This report delves deep into the power sector value chain dynamics, demonstrating how well-designed carbon pricing instruments can be instrumental in helping countries reach their decarbonization goals. Focusing on how decisions are made in diverse power sector models in several developing countries, this report establishes that the CPI must be carefully positioned at the right regulation point in the power sector’s value chain—rather than merely adding a burden for the sector. Getting it right can influence everything from power generation options to investment decisions and customers’ behaviors.
