Abstract
The behavior of commodities is critical for developing and developed countries alike. This paper contributes to the empirical evidence on the co-movement and determinants of commodity prices. Using nonstationary panel methods, the authors document a statistically significant degree of co-movement due to a common factor. Within a Factor Augmented VAR approach, real interest rate and uncertainty, as postulated by a simple asset pricing model, are both found to be negatively related to this common factor. This evidence is robust to the inclusion of demand and supply shocks, which both positively impact on co-movement of commodity prices.

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 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 The Evolution of Local Participatory Democracy in Nepal(Washington, DC: World Bank, 2025-11-05)Nepal is, according to its constitution, among the world’s most decentralized countries, with a long and complex tradition of local-level public participation. This paper traces the evolution of Nepal’s modern participatory institutions, examining the extent to which they are “induced” by external interventions versus being “organically” rooted in indigenous practices. The paper identifies three broad phases: an initial focus on participation in project implementation; a subsequent phase that expanded citizen engagement; and a third phase of citizen empowerment, culminating in the 2015 federal constitution, which granted unprecedented local autonomy. The analysis yields five key findings. First, over the past 50 years, successive reforms have progressively expanded opportunities for citizens to influence local decision-making. Second, these reforms have integrated traditional participatory mechanisms into formal institutions of local government. Third, although central-level initiatives exist, most participatory platforms continue to operate at the local level. Fourth, the federal constitution has created a new landscape of local democracy, embedding autonomy and accountability. Fifth, although they are still valued in many ethnic and territorial communities, traditional participatory practices are gradually disappearing. The paper concludes by offering policy recommendations to help donor agencies and governments strengthen Nepal’s democratic trajectory. It argues that effective interventions should build on Nepal’s deep participatory traditions while recognizing the constitutional reality of far-reaching local autonomy.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 Closing the Gender Gap in Entrepreneurship: Overcoming Challenges in Law and Practice for Female Entrepreneurs(Washington, DC: World Bank, 2026-01-07)Despite significant strides toward gender equality, women around the world continue to encounter systemic obstacles that hinder their entrepreneurial success. This paper systematically reviews the literature on the barriers female entrepreneurs face and the solutions proposed to overcome these challenges. It discusses institutional factors, financial factors, human capital factors, and social and cultural factors. The literature overview is complemented by a series of stylized facts that illustrate how overcoming some of these existing barriers is correlated with improved women’s entrepreneurship and female labor force participation, drawing on the World Bank’s Women, Business and the Law database as well as the World Bank’s Enterprise Surveys. The findings underscore the need for creating an enabling environment where women can thrive as entrepreneurs.

Publication South Africa Economic Update : Focus on Export Competitiveness(Washington, DC, 2014)In its National Development Plan 2030 and its New Growth Path (2011), South Africa identifies the export sector as an engine for faster, more inclusive, and job-intensive growth. The National Development Plan is targeting export volume growth of 6 percent a year, to achieve an annual increase in real Gross Domestic Product, or GDP growth of about 5.5 percent and to help generate 11 million new jobs by 2030. Despite successes in some subsectors, South Africa will need to greatly improve its export performance to meet these targets. The report highlights opportunities for growth, particularly with Sub-Saharan Africa being the largest market for non-mineral exports. It also explores strategic directions that can ignite export growth and help South Africa realize its goals of creating jobs and reducing poverty and inequality.Publication Thailand Economic Monitor, April 2011(World Bank, Bangkok, 2011-04)The pace of economic activity is gradually returning to pre-crisis levels. After a roller-coaster of sharp drops, vigorous rebounds and mild contractions, Gross Domestic Product (GDP) was up 4.8 percent in the last quarter of 2010 on a seasonally-adjusted annualized (SAAR) basis, closer to pre-crisis, normal levels. For 2010 as a whole, GDP expanded by 7.8 percent from 2009. Growth was broad-based, with significant contributions from external and domestic demands. Thailand's economy is one of the most energy intensive in the region because of the large (and growing) share of energy-intensive manufacturing in the economy and high proportion of cargo transported by trucks. Thailand can reduce its vulnerability to oil price shocks by raising fuel standards, improving tax incentives for conservation and relying more on rail for cargo transport.Publication Thailand Economic Monitor, November 2010(Washington, DC, 2010-11)Growth has slowed down since the second quarter, but exceeded expectations. Considering the 1) political turmoil; 2) robust growth during the rebound; and 3) slowdown in advanced economies, the Thai economy was expected to contract by more than it did in the second and third quarters. The output of the manufacturing sector expanded in the second quarter, led by still-growing exports and robust private consumption. Demand indeed appears to have been higher than production, as some orders had to be filled by drawing down on inventories. However, a sharp contraction in tourism led Gross Domestic product (GDP) overall to contract in the quarter. The FY10 fiscal deficit was much smaller than initially feared when the budget was proposed. The budget for FY10 was prepared at the trough of the global financial crisis in February 2009 and anticipated only 1.35 trillion baht in revenues. Inflation levels have been low and stable but persistent increases in food prices could pose risks. Overall, slower growth in advanced economies will translate into lower GDP growth Thailand for the next two to three years. Notwithstanding a deceleration in the second half because of the waning global inventory cycle, year-on-year growth in 2010 is expected at 7.5 percent due to the low base of 2009 and the strong first half. Quarter-to-quarter growth will pick up modestly in 2011 to average over 4 percent, but the relatively high base in 2010 results in a year-on-year growth rate of 3.2 percent for 2011.Publication Philippines Quarterly Update, June 2010(Washington, DC, 2010-06)The Philippines economy posted robust growth in early 2010, in part due to large one-off factors. As did many countries in the region, the Philippines benefited from a strong rebound in global trade. Manufacturing and investment activity expanded briskly as a result. Private consumption continued to expand, as consumer confidence improved. Growth also benefited from election-related spending. Expansionary (and now pro-cyclical) fiscal policy continued to support growth. Despite a withdrawal of liquidity-enhancing measures and a stronger peso, a closing output gap meant that monetary policy remained accommodative. A World Bank study of Philippines migration pattern during the global recession reveals that deployment of overseas foreign workers (OFWs) actually accelerated during the crisis. Partly this reflected the fact that the top OFW destinations were not as affected as the rest of the world. The most affected OFWs were males, production workers (especially construction workers) and new hires. By contrast, females, services workers, seafarers and rehires proved resilient to the crisis or even benefited from it. Globally, less tolerance towards weak public finances is expected, raising the need to introduce a credible medium-term fiscal consolidation plan for the Philippines. Running a pro-cyclical fiscal policy with relatively high debt and limited fiscal space-as undertaken in the first-half of 2010-raises risks and should be reverted. Credibility towards such a goal could be achieved, for example, by designing a comprehensive multi-year reform package. As the output gap closes, the accommodative monetary policy introduced in 2008 would need to be gradually unwound, starting by reaching a broadly neutral stance in 2010. An increase in policy rates currently negative or slightly positive could achieve such a goal.Publication Philippines Quarterly Update, December 2011(World Bank, Pasig City, Philippines, 2011-12)After a strong rebound in 2010, Philippine economic growth slowed by more than half to 3.6 percent in the first three quarters of 2011. Slower third quarter (Q3) growth of 3.2 percent was the result of significant contractions in exports and public investment. The contraction in exports largely reflected weaker demand in advanced economies while public investments continued to shrink in part because of measures to improve accountability of public spending. On the production side, industrial and agricultural activities were sluggish, leaving the services sector to buoy growth. To improve growth outcome in the remainder of the year, the government announced a PHP 72 billion (about 0.7 percent of GDP) disbursement acceleration plan to ensure that budgeted items are spent by year end. After a strong rebound in 2010, Philippine economic growth slowed by more than half to 3.6 percent in the first three quarters of 2011, bringing year to date growth below the government's revised target of 4.5 to 5.5 percent for 2011. Q3 growth of 3.2 percent was driven by private consumption and inventory build-up, which grew by 7.1 and 147.7 percent respectively. The country's slower expansion places it behind its neighbors with Indonesia, Vietnam, and Singapore growing above 6 percent, Malaysia at 5.8 percent, and Thailand, which was devastated by massive flooding in recent months, at 3.5 percent.

Publication Direct and Indirect Impacts of Transport Mobility on Access to Jobs: Evidence from South Africa(Washington, DC: World Bank, 2025-11-12)Access to jobs is essential for economic growth. In Africa, unemployment rates are notably high. This paper reexamines the relationship between transport mobility and labor market outcomes, with a particular focus on the direct and indirect effects of transport connectivity. As predicted by theory, wages are influenced by the level of commuting deterrence. Generally, higher earnings are associated with longer commute times and/or higher commuting costs. Local accessibility is also important, especially for individuals with time constraints. Both direct and indirect impacts are found to be significant in South Africa, where job accessibility has been challenging since the end of apartheid. For the direct impact, the wage elasticity associated with commuting costs is significant. Returns on commute are particularly high for women. Local accessibility to socioeconomic facilities, such as shops and health services, is also found to have a significant impact, consistent with the concept of mobility of care. To enhance employment, therefore, it is crucial to connect people not only to job locations but also to various socioeconomic points of interest, such as markets and hospitals, in an integrated manner. This integration will enable individuals to spend more time working and commuting longer distances.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 Continental Drying: A Threat to Our Common Future(Washington, DC: World Bank, 2025-11-04)Grounded in new evidence from satellite data, “Continental Drying: A Threat to Our Common Future” presents the first global assessment of freshwater reserves over the past two decades. The findings expose an alarming trend of “continental drying,” a persistent long-term decline in freshwater availability across vast landmasses. Not only are droughts and deluges becoming more unpredictable, but the total amount of freshwater available for use has also significantly declined. Continental drying, driven by global warming, worsening droughts, and unsustainable water and land use, is a silent but accelerating crisis—largely unknown to the public—that reshapes the global water narrative. Continental drying raises profound risks. This report reveals new empirical evidence showing how freshwater depletion leads to major job losses, reduced incomes, wildfires, and biodiversity threats. In the long term, the combined effects of drying and warming could push societies toward a tipping point where damage accelerates rapidly and adaptation becomes increasingly difficult. Against the backdrop of continental drying, global water consumption rose by 25 percent between 2000 and 2019, with about a third of this increase occurring in regions already experiencing drying. Compounding the pressure, a substantial share of water use in drying regions remains inefficient. Continental Drying identifies hot spots where rising demand and declining supply converge and explores where and how water savings can be realized. This report recommends a three-pronged approach to address the crisis: managing demand, augmenting water supply, and improving water allocation. Five cross-cutting levers—strengthening institutions, reforming water tariffs and repurposing subsidies, adopting water accounting, leveraging data and technological innovations, and valuing water in trade—are essential for effective implementation and to attract private investment to finance the approach. Beyond water, addressing trade barriers, investing in education and skills development, and improving access to markets and financial services are critical for strengthening job and livelihood resilience amid a continental drying crisis.Publication Kyrgyz Republic Country Climate and Development Report(Washington, DC: World Bank, 2025-11-03)This Country Climate and Development Report (CCDR) on the Kyrgyz Republic aims to support the country’s development goals amid a changing climate. The CCDR considers two policy scenarios up to 2050: the business-as-usual (BAU) and high-growth scenarios. As it quantifies the likely impacts of climate change on the Kyrgyz economy between now and 2050, the report highlights key government actions to best prepare for and adapt to climate impacts (referred to as “with adaptation” measures), with a particular focus on the time horizon up to 2030. The CCDR also outlines a path to net zero emissions by 2050 (referred to as “with mitigation” measures, “decarbonization,” or, simply, “net zero 2050”), highlighting associated development co-benefits.Publication Taxes, Spending, and Equity: International Patterns and Lessons for Developing Countries(Washington, DC: World Bank, 2025-11-17)Taxes and public spending underpin the basic administration of government and finance the human capital and infrastructure investments needed for economic growth. They can also have a significant and immediate impact on poverty and inequality. The question of how public finance can support longer-term growth objectives while promoting equity has become even more important in recent years, given the high fiscal deficits and debt levels most countries emerged with in the aftermath of the COVID-19 pandemic. These included the increasing cost of debt and the need to restart environmentally sustainable growth while helping households address the learning losses and other social scars caused by the pandemic. This paper examines the global evidence on which households pay which taxes and who benefits from what spending, and critically, the net effect on different households across the income distribution. The aim is to identify the patterns and lessons that emerge for designing progressive fiscal policies. A global dataset of 96 countries is assembled, spanning all regions of the world and all national income levels, grounded in the Commitment to Equity (CEQ) approach to fiscal incidence.
