Abstract
In response to rising inequality following decades of trade liberalization, many countries are adopting trade restrictions. Can temporary trade restrictions have long-lasting effects on the spatial distribution of employment and resource allocation? To analyze this, this paper exploits the civil war in Côte d'Ivoire (2002-07), which disrupted access to the world market for two neighboring landlocked countries: Mali and Burkina Faso. The Ivorian war forced rerouting of trade from the Abidjan route to non-Abidjan routes. This paper builds a general equilibrium model where a subsistence-based autarkic hinterland coexists with an integrated segment, and there are two alternative routes to international markets. A trade shock to one route affects resource allocation in both routes by shifting the spatial margins of market integration and sectoral specialization. The effects are heterogeneous, depending on the pre-war market access of a location. The empirical analysis takes advantage of panel data and estimates the effects on structural change in employment on the non-Abidjan route using a triple difference design with location fixed effects. The areas that remain in autarkic equilibrium before and after the trade shock provide plausible estimates of the changes arising from long-term factors unrelated to the trade shock. The estimates show that the temporary trade shock created divergence between the Abidjan and non-Abidjan routes, with accelerated structural change in favor of manufacturing and services employment in the non-Abidjan route. This paper finds evidence of persistence in the effects through higher sunk investment in built-up density, agglomeration through concentration of skilled labor and greater public investment in complementary inputs such as electricity infrastructure (measured by nightlights density).

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 General Equilibrium Effects of Land Market Restrictions on Labor Market : Evidence from Wages in Sri Lanka(2010-10-01)Taking advantage of a historical quasi-experiment in Sri Lanka, this paper provides evidence on the effects of land market restrictions on wages and its spatial pattern. The empirical specification is derived from a general equilibrium model that predicts that the adverse effects of land market restrictions on wages will be less in remote locations. For identification, the study exploits the effects of historical malaria prevalence on the incidence of land restrictions through its effects on "crown land". During the 16th to early 20th centuries, areas severely affected by malaria were abandoned by households and the land was taken over by the government. These lands that were later distributed through resettlement programs are subject to sales, rental, and mortgage restrictions. The variations in the amount of crown land resulting from different intensity of historical malaria provide a source of exogenous variations in the incidence of land restrictions in a sub-district. The results show that land restrictions reduce wages substantially, and this effect is smaller in remote locations. A 1 percent increase in land restrictions reduces wages by about 6.6 percent at the median travel time from an urban center, and the effect becomes effectively zero after 6 hours of travel time.Publication Transport Costs, Comparative Advantage, and Agricultural Development(World Bank, Washington, DC, 2018-07)This paper studies the effects of a large reduction in transport costs on agricultural development in a developing country, with a focus on the interactions among the comparative advantage and transport costs of a location, and the transport intensity and value of a commodity. The paper extends the von Thunen model of land allocation to incorporate costly technology adoption and comparative advantage based on land productivity. The theoretical analysis predicts spatial non-linearity in cropland allocation. A reduction in transport costs leads to adoption of productivity-enhancing inputs in the newly-connected region, and an increase in the share of land devoted to the high-value transport-intensive crop. The strongest effect is felt in areas that are not too near or too far from the center and have a higher land productivity in transport intensive crop. The empirical context of the analysis is the Jamuna bridge in Bangladesh, which opened in 1998 and reduced the transport costs from the poor hinterland in the northwest to the capital city (Dhaka) by more than 50 percent. Using sub-district level panel data, the paper implements doubly robust estimators in a difference-in-difference design. The analysis finds that the construction of Jamuna bridge led to increased adoption of technology (fertilizer, irrigation, greenness, and cropping intensity) and reallocation of land from low-value and nonperishable rice to high-value crops, pulses, and vegetables. The evidence indicates spatial nonlinearity in the effects on cropping intensity and the reallocation of land in areas with comparative advantage in vegetable production. For cropping intensity, the magnitude of the effect is large in the intermediate distance (130-150 kilometers) from the bridge. In areas with relatively higher vegetable productivity, land allocated to rice declined, and land was reallocated from high-yielding variety rice to vegetables in the intermediate distance (110-150 kilometers). This improved productive efficiency by aligning the cropping pattern more closely with comparative advantage. The bridge thus led to agricultural development through technology adoption, higher cropping intensity, and reducing the spatial mismatch between land suitability and crop choice.Publication Agricultural Productivity and Non-Farm Employment(World Bank, Washington, DC, 2016-05)This paper provides evidence on the impacts of agricultural productivity on employment growth and structural transformation of non-farm activities. To guide the empirical work, this paper develops a general equilibrium model that emphasizes distinctions among non-farm activities in terms of tradable-non-tradable and the formal-informal characteristics. The model shows that when a significant portion of village income is spent on town/urban goods, restricting empirical analysis to the village sample leads to underestimation of agriculture's role in employment growth and transformation of non-farm activities. Using rainfall as an instrument for agricultural productivity, empirical analysis finds a significant positive effect of agricultural productivity growth on growth of informal (small-scale) manufacturing and skilled services employment, mainly in education and health services. For formal employment, the effect of agricultural productivity growth on employment is found to be largest in the samples that include urban areas and rural towns compared with rural areas alone. Agricultural productivity growth is found to induce structural transformation within the services sector with employment in formal/skilled services growing at a faster pace than that of low skilled services.Publication Land Market Restrictions, Women's Labor Force Participation, and Wages in a Rural Economy(World Bank, Washington, DC, 2015-12)This paper analyzes the effects of land market restrictions on the rural labor market outcomes for women. The existing literature emphasizes two mechanisms through which land restrictions can affect the economic outcomes: the collateral value of land, and (in) security of property rights. Analysis of this paper focuses on an alternative mechanism where land restrictions increase costs of migration out of villages. The testable prediction of collateral effect is that both wages and labor force participation move in the same direction, and insecurity of property rights reduces labor force participation and increases wages. In contrast, if land restrictions work primarily through higher migration costs, labor force participation increases, while wages decline. For identification, this paper exploits a natural experiment in Sri Lanka where historical malaria played a unique role in land policy. This paper provides robust evidence of a positive effect of land restrictions on womens labor force participation, but a negative effect on female wages. The empirical results thus contradict a collateral or insecure property rights effect, but support migration costs as the primary mechanism.Publication Bridge to Bigpush or Backwash?(World Bank, Washington, DC, 2018-07)This paper uses a quasi-experimental study of a major bridge construction in Bangladesh to understand the effects of a large reduction in trade costs on the pattern of structural change and agricultural productivity. The paper develops a spatial general equilibrium model with a core and two hinterlands at the opposite sides separated by rivers, and allows for productivity gains through agglomeration in the agriculture and manufacturing sectors. The model yields insights different from the standard core-periphery and trade models: (i) the newly connected hinterland may experience higher population density and agricultural productivity despite significant de-industrialization; (ii) even with increased specialization in agriculture, the share of agricultural employment may decline when interregional trade requires local services (such as processing and trading); and (iii) the strongest effects on employment structure are felt not necessarily in the areas next to the bridge but in the areas that move out of autarky as a result of the bridge. The empirical estimation uses doubly robust estimators in a difference-in-difference design where the comparison hinterland comes from a region which was supposed to be connected to the core (capital city) by the proposed, but not yet constructed, Padma bridge. In the short run, there is significant labor reallocation from agriculture to services in the connected hinterland, but no perceptible effects on the employment share of manufacturing, population density, and night-lights. In the long run, the labor share of manufacturing declines in the treatment hinterland and increases in the core. However, there are significant positive effects on population density, night light luminosity, and agricultural yields in the treatment hinterland which contradict backwash effects of the bridge. The effects of the bridge on intersectoral labor allocation are spatially heterogeneous, with relatively weak effects in the areas close to the bridge.

Publication Road Capacity, Domestic Trade and Regional Outcomes(World Bank, Washington, DC, 2021-09)What is the impact on intranational trade and regional economic outcomes when the quality and lane capacity of an existing paved road network is expanded significantly? This paper investigates this question for the case of Turkey, which undertook a large-scale public investment in roads during the 2000s. Using spatially disaggregated data on road upgrades and domestic transactions, the paper estimates a large positive impact of reduced travel times on trade as well as local manufacturing employment and wages. A quantitative exercise using a workhorse model of spatial equilibrium implies heterogeneous effects across locations, with aggregate real income gains reaching 2–3 percent in the long run. Reductions in travel times increased the local employment-to-population ratio but had no effect on local population. The model is extended by endogenizing the labor supply decision to capture this finding. The model-implied elasticity of employment rates to travel time reductions captures about one-third of the empirical elasticity.Publication China’s Export Growth and the China Safeguard : Threats to the World Trading System?(2010-05-01)Is there evidence from China's pre-WTO accession period that newly imposed U.S. or EU import restrictions deflect Chinese exports to third markets? The authors examine this question by drawing on a newly constructed data set of U.S. and EU product-level import restrictions on Chinese trade imposed between 1992 and 2001 and estimate their impact on Chinese exports to 38 alternative markets. There is no systematic evidence that the import restrictions imposed during this period resulted in Chinese exports surging to such alternate destinations. To the contrary, there is weak evidence of a chilling effect on China's exports to third markets.Publication Monetary Policy Strategies for Latin America(World Bank, Washington, DC, 2001-10)The authors examine possible monetary policy strategies for Latin America that may help lock in the gains the region attained in the fight against inflation in the 1990s. Instead of focusing the debate about the conduct of monetary policy on whether the nominal exchange rate should be fixed or flexible, the focus should be on whether the monetary policy regime appropriately constrains discretion in monetary policymaking. Three basic frameworks deserve serious discussion as possible long-run strategies for monetary policy in Latin America. The authors examine the advantages and disadvantages of a hard exchange-rate peg, monetary targeting, and inflation targeting, in light of monetary policy's recent track record in several Latin American countries, looking for clues about which of the strategies might be best suited to economies in the region. The answer: It depends on the country's institutional environment. Some countries appear not to have the institutions to constrain monetary policy if discretion is allowed. In those countries, there is a strong argument for hard pegs, including full dollarization, that allow little or no discretion to monetary authorities. In countries such as Chile, which can constrain discretion, inflation targeting is likely to produce a monetary policy that keeps inflation low yet appropriately copes with domestic and foreign shocks. Monetary targeting as a strategy for Latin America is not viable because of the likely instability of the relationship between inflation and monetary aggregates, of which there is ample international evidence. No monetary strategy can solve the basic problems that have existed in Latin American economies for a long time. The authors welcome the recent move in Latin American countries toward inflation targeting, but say no policy will succeed unless government policies also create the right institutional environment.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 On the Effects of Enforcement on Illegal Markets(Published by Oxford University Press on behalf of the World Bank, 2017-06-01)This paper studies the effects of enforcement on illegal behavior in the context of a large aerial spraying program designed to curb coca cultivation in Colombia. In 2006, the Colombian government pledged not to spray a 10 km band around the frontier with Ecuador due to diplomatic frictions arising from the possibly negative collateral effects of this policy on the Ecuadorian side of the border. We exploit this variation to estimate the effect of spraying on coca cultivation by regression discontinuity around the 10 km threshold and by conditional differences in differences. Our results suggest that spraying one additional hectare reduces coca cultivation by 0.022 to 0.03 hectares; these effects are too small to make aerial spraying a cost-effective policy for reducing cocaine production in Colombia.
