Abstract
To appreciate overall impacts of fragmentation, underlying channels, and potential heterogeneity by holding size, we distinguish average fragment size and mean inter-fragment distance as two aspects of this phenomenon. Estimating a cost function with associated input demand equations on a large nationally representative Indian survey, robust to endogeneity, suggests that fragmentation’s main impact is to reduce mean plot size below the threshold for mechanization. Higher inter-fragment distances increase costs for larger holdings, but by a much smaller magnitude. Implications as to when programs to consolidate holdings may make sense and ways to ensure their sustainability are discussed.

Publication Does Land Fragmentation Increase the Cost of Cultivation? Evidence from India(World Bank Group, Washington, DC, 2014-11)Although a large literature discusses the productivity effects of land fragmentation, measurement and potential endogeneity issues are often overlooked. This paper uses several measures of fragmentation and controls for endogeneity and crop choice by looking at inherited paddy and wheat plots to show that these issues matter empirically. While crop choice can mitigate effects, fragmentation as measured by the Simpson index increases production cost and fosters substitution of labor for machinery, especially for small and medium farmers. Greater distances between fragments have a smaller effect. Creating opportunities for market-based consolidation could be one step to limit fragmentation-induced cost increases.Publication Costs and Benefits of Land Fragmentation(World Bank, Washington, DC, 2015-06)This paper disentangles different aspects of land fragmentation and its impact on the efficiency of resource use. The paper uses information on the incidence of crop shocks to assess whether fragmentation provides benefits in reducing risk and parcel coordinates and terrain-adjusted travel times between parcels to more precisely account for the associated costs in 2010/11 data from Rwanda. While fragmentation increases the time required to move between a household’s parcels, this does not appear to affect overall technical efficiency on the farm. Fragmentation rather reduces the incidence of crop shocks and increases yields and productive efficiency. In Rwanda’s setting, interventions to reduce fragmentation may, therefore, be ineffective or counterproductive.Publication Inheritance Law Reform and Women’s Access to Capital : Evidence from India’s Hindu Succession Act(2010-06-01)This paper examines whether and to what extent amendments in inheritance legislation impact women's physical and human capital investments, using disaggregated household level data from India. The authors use inheritance patterns over three generations of individuals to assess the impact of changes in the Hindu Succession Act that grant daughters equal coparcenary birth rights in joint family property that were denied to daughters in the past. The causal effect is isolated by exploiting the variation in the timing of father's death to compare within household bequests of land given to sons and daughters in the states of Maharashtra and Karnataka. The analysis shows that the amendment significantly increased daughters' likelihood to inherit land, but that even after the amendment substantial bias persists. The results also indicate a robust increase in educational attainment of daughters, suggesting an alternative channel of wealth transfer.Publication Short-Term Effects of India's Employment Guarantee Program on Labor Markets and Agricultural Productivity(World Bank, Washington, DC, 2016-05)This paper uses a large national household panel from 1999/2000 and 2007/08 to analyze the short-term effects of India's Mahatma Gandhi National Rural Employment Guarantee Scheme on wages, labor supply, agricultural labor use, and productivity. The scheme prompted a 10-point wage increase and higher labor supply to nonagricultural casual work and agricultural self-employment. Program-induced drops in hired labor demand were more than outweighed by more intensive use of family labor, machinery, fertilizer, and diversification to crops with higher risk-return profiles, especially by small farmers. Although the aggregate productivity effects were modest, total employment generated by the program (but not employment in irrigation-related activities) significantly increased productivity, suggesting alleviation of liquidity constraints and implicit insurance provision rather than quality of works undertaken as a main channel for program-induced productivity effects.Publication Costs and Benefits of Land Fragmentation(Published by Oxford University Press on behalf of the World Bank, 2019-10)Panel data from Rwanda allow us to explore costs and benefits from land fragmentation in a non-mechanized setting using two methodological improvements, namely (i) a terrain-adjusted measure of travel time/cost required to visit all parcels to measure fragmentation; and (ii) instrumental variable (IV) approaches that use measures for inherited/allocated parcels and past displacement as instruments. Results suggest that fragmentation as measured by travel cost negatively affect yield, intensity of labor use, and technical efficiency while reducing yield variability. With some 7 percent increase in yields, the size of the estimated impact of potential consolidation remains modest, suggesting that in an unmechanized setting such as the one studied here, the costs of programs to reduce fragmentation may outweigh the benefits.

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 World Development Report 1984(New York: Oxford University Press, 1984)Long-term needs and sustained effort are underlying themes in this year's report. As with most of its predecessors, it is divided into two parts. The first looks at economic performance, past and prospective. The second part is this year devoted to population - the causes and consequences of rapid population growth, its link to development, why it has slowed down in some developing countries. The two parts mirror each other: economic policy and performance in the next decade will matter for population growth in the developing countries for several decades beyond. Population policy and change in the rest of this century will set the terms for the whole of development strategy in the next. In both cases, policy changes will not yield immediate benefits, but delay will reduce the room for maneuver that policy makers will have in years to come.Publication The Container Port Performance Index 2023(Washington, DC: World Bank, 2024-07-18)The Container Port Performance Index (CPPI) measures the time container ships spend in port, making it an important point of reference for stakeholders in the global economy. These stakeholders include port authorities and operators, national governments, supranational organizations, development agencies, and other public and private players in trade and logistics. The index highlights where vessel time in container ports could be improved. Streamlining these processes would benefit all parties involved, including shipping lines, national governments, and consumers. This fourth edition of the CPPI relies on data from 405 container ports with at least 24 container ship port calls in the calendar year 2023. As in earlier editions of the CPPI, the ranking employs two different methodological approaches: an administrative (technical) approach and a statistical approach (using matrix factorization). Combining these two approaches ensures that the overall ranking of container ports reflects actual port performance as closely as possible while also being statistically robust. The CPPI methodology assesses the sequential steps of a container ship port call. ‘Total port hours’ refers to the total time elapsed from the moment a ship arrives at the port until the vessel leaves the berth after completing its cargo operations. The CPPI uses time as an indicator because time is very important to shipping lines, ports, and the entire logistics chain. However, time, as captured by the CPPI, is not the only way to measure port efficiency, so it does not tell the entire story of a port’s performance. Factors that can influence the time vessels spend in ports can be location-specific and under the port’s control (endogenous) or external and beyond the control of the port (exogenous). The CPPI measures time spent in container ports, strictly based on quantitative data only, which do not reveal the underlying factors or root causes of extended port times. A detailed port-specific diagnostic would be required to assess the contribution of underlying factors to the time a vessel spends in port. A very low ranking or a significant change in ranking may warrant special attention, for which the World Bank generally recommends a detailed diagnostic.Publication Global Economic Prospects, January 2025(Washington, DC: World Bank, 2025-01-16)Global growth is expected to hold steady at 2.7 percent in 2025-26. However, the global economy appears to be settling at a low growth rate that will be insufficient to foster sustained economic development—with the possibility of further headwinds from heightened policy uncertainty and adverse trade policy shifts, geopolitical tensions, persistent inflation, and climate-related natural disasters. Against this backdrop, emerging market and developing economies are set to enter the second quarter of the twenty-first century with per capita incomes on a trajectory that implies substantially slower catch-up toward advanced-economy living standards than they previously experienced. Without course corrections, most low-income countries are unlikely to graduate to middle-income status by the middle of the century. Policy action at both global and national levels is needed to foster a more favorable external environment, enhance macroeconomic stability, reduce structural constraints, address the effects of climate change, and thus accelerate long-term growth and development.Publication Digital Progress and Trends Report 2023(Washington, DC: World Bank, 2024-03-05)Digitalization is the transformational opportunity of our time. The digital sector has become a powerhouse of innovation, economic growth, and job creation. Value added in the IT services sector grew at 8 percent annually during 2000–22, nearly twice as fast as the global economy. Employment growth in IT services reached 7 percent annually, six times higher than total employment growth. The diffusion and adoption of digital technologies are just as critical as their invention. Digital uptake has accelerated since the COVID-19 pandemic, with 1.5 billion new internet users added from 2018 to 2022. The share of firms investing in digital solutions around the world has more than doubled from 2020 to 2022. Low-income countries, vulnerable populations, and small firms, however, have been falling behind, while transformative digital innovations such as artificial intelligence (AI) have been accelerating in higher-income countries. Although more than 90 percent of the population in high-income countries was online in 2022, only one in four people in low-income countries used the internet, and the speed of their connection was typically only a small fraction of that in wealthier countries. As businesses in technologically advanced countries integrate generative AI into their products and services, less than half of the businesses in many low- and middle-income countries have an internet connection. The growing digital divide is exacerbating the poverty and productivity gaps between richer and poorer economies. The Digital Progress and Trends Report series will track global digitalization progress and highlight policy trends, debates, and implications for low- and middle-income countries. The series adds to the global efforts to study the progress and trends of digitalization in two main ways: · By compiling, curating, and analyzing data from diverse sources to present a comprehensive picture of digitalization in low- and middle-income countries, including in-depth analyses on understudied topics. · By developing insights on policy opportunities, challenges, and debates and reflecting the perspectives of various stakeholders and the World Bank’s operational experiences. This report, the first in the series, aims to inform evidence-based policy making and motivate action among internal and external audiences and stakeholders. The report will bring global attention to high-performing countries that have valuable experience to share as well as to areas where efforts will need to be redoubled.
