Migrants, Markets, and Mayors: Rising above the Employment Challenge in Africa’s Secondary Cities
(Washington, DC: World Bank, 2023-12-14) Christiaensen, Luc; Lozano-Gracia, Nancy; eds.
Research on migration and urban development in Africa has primarily focused on larger cities and rural-to-urban migration. However, 97 percent of Africa’s urban centers have fewer than 300,000 inhabitants, and a sizable share of urban migrants come from other urban areas. A more holistic and dynamic perspective, incorporating migration flows along the full urban hierarchy, as well as urban-urban migrants, is needed to better understand and leverage migration for urban development. Migrants, Markets, and Mayors: Rising above the Employment Challenge in Africa’s Secondary Cities draws on demographic data, research literature, key informant interviews, and empirical research to better understand how migrants in Africa’s secondary cities fare in urban labor markets, how they affect aggregate urban productivity, and how mayors can leverage migrants’ potential to the benefit of all. It explores these questions across countries and four urban case settings: Jijiga in Ethiopia, Jinja in Uganda, and Jendouba and Kairouan in Tunisia. Although mayors in secondary cities often see migrants as a burden to their cities’ labor markets and a threat to development, the report finds that migrants contribute increasingly less to urban population growth and that they usually strengthen the resident labor force. The report also finds that labor market outcomes for migrants are at least as good as those for nonmigrants. Africa’s secondary cities are well placed to leverage migration, but evidence-based policies are needed to manage the growth and development of land and labor markets. The report reviews policy options that mayors can take to strengthen the financial, technical, and planning capacity of secondary cities and better leverage migration to benefit migrants and nonmigrants alike.
Jobs, Food and Greening: Exploring Implications of the Green Transition for Jobs in the Agri-food System
(World Bank, Washington, DC, 2023-05-16) Nico, Gianluigi; Christiaensen, Luc
The agri-food system (AFS) employs about one third of the global workforce and contributes about one third of global greenhouse gas (GHG) emissions. This together with its large exposure to the effects of climate change and environmental degradation makes what happens in AFS central to the green transition and its implications for jobs and the structural transformation. Microeconomic evidence suggests that the adoption of climate smart agricultural practices will increase labor requirements, at least in the short run and at lower levels of incomes, when its mechanization is still limited. Econometric macro-model-based simulations suggest however that especially substantial investment in climate friendly agricultural R&D as well as soil and water preserving practices and market integration will more than offset the negative effects of climate change and even accelerate the structural transformation, especially in Sub Saharan Africa. Overall, the findings underscore the tremendous potential of increasing agricultural and climate friendly R&D investment for brokering an environmentally sustainable structural transformation. Repurposing of agriculture’s current US$ 638 billion support package towards supporting more climate friendly practices, including to overcome the time lag between the moment of investment and the realization of the benefits, provides an important policy entry point.
Towards a Just Coal Transition Labor Market Challenges and People’s Perspectives from Wielkopolska
(Washington, DC: World Bank, 2022-10-18) Christiaensen, Luc; Honorati, Maddalena; Wrona, Sylwia Michalina
Part of a three-region set of papers analyzing coal-related labor market challenges in Poland, this paper focuses on Wielkopolska, which is most advanced in the transition out of coal. Finding viable job transitions is of enormous importance. The findings call for a more territorial-oriented approach to brokering the coal transition, rather than a sectoral one. First, even though limited from a regional perspective (4,000 workers), affected jobs are highly concentrated in a few already lagging and depopulating municipalities. Second, while coal-related workers are similarly skilled as other workers in Wielkopolska, non-coal related workers in the at-risk municipalities are substantially less skilled, exposing them to potential displacement effects. Finally, while ready to work and to be re-skilled, discrete choice experiments about their job attribute preferences show that all workers are averse both to commuting and relocating for work, even more so than in Silesia and Lower Silesia. Complementary social protection and employment support will be needed, and the paper suggests some policy options based on international experience. The paper concludes by illustrating how a big-data driven job-matching tool, calibrated on the Polish labor market, could be used to assist caseworkers in identifying “viable-job-transition-pathways” for affected workers as well as to help policymakers identify reskilling needs and attract investments.
Rural Employment in Africa: Trends and Challenges
(Washington, DC: World Bank, 2022-02-23) Christiaensen, Luc
Africa’s rural population continues to expand rapidly and labor productivity in agriculture and many rural off farm activities remains low. This paper uses the lens of a dual economy and the associated patterns of agricultural, rural, and structural transformation to review the evolution of Africa’s rural employment and its inclusiveness. Many African countries still find themselves in an early stage of the agricultural and rural transformation. Given smaller sectoral productivity gaps than commonly assumed, greater size effects and larger spillovers, investment in agriculture and the rural off-farm economy remains warranted to broker the transition to more and more productive rural employment. The key policy questions thus become how best to invest in the agri-food system (on and increasingly also off the farm) and how best to generate demand for nonagricultural goods and services which rural households can competitively produce. Informing these choices continues to present a major research agenda, with digitization, the imperative of greening and intra-African liberalization raising many unarticulated and undocumented opportunities and challenges.
Towards a Just Coal Transition: Labor Market Challenges and People’s Perspectives from Lower Silesia
(World Bank, Washington, DC, 2022) Christiaensen, Luc; Gajderowicz, Tomasz; Wrona, Sylwia
Part of a three-region set of papers analyzing coal-related labor market challenges in Poland, this paper focuses on Lower Silesia. The findings call for a more territorial-oriented approach to brokering the coal transition, rather than a sectoral one. First, while the number of people directly and indirectly affected by coal mine closures in Lower Silesia (~5,500) is relatively small compared to the total regional labor force (<1%), affected workers are heavily concentrated geographically. Second, workers in heavily affected municipalities have lower foundational (but better technical) skills than their regional and national counterparts, and already operate in lagging local economies. Third, while eager to work, discrete choice experiments about their job attribute preferences show that they are averse to both, commuting and relocating for work, even though less so than in Silesia and Wielkopolska, the two other regions. Together this suggests that there are important welfare and political economic benefits to adequate job creation locally. The paper further advances a data-driven viable-job-matching tool specifically tailored to the Polish labor market and illustrates how it could be used to assess the potential of local labor markets and future investments to absorb the coal-affected workers accounting for their skills profile, re/upskilling needs and job attribute preferences.
Towards a Just Coal Transition Labor Market Challenges and People’s Perspectives from Silesia
(World Bank, Washington, DC, 2022) Ferré, Céline; Christiaensen, Luc; Gajderowicz, Tomasz; Ruppert Bulmer, Elizabeth; Wrona, Sylwia
Part of a three-region set of papers analyzing coal-related labor market challenges in Poland, this paper focuses on Silesia. The findings call for a more territorial-oriented approach to brokering the coal transition, rather than a sectoral one. First, the number of jobs directly linked to coal-mining in Silesia is substantial, with 72,000 employees in the mining conglomerates, and an additional 17,000 providing goods and services to the mines. Second, coal-related employment is heavily concentrated geographically: as much as 40 percent of the population of Bieruńsko-Iedziński is employed directly and indirectly in the mining sector, and 80 percent of the mining conglomerates' contract value goes to subcontractors within a 20km radius of the mines. Third, the coal sector is highly integrated among a few large firms: 28 percent of the indirect workforce is employed by 10 subcontractors. Fourth, workers in the mining conglomerates have lower foundational (but better technical) skills than their regional and national counterparts, especially those with lower education. Finally, while eager to work, discrete choice experiments about their job attribute preferences show that they are averse to both, commuting and relocating for work, even though less so than in Wielkopolska, yet more so that in Lower Silesia, the two other regions. Together this suggests that there are important welfare and political economic benefits to adequate job creation locally. The paper further advances a data-driven viable-job-matching tool specifically tailored to the Polish labor market and illustrates how it could be used to assess the potential of local labor markets and future investments to absorb the coal-affected workers accounting for their skills profile, re/upskilling needs, and job attribute preferences.
Migrants, Markets, and Mayors: Rising Above the Employment Challenge in Africa’s Secondary Cities – Key Insights
(World Bank, Washington, DC, 2021-12) Christiaensen, Luc
In our rapidly urbanizing world, mayors often see migrants as a burden to their city’s labor market and a threat to its development. Drawing on national household surveys and four secondary city case studies in Africa, this study finds that migrants, being younger, better educated and/or complementary to the resident labor force, usually strengthen the urban labor force. In secondary cities, labor market outcomes for migrants are at least as good as those for residents. Migrants also contribute increasingly less to urban population growth. Secondary cities thus appear well placed to leverage migration. This requires good urban management that develops land and labor markets, prepares for growth and benefits everyone, migrants as well as residents. Migrant specific interventions are warranted when divisions between natives and migrants are deep. Strengthening the financial, technical, and planning capacity of towns to better integrate migrants is part and parcel of the good job’s agenda.
Assessing the Affordability of Nutrient-Adequate Diets
(World Bank, Washington, DC, 2021-11) Schneider, Kate; Christiaensen, Luc; Webb, Patrick; Masters, William A.
The affordability of nutritious diets is increasingly used as a metric of how well a food system provides access to nutritious diets for all. Recent work on least-cost diets has focused on individuals, while most food and anti-poverty programs and policies target the household level. Members within households have differing nutritional needs, presenting the methodological question: how should the cost of nutritious diets be estimated at the household level This study develops bounds on the cost, affordability, and seasonal variation of least-cost diets for whole households, illustrated with the example of Malawi. When intrahousehold sharing is not possible to observe, the bounded approach provides insights into the range of the cost and affordability, and the extent to which the cost may vary seasonally. The results reveal that when meals are shared, ignoring demographic diversity within households greatly underestimates the affordability of adequate diets.
Consumption Subaggregates Should Not Be Used to Measure Poverty
(Published by Oxford University Press on behalf of the World Bank, 2021-09-06) Ligon, Ethan; Christiaensen, Luc; Sohnesen, Thomas Pave
Frequent measurement of poverty is challenging because measurement often relies on complex and expensive expenditure surveys that try to measure expenditures on a comprehensive consumption aggregate. This paper investigates the use of consumption subaggregates instead. The use of consumption subaggregates is theoretically justified if and only if all Engel curves are linear for any realization of prices. This is very stringent. However, it may be possible to empirically identify certain goods that happen to have linear Engel curves given prevailing prices, and when the effect of price changes is small, such a subaggregate might work in practice. The paper constructs such linear subaggregates using data from Rwanda, Tanzania, and Uganda. The findings show that using subaggregates is ill advised in practice as well as in theory. This also raises questions about the consistency of the poverty tracking efforts currently applied across countries, since obtaining exhaustive consumption measures remains an unmet challenge.
Economic and Social Development along the Urban-Rural Continuum: New Opportunities to Inform Policy
(World Bank, Washington, DC, 2021-08) Cattaneo, Andrea; Adukia, Anjali; Brown, David L.; Christiaensen, Luc; Evans, David K.; Haakenstad, Annie; McMenomy, Theresa; Partridge, Mark; Vaz, Sara; Weiss, Daniel J.
The economic and social development of nations relies on their population having physical access to services and employment opportunities. For the vast majority of the 3.4 billion people living in rural locations, this largely depends on their access to urban centers of different sizes. Similarly, urban centers depend on their rural hinterlands. Building on the literature on functional areas/territories and the rural-urban continuum as well as insights from central place theory, this review paper advances the notion of catchment areas differentiated along an urban-to-rural continuum to capture these urban-rural interconnections. It further shows how a new, publicly available data set operationalizing this concept can shed new light on policy making across a series of development fields, including institutions and governance, urbanization and food systems, welfare and poverty, and access to health and education services. Together the insights support a more geographically nuanced perspective on development.
