Abstract
This paper studies the effect of a local sectoral productivity shock on subnational structural transformation. The analysis is based on regional input-output tables constructed for 2004 and 2013 and available censuses of firms in 2003 and 2013 for Ghana. Based on the data, the analysis confirms the occurrence of a mining productivity shock. Between 2004 and 2013, mining grew dramatically as a share of gross domestic product. The mining shock occurred primarily in the south of Ghana with much larger increases in mining’s share in regional output, the number of mining firms, and mining employment than in the north of the country. The findings show that the mining productivity shock led to growing regional (north-south) differences in intersectoral linkages, with greater intermediate use of mining output and a larger sectoral total factor productivity ratio between mining and manufacturing in the south than in the north. Informed by international evidence of strong intersectoral linkages between mining and heavy manufacturing industries, the paper examines the performance of heavy manufacturing in response to the mining productivity shock. The elasticity of heavy manufacturing to mining employment growth is 50 percent larger in the south than in the north, generated by an increase in both average firm employment and the entry of new firms. These north-south differences are interpreted as possibly due to weak interregional production linkages.

Publication Barriers to Growth-Enhancing Structural Transformation(World Bank, Washington, DC, 2021-06)The movement of workers from the farm sector to a more productive nonfarm sector has failed to generate significant gains in labor productivity in recent decades in many developing countries. This paper offers a new perspective on the barriers to growth-enhancing structural transformation, combining structural modeling with enterprise census data from Ghana. The paper argues that subnational differences in the intersectoral productivity gap between the nonfarm informal and formal sectors constrain the productivity gain from structural transformation. In Ghana, intersectoral productivity gaps among the richer regions are on average three times larger than among the poorer regions. The disparity in regional intersectoral productivity gaps is modeled as reflecting the disparity in the regional misallocation of labor between the informal and formal sectors. Misallocation is identified as the output wedge between the informal and formal sectors. Simulations suggest that a more productive nonfarm informal sector reduces the disparity in regional intersectoral productivity gaps and, in turn, increases national productivity and the contribution of structural transformation to national productivity. For example, a 90-percent reduction in the disparity in regional intersectoral productivity gaps raises Ghana’s national aggregate productivity by 11.9 percent and the contribution of structural transformation to productivity by 19.7 percent.Publication Structural Transformation and Labor Market Performance in Ghana(World Bank, Washington, DC, 2020-11-24)Structural transformation can spur economic growth and development if it increases overall productivity growth. A labor market environment that enables workers and enterprises to transition smoothly across sectors and into more productive economic pursuits can enhance the effect of structural transformation on economic growth. This study examines Ghana’s recent record of structural transformation and labor market performance. Based on the findings, the study proposes ways to further transform the country’s economy, in a way that stimulates stronger, sustained growth and produces gainful, productive, and inclusive private employment. The COVID-19 (coronavirus) pandemic and associated global economic crisis have posed a substantial setback to Ghana’s economic progress and plans, but these challenges also underscore the need for structural transformation that can both strengthen economic performance and improve labor conditions and outcomes.Publication Structural Challenges for SOEs in Belarus : A Case Study of the Machine Building Sector(World Bank, Washington, DC, 2012-03)Are Belarus's state owned enterprises positioned to grow in 2011-2015 as successfully as in 1995-2006? State owned enterprises account for 55 percent of Belarus's output and two-thirds of overall employment; economic growth in 1995-2006 was the result of capacity expansion and productivity improvements in state owned enterprises. These sources of economic growth originated in policy decisions that preserved the functioning of the command and control economy and allowed the country to exploit preferential commercial access to the Russian market in several goods and services. Are the same reasons likely to facilitate the performance of state owned enterprises and overall economic growth in 2011-2015? This paper concludes that this is not likely to happen. Times have changed: the slowdown in production and exports in 2009-2010 was unquestionably associated with a transitory decline in demand for durable goods in Russia. But there have also been more permanent market forces at work: a steady increase in competition in Russia and other Commonwealth of Independent States markets resulting from low-price Chinese and Russian-produced capital goods; and a shift in demand from low-quality/low price to high-quality, high-price transport equipment demand in Russia and other Commonwealth of Independent States markets. And these forces are there to stay. This conclusion leads to the following questions: Would state owned enterprises be able to adapt to observed market changes? What reforms would be relevant to facilitate the necessary adaptation?Publication Structural Transformation, Productivity, and Employment in Ghana 1991-2012(World Bank, Washington, DC, 2015-10)Ghana’s recent economic growth was accompanied by significant structural transformation. Over the past two decades Ghana has enjoyed sustained economic growth combined with some degree of transformation away from agriculture. This shift was associated with a considerable increase in the relative share of services. In recent years, the industry share of GDP has also picked up although the growth of employment in that sector has been comparatively slow.Publication Structural Transformation and Productivity Growth in Africa(World Bank, Washington, DC, 2015-12)Uganda’s economy underwent significant structural change in the 2000s whereby the share of non-tradable services in aggregate employment rose by about 7 percentage points at the expense of the production of tradable goods. The process also involved a 12-percentage-point shift in employment away from small and medium enterprises and larger firms in manufacturing and commercial agriculture mainly to microenterprises in retail trade. In addition, the sectoral reallocation of labor on these two dimensions coincided with significant growth in aggregate labor productivity. However, in and of itself, the same reallocation could only have held back, rather than aid, the observed productivity gains. This was because labor was more productive throughout the period in the tradable goods sector than in the non-tradable sector. Moreover, the effect on aggregate labor productivity of the reallocation of employment between the two sectors could only have been reinforced by the impacts on the same of the rise in the employment share of microenterprises. The effect was also strengthened by a parallel employment shift across the age distribution of enterprises that raised sharply the employment share of established firms at the expense of younger ones and startups. Not only was labor consistently less productive in microenterprises than in small and medium enterprises and larger enterprises across all industries throughout the period, it was also typically less productive in more established firms than in younger ones.

Publication Doing Business 2014 : Understanding Regulations for Small and Medium-Size Enterprises(Washington, DC: World Bank Group, 2013-10-28)Eleventh in a series of annual reports comparing business regulation in 185 economies, Doing Business 2014 measures regulations affecting 11 areas of everyday business activity: Starting a business, Dealing with construction permits, Getting electricity, Registering property, Getting credit, Protecting investors, Paying taxes, Trading across borders, Enforcing contracts, Closing a business, Employing workers. The report updates all indicators as of June 1, 2013, ranks economies on their overall “ease of doing business”, and analyzes reforms to business regulation – identifying which economies are strengthening their business environment the most. The Doing Business reports illustrate how reforms in business regulations are being used to analyze economic outcomes for domestic entrepreneurs and for the wider economy. Doing Business is a flagship product by the World Bank and IFC that garners worldwide attention on regulatory barriers to entrepreneurship. More than 60 economies use the Doing Business indicators to shape reform agendas and monitor improvements on the ground. In addition, the Doing Business data has generated over 870 articles in peer-reviewed academic journals since its inception.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 Classroom Assessment to Support Foundational Literacy(Washington, DC: World Bank, 2025-03-21)This document focuses primarily on how classroom assessment activities can measure students’ literacy skills as they progress along a learning trajectory towards reading fluently and with comprehension by the end of primary school grades. The document addresses considerations regarding the design and implementation of early grade reading classroom assessment, provides examples of assessment activities from a variety of countries and contexts, and discusses the importance of incorporating classroom assessment practices into teacher training and professional development opportunities for teachers. The structure of the document is as follows. The first section presents definitions and addresses basic questions on classroom assessment. Section 2 covers the intersection between assessment and early grade reading by discussing how learning assessment can measure early grade reading skills following the reading learning trajectory. Section 3 compares some of the most common early grade literacy assessment tools with respect to the early grade reading skills and developmental phases. Section 4 of the document addresses teacher training considerations in developing, scoring, and using early grade reading assessment. Additional issues in assessing reading skills in the classroom and using assessment results to improve teaching and learning are reviewed in section 5. Throughout the document, country cases are presented to demonstrate how assessment activities can be implemented in the classroom in different contexts.Publication World Development Report 2011(World Bank, 2011)The 2011 World development report looks across disciplines and experiences drawn from around the world to offer some ideas and practical recommendations on how to move beyond conflict and fragility and secure development. The key messages are important for all countries-low, middle, and high income-as well as for regional and global institutions: first, institutional legitimacy is the key to stability. When state institutions do not adequately protect citizens, guard against corruption, or provide access to justice; when markets do not provide job opportunities; or when communities have lost social cohesion-the likelihood of violent conflict increases. Second, investing in citizen security, justice, and jobs is essential to reducing violence. But there are major structural gaps in our collective capabilities to support these areas. Third, confronting this challenge effectively means that institutions need to change. International agencies and partners from other countries must adapt procedures so they can respond with agility and speed, a longer-term perspective, and greater staying power. Fourth, need to adopt a layered approach. Some problems can be addressed at the country level, but others need to be addressed at a regional level, such as developing markets that integrate insecure areas and pooling resources for building capacity Fifth, in adopting these approaches, need to be aware that the global landscape is changing. Regional institutions and middle income countries are playing a larger role. This means should pay more attention to south-south and south-north exchanges, and to the recent transition experiences of middle income countries.Publication World Development Report 2006(Washington, DC, 2005)This year’s Word Development Report (WDR), the twenty-eighth, looks at the role of equity in the development process. It defines equity in terms of two basic principles. The first is equal opportunities: that a person’s chances in life should be determined by his or her talents and efforts, rather than by pre-determined circumstances such as race, gender, social or family background. The second principle is the avoidance of extreme deprivation in outcomes, particularly in health, education and consumption levels. This principle thus includes the objective of poverty reduction. The report’s main message is that, in the long run, the pursuit of equity and the pursuit of economic prosperity are complementary. In addition to detailed chapters exploring these and related issues, the Report contains selected data from the World Development Indicators 2005‹an appendix of economic and social data for over 200 countries. This Report offers practical insights for policymakers, executives, scholars, and all those with an interest in economic development.
