Abstract
This article questions current empirical practice in the study of growth. It argues that much of the modern empirical growth literature is based on assumptions about regressors, residuals, and parameters that are implausible from the perspective of both economic theory and the historical experiences of the countries under study. Many of these problems, it argues, are forms of violations of an exchangeability assumption that implicitly underlies standard growth exercises. The article shows that these implausible assumptions can be relaxed by allowing for uncertainty in model specification. Model uncertainty consists of two types: theory uncertainty, which relates to which growth determinants should be included in a model; and heterogeneity uncertainty, which relates to which observations in a data set constitute draw from the same statistical model. The article proposes ways to account for both theory and heterogeneity uncertainty. Finally, using an explicit decision-theoretic framework, the authors describe how one can engage in policy-relevant empirical analysis.

Publication The Gambia(World Bank, Washington, DC, 2019-02)Agriculture is a vital sector in the Gambia. It accounts for about 17.8 percent of gross domestic product (GDP), ranking behind the services sector, which recorded 68.8 percent of GDP. Employment in agriculture appears to be mainly driven by women, who are more likely to engage than men. In general, more than two-thirds of Gambians reside in rural areas and derive their livelihoods from agriculture and related activities. Therefore, the sector is a prime area for investment to achieve poverty reduction as stated in the country’s vision 2020 document. Agriculture is an important source of income for households, behind wages and salaries and petty trading. The agriculture sector plays an important role in ending hunger, malnutrition, and extreme poverty. In rural areas, the agriculture sector’s role in poverty reduction and shared prosperity policies is particularly important.Publication Increasing Female Labor Force Participation(World Bank, Washington, DC, 2023-01)Gender gaps in labor force participation persist worldwide. Closing this gap can lead to sizeable gains for economies—a 20 percent increase in GDP per capita, on average. Female labor force participation (FLFP) remains low due to lack of skills, assets and networks, time-based constraints, limited mobility, gender discrimination in hiring and promotion, and restrictive gender norms. Effective evidence-backed policy options can increase FLFP. They include providing childcare services, disseminating information on work opportunities and returns to employment, training in socio-emotional skills, addressing norms by engaging partners and family members, and targeting women via social protection, safety net, and public-works programs. The World Bank Group actively supports countries in boosting FLFP through development policy lending, advisory and analytical work, and supporting reforms to address constraining contextual factors, including legal barriers, social norms, and gender-based violence. This note sheds light on an array of policy options that are effective or show promise in improving FLFP.Publication Business Ready 2024(Washington, DC: World Bank, 2024-10-03)Business Ready (B-READY) is a new World Bank Group corporate flagship report that evaluates the business and investment climate worldwide. It replaces and improves upon the Doing Business project. B-READY provides a comprehensive data set and description of the factors that strengthen the private sector, not only by advancing the interests of individual firms but also by elevating the interests of workers, consumers, potential new enterprises, and the natural environment. This 2024 report introduces a new analytical framework that benchmarks economies based on three pillars: Regulatory Framework, Public Services, and Operational Efficiency. The analysis centers on 10 topics essential for private sector development that correspond to various stages of the life cycle of a firm. The report also offers insights into three cross-cutting themes that are relevant for modern economies: digital adoption, environmental sustainability, and gender. B-READY draws on a robust data collection process that includes specially tailored expert questionnaires and firm-level surveys. The 2024 report, which covers 50 economies, serves as the first in a series that will expand in geographical coverage and refine its methodology over time, supporting reform advocacy, policy guidance, and further analysis and research.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 Wealth Sharing for Conflict Prevention and Economic Growth : Botswana Case Study of Natural Resource Utilization for Peace and Development(World Bank, Washington, DC, 2011-12)There are countries in Asia, Europe, the Middle East and even a few such countries in Africa that are using non-renewable resources to drive development and have not experienced conflict. South Africa, Namibia, Botswana, and Zambia are such typical cases in Africa. Instead, the presence of significant minerals in Botswana is associated with economic development and democracy as well as peace. This paper applies the "resource curse", thesis to the case of Botswana, a country that is rich in minerals, yet it has realized positive development thus avoiding conflict and 'the resource curse'. The focus of this study is to examine the experience of Botswana in using natural resources to promote equitable development and thereby avoid conflict which often results from selfish private or ethnic group interests that elsewhere have used natural resources to the exclusion of other groups in society. This study specifically looks at the conditions and factors that facilitated the absence of internal conflict in the extraction of natural resources in Botswana. The key questions answered are: what contextual conditions and factors facilitated the peaceful extraction of natural resources in Botswana?; and were these factors unique to Botswana or can they be replicated elsewhere?. The first chapter gives introduction. The second chapter deals with the socio-political setting of the chiefs' rule during the pre-colonial and colonial periods. The third chapter discusses Botswana's democracy and how it has evolved not only to democratize society but also to become a management culture of good governance for defining how the natural resources will be utilized for the country's development. Chapter four outlines the mineral resource base of Botswana and the policies and strategies used by government in ensuring that such resources were used for public good rather than the self-interest of either the leaders or mining houses. Chapter five focuses attention on cases of local conflicts relating to mineral and other natural resources around different parts of the country. Chapter six brings the issues together to explain Botswana's democratic and mineral dividends in attaining a high development success rate. Chapter seven presents conclusion.
