Can Mobile Technologies Enhance Productivity? A Structural Model and Evidence from Benin Food Suppliers
This paper analyzes the drivers of digital technologies adoption and how it affects the productivity of small scale businesses in Africa. We use data collected from two semi-rural markets in Benin, where grains and legumes are key staple foods and one-third of the population has internet access. We develop a structural model to rationalize digital technologies adoption—defined as the use of mobile broadband internet connection through smartphones—as well as usage patterns and outcomes observed in the data. The model’s implications are empirically tested using both reduced-form and structural maximum likelihood estimations. We find that younger, wealthier, more educated grains and legum...
The Oxford Handbook of the Economy of Cameroon
Cameroon's suboptimal economic experience since independence (1960) sheds light on broader issues of Africa's development narrative, and provides valuable economic and policy knowledge. While Cameroon's large informal economy is diverse and resilient and rooted in old business traditions, its formal economy has exhibited low productivity and employment growth for over 60 years. This has brought anger, disappointment, and violent conflict in several regions of the country. The Oxford Handbook of the Economy of Cameroon examines the reasons of Cameroon's unsatisfactory economic performance and draws lessons from successful development experience to help tackle these issues. The Handbook provid...
Structural Transformation and the Volatility of Aggregate Output in OECD Countries
This paper finds a negative relationship between the employment share of the service sector and the volatility of aggregate output in the OECD—after controlling for the level of financial development. This result reflects volatility differentials across sectors: labor productivity is more volatile in agriculture and manufacturing than in services. Aggregate output would therefore become less volatile as labor moves away from agriculture and manufacturing and toward the service sector. I examine the quantitative role of these labor shifts—termed structural transformation—on the volatility of aggregate output in OECD countries. I first calibrate to the U.S. economy an indivisible labor m...
Econometric Methods and Their Applications in Finance, Macro and Related Fields
The volume aims at providing an outlet for some of the best papers presented at the 15th Annual Conference of the African Econometric Society, which is one of the OC chaptersOCO of the International Econometric Society. Many of these papers represent the state of the art in financial econometrics and applied econometric modeling, and some also provide useful simulations that shed light on the models'' ability to generate meaningful scenarios for forecasting and policy analysis. Contents: Financial Econometrics and International Finance: Modeling Interest Rates Using Reducible Stochastic Differential Equations: A Copula-Based Multivariate Approach (Ruijun Bu, Ludovic Giet, Kaddour Hadri and M...
Poor Numbers
One of the most urgent challenges in African economic development is to devise a strategy for improving statistical capacity. Reliable statistics, including estimates of economic growth rates and per-capita income, are basic to the operation of governments in developing countries and vital to nongovernmental organizations and other entities that provide financial aid to them. Rich countries and international financial institutions such as the World Bank allocate their development resources on the basis of such data. The paucity of accurate statistics is not merely a technical problem; it has a massive impact on the welfare of citizens in developing countries.Where do these statistics origina...
Energy Subsidies and Public Social Spending
This paper shows that high energy subsidies and low public social spending can emerge as an equilibrium outcome of a political game between the elite and the middle-class when the provision of public goods is subject to bottlenecks, reflecting weak domestic institutions. We test this and other predictions of our model using a large cross-section of emerging markets and low-income countries. The main empirical challenge is that subsidies and social spending could be jointly determined (e.g., at the time of the budget), leading to a simultaneity bias in OLS estimates. To address this concern, we adopt an identification strategy whereby subsidies in a given country are instrumented by the level of subsidies in neighboring countries. Our Instrumental Variable (IV) estimations suggest that public expenditures in education and health were on average lower by 0.6 percentage point of GDP in countries where energy subsidies were 1 percentage point of GDP higher. Moreover, we find that the crowding-out was stronger in the presence of weak domestic institutions, narrow fiscal space, and among the net oil importers.
The Biosphere and Human Society
Human population growth is a serious biospheric problem yet is largely overlooked. Because of the neglect of demography, environmental policies--while well-intentioned--are unlikely to succeed. This book gives a concise review of world fertility rates and population growth, and offers a valuable summary of studies of the impact of over-population on the biosphere. In addition, the book explains key demographic variables to consider when formulating law and government policy relevant to childbearing, and it summarizes findings of social science research--findings that contradict popular assumptions about the impact of government interventions addressing the frequency of childbearing and immigration.
L'industrialisation en Afrique subsaharienne
Génératrice d’emplois et de productivité, l’industrialisation est un vecteur de croissance qui coïncide souvent avec l’accélération du développement dans les économies les plus avancées. Cela étant, du fait de la rapidité des avancées technologiques et des restructurations qu’a connues le commerce international, certains chercheurs et décideurs remettent aujourd’hui en cause les contributions de l’industrie manufacturière au développement dans les Etats où son apparition est tardive. Dans le même temps, l’industrialisation et les transformations structurelles font partie intégrante de l’Agenda 2063 de l’Union africaine et des stratégies de développement ...
L’avenir du travail en Afrique
L‘avenir du travail en Afrique se penche sur deux questions fondamentales : comment créer des emplois productifs et comment subvenir aux besoins des laissés-pour-compte. Le rapport met en lumière comment l’adoption des technologies numériques, conjuguée à d’autres phénomènes mondiaux, transforme la nature du travail en Afrique subsaharienne et pose un défi en même temps qu’elle crée de nouvelles possibilités. Les auteurs montrent que les nouvelles technologies ne sont pas simplement synonymes de destruction d’emplois, comme on le craint généralement, mais qu’elles peuvent permettre aux pays africains de construire un monde du travail inclusif et offrir des opportuni...
Accélérer la réduction de la pauvreté en Afrique
Le redressement de l’Afrique subsaharienne a été spectaculaire au cours des deux dernières décennies. Après de nombreuses années de déclin, l’économie du continent a commencé à reprendre de la vigueur au milieu des années 90. Grâce à cette croissance macroéconomique, la santé de la population s’est améliorée, le nombre des jeunes fréquentant l’école a augmenté, et le taux d'extrême pauvreté a diminué de 54 % en 1990 à 41 % en 2015. La région a connu moins de conflits (en dépit de ceux qui couvent dans certains pays et du nombre inquiétant des personnes déplacées), un élargissement des libertés politiques et sociales, et des progrès dans l’égalité h...
