Abstract: The present paper assesses the relative roles of internal and external factors in the decline of groundnut trade by AGC countries. Furthermore, it analyses the determinants of regional vegetable oils demand and evaluates the extent to which regional exporters can benefit from the rapid expansion of demand on regional markets. Résumé: Ce document cherche à déterminer le rôle relatif des facteurs internes et externes dans le fléchissement du commerce de l'arachide entre les pays de l'AGC. Par ailleurs, son auteur analyse les causes détermhantes de la demande régionafe des huiles végétales et cherche àévaluer dans quelle mesure les exportateurs régionaux peuvent profiter de l'expansion rapide de la demande sur les marchés de la région  相似文献

This study develops two-level hierarchical model that identifies factors that favor or hamper the use of Internet in Africa. We used data from a survey covering 17 African countries. Our results confirm that urbanization and the spread of Internet infrastructures play an important role in individual decisions to adopt this technology. They also reveal that an individual will have a larger probability to use Internet if he/she has at least completed primary education.Moreover, individual characteristics such as sex, age, level of education, and a social network membership greatly influence Internet adoption. Indeed, men are more likely to use Internet than women; this probability is larger if they are young (16–30 years old) or if they attained at least secondary education level or if they are members of a social network.  相似文献

The Substitutability of Real Estate Assets   总被引:4,自引:0,他引:4  
This paper investigates the degree of substitutability between securitized real estate assets and real estate assets whose prices are appraisal-based. Given the insensitivity of unsecuritized asset's returns to the returns on stock market indices, equilibrium asset pricing models cannot be used to compare these two avenues of investment. Two assets are deemed substitutable if the information sets underlying unbiased, minimum error variance estimates of their pricing parameters are identical. The empirical evidence shows that the prices of the transactions-based assets—real estate investment trusts and the stock price index of the home building industry—follow a random walk while the prices of the appraisal-based assets—FRC/NCREIF indices—do not. The variance decompositions of the vector autoregressions also show that the level of economic activity helps predict the price indices of appraisal-based assets while the stock market index and the term structure of interest rates are better predictors of the prices of transactions-based assets  相似文献

We apply parametric and nonparametric methods to data from smallholders in Burkina Faso and assess the role that human capital characteristics play in the agricultural production process. Our results point to the technology‐changing nature of health, education, and experience. However, effects are rather heterogeneous. The productivity elasticity of health is much larger for households in the lowest landholding quintiles, while returns to experience are larger for households in the upper quintile. In terms of policy implications, our results suggest that productivity can be stimulated through the allocation of expenditure to social services that enhance certain types of human capital. Interventions aimed at improving the health status of households with smaller landholdings could have particularly strong welfare effects.  相似文献

While it is widely recognized that agricultural research is a key driver of broad-based technological change in agriculture that benefits the poor in many different ways, little is known about its aggregate impacts on productivity growth and poverty reduction in sub-Saharan Africa (SSA). Using a polynomial distributed lag structure for agricultural research within a simultaneous system of equations framework, this paper first demonstrates that agricultural research contributes significantly to productivity growth in SSA. Productivity growth is again shown to raise per capita incomes, with income increases finally having significant poverty-reducing effects. With an aggregate rate of return of 55%, the payoffs to agricultural research are also impressive. Agricultural research currently reduces the number of poor by 2.3 million or 0.8% annually. While the actual impacts are not large enough to more than offset the poverty-increasing effects of population growth and environmental degradation, the potential impacts of agricultural research are far greater. Apart from low research investments, SSA faces several constraints outside the research system that hinder realization of potential research benefits. The results show that doubling research investments in SSA would reduce poverty by 9% annually. However, this would not be realized without more efficient extension, credit, and input supply systems.  相似文献

Promoting youth and female entrepreneurship is crucial to inclusive growth and the future economic and social prospects of developing countries. Evidence tends to suggest that young and female entrepreneurs are in a minority, and the extent and generating mechanisms of this outcome tend to be country‐specific. This collection of papers brings together recent empirical contributions exploring key drivers of this heterogeneity entrepreneurial propensity of youth and female in the context of a group of countries in Africa, Latin America, and the Middle East, paying special attention to the role of and issues relating to access to credit, attitudes to risk, and migratory status. A common thread in all the papers is the effective role of risk, uncertainty, and asymmetric information in the determination of entrepreneurship and in the demand for and allocation of credit when potential entrepreneurs are from specific groups, that is, women, indigenous women, women and youth in conflict and post‐conflict situations, and migrant youth. Based on these results, the papers explore various challenges in the implementation of public policies designed to promote entrepreneurship within these specific segments of the population.  相似文献
