Geography,demography, and economic growth in Africa   总被引:2,自引:0,他引:2  
This paper presents the effects of climate, topography, and natural ecology on public health, nutrition, demographics, technological diffusion, international trade and other determinants of economic development in Africa. The goal of this paper is to emphasize the need for intensified research on the issues at the intersection of ecology and human society. Geography was given emphasis because of three reasons: the minimal gain from another recitation of the damage caused by statism, protectionism and corruption to African economic performance; negligence of the role of natural forces in shaping economic performance; and tailoring of policies to geographical realities. The paper also discusses the general problems of tropical development and the focus of Africa's problems in worldwide tropical perspectives; demographic trends in Africa; use of standard cross-country growth equations with demographic and geographic variables, to account for the relative roles of geography; and the future growth strategies and the need for urban-based export growth in manufacturing and services. Lastly, the authors provide a summary of conclusions and discuss the agenda for future research.  相似文献

"This paper uses the 1970, 1980, and 1990 U.S. Censuses to study trends in educational attainment of immigrants relative to natives. Immigrants have become relatively less highly educated, but have become more highly educated in an absolute sense. The effects of changes in relative educational attainment between immigrants and natives on earnings are studied. Educational differences are found to explain more than half the observed wage gap between the two groups. The paper also allows for non-linearities in returns to education. Sheepskin effects influence earnings in different ways for natives and immigrants. Differences in returns to pre- and post-migration education also appear. The paper also finds evidence that immigrants crowd natives out of education, although the effects are stronger in secondary than in postsecondary education."  相似文献

This paper applies the standard Austrian theory of capital investment to the standard interest group model of legislator behavior. Distinguishing between reputational capital and representative capital as interdependent forms of political capital, I argue that legislator behavior (specifically roll call voting) can be explained as entrepreneurial investment in political capital under uncertainty. I discuss several examples in which this approach can potentially add predictive power regarding legislative voting.  相似文献

This research provides empirical support for the hypothesis that learning economics increases a student's critical thinking skills. Using the short form of the Watson-Glaser Critical Thinking Appraisal (WGCTA-S) as our measure of critical thinking skills, we find that students who gain a high level of economic understanding in their introductory economics class, as measured by the Test of Understanding College Economics (TUCE), have statistically significant gains in their WGCTA-S scores. Students who spend more time taking classes and are more fully engaged in the university experience also have greater gains in critical thinking. These results lend support to the idea that introductory economics courses can work in concert with other university level courses, especially within the context of a full-time curriculum, to enhance critical thinking skills.

Millian Efficiency with Endogenous Fertility   总被引:1,自引:0,他引:1  
Should governments implement policies that affect fertility decisions on efficiency grounds? What is the correct notion of efficiency to use? To address these issues, this paper develops an extension of the notion of Pareto efficiency, referred to as Millian efficiency , to evaluate symmetric allocations in an overlapping generations setting with endogenous fertility. This extension is based on preferences of those agents who are actually alive, and exclusively allows for welfare comparisons of symmetric allocations. First, we provide necessary and sufficient conditions to determine whether an allocation is Millian efficient or not, and we show that the sufficient conditions for dynamic efficiency offered by Cass (1972) and Balasko and Shell (1980) cannot be directly applied when fertility decisions are endogenous. Second, we characterize Millian efficient allocations as the equilibria of a decentralized price mechanism, and we present a sufficient condition for dynamic efficiency that uses the sequence of prices associated to such decentralized equilibria. Finally, we analyse how intergenerational policies should be designed to restore efficiency and achieve net welfare gains in two different settings in which markets yield inefficient allocations: dynamic inefficiencies and financial market incompleteness regarding human capital. In the former, a pay-as-you-go social security system eliminates dynamic inefficiencies, provided pensions are explicitly linked with fertility decisions. In the latter, a specific link between social security and public education becomes a necessary condition for Millian efficiency.  相似文献

We present a new model of multi-product firms (MPFs) and flexible manufacturing, and explore its implications in partial and general oligopolistic equilibrium. Globalization affects the scale and scope (or intensive margin and intra-firm extensive margin) of MPFs through a competition effect and a demand effect. The model highlights a new source of gains from trade: productivity increases as firms become "leaner and meaner", concentrating on their core competence; but also a new source of losses from trade: product variety may fall. Our results also hold under free entry, which allows in addition for adjustment along the traditional inter-firm extensive margin.  相似文献

近年来,中国凭借产业集群获得了巨大的国际竞争力。中国产业集群的特点是产量大、劳动密集和生产成本低,其明显缺点是生产效率低、污染严重、附加值低。这些缺点为国外愈演愈烈的对中国反倾销及其它指责提供了口实。中美有各自的优势,两者的合作,将不仅能够促进中国产业集群的转型升级,而且将大大缓解中美间的贸易摩擦。  相似文献
