This article investigates the effects of information and communication technologies (ICT) on female labor force participation in a sample of 48 African countries. We specify and estimate linear regression and dynamic panel data models with fixed effects (FE) and system-generalized method of moments (SYS-GMM) estimation over the period 2001–2017. The three main results are that ICT use (mobile phone and internet) significantly stimulates female labor force participation in Africa; this effect is enhanced by financial development and female education; the effect of ICT on female employment in Africa is strongest in the industrial sector. These results remain robust to the provision of social, cultural, and institutional variables. 相似文献

We analyze the impact of healthcare financing on economic growth, focusing on the issue of the joint public–private financing of healthcare (co-payment). We use an overlapping-generations model with endogenous growth based on health human capital accumulation, where families pay for childhood preventive care and the government can either fully finance or co-finance adulthood curative care. From a growth maximizing perspective, distortionary taxes give an advantage to co-financing. Nevertheless, we prove that, if agents are assumed to be heterogeneous in preferences, full financing can become the best option. 相似文献

We exploit within-school variation in counselors and find that one additional counselor reduces student misbehavior and increases boys’ academic achievement by over one percentile point. These effects compare favorably with those of increased teacher quality and smaller class sizes. 相似文献

The financial disintermediation mechanism known as “loan-based-crowdfunding” has recently come under regulation in several countries. This competitive investment and finance vehicle is already well established in the US and British markets.By compiling empirical data from a reference crowdfunding platform, this article compares loan-based crowdfunding with traditional investment vehicles such as investment funds, equities or pension funds.The conclusion of the study is that saving through crowdfunding allows the optimization of a portfolio comprising both institutional and retail investors. 相似文献

This paper presents an analysis of the 2007-2010 Global Financial Crisis which started with the sub-prime crisis in the U.S. and became global very fast. It argues that the financial system in the United States is a complex interlocking structure of markets, institutions and regulators. The causes and culprits of the crisis, the misaligned incentives of participants and exogenous events such as the wars in Afghanistan and Iraq, precipitated failure in key markets: commodities, sub-prime housing, equities, and credit. One of the strategic consequences of this crisis is that the US will lose its dominance in world power, the frequent crises and vulnerabilities of the Neoliberalism and examines the future of capitalism. Of the alternatives to economic system, the capitalism is the most viable economic system. However, it must adopt real and efficient allocation of resources to maximize welfare of all parties and seriously address the income inequality. It must reject crony capitalism, enact true financial regulation of institutions and markets, end corporate socialism and address the system’s structural deficiencies. 相似文献

This paper examines traditional Islamic school (i.e. madrasah) attendance as a determinant of social attitudes among secondary-schooled adolescents in rural Bangladesh. Although both recognized and traditional madrasah-enrolled adolescents show greater support for charity, we find no evidence that traditional madrasah attendance promotes “trust in others”. Attendance at recognized madrasahs, which use a state-approved curriculum, however, significantly increases social trust. The madrasah–trust connection is not explained by the role of teachers’ attitudes towards trust or professional background. Nor do we find evidence that the absence of an effect of traditional madrasah attendance on social trust is driven by their geographic locations. Given the differences between the two groups in terms of stated social preferences, our analysis warns against the practice of lumping state-recognized madrasahs and traditional madrasahs into one category. 相似文献

Childcare is not like other goods and services. Its inherent nature creates unusual challenges for efficient delivery by the market, while its usage can have social as well as private consequences. Government involvement in childcare may therefore be justified to improve the efficiency of delivery or achieve social objectives, but its effectiveness will depend on whether policy measures can better address the challenges of childcare provision than the market. This article reviews the justification for the recent rapid development of childcare policy in the UK and considers the potential benefits and drawbacks of this growing government intervention. 相似文献
