We first provide a nonparametric inference of the relationship between life expectancy and economic growth using historical data for 18 countries over the period 1820–2005. The obtained shape indicates convexity for low enough values of life expectancy and concavity for large enough values. We then study this relationship using a benchmark model combining \"perpetual youth\" and learning-by-investing. The generated relationship between life expectancy and economic growth is shown to be strictly increasing and concave. We finally examine two models departing from \"perpetual youth\" by assuming successively age-dependent earnings and age-dependent survival probabilities. With age-dependent earnings, the obtained relationship is hump-shaped, whereas age-dependent survival laws reproduce the convex–concave shape detected in prior empirical study. 相似文献

This study empirically assesses the relationship between mothers’ education and child health using continuous and binary proxies of child health outcomes. A panel, using four waves of the National Income Dynamic Study and a battery of estimation techniques, was employed. The results suggest that maternal education plays a large and significant role in explaining child health outcomes in South Africa. Our results also suggest that maternal education is relevant in respect to stunted growth (stunting). However, the effects of maternal education vary along races, implying levels of inequality. The effects are stronger in the black and coloured populations, possibly due to educational deficits. This suggests a need in improving the educational opportunities for these groups. We suggest that maternal education can significantly contribute to reducing the high degree of inequality in South Africa. 相似文献

The expected increase in aid to Africa will put a big challenge for public service delivery. This paper provides an analysis
of the effects of the volume and volatility of aid on education, health, water and sanitation outcomes, taking also into account
the institutions related to public service delivery, including freedom of press, corruption, and decentralization, using a
simultaneous equation model. Overall the share of Official Development Assistance (ODA) that is provided for education and
health seems to have a positive impact on outcomes in these sectors, whereas total aid seems to be negatively associated.
Aid volatility is associated with better outcomes in sanitation, water, and infant mortality, contrary to expectations.

The Russian Empire had the highest infant mortality rate in Europe at the beginning of the twentieth century. Using a variety of official statistical sources and qualitative evidence, this paper documents uniquely high infant mortality among ethnic Russians. In contrast, among other ethnic groups of the empire, infant mortality rates did not exceed those of the European countries by much. The evidence suggests that the explanation for the Russian infant mortality pattern was ethnic-specific infant care practices, such as the early introduction of solid food, which increased the incidence of lethal gastrointestinal diseases. Our findings highlight the importance of traditional infant feeding practices in mortality in pre-industrial societies. 相似文献

现行的中国养老保险制度是"统筹账户和个人账户"相结合的部分积累模式。其中,个人账户不具备代际内收入再分配的功能,属于私人商品。个人账户缴费率的高低不仅影响到个人当期的可支配收入,而且间接影响到其退休后生活水平的高低。现行养老保险制度下的个人账户缴费率只能保障退休人员10年的生活,而目前男女退休职工的算术平均余命已接近17年,因此,随着人均寿命提高且不断延长,如果不能及时调整个人账户缴费率,那么退休人口将面临着因长寿带来的生活无保障的情况。本文则通过以现有的理论研究为基础进行合理测算,力求得出基于人均寿命提高调整个人账户缴费率的理论依据和政策依据。 相似文献

Closing the gender gaps in economic opportunities is crucial for boosting economic growth and the empowerment of women. In this paper, we study how foreign firms contribute in reducing gender disparities in the labour market by transferring the gender norms of their country of origin to the affiliates in the host countries. We use cross sectional data on foreign firms located in 19 Sub Saharan Africa countries in 2010 by UNIDO. We find that firms coming from more gender equal countries employ more female workers in their affiliates. This effect is more relevant for the highly skilled female workers. 相似文献

This paper explores which African countries had relatively low rates of underweight children and relatively high birth coverage (percentage of births with a skilled attendant) in the poorest quintile. Swaziland and Rwanda emerged as relatively ‘pro-poor’ in that both measures were more than one standard deviation better than predicted by GDP per capita. Unlike Swaziland, Rwanda’s status as an outlier was eliminated in regressions controlling also for urbanisation, medical professionals per 1000 people and health spending, suggesting that its pro-poor outcomes were related to these factors. AIDS funding may have helped Swaziland provide primary health care to the poor, but its high birth coverage preceded the HIV epidemic. Although relatively pro-poor in international terms, Swaziland and Rwanda emerged as relatively unequal by the CIX measure of health inequality with regard to percentage of underweight children across quintiles. It is important not to conflate relatively equal with relatively pro-poor health outcomes. 相似文献
