地下水污染防治区划研究

地下水在我国水资源体系中占有重要地位,可以直接对我国民众日常生产生活造成影响,在我国社会发展过程中,水资源污染问题日益严重,地下水污染问题成为了社会热门话题之一。基于此,从业人员应加大研究力度,不断对传统治理办法进行创新,以解决地下水污染问题。通过实际工作证明,在现有地下水污染治理策略中,防治区划手段治理效果最好,可以对地下水污染问题进行有效控制,避免地下水污染进一步扩大。     

中国居民家庭收入代际传递性分析

本文通过对父子收入代际弹性和家庭收入代际弹性的研究,发现子女收入很大程度上受到父亲收入或家庭收入的影响,证明了中国居民收入代际之间存在着较为明显的传递效应,特别是低收入群体。通过内外因分析,可以发现教育成为影响中国居民收入代际传递现象的重要因素。教育是一种重要的代际流动机制,个人教育水平提高和教育环境的公平可以使低收入群体有机会流向更高收入阶层。     

Tariffs and Welfare in an Imperfectly Competitive Overlapping-Generations Model

The effect of a tariff is analyzed in a two-sector model in an uncertain-lifetimes framework. One of the sectors is monopolistically competitive. It is shown that while a tariff leads to a consumption boom and possibly a current-account surplus, its welfare effects depend on whether the homogeneous good or the differentiated good is exported by the small open economy. Welfare improves if the differentiated good is nontraded but deteriorates if the homogeneous good is nontraded.

Indian women: well-being and survival

The authors examine sex differentials in sustenance and survival in developing countries using the example of India. Lower female life expectancy at birth and the declining ratio of females to males are discussed as evidence of female deprivation. Consideration is given to the feeding, survival, and neglect of female children, to differences in use of medical facilities by sex, and to regional differences by state. This pattern of discrimination is found to persist even in urban areas.

A testable model of consumption with externalities

This paper presents a nonparametric model of interdependent preferences, where an individual's consumption may act as an externality on the preferences of other consumers. We assume that individual price consumption data is observed for all consumers. It is known that the general consumption model with externalities imposes few restrictions on the observed data, where the consistency requirement is Nash rationalizability. We motivate potential games as an important sub class of games where the family of concave potential games is refutable and imposes stronger restrictions on observed data. We use this framework to extend the analysis of Brown and Matzkin [D. Brown, R. Matzkin, Testable restrictions on the equilibrium manifold, Econometrica 64 (1996) 1249-1262] on refutable pure exchange economies to pure exchange economies with externalities. Finally, we discuss an application of this model to inter-household consumption data.     

Exploiting International Stock Market Correlations with Open-end International Mutual Funds

Investors can exploit the correlations between international stock markets by trading no-load, open-end, international mutual funds. These investors in effect cheat passive investors because they buy the mutual funds at their net asset values, which do not reflect information released during the US trading day. The strategy we examine yields an annual rate of return 800 basis points above the S&P500, over a period of almost eight years.     

Mortality as an Indicator of Economic Success and Failure

Quality of life depends on various physical and social conditions, such as the epidemiological environment in which a person lives. The availability of health care and the nature of medical insurance—public as well as private—are among the important influences on life and death. So are other social services, including basic educa tion and the orderliness of urban living, and the access to modern medical knowledge in rural communities. The statistics on mortality draw our attention to all these policy issues. Mortality information can throw light also on the nature of social inequalities, including gender bias and racial disparities
