Despite of significant growth in all walks of life, the issue of infant mortality still a major concern in most of the developing economies. The World Development Indicators have reported that 4.45 million infants died across the globe in 2015, meaning that 32 deaths per every 1,000 live births. A number of times, the World Health Organization (WHO) have stressed the significance of sanitation, safe drinking water and healthcare facilities in reducing infant mortality rate, though most developing countries still lacks in these services. Given this background, the present study aims to examine the role of sanitation, water facilities and health expenditure on infant mortality rate across a panel of 84 developing economies using annual data from 1995 to 2013. The study also account for per capita income and depth of food deficiency as the control factors in the model. The findings of this study establish a significant long-run equilibrium association among the variables. The long-run elasticities on infant mortality suggest that improved water and sanitation facilities, health expenditure and per capita income substantially reduce infant mortality rate, while food deficiency increases. Given these findings, we suggest that increasing access to improved water, sanitation and healthcare facilities will significantly reduce child mortality in developing economies around the world. 相似文献

We estimate that prenatal care has positive impacts on health measured at birth, shifts the distribution of future health care utilization away from inpatient care, and find that some of these impacts likely come from an informational mechanism. We also find well child visits are used in a complementary fashion with emergency department care in the production of infant health, suggesting that factors beyond barriers to access may drive the demand for emergency care. Finally, we find differential impacts of prenatal care across racial groups with evidence that the information mechanism may be particularly important for black mothers. 相似文献

Environmental justice and enforcement of the safe drinking water act: The Arizona arsenic experience
Environmental justice is concerned with the fair treatment and meaningful involvement of all people regardless of race, color, national origin, or income with respect to the development, implementation, and enforcement of environmental laws, regulations, and policies. A wide variety of empirical studies have concluded that disparate-impact discrimination does in fact exist since minority and low-income communities are at disproportionate risk for environmental harm. In this paper we examine these issues in the context of enforcing the safe drinking water act (SDWA). Specifically, we focus on the association between race, income, and hazardous levels of arsenic concentration and analyze the broad equity implications of implementing the new arsenic regulation by examining the relationship between community-level exposure to arsenic and socioeconomic and demographic characteristics of the population in Arizona. The results provide no support for the contention that continued selective implementation and enforcement of the revised SDWA arsenic standard is likely to disadvantage minority or low-income groups disproportionately in Arizona. 相似文献

This paper describes the application of the contingent valuation (CV) or willingness to pay (WTP) survey technique to a problem of public policy evaluation in Seoul, Korea. Matters of principal interest include: the definition of the problem and policy — protection of Seoul's drinking water supply from disruption by slugs of contaminants in the source river (the Han); adjustments to standard CV techniques and assumptions required by the cultural and physical reality of Seoul; the representativeness of the spatially-drawn sample; estimation of the willingness to pay equation as a check on theoretical validity; and the policy implications of the results. The bottom line is asserted to be that CV may be especially valuable in countries such as Korea that have serious environmental problems and a history of not producing data that might be used in alternative (indirect) benefit estimation exercises. Further, it appears that if care is exercised in adjusting to local reality, the method can be made as successful as it has been in the U.S. and northern Europe.Assoc. Res.

Forest land use is often associated with the protection of water resources from contamination and the reduced cost of drinking water supply. This study attempted to measure the value of the forest on the quality of water resources from a contingent market, namely drinking water supply, by estimating variations in drinking water costs as a function of variations in land uses. Spatial correlations were taken into account because of the use of different geographical scales (i.e., water service area and land uses) and the potential existence of organizational and technological spillovers between water services. We found a significant negative effect of forest land use on water costs. We found no evidence of spatial spillovers concerning the management regime but did find that factors related to the scarcity of resources in neighboring water services have an impact on water costs. 相似文献

We examine the impact of piped water on the under-1 infant mortality rate (IMR) in Brazil using a recently developed econometric procedure for the estimation of quantile treatment effects with panel data. The provision of piped water in Brazil is highly correlated with other observable and unobservable determinants of IMR — the latter leading to an important source of bias. Instruments for piped water provision are not readily available, and fixed effects to control for time-invariant correlated unobservables are invalid in the simple quantile regression framework. Using the quantile panel data procedure in Chen and Khan [Chen, S., Khan, S., Semiparametric estimation of non-stationary censored panel model data models with time-varying factor. Econometric Theory 2007; forthcoming], our estimates indicate that the provision of piped water reduces infant mortality by significantly more at the higher conditional quantiles of the IMR distribution than at the lower conditional quantiles (except for cases of extreme underdevelopment). These results imply that targeting piped water intervention toward areas in the upper quantiles of the conditional IMR distribution, when accompanied by other basic public health inputs, can achieve significantly greater reductions in infant mortality. 相似文献

To what extent do differential levels of investment in public health inputs explain observed differences in health outcomes across socioeconomic and racial groups? This study investigates the impact of 3700 projects that were part of a widespread Federal initiative to improve sanitation infrastructure on U.S. Indian reservations starting in 1960. Sanitation investment substantially reduced the cost of clean water for households, leading to sharp reductions in both waterborne gastrointestinal disease and infectious respiratory disease among Native American infants. The sanitation program was quite cost-effective, in part because improvements in the overall disease environment also reduced infectious respiratory disease among nearby White infants. Despite the health externalities, Federal sanitation interventions explain almost forty percent of the convergence in Native American and White infant mortality rates in reservation counties since 1970. 相似文献

In this paper, we investigate the impact of access to drinking water sources and sanitation facilities on the incidence of diarrheal diseases among children below 5 years of age in Ethiopia using the propensity score matching technique with a polychotomous treatment variable. We find that among the water sources traditionally considered as improved, only water piped into dwelling, yard or plot leads to a large percentage point reduction in diarrhea incidence. The other water sources, generally believed as clean, are not effective in reducing diarrhea even compared with some of the unimproved water sources. We also find that some unimproved water sources and sanitation facilities are less inferior than they are believed to be. These results suggest that the traditional way of categorizing different types of improved and unimproved water sources and sanitation facilities into a dichotomous variable, “improved” or “unimproved”, could be misleading as it masks the heterogeneous effects of the water sources and the sanitation facilities. 相似文献

Prior research suggests that the availability of abortion services may affect the proportion of observed births with poor
outcomes (e.g., low birth weight). Recent Supreme Court decisions and changes in the composition of elected officials of state
governments have increased the saliency of state discretion over abortion related policies. This paper presents results from
a simulation model of the effects of hypothetical state laws prohibiting abortion on observed measures of infant health in
the states regarded as most likely to adopt laws significantly restricting abortion access. Under several model scenarios,
both the incidence of low birthweight infants and neonatal mortality among blacks are predicted to increase substantially
in states adopting restrictive abortion laws. The predicted impact among whites, however, is relatively small.

Untreated or partially treated wastewater, which is a negative externality of urban water use, is widely used for irrigation in water scarce regions in several countries including India. While the nutrients contained in the wastewater is considered as beneficial to agriculture, the contaminants present in it pose environmental and health risks. This paper examines the morbidity status, its determinants as well as the cost of illness for households living in the areas irrigated with wastewater in comparison with those using normal quality water. Primary data collected from six villages irrigated with wastewater along Musi River which is fed with wastewater and one control village where normal quality water is used for irrigation has been used for the analysis.It is seen that higher rates of morbidity exist in the wastewater irrigated villages when compared to the control village. Specifically, adult and female morbidity rates are significantly higher than child and male morbidity rates. From the logit analysis it is seen that exposure to wastewater and engagement in activities based on it places the households in higher risk groups to report morbidity. Small and marginal farmers incur higher economic cost of illness. However, it has been difficult to ascertain the cause and effect relationship as most of the households have reported more common illnesses like fever, head ache, skin itching, stomach ailments, etc. The study points out the need for a comprehensive risk assessment and adoption of risk management measures including setting standards for treatment and discharge of wastewater and regulations on the type of uses etc. to prevent unplanned use of untreated or partially treated wastewater while taking into account local conditions. 相似文献

"民间执业,全以契券为凭",这句话有一定道理,但并非绝对正确.明清时期,判断田宅所有权的标准除了契券以外,还有户帖或土地执照、黄册或土地册籍、粮串、买卖田宅时的中人或其他签押人甚至地邻、佃户的证明.就契券来说,也必须是无瑕疵的契书.民间和官方通常通过多种证据证明田宅的归属.明清时期,田宅的归属大致是明晰的,田宅的流转基本上是安全的. 相似文献

The author contends that birth rate and infant and child mortality rates are jointly determined by demographic, economic, health care, and other influences. Working under this structural assumption, a multiequation model is developed, estimated, and simulated, in which real earnings, unemployment, midwife visits, access to cheap energy, public health expenditures, and degree of urbanization are determinant factors of declining infant and child mortality in Chile. Most notably, mortality declined during a period of increasing unemployment and falling living standards for at least part of the population. The study found all 3 rates to be jointly determined, but by different variables. Specifically, unemployment affected birth rate and child mortality rate, while declining infant mortality was based upon midwife visits, health expenditure, and access to cheap energy. At the policy level, trade-offs often result between infant and child mortality, especially where high birth rates prevail. Where movement along the Phillips curve is possible, higher earnings should be preferred over lower unemployment for the benefit of infant and child mortality. Preferred policy would week to provide a carefully balanced combination of better earnings and more midwife visits. 相似文献

Recently, Australia's two largest brewers, Carlton and United Breweries and Lion Nathan, have been aggressively competing for market share in the state of Victoria. Among other strategies, the two breweries have implemented vertical restraints in the form of?‘extensive’?agreements with retailers and the outright purchase of pubs. A key outcome of these purchases and agreements is the renovation of many pubs as brewers attempt to attract increasingly sophisticated drinkers. This paper attempts to quantify the value of these renovations and measure their associated impact on consumers, relying on insights from the hedonic literature. A simple, but novel approach, is used to estimate the implicit price of the pub environment and the effects of renovations on that price. 相似文献
