This paper characterizes the socioeconomic determinants of child health using height‐for‐age z‐score (HAZ), a long‐run measure of chronic nutritional deficiency. We construct a panel data that follows children between ages 3 and 59 months in 1993 through the 1997 and 2000 waves of the Indonesian Family Life Survey. We use this data to identify the various child‐level, household‐level and community‐level factors that affect children's health. Our findings indicate that household income has a large and statistically significant role in explaining improvements in HAZ. We also find a strong positive association between parental height and HAZ. At the community level, we find that provision of electricity and the availability of paved roads are positively associated with improvements in HAZ. Finally, in comparison to community‐level factors, household‐level characteristics play a large role in explaining the variation in HAZ. These findings suggest that policies that address the demand‐side constraints have greater potential to improve children's health outcomes in the future.  相似文献

A computer-based simulator was used for training operators prior to the start-up of a new fertilizer complex which includes a 1,350-MTPD ammonia plant, two 1,100-MTPD urea plants, and a steam and power generation plant with two 18-MW gas turbines. The simulator offered many benefits, which can be used for continued education of operators and engineering studies.  相似文献

We examine the role of visibility in influencing government resource allocation across a multiplicity of public goods. We show that a “visibility effect” distorts governmental resource allocation such that it helps explain why governments neglect provision of essential public goods, despite their considerable benefits. We show that greater democratization widens the gap in resource allocation between more visible (such as famine prevention) versus less visible (such as malnutrition prevention) public goods, up to an intermediate level of democracy. Beyond this level, this gap decreases. Furthermore, public goods with low visibility are prone to multiple equilibria in resource allocation, with voter expectations being shown to be important.  相似文献

An increasing number of tropical timber‐producing nations have enacted bans on export of logs arguing that this will reduce deforestation, expand downstream wood processing and improve the scale efficiency of domestic processing, create jobs and retain more value‐added nationally. The theoretical literature is clear that trade restrictions are generally welfare reducing (except in special cases such as when there is a potential for an optimal export tax). At best, a log export ban is a second‐best policy tool for reducing deforestation and addressing the associated environmental externalities. In overall terms, the suggestion that log export bans can achieve the objectives expected of them is dubious. However, very little quantitative evidence exists to demonstrate this claim and the paper attempts to address this gap by looking at the economic and environmental impacts of eliminating a log export ban in Costa Rica. The authors argue that eliminating the export ban is Pareto improving and could generate economic gains as high as $14 million per annum with the possibility of relatively modest environmental benefits.  相似文献

This study examines the nature of the relationship between formal agricultural credit and agricultural Gross Domestic Product (GDP) in India, specifically the role of the former in supporting agricultural growth, using state level panel data covering the period 1995–1996 to 2011–2012. The study uses a mediation analysis framework to map the pathways through which institutional credit relates to agricultural GDP relying on a control function approach to tackle the problem of endogeneity. The findings from the analysis suggest that over this period, all the inputs are highly responsive to an increase in institutional credit to agriculture. A 10% increase in credit flow in nominal terms leads to an increase by 1.7% in fertilizers (N, P, K) consumption in physical quantities, 5.1% increase in the tonnes of pesticides, 10.8% increase in tractor purchases. Overall, it seems quite clear that input use is sensitive to credit flow, whereas GDP of agriculture is not. Credit seems therefore to be an enabling input, but one whose effectiveness is undermined by low technical efficiency and productivity.  相似文献

We examine the cumulative impact of early schooling investments on later schooling outcomes using enrollment status and relative grade attainment as short-run and long-run measures of schooling. Using a child-level longitudinal data set from rural Ethiopia, we estimate a dynamic conditional schooling demand function where the coefficient estimate on the lagged dependent variable captures the impact of all previous period schooling inputs and resources. We find that a child who is enrolled in the prior period is 33 percentage points more likely to be enrolled currently. These lagged effects are stronger for girls and for children from higher income households.  相似文献

ABSTRACT

The aim of this study is to provide a better understanding of the factors that explain consumer resistance to smart services from a privacy perspective. To this end, an exploratory qualitative study and a quantitative study were carried out. 653 French consumers answered an online questionnaire regarding smart services in the banking sector. Structural equation modelling was used to test the conceptual model. The findings show that information privacy, the unauthorised secondary use of personal information and perceived intrusion have an impact on consumer resistance to smart services. Moreover, our research highlights the major role of the ‘Big Brother effect’ as an antecedent to these various privacy concerns.  相似文献
