Wars and Child Health: Evidence from the Eritrean-Ethiopian Conflict

Conflict between and within countries can have lasting health and economic consequences, but identifying such effects can be empirically challenging. This paper uses household survey data from Eritrea to estimate the effect of exposure to the 1998-2000 Eritrea-Ethiopia war on children's health. The identification strategy exploits exogenous variation in the conflict's geographic extent and timing and the exposure of different birth cohorts to the fighting. The unique survey data include details on each household's migration history, which allows us to measure a child's geographic location during the war and without which war exposure would be incorrectly classified. War-exposed children have lower height-for-age Z-scores, with similar effects for children born before or during the war. Both boys and girls who are born during the war experience negative impacts due to conflict. Effects are robust to including region-specific time trends, alternative conflict exposure measures, and mother fixed effects.     

Health Expenses: Evidence from the Club Clustering Approach

This paper explores convergence of real health expenses across the Indian states. The new panel convergence methodology developed by Phillips and Sul (Econometrica 75:1771–1855, 2007) is employed. The empirical findings suggest that these states form distinct convergent clubs, exhibiting considerable heterogeneity in the underlying health expenses patterns.     

National Health Insurance and Technology Adoption: Evidence from Taiwan

Generous health-insurance coverage may encourage hospitals to acquire and employ more advanced medical technologies. The authors examine the effects of Taiwan's 1995 implementation of National Health Insurance on technology adoption, ownership, and use by comparing changes in adoption, ownership, and use rates by private hospitals with changes by public nonteaching and public teaching hospitals. Using random-effect panel probit and tobit models, the article finds strong empirical evidence that third-party payment increases the probability of technology adoption, ownership, and use.

Precautionary Savings in Mexico: Evidence From the Mexican Health and Aging Study

Precautionary saving is the additional saving done by individuals to protect them financially in situations of uncertainty and reduce their vulnerability for negative shocks that may affect their consumption levels. This paper investigates the existence and extent of savings motivated by precaution in Mexico for people aged between 50 and 75, using data from the Mexican Health and Ageing Study 2003. The empirical strategy is based on a test of the direct relationship between the accumulated wealth and the uncertainty generated by the social security status, in particular the availability of health insurance, accounting also for the expectation to receive a retirement pension. The endogeneity‐corrected estimates do not yield results that unequivocally support the existence of private savings as a risk protection mechanism, implying that the public protection system has an important role in reducing the vulnerability of the population studied.     

社会支持对老年人健康相关生命质量影响研究——基于南通的实证

应用欧洲五维健康量表(EQ-5D)和社会支持量表(SSRS)分别评价南通市老年人健康相关生命质量和社会支持现状,实证分析社会支持对老年人健康相关生命质量的影响。数据来源于2010年南通市老年人健康与居家养老服务课题调查,包括了377名农村老年人和383名城市老年人。用OLS回归模型估计社会支持对老年人EQ-5D指数得分影响,用Logistic回归模型估计社会支持对老年人生命质量各维度的影响。社会支持显著提高了老年人健康相关生命质量指数得分。政府应该加强老年人社会支持体系的建立,尤其是农村,提高老年人健康相关生命质量,实现健康老龄化。     

Competition and Costs: Evidence from Competitive Tendering in the Scottish National Health Service

This paper estimates the impact of competitive tendering on cleaning costs in Scottish National Health Service hospitals. Unlike previous studies, which have relied on cross‐sectional data, a five‐year balanced panel of 176 hospitals is used to estimate a series of fixed effects regression models. These panel estimates suggest that previous studies have likely over‐estimated the cost‐savings associated with competitive tendering. The findings also suggest that the lower costs associated with competitive tendering have more to do with auction theory than with any intrinsic efficiency of the private sector.     

Social Security Income and Health Care Spending: Evidence from the Social Security Notch

In this paper, I exploit Social Security legislation changes to identify the causal effect of Social Security income on out‐of‐pocket medical expenditures of the elderly. Using the 1986–1994 Consumer Expenditure Survey and an instrumental variables strategy, the empirical results show that health care expenditures are responsive to changes in Social Security income for elderly individuals with less than a high‐school education. The estimated income elasticities are between 1.41 and 3.47, depending on the outcome measures, and are statistically significant at conventional levels. The findings are in contrast to existing studies that find a small income elasticity at the individual/household level.     

Health care expenditure and income in the OECD reconsidered: Evidence from panel data

This paper reconsiders the long-run economic relationship between health care expenditure and income using a panel of 20 OECD countries observed over the period 1971–2004. In particular, the paper studies the non-stationarity and cointegration properties between health care spending and income. This is done in a panel data context controlling for both cross-section dependence and unobserved heterogeneity. Cross-section dependence is modelled through a common factor model and through spatial dependence. Heterogeneity is handled through fixed effects in a panel homogeneous model and through a panel heterogeneous model. Our findings suggest that health care is a necessity rather than a luxury, with an elasticity much smaller than that estimated in previous studies.     

The Impact of Individual Health Account Scheme on Lifetime Income Redistribution: Evidence from China

This paper investigates the effects of a combination of individual health accounts (IHAs) and catastrophic insurance on lifetime income redistribution by examining the variations in end‐of‐life IHA balances and lifetime out‐of‐pocket health expenditures. We exploit longitudinal health expenditure data from 2005 to 2007 in Kunshan City, Jiangsu Province of China. We find a high concentration of low IHA balances at the end of life, with most equal to zero. This finding suggests that most IHA balances are used for health expenditures and that the income redistribution effect through the accumulation of IHA balance is limited. However, the results also show a wide variation in lifetime out‐of‐pocket spending in the form of deductibles and coinsurance, which implies serious inequality in individual financial burden that can lead to a large income redistribution effect.     

Consumption Inequality in China: Theory and Evidence from the China Health and Nutrition Survey

We investigate consumption inequality in China both theoretically by constructing a theoretical model that delineates the transmission channels by which income shocks affect consumption and empirically through an Unequally Spaced Dynamic Panel Data model estimation. We find that China is experiencing consumption inequality with the full partial insurance of consumption against both permanent and transitory income shocks, although the impact of both types of shock are larger than the case of the United States. The results are due to precautionary savings motives of the Chinese. We further document how income becomes more dispersed in China and show how the family background of a child affects his outcome to a large extent. Policy implications based on our findings are proposed.     

非农就业、母亲照料与儿童健康——来自中国乡村的证据

中国农村女性参与非农就业的比例显著提高,对于增进家庭收入、减少贫困起到了积极的作用。但从女性在家庭中的双重身份——挣取收入者和照看孩子的主要人员出发,其劳动模式和供给行为的改变对于下一代福利的影响和人力资本的积累所起到的作用却是不确定的。本文通过将农村地区妇女的劳动供给状况进行区分,就其劳动参与行为对孩童健康状况的影响进行了探讨。在控制其他因素的情况下,母亲额外单位的劳动时间的增加对孩子的健康状况具有显著的负向影响,且同样的母亲非农劳动时间的增加对于孩童健康的负面影响大于农业劳动时间增加的影响程度,而母亲收入增加对孩子健康状况具有显著的正向影响;边际效果分析表明母亲收入增加对孩子健康的正向影响难以抵销劳动时间增加所带来的负面效果。孩子性别不同所受到的影响亦不同,女童相对而言处于健康的劣势地位。虽然母亲的劳动供给有助于缩小孩子营养状况的性别差距,但却是以所有儿童的健康状况下降为代价的。研究结果预期具有较强的政策含义。     

Women's Intrahousehold Decision-Making Power and Their Health Status: Evidence from Rural Ethiopia

ABSTRACT

This study examines how various determinants of women's decision-making power affect their health status in rural Ethiopia. It identifies the determinants of women's decision-making power using a qualitative survey conducted over 2008–9, and it investigates their effects on women's health status using the Ethiopian Rural Household Survey panel dataset for the period 1994–2004. The study finds that women's health status is positively associated with their education, the number of brothers they have, whether they live in their birthplace, and whether their age is close to that of their husband. In contrast, women's health is negatively associated with whether they are in a marriage of their choice compared to an arranged marriage. The study concludes that multiple factors originating from context-specific gender norms affect women's decision-making power and have differential effects on women's health outcomes.     

我国城镇居民的健康需求与Grossman模型——来自截面数据的证据

本文从人力资本的角度用Grossman模型来分析我国城镇居民的健康需求。利用中国健康和营养调查(2000)数据,我们有以下主要发现:(1)与收入的不平等形成对比,城镇居民健康状况的分布比较均衡;(2)女性的教育程度对健康有正的影响,而男性的教育程度对健康的影响不显著;(3)年龄对男性健康的影响比女性大;(4)收入或工资水平对健康的影响不显著。总体而言女性比男性更符合Grossman模型的预测。     

The yield curve and the macroeconomy: Evidence from Turkey

This paper contributes to the literature on the relationship between the yield curve and macroeconomic variables by focusing on an emerging market case: Turkey. The most important result of the paper is that the relationship between the yield curve and macroeconomic variables is significantly affected by the change in monetary policy which is associated with the implementation of inflation targeting (IT) regime. While before the IT regime the yield curve is affected to some extent by macroeconomic variables, after the IT regime, it is mainly driven by macroeconomic variables. We also find that central bank has gained ability to affect the entire yield curve with the IT regime. The other important result is that in addition to inflation and real activities, the exchange rates also play an important role in the yield curve dynamics in Turkey.     

Re-employment after Retrenchment: Evidence from the TCF Industry Study

Industry Commission inquiries into the passenger motor vehicle and textiles clothing and footwear (TCF) industries have focused attention on the employment prospects of workers who are displaced as a result of structural change. The fact that older and less skilled workers face considerable difficulty finding new employment is now widely recognised. In this paper we examine the post-retrenchment outcomes for workers retrenched from jobs in the TCF sector. The method of analysis–discrete-time event history analysis–improves on previous studies of post-retrenchment out-comes because labour market conditions are incorporated into the statistical model, redressing the over-emphasis on supply-side issues that characterise previous research. The analysis shows that local and national labour market conditions are important determinants of employment outcomes. Personal characteristics, household circumstances and ascribed skill are also important as employers use these attributes to filter potential recruits. The analysis suggests that the utility of retraining is variable, enhancing the employability of workers with the best prospects (based on their personal characteristics and skills) before taking up retraining but decreasing the employment chances of those with poorer prospects.     

Correcting for transitory effects in RCTs: Evidence from the RAND Health Insurance Experiment

Temporary randomized controlled trials are susceptible to transitory effects that would not result from a permanent treatment. We find a large and statistically significant “deadline effect”—a surge in spending in the final treatment year—in the RAND Health Insurance Experiment, identified by random allocation to three- or five-year enrolment terms. Participants facing lower coinsurance rates show larger spending surges. Partialing out the price–deadline interaction reduces in magnitude estimates of the permanent price elasticity of drug spending (and in some specifications of outpatient and supplies spending). This implies higher optimal coinsurance rates and illustrates the importance of experimental design to identifying parameters of interest in randomized controlled trials.     

The Czech Labour Market in Transition: Evidence from a Micro Study

In contrast to the other countries in eastern and central Europe, unemployment has so far increased only modestly in the Czech Republic. Results are reported from a panel survey of a sample of initially unemployed workers in the industrial centre of Ostrava, interviewed in three rounds during 1993. Results are reported regarding the wage in the former job, the reservation wage, the wage in a new job and the minimum acceptable wage in another job for those who have become employed during the panel study. Finally, results from estimating a hazard function for leaving unemployment are reported.     

Explaining European Emission Allowance Price Dynamics: Evidence from Phase II

We empirically investigate potential determinants of the allowance price dynamics in the European Union Emission Trading Scheme during Phase II. In contrast to previous studies, we place particular emphasis on the fuel price selection. We show that results are extremely sensitive to choosing different price series of potential determinants, such as coal and gas prices. In general, only the influence of economic activity in Europe and hydropower provision in Norway is robustly explaining allowance price dynamics. The influence of fuel switching on allowance prices and, therefore, equalization of marginal abatement costs – in particular in the long run – is still rather small.     

Health insurance and consumption: Evidence from China’s New Cooperative Medical Scheme

We exploit a quasi-natural experiment arising from the introduction of a health insurance program in rural China to examine how the insurance coverage affects household consumption. Results show that, on average, the health insurance coverage increases nonmedical-related consumption by more than 5%. This insurance effect is observed even in households with no out-of-pocket medical spending. In addition, the insurance effect is stronger in households with worse self-reported health status. These results are consistent with the precautionary savings argument. The insurance effect also varies by household experience with the program. In particular, the effect is significant only in villages where some households have actually obtained reimbursement from the insurance program. The program within these villages stimulates less consumption among new participants than among households that have participated in the program for more than a year.
