Child Health in Rural Mexico: Has Progresa Reduced Children's Morbidity Risks?

It is well known that ill health during early childhood can have deleterious consequences for future developmental outcomes. Furthermore, children growing up in poverty are at risk of experiencing frequent and severe episodes of illness because they are highly exposed to the risk factors associated with catching infectious diseases. Progresa, Mexico's main anti‐poverty programme, aims to support and promote parents living in rural areas to invest in children's education, health and nutrition. Poorer unhealthy children in remote rural areas have limited access to health care. This paper investigates whether this rural intervention improved children's health status during its first three years of operation. We examine whether Progresa reduces children's morbidity risks by looking at the changes over time in the incidence of diarrhoea and acute respiratory infections. Additionally, we assess whether there are differential treatment effects according to households’ severity of poverty. The analyses of this study have been carried out using longitudinal data from a randomized treatment and control survey. Our results indicate that there is some evidence that Progresa contributes to reducing morbidity rates. We find that for both diseases under study, the Programme effect is mainly due to a decrease in the morbidity risks of children aged between 24 and 59 months. However, the evidence of a Programme effect is stronger for diarrhoea than for respiratory infections.     

试论淝水之战后陈郡谢氏的盛衰

晋太元八年,东晋军队在谢安、谢石及其子侄的指挥下,获得淝水之战的胜利,东晋朝廷转危为安,陈郡谢氏由此成为晋末最显赫的士族之一。但此后经来自东晋政府上层的抑制,来自下层孙恩、卢循起义的打击,更经宋初改朝换代、皇权重振的冲击,短短的几十年时间里,谢氏家族迅速走向衰落。这一段史实从一个侧面反映了晋宋之际士族的衰落及士庶之间权力交替的过程。

The Impact of 9/11 on the Noncitizen Welfare Caseload: A Time-Series Analysis

ABSTRACT

The tragedy of 9/11 had more far-reaching social and economic consequences for the nation than those found for many individuals on that day. Between October 2001 and May 2002, Nevada witnessed a 25% increase in the total number of households on the Temporary Assistance for Needy Families (TANF) program, commonly referred to as welfare. During the same time, households headed by a noncitizen increased their participation in the TANF program by 40%. This study examines the differential impact of 9/11, as well as of the economy and other external developments, on noncitizen and citizen welfare caseloads in a single state. Two monthly time series models are specified that explain and compare trends in the noncitizen and citizen welfare caseloads from April 1998 to June 2002. The findings suggest that, all else constant, 9/11 had a differential impact on the noncitizen and the citizen caseloads. All else constant, 9/11 events increased the noncitizen welfare caseload whereas a similar impact for the citizen caseload was not found. The findings also strongly suggest that the business cycle shapes noncitizens' participation in public assistance programs more closely than citizens' participation. Future research should investigate the extent to which 9/11 affected the behaviors of families on welfare over the long run.
