We examine student, teacher, and peer perceptions of effort, ability, performance, and self-confidence in Romania's highly tracked schools. We find that: (1) students just above a cutoff—tracked into high-achieving classes—have less favorable self-perceptions than those just below (“big-fish-little-pond” effects); (2) students perceive peers in the...

Romanian households could choose schools with one standard deviation worth of additional value added. Why do households leave value added “on the table”? We study two possibilities: (i) information and (ii) preferences for other school traits. In an experiment, we inform randomly selected households about schools' value added. These households choo...

The 1966 abolition and 1989 legalization of abortion in Romania immediately doubled and decreased by about a third the number of births per month, respectively. Comparing birth month cohorts born on either side of the reform cut-offs allows us to cleanly identify the effect of abortion access on crime. For both the abolition and legalization of abo...

Using a compiled dataset of 441 censuses and surveys between 1787 and 2015, representing 103 countries and 51.4 million mothers, we find that: (1) the effect of fertility on labour supply is typically indistinguishable from zero at low levels of development and large and negative at higher levels of development; (2) the negative gradient is stable...

This paper explores the role of parental information and control on children's internet use in Chile. We designed and implemented a randomized experiment whereby 7700 parents were sent weekly SMSs messages that (i) provided specific information about their children's internet use, and/or (ii) offered assistance with the installation of parental con...

We study issues related to external validity for treatment effects using over 100 replications of the Angrist and Evans (1998) natural experiment on the effects of sibling sex composition on fertility and labor supply. The replications are based on census data from around the world going back to 1960. We decompose sources of error in predicting tre...

Educating for economic rationality The hypothesis that education enhances economic decision-making has been surprisingly underexplored. Kim et al. studied this question using a randomized control trial in a sample of 2812 girls in secondary schools in Malawi. Four years after providing financial support for a year's schooling, they presented the su...

We derive a formal, decision-based method for comparing the performance of counterfactual treatment regime predictions using the results of experiments that give relevant information on the distribution of treated outcomes. Our approach allows us to quantify and assess the statistical significance of differential performance for optimal treatment r...

We investigate the external validity of local average treatment effects (LATEs), specifically Angrist and Evans’s use of same sex of the two first children as an instrumental variable for the effect of fertility on labor supply. We estimate their specification in 139 country-year censuses using Integrated Public Use Microdata Sample–International d...

We study issues related to external validity for treatment effects using 166 replications of the Angrist and Evans (1998) natural experiment on the effects of sibling sex composition on fertility and labor supply. The replications are based on census data from around the world going back to 1960. We find that macro covariates dominate over micro co...

Objectives Our objectives were to analyse the effects of text messaging versus usual care in improving adherence to antiretroviral therapy (ART) in people living with HIV using individual patient data meta-analysis. Adjusted, sensitivity and subgroup analyses were conducted. Setting 3 randomised controlled trials conducted between 2010 and 2012 in...

HIV counseling and testing services(2) play an important role in HIV treatment and prevention efforts in developing countries. Community-wide testing campaigns to detect HIV earlier may additionally impact community knowledge and beliefs about HIV. We conducted a cluster-randomized evaluation of a home-based HIV testing campaign in western Kenya an...

Mobile phone text messaging is emerging as an important tool in the care of people living with HIV; however, reports diverge on its efficacy in improving adherence to antiretroviral therapy (ART), and little is known about which patient groups may benefit most from phone-based adherence interventions. We will conduct an individual patient data meta...

Absenteeism of health workers in developing countries is widespread with some estimates indicating rates of provider absence of nearly 40% (Chaudhury et. al. 2006). This is the first paper to present evidence of the impact of health provider absence combined with limitations in health clinic protocol on health outcomes. Using longitudinal data from...

Background: Measurement of adherence to antiretroviral therapy (ART) by patient self-report is common in resource-limited settings but widely believed to overstate actual adherence. The extent to which these measures overstate adherence has not been examined among a large patient population. Methods: HIV-infected adult patients in Kenya who init...

This article addresses the question of whether incumbents can buy political support through targeted public spending. Using a regression discontinuity approach which takes advantage of the design of a recent Romanian government program that distributed coupons worth 200 Euros to poor families towards the purchase of a computer, we find that program...

We estimate changes in sexual behavior for HIV-positive individuals enrolled in an AIDS treatment program using longitudinal household survey data collected in western Kenya. We find that sexual activity is lowest at the time that treatment is initiated and increases significantly in the subsequent six months, consistent with the health improvement...

This paper uses a regression discontinuity design to estimate the effect of home computers on child and adolescent outcomes by exploiting a voucher program in Romania. Our main results indicate that home computers have both positive and negative effects on the development of human capital. Children who won a voucher to purchase a computer had signi...

This paper: i) estimates the effect that going to a better school has on students' academic achievement, and ii) explores whether this intervention induces behavioral responses on the part of children, their parents, and the school system. For the first task, we exploit almost 2,000 regression discontinuity quasi-experiments observed in the context...

There is limited evidence on whether growing mobile phone availability in sub-Saharan Africa can be used to promote high adherence to antiretroviral therapy (ART). This study tested the efficacy of short message service (SMS) reminders on adherence to ART among patients attending a rural clinic in Kenya. A randomized controlled trial of four SMS re...

We characterize medium and long-run labor market impacts of HIV/AIDS and ARV treatment using unique panel data of worker absenteeism and information from an AIDS treatment program at a large mining firm in Botswana. We present robust evidence of an inverse-V shaped pattern in worker absenteeism around the time of ARV treatment inception. Absenteeis...

This paper investigates the effect of the supply of birth control methods on fertility behavior by examining Romania’s 23-year period of pronatalist policies. Following the lifting of the restrictions in 1989 the immediate decrease in fertility was 30 percent. Women who spent most of their reproductive years under the restrictive regime experienced...

This paper examines the relative benefits of general education and vocational training during Romania's transition to a market economy. We examine a 1973 educational reform that shifted a large proportion of students from vocational training to general education. Using census and household survey data, we analyze the effect of this policy with a re...

In December 1989, following the fall of communism in Romania, the ban on access to abortion and birth controls methods was lifted. This paper attempts to analyze the educational achievements of children affected by the lift of this ban, using administrative data of secondary school admission exam scores and placement outcomes. We find robust eviden...

This paper examines the relative benefits of general education and vocational training in Romania, a country which experienced major technological and institutional change during its transition from Communism to a market economy. To avoid the bias caused by non-random selection, we exploit a 1973 educational reform that shifted a large proportion o...

When students are tracked into vocational and academic secondary schools, access to higher education is usually restricted to those who were selected into the academic track. Postponing such tracking may increase the relative educational attainment of disadvantaged students if they have additional time in school to catch up with their more privileg...

This paper examines the impact of having access to a home computer on child and adolescent outcomes. To avoid the bias due to non-random access to home computers, we exploit a unique government program which provided vouchers towards the purchase of a personal computer for low-income children enrolled in Romanian public schools. Since the fixed num...

The paper analyses the relationship of tax compliance costs and business strategy. Due to instruments, like information technology, simplified cash accounting or outsourcing compliance activities to tax advisers, private businesses have a set of strategies to optimize their tax compliance cost burden. Under the assumption of rational choice a priva...

This study examines educational and labor outcomes of children affected by a ban on abortions. I use evidence from Romania, where in 1966 dictator Nicolae Ceauescu declared abortion and family planning illegal. Birth rates doubled in 1967 because formerly abortion had been the primary method of birth control. Children born after the abortion ban at...

Vocational training and general education are the two predominant forms of secondary schooling around the world. Most studies that compare the effect of vocational and general education on labor market outcomes in the cross-section suffer from selection bias since less able students are more likely to enroll in vocational programs. This paper explo...

In the Anglo-American constitutional tradition, judicial checks and balances are often seen as crucial guarantees of freedom. Hayek distinguishes two ways in which the judiciary provides such checks and balances: judicial independence and constitutional review. We create a new database of constitutional rules in 71 countries that reflect these prov...

Hayek (1960) distinguishes the institutions of English freedom, which guarantee the independence of judges from political interference in the administration of justice, from those of American freedom, which allow judges to restrain law-making powers of the sovereign through constitutional review. We create a data base of constitutional rules in 71...

First Draft -February 2007 This Draft -April 2007 -Please do not cite/circulate Abstract In 2001, the Debswana Diamond Company started the first firm-based program in Africa to provide free ARV treatment to its workforce affected by HIV/AIDS. We link individual health information from the firm's treatment pro-gram to a unique panel dataset of all t...

HIV testing and counseling for pregnant women has been scaled-up in sub- Saharan Africa on the grounds that it enables the delivery of medicines that prevent mother-to-child transmission of the virus and promotes behavioral changes among tested women. This paper uses longitudinal data from a high HIV prevalence region to study the take-up of HIV te...
