How much versus who: which social norms information is more effective?

We conduct an experiment to investigate how different types of information about social norms affect individuals’ stated contributions to a specific pro-environment program, a student ‘green fee’, in the context of a referendum. Compared to students that receive no information about peer contributions, on average, students that receive information about the dollar value range of contributions at peer institutions contribute less while students that learn about the high percentage of students voting ‘yes’ on green fee programs at peer institutions contribute more. The results are economically significant as the absolute values of both effects represent approximately 25% of average contributions. These results suggest that information about participation rates can be more effective than information about dollar amounts in encouraging contributions to environmental initiatives. Of interest to stated preference researchers, we find that results do not change when controlling for self-selection into survey completion.     

Measuring peer effects in the Brazilian school system

Using the identification strategy proposed by Graham and Hahn (2005), we estimate the magnitude of classmate effects on math scores using Brazilian data from 2005. In addition, we provide a detailed discussion about the identification of endogenous peer effects in the linear in means models. Our results show that both peer characteristics (exogenous peer effects) – like race, socioeconomic status and gender – and peer actions (endogenous peer effects) are important determinants of students’ outcomes in the fifth grade of elementary school. Our estimates of endogenous peer effects are about 0.008 of 1 SD of math test scores, which can be interpreted as evidence of a so-called ‘conformist’ individual behaviour, under which students face large costs to exert effort levels that are distant from what is believed to be the norm in the classroom. Those estimates of endogenous peer effects imply a social multiplier of about 1.67.     

Quasi-Experimental Evidence of Peer Effects in First-Year Economics Courses at a Chinese University

The authors of this article implement a quasi-experimental strategy to estimate peer effects in economic education by exploiting the institutional setting in a large public university in China, where roommates are randomly assigned conditional on a student's major and province of origin. They found significant impacts of peer academic quality, measured as roommates’ average scores on the national College Entrance Exam, on first-year economics students’ scores in first-year microeconomics, macroeconomics, and accounting courses. They also found nonlinearity in peer effects: Roommates’ academic ability has significant effects for academically weak students but not for academically strong students.     

Peer group effects on the academic performance of Italian students

We analyse peer effects among students of a middle-sized Italian public university. We explain students’ average grade in exams passed during their Second Level Degree course on the basis of their pre-determined measures of abilities, personal characteristics and peer group abilities. Thanks to a rich administrative data set, we are able to build a variety of definitions of peer groups, describing different kinds of students’ interaction, based on classes attended together or exams taken in the same session. Self-selection problems are handled through Two-Stage Least Squares estimations using as an instrument, the exogenous assignment of students to different teaching classes in the compulsory courses attended during their First Level Degree course. We find statistically significant positive peer group effects, which are robust to the different definitions of peer group and to different measures of abilities.     

Good students,avid readers: The cost of academic success

The effects of reading habits on academic performances have been carefully investigated, but little is known about the effects of academic achievements on students’ leisure reading. This paper investigates this issue by estimating the effects of academic achievements, proxied by the number of exams passed, on leisure reading, measured by the number of leisure books read in a year. Using an online survey submitted to the students at the University of Bologna, Italy, we adopt a two-step control-function technique to control for endogeneity. The empirical evidence suggests the existence of a negative relationship between students’ academic achievements and the time devoted to leisure reading. This result holds for students of different fields of study and is stronger for male students. The Blinder–Oaxaca decomposition supports the existence of a gender-specific idiosyncratic effect.     

Peer heterogeneity,school tracking and students’ performances: evidence from PISA 2006

This paper analyses the interaction between school-tracking policies and peer effects in OECD countries. Using the Programme for International Student Assessment (PISA) 2006 data set, we show that linear peer effects are slightly concave-shaped in both early-tracking and comprehensive educational systems, but generally stronger in the early-tracking one. Second, and more interestingly, the effect of peer heterogeneity goes in opposite directions in the two systems. In both student- and school-level estimates, peer heterogeneity reduces students’ achievements in the comprehensive system while it has a positive impact in the early-tracking one. This reversal effect is robust to different definitions of early-tracking system, to the inclusion of pseudo-school fixed effects and to the exclusion of outlier countries. Finally, peer effects are stronger for low-ability students in both groups of countries.     

Better peers,better scores? A study of twin junior high school graduates in Taiwan

Using data of twin students graduating from junior high schools between 2002 and 2004 in Taiwan, we estimate the effects of peers on high school joint entrance examination performance. To alleviate the potential endogeneity of peer educational achievement, linear models with twin fixed effect and instrumental variables are estimated. Quantile, quantile with twin fixed effect and quantile with instrument variables regressions are also implemented to determine whether estimated peer effects differ at various locations of the testing scores’ conditional distributions. Positive and statistically significant peer effects are found to exist at the mean and at different quantile levels.

Peer effects in medical school

Using data on the universe of students who graduated from US medical schools between 1996 and 1998, we examine whether the abilities and specialty preferences of a medical school class affect a student's academic achievement in medical school and his choice of specialty. We mitigate the selection problem by including school-specific fixed effects, and show that this method yields an upper bound on peer effects for our data. We estimate positive peer effects that disappear when school-specific fixed effects are added to control for the endogeneity of a peer group. We find no evidence that peer effects are stronger for blacks, that peer groups are formed along racial lines, or that students with relatively low ability benefit more from their peers than students with relatively high-ability. However, we do find some evidence that peer groups form along gender lines.     

Can neighbourhoods change the decisions of youth on the margins of university participation?

Abstract This paper uses the Youth in Transition Survey (YITS) to estimate the relationship between neighbourhoods and university participation among Canadian youth. Neighbourhood quality is proxied by the fraction of neighbourhood adults with a Bachelor's degree. The estimated effect is identified using neighbourhood variation within high schools. The paper also tests whether the effects differ by family background and children’s reading skills. Neighbourhoods do not affect university participation among youth drawn from the tails of the socio‐economic distribution. Neighbourhoods have the largest effect on youth drawn from the middle of the socio‐economic distribution who also have above median reading skills.

Peer effects in computer assisted learning: evidence from a randomized experiment

We conduct a large scale experiment to investigate peer effects in computer assisted learning (CAL). Identification relies on three levels of randomization. We find an average 0.17 standard deviation improvement in math scores among primary school students. This average effect is the same for students treated individually or in pairs, implying that peer effects double the learning benefit from a given equipment. Among paired students, poor performers benefit more from CAL when paired with good performers and vice versa. Average performers benefit equally irrespective of who they are paired with. This suggests that the treatment is dominated by knowledge exchange between peers. We also find that CAL treatment reduces the dispersion in math scores and that the beneficial effects of CAL can be strengthened if weak students are systematically paired with strong students.     

Exploring peer effects in education in Latin America and the Caribbean

This paper assesses peer group influence on academic performance of primary school students in Latin America and the Caribbean. Based on TERCE data set, we investigate peer effects in mathematics, language and sciences tests outcomes among sixth grade students. We apply a social interaction model which allows to identify endogenous and exogenous peer effects while controlling for group-level fixed effects. We explore some heterogeneities related to the school type (private, public or rural). The estimates suggest the existence of endogenous peer effects but their magnitude and significance depend on subject and school type.     

It's not your peers,and it's not your friends: Some progress toward understanding the educational peer effect mechanism

Using a new administrative panel data set from the University of Maryland, this paper explores conventional peer effects and the effects of socially proximate peers at a large public university where some students are randomly assigned to housing. Results show that there is little evidence of robust residential peer effects on undergraduate performance. The impact of socially proximate peers' characteristics on student achievement is then examined using an instrumental variables technique. Results indicate that social “friends” do not impact performance more than randomized peers. The paper casts doubt on the notion that social tie formation is the route to peer effects, and urges caution in the continued pursuit of peer effects in education without substantial empirical or theoretical innovation.     

Learning Why More Learning Takes Place in Some Classrooms Than Others

Abstract. The relatively poor average performance of German students on the recent PISA international evaluations of 15- and 16-year-olds' literary skills (2000) and mathematical skills (2003) and the wide variation in performance, with low-income students scoring particularly poorly, have led to calls for reforms of the German educational system. Understanding why students in some classrooms learn more than do those in other classrooms is an important first step in considering alternative reform strategies. Possible explanations include differences in teacher quality, class sizes and peer groups, and also differences among the types of secondary schools that parents select for their children. This paper illustrates a set of techniques that are useful in examining the roles these factors play in predicting why, net of family background and prior achievement, the average achievement of children in some classrooms is much higher than that of children in other classrooms. We illustrate the use of these techniques with a dataset from Bogotá, Colombia, that has two attractive properties. First, some teachers teach multiple classes of students. Second, students are enrolled in schools in two sectors (public and private). Application of the techniques described in this paper could shed light on the reasons why the average academic achievement of German students attending some schools is much higher than that of German students attending other schools.     

The acquisition and labor market value of four English skills: new evidence from NALS

This study investigates the factors related to proficiency in understanding, speaking, reading, and writing English among immigrants using data from the 1992 National Adult Literacy Survey (NALS). It also investigates the earnings-English relationship for each of these four skills to establish which is more valuable in the labor market. English as a Second Language (ESL) courses, education, and years in the United States are found especially to affect English proficiency. Furthermore, the returns on oral proficiency are greater than the returns on literacy skills, although writing skills are more valuable than reading skills. The study concludes that English acquisition is a dynamic process, rather than static as argued by supporters of English-only legislation. An increased role for ESL courses in the acquisition of English is suggested as an alternative policy to English-only laws as long as the marginal cost is less than the marginal benefit.     

Can information and counseling help students from poor rural areas go to high school? Evidence from China

Recent studies have shown that only about two-thirds of the students from poor, rural areas in China finish junior high school and enter high school. One factor that may be behind the low rates of high school attendance is that students may be misinformed about the returns to schooling or lack career planning skills. We therefore conduct a cluster-randomized controlled trial (RCT) using a sample of 131 junior high schools and more than 12,000 students to test the effects of providing information on returns or career planning skills on student dropout, academic achievement and plans to go to high school. Contrary to previous studies, we find that information does not have significant effects on student outcomes. Unlike information, counseling does have an effect. However, the effect is somewhat surprising. Our findings suggest that counseling increases dropouts and seems to lower academic achievement. In our analysis of the causal chain, we conclude that financial constraints and the poor quality of education in junior high schools in poor, rural areas (the venue of the study) may be contributing to the absence of positive impacts on student outcomes from information and counseling. The negative effects of counseling on dropout may also be due to the high and growing wages for unskilled labor (high opportunity costs) in China’s transitioning economy. It is possible that when our counseling curriculum informed the students about the reality of how difficult were the requirements for entering academic high school, it may have induced them to revise their benefit-cost calculations and come to the realization that they are better off dropping out and/or working less hard in school.     

Heterogeneous effects of peer tutoring: Evidence from rural Chinese middle schools

Peer tutoring is a well-known type of peer-assisted learning, which has proven to be a cost-effective intervention. We designed a peer tutoring program that matches high-performing students as tutors to their low-performing classmates and provides non-monetary incentives for them to study together and improve the pair’s academic performance. We implemented the program and tested the effects in rural Chinese middle schools. The program significantly improved the tutors’ math scores and produced other benefits regarding study attitude and social behaviors. However, the program did not improve the tutees’ math scores and instead augmented their learning stress. The most compelling explanation is that the set-up of the program brought to light the tutees’ standing, by design, in the bottom half of their class.     

The economics term paper as an effective teaching tool: Another approach

Summary and conclusion Combining the term paper with the format of a professional conference session provided a learning experience with a lasting positive impact. Students' role playing as chairperson, presenters, and discussants helped to enhance the learning process. Students were motivated go the extra mile not only for peer approval but also because of the impact on their final grade. This approach also helped to develop their oral and written communications skills. These skills are equally relevant for students planning academic and business careers.The presenter-discussant format encouraged critical thinking and provided students with immediate feedback on the success of their efforts. Students who have experienced the process are more knowledgeable about their topic. Most importantly, they are better prepared to succeed at future research projects on other topics.     

基础教育中的同伴效应估计

对基础教育阶段不良同伴带来的短期和中长期效应的评估已经成为劳动经济学的热点话题.文章根据最新的2014年中国教育追踪调查( China Education Panel Survey, CEPS)微观数据,考察了不良同伴对学生标准化考试成绩的影响.为了克服反射(reflection)和自选择问题带来的估计偏误,文章依据班级上不良学生的比例而非传统文献采用的同伴成绩来刻画学生所处的班级环境,并控制了组群的自然特征.在控制学生个体特征和家庭因素后发现,学生所在班级中存在不良同伴,会对学生自身的学习成绩造成显著的负面影响,这一作用在高年级(初三)表现得尤为明显.班级不良同伴比例提高10%会带来平均成绩下降约2分.分样本的回归显示,男性学生、家庭经济状况不佳的学生和住校生的学习成绩对班级不良同伴的反应更敏感.而学校类型的异质性分析则表明,同伴效应在办学情况较差的学校和乡镇/农村学校表现得更明显.进一步的分位数回归结果表明,不良同伴产生的负面效应对成绩较差的学生影响更大.文章的研究发现有利于丰富学界对教育生产函数的认识,也为今后的教育政策提供有益参考.
