Peer effects in Austrian schools

This study deals with educational production in Austria and is focused on the impact of schoolmates on students’ academic outcomes. We use PISA 2000 and 2003 data to estimate peer effects for 15 and 16 year old students. School fixed effects are employed to address the potential self-selection of students into schools and peer groups. The estimations show significant positive effects of the peer group on students’ reading achievement, and less so for mathematics. The peer effect in reading is larger for students from less favorable social backgrounds. Furthermore, quantile regressions suggest peer effects in reading to be asymmetric in favor of low-ability students, meaning that students with lower skills benefit more from being exposed to clever peers, whereas those with higher skills do not seem to be affected much.     

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.     

Patinkin as a reader of Keynes’ General Theory: Are wage cuts a good remedy to unemployment?1

Abstract

This paper analyses Patinkin's appraisal of Keynes’ concept of involuntary unemployment while focusing on his reading of the General Theory Chapter 19. On several critical issues, Patinkin departs from Keynes’ original matters of concerns. He leans against an individual criterion for unemployment and implicitly endorses Wicksell's understanding of voluntary unemployment as chosen leisure. His appraisal of involuntary unemployment as a disequilibrium phenomenon ultimately relies on nominal rigidities and assumes the existence of a competitive adjustment process. On all these three critical points, Patinkin departs from Keynes but also initiates the contemporary New Keynesian programme that went even further from Keynes.     

Are We Spending Too Many Years in School? Causal Evidence of the Impact of Shortening Secondary School Duration

During the last decade, most of the German states have abolished the final year of higher secondary schooling while keeping academic content almost unaltered. We evaluate the effects of the reform in Saxony‐Anhalt for the double cohort of graduates in 2007. In 2003, the 13th year of schooling was eliminated for students in grade 9, while tenth grade students were unaffected. This provides a natural experiment for analyzing the impact on schooling achievements and educational choice. We find negative effects on grades in mathematics, but no effects in German literature. Moreover, a significant share of females were found to delay university enrollment.     

Substitution between leisure activities: a quasi-natural experiment using sports viewing and cinema attendance

The allocation of time between leisure activities and work has been extensively analysed in academic literature. However, leisure time is limited and there may not be sufficient time to enjoy all the leisure activities desired. Hence, this article considers the allocation of time between substitute leisure activities. International football tournaments provide an opportunity to consider consumers’ preferences for watching football and films in a quasi-natural experimental setting. A trade-off between these leisure activities is identified using a difference-in-difference methodology. Using an original, four-country data set, a large and robust negative effect of mega sports events on cinema admissions is identified.     

Migrant peers in the classroom: Is the academic performance of local students negatively affected?

This paper provides the first causal estimates of the impact of internal migrant peers on the academic performance of local students in developing countries. By exploiting the random assignment of students to classes within a school, I find that migrant peers have large and negative effects on the academic performance of local students in China and the negative spillover effects are concentrated among male students and among local students in large cities. The investigation of the underlying mechanisms suggests that the negative migrant spillover effects may come from the worsened learning environment or from the adjustment of teachers’ pedagogical practices in response to the migrant composition in the classroom.     

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.     

Choice of specialization: do peers matter?

Social influence is an important factor in learning and decision-making. We estimate peer influence on student choice of specialization using data on undergraduate students of a Russian university. Information about individual social ties has been gathered from a questionnaire survey. We show that specialization choice is significantly influenced by friends as well as by study partners. The strongest effect is produced by friends who are study partners and those who have similar academic achievements. Reciprocal friendship ties have a stronger influence on the choice than nonreciprocal ones. Also, the decision is affected by classmates with similar academic achievement. The results allow us to better understand the mechanisms of peer effects in the specialization choice.     

Impact of Immigrant Peers on Native Students’ Achievement: Evidence from Australia,Canada and the United States

This article examines how exposure to immigrant students affects the achievement of native students in Australia, Canada and the United States. Variation in the share of immigrant students across different grade levels within schools is exploited to identify the impact of immigrant peers. The study finds that the effects on native students’ achievements of exposure to immigrant peers differ between the three countries. While exposure has a positive impact on Australian natives, it has a negative impact on Canadian natives. Exposure has no effect on US natives. How immigrant students affect their peers is found to depend on institutional arrangements within the education system.     

Natural disasters and university enrolment: evidence from L’Aquila earthquake

Although there are several studies looking at the effect of natural disasters on economic growth, less attention has been dedicated to their impact on educational outcomes, especially in more developed countries. We use the synthetic control method to examine how the L’Aquila earthquake affected subsequent enrolment at the local university. This issue has wide economic implications as the University of L’Aquila made a large contribution to the local economy before the earthquake. Our results indicate that the earthquake had no statistically significant effect on first-year enrolment at the University of L’Aquila in the three academic years after the disaster. This natural disaster, however, caused a compositional change in the first-year student population, with a substantial increase in the number of students aged 21 or above. This is likely to have been driven by post-disaster measures adopted in order to mitigate the expected negative effects on enrolment triggered by the earthquake.     

闲暇如何影响经济增长?——幸福感与经济效率关系的理论研究与仿真模拟

文章以闲暇促进效用(幸福感)的提升为线索,以闲暇对经济效率的积极作用为基础,构建内生增长模型展开分析。结果显示,长期增长率由闲暇的跨期替代弹性和边际效率增长率决定。前者表征闲暇对生产是替代的还是互补的,后者代表闲暇对效率的动态作用。文章还对此结论做了数值仿真,结果显示,当闲暇对效率的作用为负时,如果其他条件不变,经济最终收敛或出现衰退。文章最后在对不同情形下闲暇对内生增长的作用进行总结和分析的基础上,提出努力推动国民的闲暇活动具有积极健康的内涵,有利于提高经济效率和幸福感,进而促进经济的持续增长。     

城市居民休闲时间投入意愿及其影响因素研究——以杭州市为例

调查了杭州市居民休闲时间的投入意愿,结合杭州市的社会文化背景,分析影响居民休闲时间投入意愿的因素。研究发现,年龄、性别、职业和文化程度是影响居民休闲时间投入意愿的重要因素。总体上,年龄越小,文化程度越高,休闲时间投入意愿越强烈;性别对休闲时间投入意愿的影响主要源自于不同性别在工作生活中的不同角色定位及其休闲偏好。婚姻状况对休闲时间投入意愿影响不大,收入对此没有影响。对于不同的休闲活动项目,影响居民休闲时间投入意愿的变量各不相同,由此得出诸多居民休闲意愿特征。     

Non-neutral responses to money supply shocks when consumption and leisure are Pareto substitutes

Summary. To a greater extent than is often stressed in existing literature, preference assumptions affect responses to money shocks in equilibrium monetary models. Temporary money shocks can have persistent real effects if the marginal utility of leisure is a decreasing function of consumption, where leisure is measured as time endowment less market labor effort, and consumption refers to market produced goods. This condition is an empirically supported implication of home production models. Though not theoretically necessary for supporting the existence of short run real effects, the presence of distortionary taxes and endogenous productivity can have significant quantitative effects on responses to temporary money supply shocks.

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.     

Sugar daddy u: human capital investment and the university-based supply of ‘romantic arrangements’

To deal with the financial hardships associated with rising college tuition, many female college students in the U.S. are turning to risqué forms of financing human capital investments, such as agreeing to potentially lucrative ‘romantic arrangements’ with older males, referred to as ‘sugar daddies,’ through the largest Internet-based club in the industry. Yet despite this recent trend, there is a relative paucity of published academic research on the economics of such behaviour. Using data from the more than 220 nationally ranked (by U.S. News & World Report’s America’s Best Colleges) colleges and universities in the U.S., presents results from both Poisson and scaled Poisson estimation suggesting that large, high-cost universities that are located in larger cities or where unemployment rates are higher lead the nation in the number of female students choosing such romantic arrangements in order to fund higher education. Moreover, those institutions that are chosen by more physically attractive female students, and those that enrol a higher percentage of female students, are also generating greater numbers of female student entrants into the sugar daddy industry. Each of these findings has implications for the human capital literature and the growing body of academic literature on the economics of beauty.     

Dynamics of female labour force participation in France

This article formulates and estimates a structural intertemporal model of labour force participation. Relying on theoretical characterizations derived from an economic model of lifetime behaviour, we estimate a dynamic probit model with correlated random effects using longitudinal data to allow for a dynamic structure. The model is applied to a panel of married women drawn from the 1997–2002 French Labour Force surveys in order to represent their participation behaviour. It is estimated by maximum simulated likelihood. Our results show that women’s decisions to go out to work are characterized by significant state dependence, unobserved heterogeneity and negative serial correlation in the transitory error component. In addition, we find that the presence of young children in a woman’s household reduces her labour participation, but unequally according to their age and number. As expected, educational level has a positive impact on women’s participation. Last, a rise in the husband’s wage is found to raise female participation initially and to lower it subsequently. This empirical finding suggests that leisure may not systematically be a normal good, contrary to what is frequently assumed in the literature.     

On the optimality of escalating penalties for repeat offences against the academic honour code

Although academic dishonesty has a long history in academia, its pervasiveness has recently reached an alarming level. Academic dishonesty not only undermines the purpose of education and the assessment process but also threatens the creditability of academic records. We propose a framework for analysing students’ behaviour with respect to academic policies and honour codes. We draw an analogy between law enforcement and academic integrity enforcement and highlight similarities and differences. The proposed framework captures major determinants of academic dishonesty reported in the literature, namely detection probability, punishment severity, class average and record of academic deviance. The framework models both students’ development of nonacademic skills to improve their grades and teaching assistants’ development of detection skills, which both affect the detection probability. Our analysis demonstrates that the optimality of escalating penalties is conditional on the offenders and academic policy enforcers learning. Use-case scenarios are presented to facilitate the implementation of our results in classrooms.

Ugo Broggi: a precursor in mathematical economics

The concern for the existence of solution to the Walras - Cassel model is usually dated at the beginning of the 1930s, and one decade later the proof of existence of utility function. Ugo Broggi, however, posed both issues in 1923 and 1919, respectively, and even hinted at modern ways of solving them. He was an outstanding mathematician, a former disciple of David Hilbert and collaborator with the Giornale degli Economisti. Broggi's achievements are also linked to a critical reading of Osorio's treatise on Paretian economics.
