Absenteeism and Peer Interaction Effects: Evidence from an Italian Public Institute

Using microdata on a sample of about 350 workers, employed at an Italian public institute, we explain individual absence rates both considering variables that may be related to health conditions and to variables that may suggest shirking behaviour. Among these variables we especially focus our attention on the influence produced by the behaviour of randomly assigned peers. To handle reflection problems we use the proportion of females in the peer group as instrument of peer absence behaviour. From Two-Stage least square estimates it emerges that social and group interactions play an important role in shaping individual absence behaviour.Absenteeism, Shirking, Peer Effects

Are easy grading practices induced by low demand? Evidence from Italy

In this paper we investigate whether grades are used by educational institutions as a competition variable to attract and retain students. Using a sample of almost 26,000 students enrolled at an Italian University, we document that grades vary significantly across degrees. After controlling for students’ characteristics, class-size, classmates’ quality and degree fixed effects, it emerges that students obtain better grades and are less likely to drop-out when their degree course experiences an excess of supply. We adopt an instrumental variable strategy to account for endogeneity problems and instrument the excess of supply by using the total number of universities offering each degree course. Our IV estimates confirm that the teaching staff on degree course facing low demand tend to set lower academic standards with the result that their students obtain better grades and have a lower probability of dropping out than they might otherwise.grades, higher education, grading standards

Does Teacher Quality Affect Student Performance? Evidence from an Italian University

In this paper we analyse whether the characteristics of university teaching staff matter with regards students’ performance and interest in the discipline. We use data on about one thousand students enrolled on the first level degree course in Business and Economics at a medium sized Italian University. Thanks to the random assignment of students to different teaching sections during their first year, we are able to analyze the effect that teachers with different characteristics, in terms of experience and research productivity, produce both on students’ performance, measured in terms of the grades obtained at subsequent exams and courses chosen. Our results suggest that teacher quality has statistically significant effects on students’ grades on subsequent courses. These effects are also robust after controlling for unobserved individual characteristics. On the other hand, we find less clear evidence when relating teacher quality to student involvement with a subject. It emerges that more experienced teachers have a negative impact on the probability of a student’s undertaking additional courses in a subject, while research productivity does not produce a statistically significant effect.teaching quality, student performance,

The Effects of Managerial Turnover: Evidence from Coach Dismissals in Italian Soccer Teams

In this paper sport data are used to study the effects of manager replacement on firm performance. Using match results of the major Italian soccer league (“Serie A”) we analyze the effects of coach (manager) changes in terms of team performance. From our preliminary estimates, including year and team fixed effects, it emerges that changing the coach produces a positive effect on a number of measures of team performance. However, this effect turns out to be statistically insignificant once we take into account the fact that the firing of a coach is not an exogenous event, but it is triggered by a “dip” in team performance. Using as an instrument for coach change the number of remaining matches in the season (which is a proxy for the residual length of the coach contract) Two-Stages Least Squares estimations do not show any significant effect of coach change on team performance.Managerial Turnover, Dismissal; Performance evaluation; Sport economics

THE CAUSAL IMPACT OF CLOSENESS ON ELECTORAL PARTICIPATION EXPLOITING THE ITALIAN DUAL BALLOT SYSTEM

Using data from Italian municipal elections from 1993 to 2011, we investigate whether political competition affects electoral turnout. Taking advantage of the dual ballot system adopted for municipalities with more than 15,000 inhabitants, we measure the expected closeness in the second round through the first round electoral results. Thanks to the richness of our dataset we are able to distinguish between valid, blank and invalid ballots and to investigate the effect of closeness on each of these variables, controlling for municipalities’ and candidates’ characteristics and for municipal fixed effects. We also estimate a Heckman selection model to take into account for the non-randomly selected sample. It emerges that closeness strongly increases valid ballots and reduces blank ballots supporting the idea that the expected benefits of voting increase in closer competitions. The effect is much higher in magnitude than that merging when measuring closeness with ex-post electoral results, suggesting a quite relevant endogeneity bias. On the other hand, we do not find any statistically significant effect on invalid ballots.Electoral Turnout, Closeness, Electoral Competition, Blank and Invalid Ballots

MEDIA EXPOSURE AND INDIVIDUAL CHOICES: EVIDENCE FROM LOTTO PLAYERS

To what extent individual choices are influenced by media exposure? We try to provide evidence on this issue considering how the sales of lotto tickets are determined by the size of the top prize (the jackpot) compared to the amount of attention that media devote to the game. We use data on the Italian SuperEnalotto (2003- 2010) and estimate tickets sales in relation to the jackpot size and to several measures of lotto media coverage. To take into account that media attention may be affected by the amount of tickets sold we instrument media coverage with the availability of other newsworthy material (sport events and disasters). It emerges that media attention to the game is inversely related to the availability of other news. Two-Stage-Least Squares Estimations show that, given the jackpot size, players spend more on lotto when media attention to the game is higher.Media Influence, Media Exposure, Psychology and Economics, Lottery, Instrumental Variables

THE EFFECTS OF PEOPLES’ HEIGHT AND RELATIVE HEIGHT ON WELL-BEING

Using a rich Italian survey, we investigate the effect of height on individual happiness. From our analysis it emerges that a large part of the effect of height on well-being is driven by a positive correlation between height and economic and health conditions. However, for young males the effect of height on happiness persists even after controlling for these variables, implying that height may produce some psycho-social direct effects on well-being. Consistent with this hypothesis, we find that males care not only about their own height but also about the height of people in their reference group. Well-being is greater for individuals who are taller than other subjects in their reference group. Results are robust to different definitions of reference group and controlling for a number of other reference group characteristics. We speculate that the beneficial effect of height on young males' well-being may be related to the fact that in some countries, such as Italy, and especially for men, height is considered as a proxy for handsomeness.height, social comparison, subjective well-being

The Role of Family Ties in the Labour Market. An Interpretation Based on Efficiency Wage Theory

By casual empiricism, it seems that many firms take explicit account of the family ties connecting workers, often hiring individuals belonging to the same family or passing jobs on from parents to their children. This paper makes an attempt to explain this behaviour by introducing the assumption of altruism within the family and supposing that agents maximise a family utility function rather than an individual one. This hypothesis has been almost ignored in the analysis of the relationship between employers and employees. The implications of this assumption in the efficiency wage models are explored: by employing members of the same family, firms can use a (credible) harsher threat¬ – involving all the family’s members in case of one member’s shirking - that allows them to pay a lower efficiency wage. On the other hand, workers who accept this agreement exchange a reduction in wage with an increase in their probability of being employed: this can be optimal in situation of high unemployment. Moreover, the link between parents and children allows the firm to follow a strategy that solves the problem of an individual’s finite time horizon through family’s reputation.

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 dataset, 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 assigning 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.Peer effects; Student performance; Educational production function; instrumental variables

Gender Discrimination and Evaluators’ Gender: Evidence from the Italian Academy

Relying on a natural experiment consisting in 130 competitions for promotion to associate and full professor in the Italian University, we analyze whether gender discrimination is affected by the gender of evaluators. Taking advantage of the random assignment of evaluators to each competition, we examine the probability of success of each candidate in relation to the committee gender composition, controlling for candidates’ scientific productivity and a number of individual characteristics. We find that female candidates are less likely to be promoted when the committee is composed exclusively by males, while the gender gap disappears when the candidates are evaluated by a mixed sex committee. Results are qualitatively similar across fields and type of competitions. The analysis of candidates’ decisions to withdraw from competition highlights that gender differences in preferences for competition play only a minor role in explaining gender discrimination. It also emerges that withdrawal decisions are not affected by the committee gender composition and therefore the gender discrimination is not related to self-fulfilling expectations.Gender Discrimination, Evaluators’ Gender, Affirmative Actions, Academic Promotion
