This thesis analyzes the impact of participation in the Erasmus international mobility program on the academic and job market outcomes of students at the Politecnico di Milano, using administrative data and student survey. The objective is to assess the extent to which studying abroad influences university performance and the early stages of entry into the labor market. The analysis adopts two complementary approaches: a Propensity Score Matching (PSM) model to estimate the effects throughout the entire course of study and a Conditional Difference-in-Differences (CDiD) model to measure the short-term impacts during the year of mobility. The results show positive and statistically significant effects of participation in the Erasmus program, particularly for students enrolled in master’s degrees in Engineering. Higher graduation grades, shorter completion times, and a greater like- lihood of graduating with honors are observed. In terms of employment, mobility is associated with greater job opportunities abroad and higher starting salaries compared to non-participants. The heterogeneity analysis also shows that the positive effects are more pronounced for students with medium-high ISEE (Equivalent Economic Situation Indicator), for those who leave after the first year of the course, for those with academic abilities below the median, and for those who choose destinations in Northern or Southern Europe. In summary, the Erasmus experience emerges as a factor in educational and professional growth, capable of improving university results and facilitating entry into the world of work.
Questa tesi analizza l’impatto della partecipazione al programma di mobilità internazionale Erasmus sui risultati accademici e sugli esiti occupazionali degli studenti del Politecnico di Milano, utilizzando dati amministrativi e questionari studenteschi. L’obiettivo è valutare in che misura l’esperienza di studio all’estero influenzi il rendimento universitario e le prime fasi di inserimento nel mercato del lavoro. L’analisi adotta due approcci complementari: un modello di Propensity Score Matching (PSM) per stimare gli effetti lungo l’intero percorso di studi e un Conditional Difference-in- Differences (CDiD) per misurare gli impatti nel breve periodo, durante l’anno di mobilità. I risultati evidenziano effetti positivi e statisticamente significativi della partecipazione al programma Erasmus, in particolare per gli studenti delle lauree magistrali in Ingegneria. Si osservano un voto di laurea più elevato, tempi di completamento più brevi e una maggiore probabilità di conseguire la lode. Sul piano occupazionale, la mobilità si associa a maggiori opportunità di lavoro all’estero e a retribuzioni iniziali superiori rispetto ai non partecipanti. L’analisi di eterogeneità mostra inoltre che gli effetti positivi sono più marcati per gli studenti con ISEE medio-alto, per chi parte dopo il primo anno di corso, per chi presenta abilità accademiche inferiori alla mediana e per chi sceglie destinazioni nell’Europa del Nord o del Sud. In sintesi, l’esperienza Erasmus emerge come un fattore di crescita formativa e professionale, capace di migliorare i risultati universitari e facilitare l’ingresso nel mondo del lavoro.

Abstract
This thesis analyzes the impact of participation in the Erasmus international mobility program on the academic and job market outcomes of students at the Politecnico di Milano, using administrative data and student survey. The objective is to assess the extent to which studying abroad influences university performance and the early stages of entry into the labor market. The analysis adopts two complementary approaches: a Propensity Score Matching (PSM) model to estimate the effects throughout the entire course of study and a Conditional Difference-in-Differences (CDiD) model to measure the short-term impacts during the year of mobility. The results show positive and statistically significant effects of participation in the Erasmus program, particularly for students enrolled in master’s degrees in Engineering. Higher graduation grades, shorter completion times, and a greater like- lihood of graduating with honors are observed. In terms of employment, mobility is associated with greater job opportunities abroad and higher starting salaries compared to non-participants. The heterogeneity analysis also shows that the positive effects are more pronounced for students with medium-high ISEE (Equivalent Economic Situation Indicator), for those who leave after the first year of the course, for those with academic abilities below the median, and for those who choose destinations in Northern or Southern Europe. In summary, the Erasmus experience emerges as a factor in educational and professional growth, capable of improving university results and facilitating entry into the world of work.| File | Dimensione | Formato | |
