Motivation • Sharp increase in the supply of higher education graduates • Number of works document how the average return to higher education has changed in Hungary, but very little is known about the causes of differences in labour market success among graduates • Large differences in earnings and employment probability across fields • Wage dispersion of higher education graduates has increased SEBA – IE CASS - IEHAS Conference Budapest 30.. 06. 2011.

Wage returns to higher education (%) by level of education (college/university) Based on data of Hungarian Wage Tariff Surveys. Dependent variable: (log) earnings; Control variables: educational categories dummies, gender, experience, experience squared. The percentage effect is (eß–1) × 100 % . N (Total ):190-230 thousands; N ( young): 38-40 thousands SEBA – IE CASS - IEHAS Conference Budapest 30.. 06. 2011.
Research question Does the field of study and the institution of graduation affect early labour market success (earnings and employment probabilities) of graduates? SEBA – IE CASS - IEHAS Conference Budapest 30.. 06. 2011.
Data • Survey of Hungarian Higher Education Graduates 2010 • Representative sample of graduates in 2007 • Sample 10 % of the population of graduates (4507 persons) • 10 fields of study, 25 institutions SSEBA – IE CASS - IEHAS Conference Budapest 30.. 06. 2011.

Measurement problems • non-random selection of students into different fields of study and different institutions • more able students are admitted to more selective institutions and fields of study • factors may influence both the choice of field of study and of institution and earnings (abilities) SEBA – IE CASS - IEHAS Conference Budapest 30.. 06. 2011. .
Measurement problems • two methods are used to control for the potential self-selection of graduates • effect of field of study: propensity score matching method, average treatment effect on the treated • effect of institution: HLM-like regressions • with field of study * institution fixed effects SEBA – IE CASS - IEHAS Conference Budapest 30.. 06. 2011. .
Method 1. Effect of the field of study propensity score matching method – average treatment effect on the treated E(Y1|D=1) – E(Y0|D=1) P(X)=Pr(D=1|X)=E(D|X) E[Y1|D=1,P(X)]-E[Y0|D=0,P(X)] D =1 treated: person graduated from the given field of study D=0 control: person graduated from another field of study Y1 – outcome measures (earnings, employment probability) X – observed covariates SEBA – IE CASS - IEHAS Conference Budapest 30.. 06. 2011. .
Method 1. Effect of the field of study Independent variables (observables): Matching methods: nearest neighbor method (ATTND) and stratification method (ATTS) SEBA – IE CASS - IEHAS Conference Budapest 30.. 06. 2011.

Conclusions • some fields of studies have casual effect on early labour market success of graduates • earnings of graduates from business and economics and from law are higher • earnings and employment probabilities of graduates from teacher training are lower • no robust effects of the institutions, with the exception of BGF (higher wages, lower employment probabilities) SEBA – IE CASS - IEHAS Conference Budapest 30.. 06. 2011.
