Differential item functioning (DIF) can lead to an unfair advantage or disadvantage for certain subgroups in educational and psychological testing. Therefore, a variety of statistical methods has been suggested for detecting DIF in the Rasch model. Most of these methods are designed for the...

We investigate the role of fatigue in soccer (football). Although this issue is important for the "productivity" of players and the optimal organization of national and international championships, empirical evidence is lacking. We use data on all the matches played by national teams in all the...

The transition process in Central and Eastern Europe was associated with growing environmental awareness. This paper analyses the determinants of Pollution Abatement and Control Expenditure (PACE) at plant level in the case of Romania using survey data and a Multilevel Regression Model (MRM)....

This paper explores the connection between education and wage inequality in nine European countries. We exploit the quantile regression technique to calculate returns to lower secondary, upper secondary and tertiary education at different points of the wage distribution. We find that returns to...

We use a quantile regression framework to investigate the degree to which work-related training affects the location, scale and shape of the conditional wage distribution. Human capital theory suggests that the percentage returns to training investments will be the same across the conditional...

This paper assesses the potential of "workplace training" with reference to German Apprenticeship. When occupational matching is important, we derive conditions under which firms provide "optimal" training packages. Since the German system broadly meets these conditions, we evaluate the...

Risk averse investors have to be compensated in higher expected returns when facing investments with higher risk. Education is an important investment therefore we use the results for 16 countries to test the positive relationship between return to education and the risk involved in this...

We address the impact of education upon wage inequality by drawing on evidence from fifteen European countries, during a period ranging between 1980 and 1995. We focus on within-educational-levels wage inequality by estimating quantile regressions of Mincer equations and analysing the...

The ANPEC exam has been an important instrument for the Brazilian academic economics since the 1970s. Nowadays, practically all graduate program in economics uses it as selection mechanism. This research has tabulated its microdata to produce a picture of what these numbers can reveal about...
