TL;DR: In this paper, the authors proposed a deformation of fairness in education which is based on the theory of equality of opportunity developed in the last decades in the philosophical and economic literature, and derived opportunity inequality measures based on such conceptual framework, and used these measures to evaluate the 1999 reform of the Italian university system (the so called 3+2" reform).
Abstract: In this paper we propose a de_nition of fairness in education which is based onthe theory of equality of opportunity developed in the last decades in the philosophical and economic literature (Roemer,1998; Fleurbaey, 2008), we derive opportunity inequality measures based on such conceptual framework, and we use these measures to evaluate the 1999 reform of the Italian university system (the so called “3+2" reform). Looking at 1995-2004 college graduates data our estimates show an improvement in the equality of opportunity in the access to university. However, the aggregated data available for the 2005-2008 suggest that such a positive e_ect may vanish in the medium run.

TL;DR: In this paper, the authors extend the MSS model by combining panel threshold regression technique advanced by Hansen (1999) to analyze regime-specific stochastic frontiers and complex time-varying patterns of technical efficiencies in a robust manner.
Abstract: Recently, Mastromarco, Serlenga and Shin (2010) propose a two-step approach to examine dynamic transmission mechanism under which globalization factors foster technology efficiency. In this paper, we extend the MSS model by combining panel threshold regression technique advanced by Hansen (1999). This threshold stochastic frontier panel data model enables us to analyze regime-specific stochastic frontiers and complex time-varying patterns of technical efficiencies in a robust manner. Using a dataset of 44 countries over 1970-2007, we find that income elasticities of labour and capital and time-varying common efficiencies are substantially different under superior and inferior frontiers. Capital and labour inputs are more productive under superior frontier. More importantly, common efficiencies have steadily increased under superior frontier, but technical efficiency has monotonically decreased for low income countries, supporting the so-called club convergence hypothesis. Furthermore, the VAR-based impulse response analyses suggest that openness factors through FDI and trade help the countries improve production technology and efficiency position relative to the frontier only after the country has reached a certain level of development.

TL;DR: In this article, the relationship between wage inequality and education in 13 OECD countries over the period 1985-2005 using the Luxembourgh Income Study (LIS) data was studied, showing that the increase in wage inequality in the countries considered can only partially be explained by observable characteristics such as education and educational premia.
Abstract: In this paper we study the relationship between wage inequality and education in 13 OECD countries over the period 1985-2005 using the Luxembourgh Income Study (LIS) data. Our results show a great deal of heterogeneity in the patterns of the rate-of-return estimates across countries. On the other hand, our results confirm the finding of a general increase in wage inequality. As for the correlation between wage premia and wage inequality, the results show a positive but weak correlation between the estimates of the education return and the Gini index and between the convexity of wage premia and wage inequality. The results show that the increase in wage inequality in the countries considered can only partially be accounted for by observable characteristics such as education and educational premia; i.e., it is largely residual in its nature.
