TL;DR: In this article, a generalized Hausman-Taylor estimation method was proposed to estimate the gravity equation of bilateral trade flows among 15 European countries over 1960-2001, and the results showed that the proposed approach provided more sensible results than the conventional approach based on fixed time dummies.

TL;DR: In this article, the authors studied the degree of equality of educational opportunity in the Italian university system and provided testable conditions with the aim of testing for the existence of EOP in a given distribution and ranking distributions on the basis of EOp.

TL;DR: This paper analyzed the extent of income inequality and opportunity inequality in 25 European countries and found that ex-ante equality of opportunity exhibits a positive correlation with public expenditure in education, whereas ex-post inequality of opportunity is also positively associated with union presence and to fiscal redistribution.

TL;DR: In this article, the gravity equation of bilateral trade flows among 15 European countries over 1960-2001 is analyzed. But the authors explicitly allow for the existence of unobserved common time-specific factors where their individual responses are also allowed to be heterogeneous across cross-section units.

TL;DR: In this article, a unified framework for accommodating both time and cross-sectional dependence in modelling technical efficiency in stochastic frontier models by combining the exogenously driven factor-based approach and an endogenous threshold efficiency regime selection mechanism was proposed.
