We explain the proliferation of panel data studies in terms of (i) data availability, (ii) the more heightened capacity for modeling the complexity of human behavior than a single cross-section or time series data can possibly allow, and (iii) challenging methodology. Advantages and issues of panel data modeling are also discussed.

Panel data analysis—advantages and challenges

: One use of spectral analysis of time series is to determine if two different time series are realizations from the same process This thesis develops the theory behind Krishnaiah and Schuurmann's theoretical work reported in their report Approximations to the Distributions of the Traces of Complex Multivariate Beta and F Matrices We take the trace of a test statistic calculated from the spectral density matrices of the time series and test it The thesis applies the theory to two small sample simulations (Author)

Spectral Analysis of Time Series.

Será que a desigualdade de rendimentos aumentou durante os últimos tempos? Quem ganhou e quem perdeu neste processo? Este processo afectou todos os países da OCDE uniformemente? Em que medida é que maiores desigualdades de rendimentos são a consequência de maiores diferenças nos rendimentos dos trabalhadores e até que ponto são afectados por outros factores? Finalmente, como é que a redistribuição governamental através do sistema de benefícios fiscais afecta estas tendências?

Book Review: OECD, Growing Unequal? Income Distribution and Poverty in OECD Countries:

In their widely cited study, Shavit and Blossfeld report stability of socioeconomic inequalities in educational attainment over much of the 20th century in 11 out of 13 countries. This article outlines reasons why one might expect to find declining class inequalities in educational attainment, and, using a large data set, the authors analyze educational inequality among cohorts born in the first two-thirds of the 20th century in eight European countries. They find, as expected, a widespread decline in educational inequality between students coming from different social origins. Their results are robust to other possible choices of method and variables, and the authors offer some explanations of why their findings contradict Shavit and Blossfeld's conclusions.

Nonpersistent inequality in educational attainment: evidence from eight European countries.

Fairness in education: The Italian university before and after the reform

This paper proposes a definition of equality of educational opportunities. Then, it develops a comprehensive model that allows to test for the existence of equality of opportunity in a given distribution and to rank distributions according to equality of opportunity. Finally, it provides an empirical analysis of equality of opportunity for higher education in Italy.

Higher education and equality of opportunity in Italy

This paper studies the cross-country differences in conventional measures of inequality of opportunity in Europe in the space of individual disposable incomes. Exploiting two recent waves of the EUSILC database reporting information on family background (2005 and 2011), we provide estimates of inequality of opportunity in about 30 European countries for two sufficiently distant data points, allowing a check of consistency for country rankings. In addition, we exploit two observations available for most of the countries to explore the relationship between many institutional dimensions and inequality of opportunity, finding evidence of negative correlation with educational expenditure (especially at the pre-primary level) and passive labour market policies.

Inequality of Opportunity in Europe: Is There a Role for Institutions?☆

In this paper we show that highly skilled clandestine migrants are more likely to return home than migrants with low or no skills when illegality causes “skill waste”, i.e. when illegality reduces the rate of return of individual capabilities (i.e. skills and human capital) in the country of destination. In a simple life-cycle framework, illegality is modeled as a tax on skills that reduces the opportunity cost of returning home particularly for the highly skilled. This proposition is tested on a sample of apprehended immigrants that unlawfully crossed the Italian borders in 2003. The estimation confirms that the intention to return to the home country is more likely for highly skilled illegal immigrants. The empirical results of this paper attenuate the common wisdom on the return decisions of legal migrants, according to which low-skill individuals are more likely to go back home (mainly because of negative selfselection).

Intentions to Return of Clandestine Migrants: The Perverse Effect of Illegality on Skills

We employ a two-step approach in investigating the dynamic transmission chan- nels under which globalization factors foster technical efficiency by combining a dynamic efficiency analysis in the stochastic frontier framework, and a time series approach based on VAR and spectral analysis. Using the dataset of the 18 EU countries over 1970-2004, we find that both import and FDI are significant factors in spreading efficiency externalities and thus accelerating technology catch-up in the EU. In particular, the impacts of the import are more prominent in the short-run while those of FDI play a more important role over the longer-run. Furthermore, the impacts of the import are pro-cyclical only in the short-run whereas those of FDI are pro-cyclical mostly over the medium- to the long-run. This evidence is broadly consistent with the sample observation that the recent slowdown of the EU productivity has been closely related to the corresponding FDI decline espe- cially after 2000. Hence, any protection-oriented policy will be likely to be more detrimental for the EU.
