Opis:: Research on performance in mathematics shows that an average achievement of men and women is only slightly different. A much bigger difference exists among students at high achievement levels; in this group, there are more boys than girls. This paper addresses the question how mathematical subdisciplines and types of tests shape gender proportion at higher percentiles of achievement distribution. An analysis of a wide range of data including the results of PISA, exams taken at the end of lower secondary school and high school as well as so-called “mathematical Olympics” brings out three conclusions: (1) there is a gender gap in all subscales of PISA scales, (2) the largest differences exist in scales related to spatial abilities, (3) gender gap widens together with an increase in the level of difficulty as well as with the transition to higher educational levels.

Tytuł:: Robust Estimation in VaR Modelling - Univariate Approaches using Bounded Innovation Propagation and Regression Quantiles Methodology

ARMA-GARCH models
Opis:: In the paper we present robust estimation methods based on bounded innovation propagation filters and quantile regression, applied to measure Value at Risk. To illustrate advantage connected with the robust methods, we compare VaR forecasts of several group of instruments in the period of high uncertainty on the financial markets with the ones modelled using traditional quasi-likelihood estimation. For comparative purpose we use three groups of tests i.e. based on Bernoulli trial models, on decision making aspect, and on the expected shortfall.

Tytuł:: Returns to Education and Gender Wage Gap Across Quantiles in Italy
Autorzy:: Furno, Marilena
Powiązania:: https://bibliotekanauki.pl/articles/2075508.pdf
Data publikacji:: 2020
Wydawca:: Polska Akademia Nauk. Czytelnia Czasopism PAN
Tematy:: quantile regression
decomposition
returns to education
gender wage gap
Opis:: Various quantile regression approaches are implemented to analyze the characteristics of Italian data on earnings in the tails. A changing coefficients pattern across quantiles shows increasing returns to education along the wage distribution. A quantile decomposition approach shows that higher education grants higher return at all quantiles, thus implying additional, non-linear returns to higher education throughout the entire pattern of the earning distribution. Wage gender gap displays a decreasing pattern across quantiles, and it does not disappear at the higher quantiles. The southern workers penalty decreases across quantiles as well for highly educated workers.
