How wide is the gap? An investigation of gender wage differences using quantile regression

In this paper we examine the determinants of wages and decompose the observed differences across genders into the "explained by different characteristics" and "explained by different returns components" using a sample of Spanish workers. Apart from the conditional expectation of wages, we estimate the conditional quantile functions for men and women and find that both the absolute wage gap and the part attributed to different returns at each of the quantiles, far from being well represented by their counterparts at the mean, are greater as we move up in the wage range.Gender wage gap, quantile regression, education

Isoscaling and the high Temperature limit

This study shows that isoscaling, usually studied in nuclear reactions, is a phenomenon common to all cases of fair sampling. Exact expressions for the yield ratio $R_{21}$ and approximate expressions for the isoscaling parameters $\alpha$ and $\beta$ are obtained and compared to experimental results. It is concluded that nuclear isoscaling is bound to contain a component due to sampling and, thus, a words of caution is issued to those interested in extracting information about the nuclear equation of state from isoscaling.Comment: 7 pages, 1 figur
