Quantile regression has emerged as an essential statistical tool of contemporary empirical economics and biostatistics. Complementing classical least squares regression methods which are designed to estimate conditional mean models, quantile regression provides an ensemble of techniques for estimating families of conditional quantile models, thus offering a more complete view of the stochastic relationship among variables. This volume collects 12 outstanding empirical contributions in economics and offers an indispensable introduction to interpretation, implementation, and inference aspects...

In the presence of a skill bias in labor demand, which increases the relative de mand for more highly skilled labor over time, there only seems to exist the choice between higher wage inequality or higher unemployment rates.

The analysis ranges from extensive descriptive evidence on wage trends to the estimation of a struc tural...
