Using quantile regressions and cross-sectional data from 152 countries, we examine the relationship between inflation and its variability. We consider two measures of inflation -- the mean and median -- and three different measures of inflation variability -- the standard deviation, relative...

The paper attempts to measure income inequality and its changes over the period 1993-2000 for a set of 13 Countries in ECHP. Focusing on wages and incomes of workers in general, inequality is mainly analyzed with respect to educational levels as proxy of individual abilities. Estimation of...

Suppose that a target function f0 : Rd ! R is monotonic, namely, weakly increasing, and an original estimate ^ f of the target function is available, which is not weakly increasing. Many common estimation methods used in statistics produce such estimates ^ f. We show that these estimates can...

The most common approach to estimating conditional quantile curves is to fit a curve, typically linear, pointwise for each quantile. Linear functional forms, coupled with pointwise fitting, are used for a number of reasons including parsimony of the resulting approximations and good...
