The problem of classifying a categorical response Y is considered in a nonparametric framework. The distribution of Y depends on a vector of predictors X, where the coordinates Xj of X may be continuous, discrete, or categorical. An algorithm is constructed to select the variables to be used for...

Suppose that X is a random vector with probability distribution P and suppose that denotes a proposed model that involves interesting parameters and relationship between variables. We consider statistical inference procedures for the case where constructed as follows: let [theta](P) denote the...

In this paper, we introduce a new family of rank-dependent measures of inequality and social welfare consistent with the equality of opportunity (EOp) principle. The proposed framework can be used to measure long-term as well as short-term EOp, depending on whether we let permanent income or...

<Para ID="Par1">To gauge inequality in living standards, the distribution of lifetime income is likely to be more relevant than the distribution of current income. Yet, empirical studies of income inequality are typically based on observations of income for one or a few years. In this paper, we exploit a unique...</para>

A crucial issue in efficiency-equality evaluations of tax reforms resides in the possibility that the level as well as the distribution of welfare may change, where the household-specific measures of welfare capture the value of income as well as the value of leisure. A better-designed...
