1. Page xxi, " Yanquin Fan " ought to be " Yanqin Fan " 2. Page 9, Equation (1.10) (iii), " = κ 2 > 0 " ought to be " = κ 2 < ∞ " Also, in Theorem 1.1, we need to add the conditions that sup ξ∈S(X) |f (l) (ξ)| < ∞, for l = 0, 1, 2, 3, where S(X) denotes the support of X, and that ∫ |v 3 k(v)|dv < ∞.

We propose a partially adaptive estimator based on information theoretic maximum entropy estimates of the error distribution. The maximum entropy (maxent) densities have simple yet flexible functional forms to nest most of the mathematical distributions. Unlike the nonparametric fully adaptive estimators, our parametric esti-mators do not involve choosing a… (More)

A semi-parametric econometric model is used to study the relationship between malaria cases and climatic factors in 25 African countries. Results show that a marginal change in temperature and precipitation levels would lead to a significant change in the number of malaria cases for most countries by the end of the century. Consistent with the existing… (More)

We use a new method to estimate China's income distributions using publicly available interval summary statistics from China's largest national household survey. We examine rural, urban, and overall income distributions for each year from 1985-2001. By estimating the entire distributions, we can show how the distributions change directly as well as examine… (More)

Marginal tax rates have larger income redistribution and equilibrating welfare effects than do social insurance or direct transfer programs. The Earned Income Tax Credit has smaller but still statistically significant desirable effects. Social insurance programs have little effect except for Supplemental Security Income, which increases equality. The… (More)

Traditional treatments of tax pass through examine the tax incidence, which makes sense when the law of one price holds. However in markets with a price distribution, a tax may have an uneven effect across the price distribution so that the tax incidence varies across the distribution. We illustrate variation in tax incidence using two relatively simple… (More)

We are very grateful to the University of California Institute of Industrial Relations and the Giannini Foundation for financial support.

We develop a GMM estimator for the distribution of a variable where summary statistics are available only for intervals of the random variable. Without individual data, one cannot calculate the weighting matrix for the GMM estimator. Instead, we propose a simulated weighting matrix based on a first-step consistent estimate. When the functional form of the… (More)

This study proposes an information-theoretic deconvolution method to approximate the entire distribution of individual treatment effect. This method uses higher-order information implied by the standard average treatment effect estimator to approximate the underlying distribution of individual treatment effect using the method of maximum entropy density.… (More)
