This paper first derives an adaptive estimator when heteroskedasticity is present in the unit-specific error in an error component model and then compares the finite sample performance of the proposed estimator with various other estimators. While the Monte Carlo results show that the proposed...

That mortgage lenders have complex underwriting standards, often differing legitimately from one lender to another, implies that any statistical model estimated to approximate these standards, for use in fair lending determinations, must be misspecified. Exploration of the sensitivity of...

This paper estimates the relationship between calorie intake and income within a semiparametric framework, which allows for heterogeneity across individuals and possible nonlinearity in the relationship. The results, using a panel data set from rural south India, indicate that the income...

The binary logistic regression or logit link model is commonly used to test for racial disparate treatment in fairlending studies undertaken by government agencies, including the Office of the Comptroller of the Currency (OCC) and the Federal Reserve Board (FRB). Ensuring race neutrality in...

We examine inference for Generalized Entropy and Atkinson inequality measures with complex survey data, using Wald statistics with variance–covariance matrices estimated from a linearization approximation method. Testing the equality of two or more inequality measures, including sub-group...

The world has experienced impressive improvements in wealth and health, with, for instance, the world’s real GDP per capita having increased by 180% from 1970 to 2007 accompanied by a 50% decline in infant mortality rate. Healthier and wealthier. Are health gains arising from wealth growth?...
