We study the dispersion of wages of full-year workers over two decades controlling for both education and experience. Applying non-parametric statistical methods we find statistically significant and large increases in inequality for males with low levels of education and experience coexist with...

We present a measure of the correlation between the education levels of spouses based on a bivariate ordered probit model. The change in this correlation over time can be measured while controlling for the large changes in the educational attainment levels. The model is estimated with data from...

We study women aged 51-75 who live alone and are not married over the period 1969-1993 using national samples from The Survey of Consumer Finances (SCF) and The Family Expenditure Survey (FAMEX). We examine Income and Expenditure Patterns over the period and find that: there have been...

A Taylor series approach is used to derive approximations to the approximate slope of LR, W, and LM test statistics. These can be useful when the approximate slopes themselves are complicated. The results are applied to the test of linear coefficient restrictions in the linear model with a...

The O(n-1) bias and O(n-2) MSE of OLS are derived for iid samples. An approach is suggested for handling nonexistent finite sample moments. Bias corrections based on plug-in, weighting, jackknife and pairs bootstrap methods are equal to Op(n-3/2). Sometimes they are effective at lowering bias...

We use Canadian Surveys of Consumer Finances 1971-1993 to study the wages of full-time, full-year male and female workers. Median real wages of 24-year-old males without a university degree fell by 25% between 1978 and 1993. For 24-year-old females the decline was more modest and reversed in...

We propose a family of transformations which, unlike the Box-Cox transformation, can sensibly be applied to variables of either sign which may be near or far from zero. We derive two forms of Lagrange multiplier test for the null hypothesis that the dependent variable has not been transformed...
