Logistic regressions are commonly used to assess for fair lending across groups of loan applicants. This paper considers estimation of the disparate treatment parameter when the sample is stratified jointly by loan outcome and race covariate. We use Monte Carlo analysis to investigate the...

This paper duscusses tha author's wok on measuring and modelling the New Zealand underground economy, 1968-1994. Particular attention is paid to the relationship between this activity and taxation policy. An optimal level for the effective tax rate is reported, in terms of maximizing the impact...

Using data from the Failed State Task Force data set, this paper argues entering onto positive growth paths for income and infrastructure per capita depend upon a nation’s political stability and its geography. A nation’s achieving sustained long-run growth in both variables is essential to...

We derive saddlepoint approximations for the density and distribution functions of the half-life estimated by OLS from an AR(1) or AR(p) model. Our analytic results are used to prove that none of the integer-order moments of these half-life estimators exist. This provides an explanation for the...

In this paper we investigate the forecasting performance of the non-linear time series SETAR model by using Canadian GDP data from 1965 to 2000. Besides the with-in-sample fit, the forecasting performance of a standard linear ARIMA model for the same sample has also been generated for...

Birth order effects are found in empirical work, but lack theoretical foundations. Our new approach to modelling children provides this. Each child has the same genetic make-up and parents do not favour a child based on its birth order. Each child’s needs change as it grows, and births are...

In this paper we outline the results of some extensive econometric modelling that has been undertaken to establish a time-series of the size of the New Zealand Hidden Economy from 1968 to 1994. The derivation of these data has facilitated a good deal of associated research, and here we draw on...

The USDA Graduate School was founded in 1921 to provide statistical and economic training to the employees of the Department of Agriculture. The School did not grant degrees, but its graduate courses were accepted for credit by a significant number of universities.After its founding, the...

This study uses a multiagent system to investigate English auctions with two-dimensional value signals and agents that learn a signal-averaging factor. I find that signal averaging increases nonlinearly as the common value percent increases, decreases with the number of bidders, and decreases at...

We examine the allocation of spending by divorced parents on both private goods and goods which they share with their child. Sole and joint custody arrangements differ in the pattern of shared goods. Parents play a non-cooperative game. We compute the putcomes under sole and joint custody, and...
