One form of data reduction is cluster analysis which is used to separate detailed data into consistuent groups. In this paper we illustrate a useful application of cluster analysis to the data reduction of detailed discrete responses of a type that are often found in large surveys.

This study examines differences in average weekly earnings between public-sector and private-sector employees in Australia. In the 1990s, average weekly earnings of full-time public sector employees were higher than for full-time private sector employees by 10 to 15 percent for males and 20 to...

One form of data reduction is cluster analysis which is used to separate detailed data into constituent groups. This paper illustrates a useful application of cluster analysis to the data reduction of detailed discrete responses of a type that are often found in large surveys. This method is...

Over the last few decades there have been significant increases in student enrolments in Australian non-government schools. It has been suggested that this growth has been the outcome of government subsidies to non-government schools. Despite this significant funding school fees have also been...

In this paper we demonstrate the construction of inverse test confidence intervals for the turning points in estimated nonlinear relationships by the use of the marginal or first derivative function. First, we outline the inverse test confidence interval approach. Then we examine the...

Elasticities are often estimated from the results of demand analysis however, drawing inferences from them may involve assumptions that could influence the outcome. In this paper we investigate one of the most common forms of elasticity which is defined as a ratio of estimated relationships and...

Regression specifications in applied econometrics frequently employ regressors, which are defined as the product of two other regressors to form an interaction. Unfortunately, the interpretation of the results of these models is not as straight forward as in the linear case. In this article, we...

Regression specifications frequently employ regressors that are defined as the product of two other regressors to form an interaction. Unfortunately, these models have a number of potential difficulties when it comes to interpretation. In this paper, we discuss two common aspects of these...

We study the relationship between group size and the extent of risk sharing in an insurance game played over a number of periods with random idiosyncratic and aggregate shocks to income in each period. Risk sharing is attained via agents that receive a high endowment in one period making...
