    An employment equation for Australia: 1966-2001
    DIXON, ROBERT ; Freebairn, John ; Lim, G. C. ( 2004-01)
    We model the relationship between hours of work and employment and argue thatunless actual hours are varying with a change in ‘standard hours’, actual hours shouldnot appear in the long-run component of an equation for employment. If howeverstandard hours are changing then it is desirable that this variable be incorporated intothe employment equation. Our theoretical model yields an expression for the elasticityof employment with respect to standard hours which shows that the elasticity isrelated to the size of the premium for overtime. Using quarterly data for the period1966:3 – 2001:3 we estimate a new employment equation for Australia incorporatingstandard hours of work. We find empirical support for our approach and we providenew estimates of the elasticity of employment with respect to the real wage and GDP.We also find a marked asymmetry in the response of employment to variations in realGDP and real wages in recession periods as against non-recession periods.

    The Cyclical Dynamics and Volatilityof Australian Output and Employment
    DIXON, ROBERT ; SHEPHERD, DAVID ( 2006-07)
    In this paper we examine the volatility of aggregate output and employment in Australia withthe aid of a frequency filtering method (the Butterworth filter) that allows each time series to bedecomposed into trend, cycle and noise components. This analysis is compared with moretraditional methods based simply on the examination of first differences in the logs of the rawdata using cointegration-VAR modelling. We show that the application of univariate AR andbivariate VECM methods to the data results in a detrended series which is dominated by noiserather than cyclical variation and gives break points which are not robust to alternativedecomposition methods. Also, our conclusions challenge accepted wisdom in relation to outputvolatility in Australia which holds that there was a once and for all sustained reduction inoutput volatility in or around 1984. We do not find any convincing evidence for a sustainedreduction in the cyclical volatility of the GDP (or employment) series at that time, but we dofind evidence of a sustained reduction in the cyclical volatility of the GDP (and employment)series in 1993/4. We also find that there is a clear association between output volatility andemployment volatility. We discuss the key features of the business cycle we have identified aswell as some of the policy implications of our results.
