    A dynamic panel analysis of the profitability of Australian tax entities
    Feeny, S. ; Harris, M. N. ; Loundes, J. ( 2000-11)
    This paper investigates the determinants of profitability of Australian tax entities over the period 1993/94 to 1996/97 for each of 91 three-digit ANZSIC industries. The theoretical model is based on that of Cowling and Waterson (1976). However, it is augmented by the inclusion of lagged profitability to allow for habit persistence in entity profitability. The so-called operational Wansbeek-Bekker estimator is used to control for endogeneity of this lagged dependent variable, whilst simultaneously controlling for observed and unobserved entity heterogeneity. Aggregate results suggest that profitability in the previous year, entity capital intensity, and barriers to entry have the expected positive association with current profitability measured by the price-cost margin. Entity market share-and to a lesser extent concentration-are found to have a U shaped relationship with profitability.

    Habit Persistence in Effective Tax Rates: Evidence Using Australian Tax Entities
    Harris, Mark N. ; Feeny, Simon ( 2000-09)
    This paper uses administrative data from the Australian Tax Office, to model the effective tax rates (ETRs) of large Australian corporates. The extent to which there is any habit persistence in ETRs is also examined. The results suggest that unobserved entity heterogeneity is important in explaining ETRs. In terms of observed heterogeneity, entity size, level of leverage, capital intensity, foreign income and R&D, are all important explanators of ETRs. There is also evidence of a significant amount of habit persistence, implying that ETRs converge monotonically towards the statutory rate of corporation tax.
