    Discrete hours labour supply modelling: Specification, estimation and simulation
    CREEDY, J ; KALB, GR (John Wiley & Sons, 2005)
    The assumption behind discrete hours labour supply modelling is that utility-maximising individuals choose from a relatively small number of hours levels, rather than being able to vary hours worked continuously. Such models are becoming widely used in view of their substantial advantages, compared with a continuous hours approach, when estimating and their role in tax policy microsimulation. This paper provides an introduction to the basic analytics of discrete hours labour supply modelling. Special attention is given to model specification, maximum likelihood estimation and microsimulation of tax reforms. The analysis is at each stage illustrated by the use of numerical examples. At the end, an empirical example of a hypothetical policy change to the social security system is given to illustrate the role of discrete hours microsimulation in the analysis of tax and transfer policy changes.

    Phillips Curve and the Equilibrium Unemployment Rate*
    LIM, GC ; DIXON, R ; TSIAPLIAS, S (Wiley, 2009-12)
    A time‐varying Phillips Curve was estimated as a means to examine the changing nature of the relationship between wage inflation and the unemployment rate in Australia. The implied time‐varying equilibrium unemployment rate was generated and the analysis showed the important role played by variations in the slope of the Phillips Curve in changing the equilibrium unemployment rate. The deviations of actual unemployment rates from the estimated equilibrium unemployment rates also performed remarkably well as measures of inflationary pressure.

    The role of portfolio shocks in a structural vector autoregressive model of the Australian economy
    Fry, R ; Hocking, J ; Martin, VL (BLACKWELL PUBLISHING, 2008-03)
    Domestic and foreign equity shocks on the Australian economy are analysed within a five‐variate structural vector autoregressive model, with identification achieved through long‐run restrictions based on the natural rate hypothesis, monetary neutrality, long‐run portfolio balance and purchasing power parity. The results show that real equity values were undervalued by 19 per cent by June 2005, with the gap narrowing thereafter. Foreign crises are important factors explaining this deterioration. The real wealth effects of equity market shocks impact significantly upon financial and goods market prices, whereas output tends to be immune. The model is also able to address puzzles that exist in the vector autoregression literature.

    Overcoming measurement error problems in the use of survey data on expectations
    Lee, K ; Shields, K (BLACKWELL PUBLISHING, 2007-09)
    Survey data frequently requires conversion from qualitative responses to quantitative series and it is often asserted that the conversion procedures introduce measurement errors that render the series unusable in structural modelling. We investigate the nature and treatment of the measurement error that arises when conversion procedures are used to obtain direct measures of expectations. We use simulation experiments to demonstrate the need for the adequate treatment of conversion errors and show that a procedure proposed to ‘purge’ the series of conversion error is extremely successful in circumventing the problems. We illustrate the procedures in empirical applications using business survey data.

    Ex post bidding and efficient coordination unemployment
    Julien, B ; Kennes, J ; King, I (WILEY, 2005-02)
    Abstract.  We study the implementation of constrained‐efficient allocations in labour markets where a basic coordination problem leads to an equilibrium matching friction. We argue that these allocations can be achieved in a non‐cooperative equilibrium if wages are determined by ex post bidding. This holds true even in finite‐sized markets where the equilibrium‐matching process has decreasing returns to scale – where the ‘Hosios rule’ does not apply – both with and without heterogeneity.
