| Abstract: | When variables are correlated in time-series studies, it is often difficult to determine which is cause and effect, and in what sense. This paper applies multivariate time-series tests of causality to Australian wage, price, minimum wage award, labour demand and strike (working days lost) variables for 1953-76. The results provide tentative support for a model in which strikes are exogenous:the size of Arbitration Commission awards is determined by strikes (suggesting that a trade union capture theory of Arbitration Commission regulation may apply):money wages are determined by minimum wage awards; and the demand for labour variable (measured in this paper by the ratio of actual to potential output) is determined (in a negative relationship) by money wages. |
