The Duration of Industrial Disputes in Australian Mining and Manufacturing

Using a unique dispute‐level database of industrial action in Australian mining and manufacturing industries, this paper investigates the determinants of the duration of industrial action. For the first time in the Australian literature, the duration of individual disputes is analysed within a hazard function framework that estimates conditional settlement probabilities over the duration of the dispute. Further, the analysis is conducted for both strikes and non‐strike forms of industrial action such as bans on working overtime. A range of parametric and semi‐parametric specifications are estimated in order to determine the sensitivity of the results to alternative econometric techniques. The duration of both strikes and work bans are found to be affected by a range of factors, including the state of the labour market, industry characteristics, past union experiences and the cause of the dispute. The conditional settlement rate of both strikes and bans are found to be upward sloping, implying that the longer that a dispute has already lasted, the more likely that it is to end. However, failing to control for unobserved heterogeneity results in bias toward declining conditional settlement rates.
