Recently Griffith et al. (2010) updated an existing equilibrium displacement model (EDM) of the Australian pig industry which was then used by Slattery et al. (2010) to estimate the potential industry impacts from an increase in demand for low cholesterol pork (see Bellhouse et al. 2010). In that model the specified market parameters were chosen on the basis of economic theory, previous studies and some assumptions made by the authors. While it was concluded those values adequately represented the price responsiveness of market participants within the industry, uncertainty still exists about their true values. This may have implications for the results generated from the model. In this paper stochastic sensitivity analysis is undertaken to account for that uncertainty. Overall, the EDM results are found to be relatively robust. However, the methodology used allows for the calculation of probabilities to determine the chances of a result contrary to that obtained using the original point estimates.
