Average price-cost margins are calculated for 34 Australian manufacturing industries. Multiple regression analysis is employed to determine a relationship between price-cost margins and several variables, including concentration, risk, plant size, industry growth, the nature of the industry's product, and the geographic markets served by the industry. A brief comparison is made between the results for Australia and those found in other countries. Given the data available and the multicollinearity of the variables, it is difficult to see how this study, and the overseas studies, can draw reliable conclusions on the determinants of price-cost margins.
