Imperfect Competition, Returns To Scale and Productivity Growth In Australian Manufacturing: A Smooth Transition Approach To Trade Liberalisation

This Paper examines the relationship between trade liberalization and productivity growth for Australian manufacturing. An imperfect competition, non-CRS, smooth transition empirical framework is employed for analysis. GMM estimates of the logistic smooth transition model imply that trade reform impacts take approximately four years to complete, but do not occur over the same time period for all industries. In response to trade reforms, for most industries a significant improvement in productivity is estimated, these improvements are associated with lower mark-ups and falling scale parameters. A minority of industries however, experienced no change or falling productivity growth in response to reforms, these industries tended to have the highest absolute protection levels.
