Changes in Technology and Preferences : A General Equilibrium Explanation of Rapid Growth in Trade

We use a computable general equilibrium model in an explanation of the recent rapid growth in Australia's trade, particularly intra-industry trade. Relative to previous studies of trade growth based on multiple regression analysis, our approach allows us to: (i) work at a detailed industry level; (ii) use primary variables to represent changes in technology and preferences rather than proxies; and (iii) use a framework based on explicit microeconomic foundations. We find that most of the growth in Australia's trade relative to GDP is explained by changes in technology and preferences
