The Impact of High-Tech Capital on Productivity: Evidence from Australia

This article examines the relationship between high-tech capital use and productivity. Using Australian data, some evidence is found of a positive relationship between high-tech capital use and productivity in the market sector, but there is much less evidence of excess returns. These results are robust to the use of a variety of different measures of high-tech capital. At the industry level however, the relationship is significant and positive for only some industries. This suggests that the benefits of investment in high-tech capital are not spread evenly across the economy. (JEL O3) Copyright 2006, Oxford University Press.
