Equity Prices, Productivity Growth, And ‘The New Economy’
The increase in equity prices over the 1990s has to a large degree been attributed to permanently higher productivity growth that is derived from the ‘new economy’ and related research and development (R&D) expenditures. This paper establishes a rational expectations model of technology innovations and equity prices, which shows that under plausible assumptions,productivity advances can only have temporary effects on fundamentals of equity prices. Using data on R&D capital and fixed capital productivity for 11 OECD countries, the evidence give strong support for the model by suggesting that technology innovations indeed have only temporary effects on equity returns.
