Abstract

For the 1990s, the basic neoclassical growth model predicts a depressed economy, when in fact the US economy boomed. We extend the base model by introducing intangible investment and non-neutral technology change with respect to producing intangible investment goods and find that the 1990s are not puzzling in light of this new theory. There is microeconomic and macroeconomic evidence motivating our extension, and the theory's predictions are in conformity with US national accounts and capital gains. We compare accounting measures with corresponding measures for our model economy and find that standard accounting measures greatly understate the 1990s boom. (JEL E22, E23, O33, O47).
