Technical Progress and the Natural Rate in Models of the UK Economy

Abstract

This article analyses the role of technical progress in three models of the UK economy. In the standard neoclassical growth model, the growth of the economy is dictated by the growth rate of technical progress plus that of the population. Our two simulation experiments, increasing the level of technical progress by 1 per cent and the growth rate by 0.1 percentage points, suggest that technological progress plays the same role in these large macroeconometric models. In both cases the result is higher output and real wages. However adjustment following the shocks is protracted, giving substantial technological unemployment which in several instances is permanent.
