Technical change and total factor productivity growth for Swedish manufacturing and service industries

This article presents alternative specifications of the production functions of a large panel of Swedish firms for the period 1992 to 2000. The period can be characterized as a transition when long-run productivity growth in the Swedish economy improved from being among the weakest to one of the strongest within the Organization for Economic Co-operation and Development (OECD). In order to present a detailed exploration of this dramatic change, the time trend and general index models are applied to estimate Total Factor Productivity (TFP) growth, rate of technical change and returns to scale. The models are extended to allow for firm specific as well as time-varying technical change. The parametric TFP measures are also compared with the nonparametric Solow residual, and several hypotheses are tested to explain the growth patterns in the Swedish economy. It is found that the improved growth rate, initially starting in large exporting manufacturing firms, after a deep economic crisis at the beginning of the 1990s, spilled over to the rest of the economy, both manufacturing and services.
