Sectoral Solow Residuals

This paper presents capital utilization corrected measures of technology shocks for aggregate and disaggregated (two digit Standard Industrial Classification code) industries. We correct for variations in capital utilization by employing industrial electrical use as a measure of capital services. In contrast, the standard measures of technology shocks used in the Real Business Cycle literature are based on economy wide data and assume that capital services are proportional to the stock of measured capital. To assess the impact of these differences, we contrast selected properties of the competing technology shock measures. We argue that the properties of technology shocks for the manufacturing sector are quite different than those used in the RBC literature. We also find that correcting for capital utilization has important implications for the properties of the Solow residual
