To what extent have investments in "high-tech" office and information technology capital "delivered" in terms of reducing costs and facilitating productivity growth? In this paper we report results of an exploratory effort examining relationships between investments in high-tech office and information technology capital (OF) and alternative industry performance measures such as labor and multifactor productivity, gross returns to capital, real ex post internal rates of return, and markups over variable costs.Our data is at the two-digit manufacturing level of detail, annual from 1968 through 1986. The capital data on high-tech investment and capital is taken from the capital stock study published by the US Bureau of Economic Analysis, which in turn is based on BEA capital flow tables, input-output tables, and data from the Census and Annual Survey of Manufactures. The hightech OF capital data is a Divisia quantity index comprising office, computing and accounting machinery, communications equipment, scientific and engineering instruments, and photocopy and related equipment.Our principal findings are as follows. We find only very limited evidence indicating a positive correlation between industry profitability and OF/K, the share of OF capital in the total physical capital stock. However, when we employ industry-specific output deflators, results change considerably. For example, in terms of multifactor productivity (MFP) growth, we find that increases in OF/K are negatively correlated with growth in MFP; furthermore, rather than being aggregate labor-saving, increases in OF/K tend to be labor-using.
