Output, Input, and Productivity Measurement in U.S. Agriculture, 1948-79

چکیده
Tornqvist-Theil indexes of outputs and inputs are constructed. These data are used to construct indexes of productivity growth over the postwar period. The productivity indexes can be derived from a flexible multioutput-multifactor representation of the structure of production constrained to constant returns to scale. Total factor productivity grew at an average annual rate of 1.75%, compared with 1.70% per year estimated by the U.S. Department of Agriculture. The similar estimates of productivity growth overshadow some important differences in measurement of individual inputs.

Measurement of productivity growth in U.S. manufacturing
The indexes of multifactor productivity for two-digit manufacturing sectors prepared by the Bureau of Labor Statistics for sectors in manufacturing have been revised and extended to cover the 1949–92 period. These indexes, also called the “KLEMS” multifactor measures, compare changes in output to changes in a composite of all the inputs used in production—capital, labor, energy inputs, nonenerg...
متن کاملIntangible Capital and Measured Productivity
Because firms invest heavily in R&D, software, brands, and other intangible assets—at a rate close to that of tangible assets—changes in measured GDP, which does not include all intangible investments, understate the actual changes in total output. If changes in the labor input are more precisely measured, then it is possible to observe little change in measured total factor productivity (TFP) ...
