We study the implications of microeconomic heterogeneity for aggregate technology, showing that the aggregate elasticity of substitution between capital and labor can be expressed as a simple function of plant level structural parameters and sufficient statistics for plant heterogeneity. This...

We compute rates of growth in labor productivity during the 1973-80 period for samples of individual manufacturing firms, in both Japan and the U.S., and relate them to differences in the rates of growth in their capital-labor ratios and in their intensities of R&D effort. Japanese firms spent...

The decline in the U.S. labor share is far from uniform across firms. While the aggregate labor share has declined, especially in manufacturing, retail, and wholesale, the labor share of a typical firm in these industries has risen. This paper studies the dynamics of the substitution of capital...

This paper has three main objectives. First, it examines the level of multifactor productivity (MFP) in Canada relative to that of the United States for the 1994-to-2003 period. Second, it examines the relative importance of differences in capital intensity and MFP in accounting for the labour...
