Not a Typical Firm: Capital–Labor Substitution and Firms' Labor Shares
òòò½Íø Journal: Macroeconomics
(pp. 34–71)
Abstract
The US labor share has declined, especially in manufacturing and retail. Yet the labor share of a typical firm in these sectors has risen. We introduce a model where firms incur fixed costs to automate tasks. A decline in the price of capital goods used for automation reproduces the observed patterns: large firms automate tasks, reducing the aggregate labor share, while the median firm continues to operate a labor-intensive technology. When calibrating the automation fixed costs to match the observed adoption heterogeneity, the model generates the aggregate and firm-level facts quantitatively in response to lower capital prices, especially in manufacturing.Citation
