Optimal Adoption of Complementary Technologies
Jovanovic, Boyan, and
Dmitriy Stolyarov. 2000. "Optimal Adoption of Complementary Technologies."
American Economic Review,
When a production process requires two extremely complementary inputs, conventional wisdom holds that a firm would always upgrade them simultaneously. We show, however, that if upgrading each input involves a fixed cost, the firm may upgrade them at different dates, "asynchronously." This insight helps us understand why productivity rises with the age of a plant, why investment in structures is more spiked than equipment investment, and why plants have spare capacity. The bigger point of the paper is that complementarity does not necessarily imply comovement--not even for a single decision maker.
