Cyclical Skill-Biased Technological Change

Over the past two decades, technological progress has been biased towards making skilled labor more productive. What does skill-biased technological change imply for business cycles? To answer this question, we construct a quarterly series for the skill premium from the CPS and use it to identify skill-biased technology shocks in a VAR with long run restrictions. We find that hours worked fall in response to skill-biased, but not in response to skill-neutral improvements in technology. Skill-biased technology shocks are associated with increases in the relative price of investment, indicating that capital and skill are substitutes in aggregate production.
