α: calibrated so average coauthorship-adjusted count equals average raw count
In Lancashire cotton spinning in the heyday of laissez-faire capitalism the labor market did not operate as an auction market. Evidence on piece-rate flexibility, length of tenure, and seniority is consistent with Okun's contract approach. Both workers and firms incurred initial set-up costs. Workers wanted to protect their initial investments in training, and firms, faced with a labor supply that varied in reliability and regularity, had a desire to cover initial hiring and tryout costs. The need to maintain long-term attachments had implications for wage and employment adjustment and the age structure of the labor force.
