WHY HIGH EARNERS WORK LONGER HOURS
July 14, 2006
Many salaried men work longer hours because of an increase in "marginal incentives" to supply hours beyond the standard 40 per week, say researchers Peter Kuhn and Fernando Lozano.
As evidence, the authors note:
- An extra hour beyond 40/week was associated with a 1.2 percent increase in earnings for male workers overall between 1983 and 1985, and with more than a 2 percent increase by 2000-2.
- For salaried workers, the man putting in 55 hours per week in the early 1980s earned a weekly salary of 10.5 percent more than an equivalent worker putting in normal hours.
- By the early twenty-first century, that gap had more than doubled, to 24.5 percent.
- Such pay gaps, or "long-hours premiums," were associated with a markedly wider dispersion of earnings within an occupation between 1983 and 2002.
The authors note that U.S. firms have changed their methods of compensation for skilled, salaried workers over the past quarter century. It could be that longer-than-normal workweeks help firms to produce better products and services in "winner-take-all" type of markets
