A Half-Century of US Labor Data Shows Steady Retreat From Evening and Night Work

Despite the popular notion that the modern economy runs around the clock, a new NBER working paper analyzing fifty years of U.S. labor data from 1973 to 2023 finds that Americans have been steadily and consistently moving away from evening and night work toward traditional daytime hours [PDF]. The share of the workforce on the job at 11PM, for instance, fell by over 25% from its 1970s level. Economists Jeff Biddle and Daniel Hamermesh argue the primary driver is rising real incomes -- night work is essentially an inferior good that workers avoid as they earn more. The wage premium employers must pay for undesirable hours has grown by about three percentage points over the period. One sector bucked the trend: retail, where the rise of big-box chains, 24-hour Walmart supercenters and overnight distribution center restocking pushed more employees into late-night and early-morning shifts. The Covid-era surge in telework, rather than spreading work across the day, actually accelerated the concentration into prime hours -- especially among college-educated workers. France showed a similar pattern of daytime compression over 1966-2010, but the U.K. did not, likely because rapid de-unionization there eliminated the union wage premiums that had made night work comparatively attractive.
