Despite the claims of efficiency wage theory, there is surprisingly li
ttle direct evidence that firms that pay higher wages have lower turno
ver rates than otherwise similar firms. This study uses data on 205 ch
ild care establishments to examine the influence of wages, fringe bene
fits, and the dispersion of wages within a skill class on establishmen
t quit and fire rates. We separately examine one high-skill group (tea
chers) and one low-skill group (teacher aides). While we find that wag
es (alone) significantly reduce establishment quit and fire rates, the
effect seems too small to be consistent with the efficiency wage hypo
thesis.
