The relationship between employer size and within firm job mobility is investigated. Larger employers are posited to provide their workers with greater options for career advancement within the firm in an attempt to both protect (and encourage) the relatively higher investments in their workers and to evaluate employee performance. Using microdata on actual levels of internal mobility, direct support is found for the propositions of greater internal mobility in larger establishments. Copyright 1989 by MIT Press.
