The limits of equality: Insights from the Israeli kibbutz

Abstract

What limits the capacity of society to redistribute? What determines the structure of compensation in organizations striving for income equality? This paper addresses these questions by investigating the economic and sociological forces underlying the persistence of the Israeli kibbutzim, communities based on the principle of income equality. To do this, I exploit newly assembled data on kibbutzim and a financial crisis in the late 1980s that affected them differentially. Themain findings are that (1) productive individuals are themost likely to exit and a kibbutz's wealth serves as a lock-in device that increases the value of staying; (2) higher wealth reduces exit and supports a high degree of income equality; and (3) ideology facilitates income equality. Using a simple model, I show that these findings are consistent with a view of the kibbutz as providing optimal insurance when members have the option of leaving. More generally, these findings contribute to an understanding of how mobility limits redistribution, and to an understanding of the determinants of the sharing rule in other types of organizations, such as professional partnerships, cooperatives, and labor-managed firms. © 2008 by the President and Fellows of Harvard College and the Massachusetts Institute of Technology.
