Received F’ebruarv :’983, final version received December 1983 Simple, organiqatio~ .c~rnpwed of qxxathes and one manager, may be organiz& as a l&w&r I@ the manti@r appropni&g ali profits or as a partnership with (say) qua f shares of @of&. Conditions 8n 1&Wit&& ty md foe optimal span of control a-~ arz_$z 9. Next, partnerships are considered and alkrnlltive incentives and distributions aw wmpar 1. When partners are free to choose their time inputs, then a sufficiently high preference for leisure as against income will rwke a partnership more attractive even though it is less !.wofitabie.

orgtizations are engaged in activiti~:s that could also k individuals, &en &I things beyond the scope of in&iduaf df~rt. III ~ZBY ~~orgaxkiz~ti~s face the task of coordinating the activities of their men&m. This act,i,ity coordination WiB be called manageme%;. in add&ion, m&mgement com;prises other planning tasks that even an individual operating on his/her own cannot escape from. Coordination re@iir~~~~ntro~. In a sirnpi~ organization (one with only two ieve&) this control mast be: centralize4i in a single person. Tlhis person may also perform $ome operative work, but the managemen”, task cAnnot be divided among several persons. The only way to retain soxne equality in an organizatiort is to rotate the management fi~nction periodically. Moreover, some choice exists a.bout the way iti M&S the o~ga&ation% profits are to be d+&ibuted, There ;appe%rto be two extremes among the possible arrangements which we shall label hierarchy and partnership respe::fively. In a hierarchy the managemerIt function is assignexi permanently to one person who also glairns the entire profits. The other extreme is that of an equal sharing of the managemen; function through rotation and of profits thl:ough an equal divisiicrn. Sixe both types occur in r~z4 We (stfthougfn the hierarchical tym mcch mom frequetitly) we want to study con&tions tinder which one or-the other foral of organization is prefi$rable. The questiou has recently come to the attent& ftr of econotiists and hg!s been addressed also by Williamson ( EW), @a!~ (19’79), Putterman (1981a, b) and Rosen. (15381). Our emphasis will h c+n ef%ciency as revealed by a production function. pdormed
