We therefore obtain the following solution for the investment choices under employee
cooperative.
Lemma 14 If f' > 1, the equilibrium human capital investment levels under employee
cooperative are given by:
.Ec _ an ff ∖i , ʌ" I ɪ " ɑo

Outside ownership
When f, ≥ 1 the bargaining solution under outside ownership is given by:
Agent: employee E1 employee Ern employee Eb outside owner Oi customer Cij
share: Vrl-V3 vm - υb 0 V2 - υm vb
„ . . Agent: employee E2 emplovee Ern employee Eb outside owner Oi
customer C
υb
if the firm hires Ei : or
share: υ2 — vb vm -vb O V2 + vb — v2 — υm
if the firms hires E2.
These payoffs then translate into the following ex-ante investment choices for the em-
ployees. When ff > 1 theʌ* choose klj to maximize:
max (≥i [f (λ1 log(l + fcy)) + Λ2 log(l + kij}] + log(l + ⅛y) - kij) (18)

We thus obtain the following solution for the investment choices under outside owner-
ship.
Lemma 15 The equilibrium human capital investment levels under outside ownership are
given by
k° = ɪ √'λ' + < + - 1∙ iff' ≥ 1∙
That is. when the complementarity is strong, the outside ownership will under-invest.
Customer Cooperative
Wlien ∕' ≥ 1 we have:
Agent: employee F1 employee Em employee Eb customer-owner C
share: V1 - V3 ' υm - υb O V2 + vb - vm
