We examine operating performance and ownership of joint venture and wholly-owned merchant banks operating in Singapore from the formation of the industry to its maturity. For our sample, joint ventures dominated wholly-owned banks as an organizational form only within the first six years of the industry's life, when there were opportunities for organizational learning and risk sharing by venture partners. Thereafter, new banks were typically wholly-owned subsidiaries and 71% of surviving joint ventures switched to wholly-owned status. Despite their higher mortality rates, we find no evidence of lower performance for joint ventures.
