This paper analyzes the effect of cooperation in manufacturing on firms' inclination to collude in the market. Compared to non-cooperation in manufacturing, coordination of the investments in production yields a higher competitive profit. If firms intensify cooperation and produce in a joint plant, this profit is still higher due to lower investment costs. Since firms return to competition after a defection from the collusive agreement, a high competitive profit implies a weak punishment. Collusion is thus more difficult, the closer firms cooperate in manufacturing. Moreover, given competition or collusion in the market, joint production yields the highest profit and welfare.
