摘要 Abstract of the Paper	This paper develops a dynamic timing game of outsourcing adoption in vertically related markets. Two vertically integrated firms, initially producing with in-house inputs, may outsource to specialized contractors through Nash bargaining over two-part tariff contracts. We show that outsourcing timing depends critically on in-house production costs and product market competition. When in-house costs are low, both firms outsource simultaneously, generating clustering of adoption and profits below those under no outsourcing, a prisoner’s dilemma. When in-house costs are high, outsourcing occurs sequentially, with the leader enjoying a first-mover advantage. We further show that neither higher product-market competition nor higher in-house costs necessarily induce earlier outsourcing. Extensions demonstrate that centralized bargaining accelerates outsourcing relative to decentralized bargaining, while exclusive input relations delay adoption. Welfare analysis shows that firms typically outsource too late, as they internalize only private profits and neglect the impact on consumer surplus and the rival’s profits.
