Managing Export Complexity: The Role of Service Outsourcing
研究法国制造企业如何通过外包市场准入服务来降低出口复杂性，发现外包能解释贸易引力成本差异、影响沉没与固定出口成本，并放大贸易自由化的品种收益。
Abstract As manufacturing firms expand globally, business services such as advertising and legal support become essential for entering new markets. Exploiting exogenous demand shocks, we document that French manufacturers increasingly outsource market-access services as they enter more destinations. We develop a theory of market-access costs in which firms weigh the managerial strain of internal provision against adaptation costs of outsourcing—a mechanism that receives empirical sup-port. Further explorations reveal that outsourcing market-access services helps explain variation in access costs related to gravity and extended gravity, affects both sunk and fixed export costs, and substantially amplifies the variety gains from trade liberalization.
