Integration and Productivity: Satellite-Tracked Evidence
利用一家大型渔业公司管理其垂直、水平和地理关联船只的卫星追踪实时数据，研究收购未整合的合同供应商后，整合对全要素生产率（TFP）的因果影响。新整合船只的TFP提高了16%，而知识转移和层级权威实施改进运营实践是更可能的解释。
This paper introduces satellite-tracked real-time data from a large fishing firm managing its vertically, horizontally, and geographically linked ships to study the causal impact of integration on total factor productivity (TFP) after the firm acquired its vertically unintegrated contractual fish suppliers. TFP increased 16% among newly integrated ships, whereas it did not vary for already owned ships. Some classic mechanisms such as increased effort due to monitoring do not systematically explain TFP gains under integration, whereas evidence on hold-up threat alleviation is mixed. Importantly, enhanced knowledge transfer and hierarchical authority enacting productivity-improving operational practices among newly integrated ships are more likely explanations of the results.
