O-Ring Production Networks
研究了土耳其企业生产网络中的技能匹配现象，发现来自富裕国家的出口需求冲击会提升企业的技能密集度和与技能密集型国内伙伴的贸易，并通过量化模型揭示这种网络效应使工资增长效应放大九倍。
We document strong skill matching in Turkish firms’ production networks. Additionally, in the data, export demand shocks from rich countries increase firms’ skill intensity and their trade with skill-intensive domestic partners. We explain these patterns using a quantitative model with heterogeneous firms, quality choices, and endogenous networks. A counterfactual economy-wide export demand shock of 5% leads both exporters and nonexporters to upgrade quality, raising the average wage by 1.2%. This effect is nine times the effect in a scenario without interconnected quality choices. We use the model to study the conditions for the success of export promotion policies.
