生产网络中的供应商匹配：一个定量分析框架
Matching to Suppliers in the Production Network: a Quantitative Framework
摘要
We build a model of production network formation that enables econometric estimation of the determinants of supplier choice, like trade costs or matching frictions. The model informs an estimator obtained from a transformation of the multinomial logit likelihood function that conditions on two network statistics: the out-degree of sellers (a sufficient statistic for the seller marginal costs) and the in-degree of buyers (which is determined by decisions of buyers, like “make-or-buy”). In an empirical application, this estimator shows that a prominent Costa Rican highway fostered firm-to-firm connections between core and peripheral regions, and within the core regions themselves.
中文摘要
我们构建了一个生产网络形成模型，该模型能够对供应商选择的决定因素（如贸易成本或匹配摩擦）进行计量经济学估计。该模型指导了一种估计方法，该方法通过对多项逻辑似然函数进行变换获得，并基于两个网络统计量进行条件设定：卖方的出度（作为卖方边际成本的充分统计量）和买方的入度（由买方决策决定，如“制造或购买”）。在一项实证应用中，该估计方法表明，哥斯达黎加一条著名的高速公路促进了核心区域与边缘区域之间，以及核心区域内部的企业间联系。
