论文摘要
通过充分考虑进口肉类征收的独特关税制度，我们估计日本两阶段进口聚合功能的牛肉，鸡肉和猪肉的替代弹性。虽然回归分析至关重要地取决于消费者面临的价格，但进口肉类的订婚后价格不仅取决于货车职责，还取决于关税率配额和门价格系统制度。因此，通过使用每月交易数据来评估有效的关税率。为了解决潜在的内生性问题，我们应用了我们认为与进口肉的需求冲击无关的汇率。数据的面板性质使我们能够通过时间虚拟变量（无需冲击）来检索第一阶段的聚集体，用作解释变量的一部分，并在第二阶段回归中用作仪器。
By fully accounting for the distinct tariff regimes levied on imported meat, we estimate substitution elasticities of Japan's two-stage import aggregation functions for beef, chicken and pork. While the regression analysis crucially depends on the price that consumers face, the post-tariff price of imported meat depends not only on ad valorem duties but also on tariff rate quotas and gate price system regimes. The effective tariff rate is consequently evaluated by utilizing monthly transaction data. To address potential endogeneity problems, we apply exchange rates that we believe to be independent of the demand shocks for imported meat. The panel nature of the data allows us to retrieve the first-stage aggregates via time dummy variables, free of demand shocks, to be used as part of the explanatory variable and as an instrument in the second-stage regression.
