Export Dynamics: Evidence from the Global Mobile Phone Industry时间：11月17日（周三）14:00-15:30地点：承泽园246教室主讲人: 谢晓晨主持人：（国发院）李力行、席天扬、张晓波（经济学院）刘冲摘要：This paper studies firms' export dynamics using evidence from the global cellphone industry. Exporters tend to enter foreign markets that are geographically close or culturally similar to their previous export destinations. Most structural work of international trade has ignored firms' sequential export decisions across countries when estimating entry costs or has failed to build a framework in which firms' export-dynamic actions can be tractable or in which entry costs can be accurately estimated. I build a dynamic model in which firms first sequentially choose global regions for penetration and then spread out over the countries in the regions. I estimate firms' region- and country-level entry sunk costs for starting a business and the country-specific fixed costs for maintaining operation. I find that entering a new region with consumer characteristics similar to the previous export regions could reduce the entry costs as drastically as 81%. Relatedly, adding countries after penetrating a region would incur much lower entry costs than the costs associated with entering the first country in that region. Stricter trade regulation in large countries, such as the G7 group, would also reduce importers' entry margins and their trade value in the surrounding, smaller European countries. Moreover, conditional on the same productivity level, the geographical location of a firm's headquarters could determine as much as 70% of the variation in global expansion and sales. My model primitives predict a world with more advanced infrastructure, which can shorten the world's distance by half, could reduce delivery cost, and greatly enhance the consumer surplus in the mobile phone market by 1.3% to 3.87%. Compared to a static model, my dynamic model reports a gradual and less volatile increase in consumer surplus and market competition.个人简介：谢晓晨，中国人民大学财政金融学院财政系助理教授，中国人民大学杰出学者青年学者。他于2013年7月分别获得北京大学光华管理学院金融学学士学位和北京大学数学科学学院统计学学士学位；2014年12月获得美国威斯康星大学麦迪逊分校经济学硕士学位；2021年5月获得美国宾夕法尼亚州立大学经济学博士学位，博士论文指导教师为国际贸易经济学家Jonathan Eaton教授。他目前的主要研究领域为公共财政，国际贸易，产业组织和城市与区域经济学。他的主要研究兴趣是通过实证回归分析和结构模型模拟，评估政府政策和公共项目对企业行为和宏观经济的影响。
