The Role of Firms in Immigrant Assimilation and Labor Market Adjustment

描述(申请人提供)：本提案的主要目标是了解移民和企业在经济中如何互动，以及这种互动如何影响移民的成功和本地出生的流离失所。我们的具体目标是：(1)利用新开发的纵向雇主-雇员匹配数据集(在人口普查的Lehd项目中)的面板性质来描述工资同化率。工资趋同的速度是否因抵达日期而异？收敛速度是否因原籍国不同而不同？(2)解释哪些因素与移民的工资收敛速度有关？雇用移民的公司的特点有助于解释工资同化吗？例如，来自移民母国的工人集中、公司规模和公司的其他生产特征是否会改变工资趋同的速度？移民抵达美国后所做的就业选择是否会影响移民的长期前景？(3)探索本地出生的工人在应对来自移民工人的竞争时的相对成功或失败？一个行业的人力资本水平或任期等员工特征的重要性有多大？企业的选择，如技术类型或工人组合的变化，对移民流动对本地出生的工人的影响有多大影响，(4)描述本地出生的工人从公司中转移的情况。当一家公司开始雇佣移民时，哪些土生土长的工人离开了公司？例如，是年长的还是年轻的工人，或多或少在公司拥有终身职位的工人？(5)描述被取代的土生土长的工人会发生什么。他们在相关行业的其他公司工作吗？他们会迁移到其他地方吗？

DESCRIPTION (provided by applicant): The primary objectives of this proposal are to understand how immigrants and firms interact in the economy and how this interaction affects both immigrant success and native-born displacement. Our specific aims are: (1) To describe the rate of wage assimilation exploiting the panel nature of the newly developed longitudinal employer-employee matched data-sets (in the LEHD project at Census). Does the rate of wage convergence vary by date of arrival? Does the rate of convergence vary by country of origin? (2) To explain what factors are associated with the rate of wage convergence of immigrants? Do the characteristics of firms that employ immigrants help explain wage assimilation? For example, does the concentration of workers from the immigrant's home country, the size of firm and the other productive characteristics of firms change the rate of wage convergence? Do employment choices that immigrants make upon arrival in the U.S. affect the long-term prospects of immigrants? (3) To explore the relative success or failure of native-born workers to respond to competition from immigrant workers? How much do worker characteristics such as the level of human capital or tenure in an industry matter? How much do firm choices such as changes in the types of technology or worker mix matter for the impact of immigrant flows on native born workers, (4) To describe the displacement of native-born workers from firms. When a firm begins to hire immigrants which native-born workers exit the firm? For example is it older or younger workers, workers with more or less tenure with the firm? (5) To describe what happens to displaced native-born workers. Do they work for other firms in related industries? Do they migrate to other locations?
