Empirical issues concerning studies of firm entry
讨论了企业进入可从企业家、企业、行业和国家等多个层面分析，并列出六项计量研究挑战，强调需要更详细的数据来研究孕育过程、进入模式及资源与知识禀赋的价值。
Abstract We discuss that entry can be considered from various levels of analysis: entrepreneur-level, firm-level, and also at higher levels of aggregation, such as the industry-level and country-level. We also formulate a list of six challenges for econometric studies of firm entry, highlighting the data sources, typical empirical setups, potential sources of bias, and appropriate econometric techniques. While progress can be made with sophisticated econometric estimators, a pressing need for entry studies concerns detailed data on the gestation process, entry modes, and the value of resource endowments and knowledge endowments.
