Firm heterogeneity and endogenous regional disparities
利用罗马尼亚企业普查数据，通过分解企业层面产出动态，分析1996-2001年转型期区域差异的微观来源，发现差异主要源于在位异质性企业的重组活动与初始经济活动分布的相互作用。
We exploit the census of Romanian firms in order to provide a microfounded analysis of the sources of regional disparities in the country during the transition period, 1996–2001. To this extent, we adapt to the regional case a decomposition of firm-level output/value added dynamics based on semi-parametric productivity estimates. The methodology, robust to different techniques of TFP estimation, allows us to analyse the sources of regional disparities controlling for the heterogeneity in firms' characteristics. We find that the emergence of regional disparities is to a large extent endogenous to the interaction between the restructuring activity of incumbent heterogeneous firms and the initial distribution of economic activities. A lesser role is played by the standard drivers of firms' and workers' cross-regional reallocation.
