The Geographic Concentration of Enterprise in Developing Countries
研究泰国企业地理集中对区域增长的影响，发现企业高集中度预测本地及周边增长，但存在空间收敛和停滞区域，并构建模型解释职业转换与金融扩张的作用。
A nation's economic geography can have an enormous impact on its development. In Thailand, we show that a high concentration of enterprise in an area predicts high subsequent growth in and around that area. We also find spatially contiguous convergence of enterprise with stagnant areas left behind. Exogenous physiographic conditions are correlated with enterprise location and growth. We fit a structural, micro-founded model of occupation transitions with fine-tuned geographic capabilities to village data and replicate these salient facts. Key elements of the model include costs, credit constraints on occupation choice, and spatially varying expansion of financial service providers.
