摘要:我们构建一个包含异质性主体和本地空间市场的模型去研究银行扩张,经济增长,和收入不平等之间的联系。在模型中,每个家庭要选择他们的职业,消费水平,信贷,并在具有不同流动性的资产间进行配置。银行要选择新开设分支机构的地点,这些机构进而对在不同区域中各个家庭面临的金融摩擦产生影响。我们运用地理信息系统校准模型的参数,对泰国在1986至1996年的快速银行扩张给出分析。模型定量的分析了导致这一时期经济增长与不平等随时间和空间变化的根源,并量化了引入数字银行所可能产生的区域异质性降低。
Abstract:We develop a heterogeneous-agent model with local spatial markets to study the relationships among bank expansion, growth, and inequality. In the model, households choose their occupations, consumption, and holdings of loans and portfolio assets that vary by liquidity. Banks choose the locations of new branches, which affect the financial frictions facing households across regions. We calibrate the model using a geographic information system to evaluate the rapid bank expansion in Thailand between 1986-1996. The model quantifies the sources of growth and inequality over time and across space and the potential role of digital banking in substantially reducing regional heterogeneity.
