非银行部门发展对经济增长的影响:一种夜间灯光数据方法
Non-Banking Sector development effect on Economic Growth. A Nighttime light data approach
AI总结:
本文利用夜间灯光数据研究南非保险业等非银行部门与经济增长的关系,发现保险部门对经济发展预测力更强,且夜间灯光数据比GDP更能反映新兴经济体的经济增长。
摘要:
本文使用夜间灯光(NTL)数据来衡量南非非银行部门(尤其是保险业)与经济增长之间的关联。我们假设保险部门的增长因其具有投资保护和最优风险缓释等有利于经济增长的特征而对经济增长产生正向推动作用。我们还主张,夜间灯光数据是比国内生产总值(GDP)更好的经济衡量指标。我们使用加权回归来衡量夜间灯光数据、GDP 与保险部门发展之间的关系。我们使用了从世界银行收集的2000年至2018年期间的南非GDP时间序列数据,以及来自美国国家地球物理数据中心(NGDC)与美国国家海洋和大气管理局(NOAA)合作提供的夜间灯光数据。根据所拟合的模型以及报告的BIC、AIC和似然比,保险部门被证明对南非经济发展具有更强的预测能力,并且辐射亮度灯光比GDP和人均GDP更能解释经济增长。我们得出结论:在南非等新兴经济体中,夜间数据是比人均GDP更好的经济增长代理指标,因为这些经济体的二手数据需要更加稳健,有时还会被夸大。这些发现将指导研究人员和政策制定者了解什么因素驱动经济发展以及应制定哪些政策。将当前研究扩展到其他部门(如微型金融、共同基金和对冲基金)将是有意义的。
英文摘要:
This paper uses nighttime light(NTL) data to measure the nexus of the non-banking sector, particularly insurance, and economic growth in South Africa. We hypothesize that insurance sector growth positively propels economic growth due to its economic growth-supportive traits like investment protection and optimal risk mitigation. We also claim that Nighttime light data is a good economic measure than Gross domestic product (GDP). We used weighted regressions to measure the relationships between nighttime light data, GDP, and insurance sector development. We used time series South African GDP data collected from the World Bank for the period running from 2000 to 2018, and the nighttime lights data from the National Geophysical Data Centre (NGDC) in partnership with the National Oceanic and Atmospheric Administration (NOAA). From the models fitted and the reported BIC, AIC, and likelihood ratios, the insurance sector proved to have more predictive power on economic development in South Africa, and radiance light explained economic growth better than GDP and GDP/Capita. We concluded that nighttime data is a good proxy for economic growth than GDP/Capita in emerging economies like South Africa, where secondary data needs to be more robust and sometimes inflated. The findings will guide researchers and policymakers on what drives economic development and what policies to put in place. It would be interesting to extend the current study to other sectors such as micro-finances, mutual and hedge funds.
