摘要

尽管再保险公司具有创造巨额利润的已知优势,但现有文献的证据表明,再保险公司的未来需要更加稳健地应对导致业绩不佳的经济缺陷。这背后有很多可能的因素。然而,本研究旨在利用广义矩量法(GMM)模型确定宏观经济因素与非洲再保险公司盈利能力之间的关系。该研究使用了来自48个非洲国家的121家上市再保险公司,使用了2008年至2019年的二手数据。利用传统的最小二乘法和两步系统GMM估计器对1452个观测面板数据集进行了分析。研究表明,GDP、利率和汇率正向影响盈利能力。相比之下,通货膨胀率和货币供应量对盈利能力的影响为负且可以忽略不计。本研究的投入在于为影响非洲上市再保险公司盈利能力的宏观经济因素提供新的证据。

The Relationship Between Macroeconomic Factors and Profitability of Reinsurance Companies in Africa: An Application of System GMM-Model
Despite the known strengths of the reinsurance companies to generate immense profits, evidence from existing literature indicates that the future of the reinsurance companies needs to be more robust to economic deficiencies leading to underperformance. There are many possible factors behind this. However, this study aimed to determine the relationship between macroeconomic factors and the profitability of African reinsurance companies with a Generalized Method of Moments (GMM) model. The study used 121 listed reinsurance companies from 48 African countries using secondary data from year 2008 to 2019. A 1452 observation panel data set was analyzed using conventional least squares and two-step System GMM estimators. The study revealed that GDP, interest rate, and the exchange rate positively impact profitability. In contrast, the inflation rate and money supply revealed a negative and negligible impact on profitability. The input of this research resides in providing new evidence on the macroeconomic factors influencing the profitability of listed reinsurance companies in Africa.
