DEA Window Approach to Analyze Trends in Efficiency of Angolan Insurance Companies
Year: 2025
Type: article
Abstract: The objective of this study is to analyze trends in scale efficiency scores in the insurance sector in Angola, related to its ability to minimize resources to maximize results. The methodology followed was the DEA window analysis, which allowed, on the one hand, to compare the efficiency scores recorded with their average, allowing to section in time, periods of analysis of the trend in the efficiency scores of eleven Angolan insurers. From the analysis carried out, it was possible to identify the least efficient insurers in the period (2019-2023). Despite a slight downward trend, it was also possible to verify that between the first and second windows (2019-2022), the insurers presented homogeneous efficiency scores, indicating efficiency averages, for this period, quite similar for the set of insurers that were part of the sample. Finally, it was possible to determine that none of the insurers analyzed recorded, in the period (2019-2023), an efficient average score.
