碩士 === 國立政治大學 === 會計研究所 === 93 === The risk-based capital (RBC) requirements developed by the National Association of Insurance Commissioners (NAIC) were intended to raise the safety net for insurers and to provide regulators with the authority to intervene when capital falls below a minimum standard of capital adequacy that is related to risk. Since the less functional barrier of financial service and the greater competition among the property-liability insurers which forced the property-liability insurers to find a balance between solvency and efficiency so that the insurers can have enough cost efficiency and keep maintaining adequate non risk assets as well as rising shareholders’ equity. Therefore, the purpose of this research is to examine the cost efficiency change after property-liability insurers applied RBC standards. To do this, we examine 372 property-liability insurers’ data from 1990-1998 and compare the efficiency change before and after 1994, the RBC standards effective year. This study applies Data Envelopment Analysis and uses the grand frontier approach to measure the cost, allocative and technical efficiency. The statistical results reveal that after applied RBC standards cost and allocative efficiency had significant decline, but no change in technical efficiency. The Tobit regression statistical results indicate that the product concentration has a negative effect on cost efficiency and allocative efficiency; and the market share has a negative relationship with cost efficiency, technical efficiency and allocative efficiency. Cost efficiency and allocative efficiency of incorporate companies are higher than that of mutual companies. Furthermore, the positive relationship between the firm size and efficiency suggested that the larger the size the better efficiency. Overall results imply property-liability insurers may be forced to adjust their investments risk, however, such adjustment might be contributed to less cost and allocative efficiency after applied to RBC standards requirements.
