PublicationThe Structure of the Global Reinsurance Market: An Analysis of Efficiency, Scale, and ScopeWe estimate economies of scale and scope as well as cost and revenue efficiency to explain the structure of the global reinsurance market, where large reinsurers dominate but both diversified and specialized reinsurers are competitive. The costs and benefits of size and product diversification are particularly relevant to the reinsurance industry, as risk diversification is central to the industry's business model. We find that reinsurers with total assets less than USD 2.9 billion exhibit scale economies, while those with total assets greater than USD 15.5 billion do not. Large reinsurers are characterized by high cost efficiency, while small reinsurers exhibit superior efficiency only when specialized. Large reinsurers also exhibit revenue scope economies when operating both life and nonlife reinsurance. Moreover, the evidence is in line with the efficient structure hypothesis: cost-efficient reinsurers can charge lower prices without sacrificing profitability.Type:Journal:Volume:

PublicationThe Determinants of Efficiency and Productivity in the Swiss Insurance IndustryUsing state-of-the-art frontier efficiency methodologies, we study the efficiency and productivity of Swiss insurance companies in the life, property/casualty, and reinsurance sectors from 1997-2013. In this context, we provide the first empirical analysis of internationalization strategies of insurance companies, a topic of high interest in the business and economics literature, but one that has to date not been the focus of efficiency studies in the insurance sector. We find that productivity and efficiency have improved with regard to property/casualty and reinsurance. In the case of life insurance, productivity and efficiency diminished; however, life insurance firms with higher levels of international business exhibit superior efficiency levels. We observe that diversification strategies directed to the European market are more beneficial compared to those targeting markets outside of Europe.Type:Journal:Volume:Issue:

PublicationAn Efficiency Comparison of the Non-life Insurance Industry in the BRIC Countries(Elsevier, 2013-05)We analyze the efficiency of non-life insurance companies in four of the fastest-growing markets in the world-the BRIC (Brazil, Russia, India, China) countries. An innovative feature of this paper is its incorporation of uncontrollable variables in the efficiency analysis using multi-stage data envelopment analysis (DEA). This approach captures cross-country differences, such as the political and economic environment, and allows distinguishing between managerial inefficiency and inefficiency due to environmental conditions. We find that the environment affects the efficiency of non-life insurers operating in the BRIC countries. Furthermore, in a regression of firm characteristics on efficiency scores we identify four drives of efficiency: Size, profitability, solvency, and ownership form. The results further our understanding of the insurance industry in the BRIC countries in regard to its efficiency and the environment in which it operates.Type:Journal:Volume:Issue:

PublicationEfficiency in the International Insurance Industry : A Cross-Country Comparison(Elsevier, 2010-07-01)The purpose of this paper is to provide new empirical evidence on frontier efficiency measurement in the international insurance industry, a topic of great interest in the academic literature during the last several years. A broad efficiency comparison of 6462 insurers from 36 countries is conducted. Different methodologies, countries, organizational forms, and company sizes are compared, considering life and non-life insurers. We find a steady technical and cost efficiency growth in international insurance markets from 2002 to 2006, with large differences across countries. Denmark and Japan have the highest average efficiency, whereas the Philippines is the least efficient. Regarding organizational form, the results are not consistent with the expense preference hypothesis, which claims that mutuals should be less efficient than stocks due to higher agency costs. Only minor variations are found when comparing different frontier efficiency methodologies (data envelopment analysis, stochastic frontier analysis).Type:Journal:Volume:Issue:
