Cost and Profit Efficiency of Financial Conglomerates and Universal Banks in Europe
分析欧洲金融集团和全能银行的成本与利润效率，发现全能银行和金融集团比专业银行更高效，支持银行业去专业化趋势，并指出运营效率已成为银行盈利的主要决定因素。
In contrast to the United States, where the banking system has historically been fragmented, the Second Banking Directive allows European banks both to form financial conglomerates and hold equity stakes in nonfinancial companies. This paper analyzes the cost and profit efficiency of European financial conglomerates and universal banks. I find that conglomerates are more revenue efficient than their specialized competitors and that the degree of both cost and profit efficiency is higher in universal banks than in nonuniversal banks. These results indicate that the current trend toward further de-specialization may lead to a more efficient banking system. An investigation of the equity betas under varying business cycle conditions supports the hypothesis of superior monitoring capabilities on the part of universal banks. Finally, profit regressions suggest that operational efficiency has become the major determinant of bank profitability and that oligopolistic rents have become less prevalent in European banking.
