The Effects of Megamergers on Efficiency and Prices: Evidence from a Bank Profit Function 总被引:4,自引:0,他引:4

This paper examines the efficiency and price effects of mergers by applying a frontier profit function to data on bank megamergers. We find that merged banks experience a statistically significant 16 percentage point average increase in profit efficiency rank relative to other large banks. Most of the improvement is from increasing revenues, including a shift in outputs from securities to loans, a higher-valued product. Improvements were greatest for the banks with the lowest efficiencies prior to merging, who therefore had the greatest capacity for improvement. By comparison, the effects on profits from merger-related changes in prices were found to be very small. 相似文献

国有商业银行费用偏好与组织绩效的实证分析 总被引:5,自引:0,他引:5
单一国有产权结构、出资人监督缺位和委托代理问题共同决定了国有商业银行费用扩张偏好.实证结果表明,费用规模扩张侵蚀了出资人利润性收益空间,成为国有商业银行利润率指标偏低的解释因素.因此,国有商业银行制度变迁必然包含能够抑制费用偏好的制度工具创新.政府宏观经济目标的退出可以使出资人硬化利润约束,但在政府效用函数不可能全面退出国有商业银行的现实背景中,通过引进在位寡头之间的竞争可以为国有商业银行利润目标约束硬化提供外在制衡条件;同时,产权多元化改革基础上的银行治理结构完善则是解决委托-代理问题下经营者费用偏好问题的彻底措施. 相似文献

We analyze the effect of ICT and R&D on total factor productivity (TFP) growth across different industries in Sweden. R&D alone is significantly associated with contemporaneous TFP growth, thus exhibiting indirect effects. Although there is no significant short-run association between ICT and TFP, we find a positive association with a lag of seven to eight years. Thus, R&D affect TFP much faster than ICT-investments. We also divide ICT capital into hardware and software capital. To our knowledge, this distinction has not been made in any previous study analyzing TFP at the industry level. The results show that lagged hardware capital services growth is significantly associated with TFP growth. Hence, investments complementary to hardware are needed to reap the long-run TFP effects from reorganizing production. 相似文献

We build a game theoretical model to examine how the level of information advantage of insiders and the competition between insiders and sophisticated investors affect stock price movements and traders’ trading strategies and profits. We show that the competition between insiders and sophisticated investors can reduce the losses of less sophisticated investors, and thus alleviates the disadvantaged position of the less sophisticated investors. Further, traders’ profits are affected by the accuracy of insiders’ private information, and the number of days that insiders have obtained the information in advance. These findings show the importance of information transparency and the role of sophisticated investors in limiting insiders’ trading advantages and mitigating the expropriation of investors by insiders. 相似文献

The UK Brexit vote triggered a new wave of policy developments for a future outside the EU. In this context, we analyse the business performance of English hill and upland farms, characterised by marginal economic conditions but also high nature value (HNV). The analysis aims to help identify farm-level management and policy options for greater economic, environmental and social sustainability. Business performance is measured as technical efficiency and the occurrence and persistence of abnormal profits, estimated through stochastic frontier analysis and static and dynamic panel-data methods. The results help indicate rationales for recent trends including farm enlargement, farm family diversification, and agri-environment scheme entry. The single farm payment is found to be negatively associated with farm technical efficiency while agri-environmental subsidies were positively associated to short-term farm profitability. Farm adaptation and resilience during a period of likely turbulence in external circumstances is discussed in light of these findings, as well as potential parallels with marginal HNV areas across Europe. 相似文献
