通过在金融资产结构与经济增长模型中引入能够综合反映制度变迁的制度变量,证明国家制度变迁对一国金融资产结构与经济增长会起到促进或制约的作用.当制度供给与金融资产结构和经济增长对制度的需求达到均衡时,国家制度安排会优化金融资产结构、促进经济增长,否则便会出现规模与效率的"反比"现象,从而回答了我国金融资产规模与效率之间为什么出现悖论的问题.我国应积极发展非银行金融机构,实现金融体系多元化,对内开放,满足我国经济对多层次、多样化金融的需求,完善金融市场准入制度,优化市场参与主体结构,促进股票市场和银行协调发展. 相似文献

We investigate the impact of product market competition on returns to skills in Italy using a longitudinal dataset on individual working histories. This impact is identified using three exogenous shocks affecting competition: the unforeseen devaluation of the Lira in 1992, its return to a fixed exchange regime in 1996 and the market liberalisation in the utility and transport sectors in the late 1990s–early 2000s. We analyse how firm heterogeneity and shocks of different types and signs affect the impact of competition on skill premia. We find that opposite shocks have opposite effects: an increase (resp. decrease) in international competition increases (resp. decreases) skill premia. Moreover, international shocks have greater effects on medium sized firms, while domestic liberalisation shocks have greater effects on large incumbents. 相似文献

Approximations to utility indifference prices are provided for a contingent claim in the large position size limit. Results are valid for general utility functions on the real line and semi‐martingale models. It is shown that as the position size approaches infinity, the utility function's decay rate for large negative wealths is the primary driver of prices. For utilities with exponential decay, one may price like an exponential investor. For utilities with a power decay, one may price like a power investor after a suitable adjustment to the rate at which the position size becomes large. In a sizable class of diffusion models, limiting indifference prices are explicitly computed for an exponential investor. Furthermore, the large claim limit arises endogenously as the hedging error for the claim vanishes. 相似文献

In this paper we observe that firm size (SZ) and book-to-market (BM) cannot fully explain stock returns on prior-return- (PR-) based portfolios in the Japanese stock market. The overreaction effect after controlling for the SZ and BM effects is significant and persistent, and accounts for a large part of the zero-investment returns on the loser to the winner. We therefore propose a new mimicking portfolio whose returns mimic the common factor in returns related to overreaction. Our evidence shows that the proposed four-factor model captures common variation in returns on portfolios, based on stocks SZ, BM, and PR, better than the well-known three-factor model does. 相似文献

不同国家、不同历史时期的特大城市人口规模变动极大,运用 Kernel 密度函数对中国城市人口规模分布的分析表明,当前以城区常住人口“500万以上”为特大城市的划分标准是合理的。从城市人口规模变动的动态历程来看,该变动主要受城市产业与经济发展的影响。对中国主要特大城市实有人口规模变动的分析表明,特大城市的人口规模调控应因时因地而动,不能搞一刀切,而且人口调控政策重点应该从数量控制转向结构优化。特大城市转型升级面临着农民工供给短缺、大学毕业生相对过剩、老年和少儿非劳动力人口持续增长等人口新常态约束。在这种人口增长新常态背景下,特大城市应坚持市场化改革方向,促进政府制度创新和企业技术与管理创新是城市转型升级的根本动力。 相似文献

灾害事件、规模与企业慈善捐助:中国背景 总被引:2,自引:0,他引:2
近年来,针对灾害事件的企业慈善行为研究是企业社会责任研究的热点问题。文章主要探讨在中国背景下,不同来源国(地区)的企业针对灾害事件的慈善捐助在数量上有无差异,以及国内企业的慈善捐助数量是否受企业财务状况的约束。通过研究收集到的283家国内企业和428家外资企业在5·12汶川地震后的捐助数据,结果发现:(1)不同来源国(地区)的企业在5·12地震后的捐助水平并无明显差异;(2)国内企业的捐助数量主要受到企业规模而非企业利润(ROA)的影响。 相似文献

Despite an increasing number of hospitality studies on the link between corporate social responsibility (CSR) and corporate financial performance (CFP), the literature has predominantly focused on the CSR–CFP relation without considering moderating factors. Consequently, the current study introduces firm size as a potential moderator on the CSR–CFP relationship. Performing a two-way fixed-effects model by firm and year with Newey-West standard errors, this study finds that firm size moderates the effect of positive CSR on CFP while it does not moderate the effect of negative CSR on CFP in the U.S. restaurant context. 相似文献

Resilience – a firm's ability to adapt, endure, quickly bounce back, and then thrive despite a catastrophic event – addresses diverse managerial constructs including performance (Carmeli & Markman, 2011). Our exploratory study expands this line of research by making two contributions: first, we develop and test a new revelatory measure for resilience – VOLARE – combining financial performance measures with volatility data. Then, applying this new measure to the financial industry, from 2002 to 2011, we identify highly resilient international financial services firms (IFSFs; e.g., banks) and compare them with less resilient IFSFs. Second, we assess three factors – bank size, home-market solidity, and product and market complexity – that the literature has traditionally shown to be highly predictive of banks’ performance. Consistent with our expectations, the results corroborate that VOLARE is complementary to, but distinct from, traditional financial measures of firm performance. We explain these deviations from traditional studies and suggest further research topics. 相似文献

企业规模、规模经济与产业集群 总被引:34,自引:0,他引:34
企业规模问题一直存在着截然相反的观点和主张,造成冲突的原因在于“企业规模”是一个各取所需的含混的概念。具有经济学意义的企业规模应该从两个相互正交的维度上———企业的横向规模和纵向规模———来度量。规模经济来自于横向规模的扩张,而纵向规模的扩张可能会带来规模不经济。产业集群是观察企业横向、纵向规模一个好的样本。区分企业规模的不同性质,将会使与规模经济相关的理论研究出现明晰的路径。 相似文献
