Over the past three decades, China has undergone tremendous economic and social change as a consequence of the transition from a centrally planned to a market economy. This paper examines a key feature of this transition – the privatization of the state‐owned enterprises (SOEs) – through both a theoretical model and empirical analysis. Using newly collected primary data from a variety of sources, we study how privatization of listed SOEs affects employment, wages, profits and other aspects of economic performance at the firm level. Our major finding is that privatization results in substantial downsizing of employment, increased labour productivity and rising profitability.  相似文献

The paper studies the interaction between aggregation and persistence pertaining to skip sampling of stock variables as well as temporal aggregation of flow variables for the generalized fractional processes. We show that, for skip sampling, the long memory feature at the zero frequency can arise from the aggregation of a generalized fractional series, while temporal aggregation does not induce such phenomenon. Simulation results are included to demonstrate the practical relevance of the theoretical results.  相似文献

The call options theory of corporate security valuation is applied to narrow-banking contingent claims of one bank, while the cap options theory is applied to synergy-banking contingent claims of another bank. This article investigates efficiency gains specified as equities of scope associated with the likelihood of the two banks involved in merger under capital regulation. We find that merger incentives are encouraged when the narrowing banking is conducted by the consolidated bank, whereas discouraged when the synergy banking is conducted. Raising bank capital requirement leads to an increased interest margin of the consolidated bank with the narrow banking valuation; however, to a decreased margin of the consolidated bank with the synergy banking valuation. An increase in the capital regulation reduces the merger incentives in the narrow banking valuation whereas increases the merger disincentive in the synergy banking valuation. These findings are consistent with the organizational theory that predicts a comparative advantage of narrow banking proposals in bank mergers.  相似文献

Over the past 30 years, China has fully exploited its advantage to steadily foster an innovation system for the biomedical industry with Chinese characteristics, that is, ‘Government-guided, resource-integrated and long-term planning.’ The system originated from historically famous ‘863 program’ in the 1980s, evolved with a series of favourable policies in the different periods, and eventually has taken shape in the industrial clusters across the country. It features with a systematic and integrated R&D infrastructure (or public platform) at different levels. In this study, China’s biomedical innovation system will be examined and the leading role of Chinese authorities will be explored from the perspective of Triple Helix theory. As the ‘highland of innovation’, Shanghai case is highlighted with plentiful information gathered from primary sources in the involved agencies for the first time, including the Shanghai Biopharma Service Platform.  相似文献

从20世纪后半期开始,印刷术时代没落,随之而来的是电视、广播、互联网乃至手机媒体的蒸蒸日上。以手机为代表的新媒体开始以全时、全速、全域、全民的特点充斥在快速成长的青少年生活中,青少年作为主流文化消费者在文化消费中所表现出来追求时尚、注重体验、忽略发展性消费的特点在一定程度上对传统文化家庭的消费决策产生影响。这种影响从根本上不可逆转地改变了传统家庭交流方式,家长被青少年感染,变身孩童化大人,青少年在相对自由的环境中真正得到了身份认同。由此看来,青少年的流行风格与传统家庭文化的碰撞,技术的发展和创新有利于推动传统文化机制的现代化创新。  相似文献

This article proposes using credibility theory in the context of stochastic claims reserving. We consider the situation where an insurer has access to the claims experience of its peer competitors and has the potential to improve prediction of outstanding liabilities by incorporating information from other insurers. Based on the framework of Bayesian linear models, we show that the development factor in the classical chain-ladder setting has a credibility expression: a weighted average of the prior mean and the best estimate from the data. In the empirical analysis, we examine loss triangles for the line of commercial auto insurance from a portfolio of insurers in the United States. We employ hierarchical model for the specification of prior and show that prediction could be improved through borrowing strength among insurers based on a hold-out sample validation.  相似文献

This paper derives the impacts of legal system characteristics and auditing standards on auditor behavior (audit quality), and analyzes the determination of optimal auditing standards under different legal regimes. Legal regimes are characterized by differences in the uncertainty concerning the outcome of legal proceedings (termed vagueness of legal systems) and differences in the average size of damage awards. Auditing standards as determined by standard setters can vary in both toughness and vagueness. Our analysis provides implications for the adoption of International Standards on Auditing (ISA). Countries, such as the United States, where auditor legal liability is significantly more onerous than the global norm are not likely to adopt ISA, since these standards may not induce auditors to provide the optimal level of audit quality. Conversely, the adoption of ISA by countries, such as China, where the legal system makes the recovery of damages from auditors quite difficult, is not by itself likely to result in a high level of audit quality. Furthermore, our model suggests that auditor rotation can help improve audit quality, but only in certain circumstances.  相似文献
