关于输配电价几个重要问题的探讨

我国电力企业将要由传统的垂直垄断的模式转变为网厂分开、竞价上网的模式。电网公司作为一个独立的经营实体分离开来,有着独立的收益需求。在市场运营过程中,通过输配电价取得收益就成了电网公司取得收益的主要手段。在输配电价的制订过程之中,管制方式、输配电成本、输电定价方法、价格水平及电网投资、输配电价价区、电网提供的辅助服务等六个问题十分重要。文中就这六个问题的解决作了一些有价值的探讨。     

Social networks in the global banking sector

We show that banks with shared social connections partner more often in the global syndicated loan market and that central banks in the network play dominant roles in various interbank transactions, indicating that social connections facilitate business connections. However, more centralized banks in the network also contribute significantly to the global systemic risk. Moreover, we find the soft information generated by social networks is particularly valuable when potential partners operate under different accounting and regulatory standards. Finally, we show that the recent banking crisis significantly limited the positive soft information effects of social networks in the global banking system.     

Responsiveness of Auditors to the Audit Risk Standards: Unique Evidence from Big 4 Audit Firms

We examine the effect of changes in audit risk standards on the conduct of financial statement audits in a European setting. We investigate this by analysing the audit hours and audit fees for clients of Big 4 audit firms in Finland in 1996 and 2010. Our results show that audit firms became more sensitive to clients’ business risk due to the introduction of the new audit risk standards, with more audit hours allocated to owner-managed companies in 2010 than in 1996, and fewer audit hours allocated to low-risk clients in 2010 than in 1996. Also, the labour mix in the audit team changed for owner-managed companies, with a greater work load carried by junior auditors in 2010 than in 1996. Regarding the price of audit, we find an increase in audit fees for clients with high business risk, while audit fees remained at roughly the same level for low-risk clients. These findings should be of interest to the auditing profession and those involved in the development of auditing regulations.     

会计管制研究梳理及评论

文章主要介绍了国内外学者围绕会计管制的内涵界定、影响因素、经济后果、国际趋同以及公司治理与会计欺诈交叉研究等研究成果。在文献梳理中发现：我国的会计管制研究内容分散且观点存在分歧，仍停留在中心问题的边缘地带，对问题实质之处的挖掘还不够深入。西方理论界对会计管制的研究起步早、范围广，为国内学者提供了理论框架、技术方法等方面的研究指导，安然事件后《萨班斯法案》的出台，更引发了对会计管制的研究热潮。通过对会计管制研究进行脉络梳理和评论，以促进我国会计管制的广角研究。     

Competition,firm size and returns to skills: Evidence from currency shocks and market liberalisations

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.     

The design of light-handed regulation of airports: Lessons from experience in Australia and New Zealand

The difficulties experienced with traditional forms of economic regulation of airports involving direct control of prices have led to an interest in light-handed regulatory frameworks. Experience with light-handed regulation of airports is primarily confined to Australia and New Zealand. The paper examines the design features of light-handed regulation in Australia and New Zealand in relation to the stated objectives associated with the introduction of light-handed regulation. The paper identifies important aspects associated with the design of light-handed regulation including the incorporation of a credible threat of stronger regulation and the characteristics of this, and an apparent trade-off in objectives achieved with different approaches to light-handed regulation.     

异质性环境规制、技术创新与中国工业绿色化

基于中介效应模型和2007~2016年中国省际面板数据，构建异质性环境规制、技术创新与工业绿色化的作用机理理论分析框架，并通过构建异质性环境规制指标体系和工业绿色化指标体系将异质性环境规制与技术创新驱动工业绿色化的作用机理进行实证检验。研究发现：行政型环境规制对工业绿色化起抑制作用，不存在技术创新中介效应；市场型环境规制对工业绿色化的影响存在部分中介效应，可通过技术创新"挤出效应"抑制工业绿色化；公众型环境规制与工业绿色化关系只有中介效应，且公众型环境规制通过技术创新"激励效应"促进工业绿色化；异质性环境规制驱动工业绿色化的技术创新中介效应的研究结论经稳健性检验依然不变。研究认为：在推进异质性环境规制驱动工业绿色化过程中，应充分利用公众型环境规制驱动技术创新"激励效应"，同时应有效规避市场型环境规制驱动技术创新"挤出效应"。

Measuring systemic risk-adjusted liquidity (SRL)—A model approach

Little progress has been made so far in addressing—in a comprehensive way—the negative externalities caused by excessive maturity transformation and the implications for effective liquidity regulation of banks. The SRL model combines option pricing theory with market information and balance sheet data to generate probabilistic measure of systemic liquidity risk. It enhances price-based liquidity regulation by linking a bank’s maturity mismatch impacting the stability of its funding with those characteristics of other banks, subject to individual changes in risk profiles and common changes in market conditions impacting funding and market liquidity risk. This approach can then be used (i) to quantify an individual institution’s time-varying contribution to expected losses from system-wide liquidity shortfalls and (ii) to price insurance premia that provide incentives for banks to internalize the social cost of their individual funding decisions.     

The impact of the French Tobin tax

We analyze the impact of the introduction of the French Tobin tax on the turnover and measures of the liquidity and volatility of the affected stocks with nonparametric tests on individual stocks, difference-in-difference tests and other robustness checks controlling for simultaneous month-of-the-year and size effects. Our findings indicate that the tax produces a significant reduction in turnover and volatility (measured in terms of stock price volatility and the high–low price range) and inconclusive effects on liquidity when the latter is evaluated under the two dimensions of the estimated bid–ask spread and the Amihud (2002) price impact ratio.
