区域电力市场的十大障碍及其对策 总被引:1,自引:0,他引:1
中国迄今已经在电力改革方面取得了很大进展.目前所处的行业重组阶段,旨在为建立竞争性电力市场奠定必要的基础.尽管最初的省级电力市场试点为提高行业的经济和技术水平创造了条件,但建立区域电力市场以优化资源配置和提高效率的潜力显然更大.但是,建立区域电力市场的难度远大于建立省级电力市场.本文讨论在中国建立区域电力市场的障碍因素及其可以采取的应对措施. 相似文献

Hedging in the Possible Presence of Unspanned Stochastic Volatility: Evidence from Swaption Markets 总被引:2,自引:0,他引:2
This paper examines whether higher order multifactor models, with state variables linked solely to underlying LIBOR‐swap rates, are by themselves capable of explaining and hedging interest rate derivatives, or whether models explicitly exhibiting features such as unspanned stochastic volatility are necessary. Our research shows that swaptions and even swaption straddles can be well hedged with LIBOR bonds alone. We examine the potential benefits of looking outside the LIBOR market for factors that might impact swaption prices without impacting swap rates, and find them to be minor, indicating that the swaption market is well integrated with the LIBOR‐swap market. 相似文献

The development of efficient and competent staff in accounting firms is enhanced by the use of formal performance evaluation systems. This paper reports on a study which examined the objectives and uses of performance evaluation, the methods used, the dimensions evaluated, the development of overall assessments, the provision of feedback and the perceived strengths and weaknesses of the systems in use. In general, the performance evaluation process in these firms is effective, but there is scope for improvement in a number of areas. 相似文献

The last thirty years have witnessed the appearance and rapid expansion of Islamic banking both inside and outside the Islamic world. Islamic banks provide financial products that do not violate Sharia , the Islamic law of human conduct. The Islamic principles upon which the banks claim to operate give an important role to social issues. Applying these principles, we develop a benchmark set of social disclosures appropriate to Islamic banks. These are then compared, using a disclosure index approach, the actual social disclosures contained in the annual reports of twenty-nine Islamic banks (located in sixteen countries) to this benchmark. In addition, content analysis is undertaken to measure the volume of social disclosures. Our analysis suggests that social reporting by Islamic banks falls significantly short of our expectations. The results of the analysis also suggest that banks required to pay the Islamic religious tax Zakah provide more social disclosures than banks not subject to Zakah . 相似文献

This paper examines the influence of bargaining power and property class on the prices of heterogeneous goods. Specifically,
it explores the impact of buyer and seller characteristics on the transaction prices of office properties. The empirical model
is based on the work of Harding, Rosenthal, and Sirmans (2003), which developed a method to distinguish between the impact of buyer and seller attributes on bargaining power and the choice
of otherwise unidentified price effects (i.e., property class) in the context of hedonic price models. The data set contains
information on transaction prices of office properties in Cook, DuPage, and Lake Counties, Illinois from 1995 to 1997. The
results reveal systematic differences in bargaining power and property class for certain groups of buyers and sellers contained
within the sample. 相似文献

A study of Queensland public-sector entities suggests outsourcing of internal audit services to be extensive (88%), with 51% of respondent agencies adopting co-sourcing and 37% of the agencies fully outsourcing. Results suggest that internal audit outsourcing is largely adopted for non-financial reasons such as lack of technological know-how and service quality rather than financial reasons. Deficiencies of current governance arrangements concerning internal audit outsourcing include (1) a lack of audit committee involvement in outsourcing processes, particularly in co-sourcing entities, and (2) inadequate segregation of duties whereby the same senior management is involved in key arrangements including selection, approval, negotiation and evaluation of contractual performance. 相似文献

In many new or repeat purchasing situations, business buyers must decide how many suppliers to consider (a “choice set”) in determining which supplier(s) to actually buy from or contract with. This paper develops an optimization approach to determining the size of the choice set, taking into consideration buyer utility and search and evaluation costs. A theoretical model is developed for both one-time and repeat purchase situations. The model is estimated using empirical data received from bids received for procurement auctions. In these auctions, suppliers provide bids for steel pipe based on two product attributes (price and delivery time). Model sensitivity to small changes in parameters is also tested. 相似文献

Using quarterly call report data from 2000 to 2016, we reexamine the relationship between net interest margins (NIM) and the yield curve for more than 5,500 U.S. commercial banks. In the full sample, yield curve and RGDP growth have positive effects on NIM, while inflation and deposit‐to‐loan ratios (D/L) have negative effects. Splitting the sample around the 2007–2009 crisis, we show the impact of yield curve and RGDP growth on NIM increasing during the “recovery” (2009Q3 to 2016Q4), and inflation and D/L changing signs. Positive effects of yield curve on profits vary with bank size and change over time. 相似文献
