多元化战略、经济绩效与资本结构——关于上市公司股权融资偏好解释

我国上市公司存在十分强烈的股权融资偏好,学术界一般将其原因归结为股权融资成本偏低。笔者研究则表明,融资成本因素并不能全部解释上市公司股权融资偏好。本文从企业多元化经营战略角度来剖析股权融资偏好。研究发现:企业多元化程度越低负债率越低,企业经济绩效越好;企业有动力降低负债率,采用股权融资。研究还发现,企业多元化战略已经构成融资决策的有效约束,股权融资偏好是上市公司的理性选择。

The hydroelectricity consumption and economic growth in Asian countries - evidence using an asymmetric cointegration approach

ABSTRACT

This study examines the four commonly tested hypotheses in hydroelectricity consumption – economic growth literature for 12 Asian countries. Our results from a recently developed hidden cointegration technique uncover rich and significant relationships between negative and positive components of the variables under consideration. In particular, we find evidence to support the neutrality hypothesis in five countries (Bangladesh, Indonesia, Pakistan, Philippines, and Thailand), the growth hypothesis in four countries (India, Japan, South Korea and Taiwan), and both growth and conservation hypotheses in three countries (China, Malaysia, and New Zealand). These findings suggest that appropriate economic policies should be elaborated on the basis of the country’s specific hydroelectricity consumption–growth nexus. Finally, our new evidence suggests that the lack of stable relationship between hydroelectricity consumption and economic growth documented in previous studies for some of these countries could be due to the failure to properly account for the nonlinearity property in the data.     

A note on the effect of rate-of-return regulation under uncertainty

This paper corrects the errors of Peles and Stein's capital-setting (i.e., capital is ex-ante) model and Das' quantity-setting (i.e., all inputs are ex-ante) model. It also shows that rate-of-return regulated firms always overcapitalize in the quantity-setting case, but may overcapitalize, undercapitalize or produce efficiently in the capital-setting case.

日本银行业化解不良资产的经验及启示

上世纪90年代以来,受泡沫经济崩溃影响,日本银行业不良资产问题日益突出.在此后十余年间,日本政府不断完善不良资产处置法规和机制建设,建立破产金融机构处理框架,动用公共资金救助银行机构并对企业进行重组援助,直至2005年不良资产治理成效显现.得益于此间建立起完善的金融监管体系和风险处置机制,日本银行业不仅抵御了2008年国际金融危机的冲击并长期保持了较低的不良贷款率.考察日本银行业不良资产的成因、表现及解决方法,借鉴其经验教训,对于我国化解银行不良资产具有重要的现实意义.     

从对冲套利看可转债资产替换

在缺乏卖空机制的环境下，可转债相对价值的实现将主要来源于转债与股票之间的资产替换。尤其是在杠杆放大的资产替代策略下，可转债投资的盈利模式将出现根本性变化，股票价格的波动成为影响策略应用效果的最重要因素。本从对冲套利的角度，通过对等额和杠杆放大资产替换策略的模拟与分析，就资产替换策略的应用环境、杠杆选择与实证效果等问题进行了较为详尽的研究。     

Regulation and investment behaviour in the telecommunications sector: policies and patterns in US and Europe

This paper reports the results of the quantitative analysis of international experience of the relationship between infrastructure investment in the deployment of capacity that can carry large volumes of voice and data traffic and regulatory policy changes in the telecommunications sectors. It looks at the relationship between infrastructure investment for these infrastructure assets and the access pricing régimes for local exchange carriers in the United States and Europe. It then looks at the relationship between various aspects of regulatory and institutional policy changes in Europe and how they affect access prices.The paper finds that a lower access price promotes greater deployment of digital technology among US incumbent local exchange carriers (ILECs). Based on this finding, it suggests that it is in the ILECs interest to have access to their networks encouraged.The European data for interconnection are recent and far reaching conclusions are not feasible, but the findings, however, suggest that competition has worked by facilitating new entry through decreasing interconnection prices, although path dependencies, of existing and traditional concepts, in the mindsets of operators as well as regulators, may account for these findings.
