分权式改革为什么能成为经济持续快速发展的动力源泉呢?西方分权理论给出了解释。本文回顾了六个著名的分权理论:公共产品层次性理论、最佳职能配置分权论、俱乐部理论、最优分权论、分权误识理论和奥茨分权定律。     

Mozambique Metical Exchange Rate Dynamics: Evidence of Fractional Co‐Integration in the USA and South African Rates

This paper studies the exchange rate dynamics of the Mozambique metical with respect to the US dollar and the South African rand. However, instead of using standard I(0)/I(1) techniques, we use long memory and fractionally integrated and co‐integrated models. Our results indicate that the two exchange rates are highly persistent, with orders of integration equal to or above 1. They also seem to be co‐integrated, with an order of integration close to albeit above 0 but with an AR coefficient very close to 1. Thus, although the two series seem to be fractionally co‐integrated, shocks in the long‐run relationship between the two variables are persistent and take a long time to disappear.     

阿根廷债务重组：现实困局与制度反思

自2001年主权债务违约后,阿根廷经历了2005年和2010年两次债务互换,但是,由于少数“钉子户”债权人的反对并诉诸司法程序,阿根廷债务重组陷入再次违约的重大风险。回顾阿根廷债务重组的过程以及以对冲基金为主的少数债权人对阿根廷的诉讼,可以清晰地看出阿根廷主权债务重组困境是由阿根廷自身非审慎性的债务重组机制、美国行为的双重标准以及全球主权债务重组基础机制缺失等造成的。随着重债富国问题的出现,主权债务重组中的国内外司法管辖权、私人部门与公共部门参与、集体行动条款与同等权益条款,以及合同法与法定机制等争论更加凸显,建立一个全球性主权债务重组机制是国际金融体系稳定的基础任务。     

国际股票市场收益率和波动率的长记忆性研究

股票市场长记忆性问题是金融学研究的一个热点问题,对于市场有效性的研究和系统非线性结构的分析有着重要的意义。本文运用修正R/S分析和V/S分析两种方法对世界上28个国家(地区)的股票指数的日、周收益序列和日、周收益波动序列进行了完整的长记忆性研究。结果表明:对于收益序列,以美国为代表的大多数发达国家股市一般不存在长记忆性,而中国等发展中国家大多存在显著的长记忆性,尤其中国股市的长记忆性最强;对于收益波动序列,所有国家(地区)都具有长记忆性,并强于收益序列。     

Does Greater Amount of Information Always Bolster Attitudinal Resistance?

Previous research suggests that attitudinal resistance to information that challenges a prior evaluation increases with the amount of information underlying the prior evaluation. We revisit this proposition in a context in which a set of important claims about a target brand are presented either alone—a lower amount of isolated information—or along with other favorable, but less important claims—a higher amount of embedded information. Results from two experiments show that when the challenge occurs immediately after the initial evaluation, a greater amount of embedded initial information does produce greater attitudinal resistance. However, when the challenge occurs after a delay, a lesser amount of isolated information produces greater attitudinal resistance. The findings qualify previous assumptions about the role of prior information in attitudinal resistance, and support a constructive view of judgment revision and attitudinal resistance.     

Moral Memory: Why and How Moral Companies Manage Tradition

Recent research on the role of ethics in the organizational culture literature found practically the whole literature reduced to a debate between ethical rationalism and ethical relativism. The role of the past in the form of tradition to maintain and improve moral reflection is completely missing. To address this gap in the literature on the level of practice, the concepts of moral memory and moral tradition are applied to data on 22 companies that have long-standing moral practices. In this way, the practice of moral traditions can be explored with recent conceptual advances and a list of best practices delineated. Moral memory is the recollection of and attachment to the succession of past events and experiences that maintains moral tradition. Moral tradition is the continuing transmission and reception of related moral themes through multiple generations of employees. It is found that companies that maintain moral traditions tend to develop “family” cultures with considerable compassion for workers as persons who have non-economic needs and rights. These companies also temper the role of leadership, insisting that leaders are responsible for and are evaluated by the company’s moral traditions. Finally, moral traditions are essential mechanisms through which companies paradoxically both stimulate and limit competitive behavior. Steven P. Feldman is Associate Professor of Management Policy, Weatherhead School of Management, Case Western Reserve University. Over the last decade, Dr. Feldman’s research has explored the role of moral memory and moral tradition in the ethical aspects of organizations. His book, Memory as a Moral Decision: The Role of Ethics in Organizational Culture (2002), found that the emotional and cognitive aspects of memory to be key in establishing moral organizational cultures. The moral importance of the past in the present has received little attention in the literature on organizational culture. Winner of the Distinguished Lectureship in Business Ethics from the American Fulbright Program, Dr.␣Feldman will be carrying out research on ethical issues in American-Chinese business relations in Shanghai in 2007.     

Analyzing the Memory Impact of Advertising Fragments

Marketers are making increasing use of very brief messages that mention just a brand name or a brand name with a short headline, as in event sponsorship and program endorsements. There has been debate over the effectiveness of these advertising fragments. This paper introduces an approach for controlled testing of the effects of advertising fragments. Using a reaction-time based procedure, we show that a key effect of advertising fragments is to revive established brand associations, even though these associations are not explicitly communicated. This reactivation occurs not only when these names receive focal attention, but also when they receive nonfocal attention.     

二元经济结构转换与发展农村集体经济

刘易斯在吸收了马克思和古典经济学家关于劳动力和经济增长理论的基础上,指出新古典增长模型忽视了部分发展中国家劳动力无限供给这一特征,认为工业化的发展能带动农业的现代化。但是中国目前大量的剩余劳动力的存在,城乡差距的拉大,使人们意识到由于我国特殊的国情和“增长极”的作用,解决农村问题的关键是要依靠自身的发展,发展集体经济,提高农村劳动生产率,促进工农业均衡发展,建设社会主义新农村。
