政府调控强化与股市平准基金的设立

2004年至今中国股票市场出现非理性的剧烈波动，原因之一就是政府调控股市的低效率。在建设市场经济过程中，政府适当的干预是维护股票市场正常发展的必要条件，而股市平准基金作为一种有效的政府宏观调控工具，将对我国股票市场的健康发展发挥作用。

The relationship between major-league sports’ official sponsorship announcements and the stock prices of sponsoring firms

This study presents analysis of the impact of “official product” sports sponsorships with the National Football League (NFL), Major League Baseball (MLB), the National Hockey League (NHL), the National Basketball Association (NBA), and the Professional Golfers Association (PGA) on the stock prices of sponsoring firms. The primary finding of the study is that, in the main, announcements were accompanied by increases in shareholder wealth. The 53 sponsors analyzed experienced mean increases in stock valuations of about $257 million. A multiple regression analysis of firm-specific stock price changes and selected corporate and sponsorship attributes indicates that official product sponsorships with the NBA, NHL, and PGA and those with smaller market shares were associated with the largest gains in share prices. Although corporate cashflow (a proxy for agency conflicts) is statistically unrelated to shareholder approval, sponsorships by high-technology companies were associated with stronger stock price reactions than otherwise. Finally, product congruence with the sponsored sport was positively related to changes in stock prices. T.

关于提高印花税税率的冷思考

印花税税率调高会带来交易费用的上升,可以抑制短期投机,从而在一定程度上稳定市场。但在我国证券税制不完善的情况下,股票交易的印花税存在缺乏法律依据、税种错位、职能错位、征收范围错位等问题,其身兼数职,扮演了多税种合一的角色,仅靠调整印花税难以真正达到压缩股市泡沫、促进资本市场健康发展的效果,还会带来印花税其他职能的丧失。因此,开征差异性证券交易税,对印花税进一步改革已迫在眉睫。     

流动性过剩、中长期贷款与银行稳定性

近年来,我国商业银行出现了流动性过剩现象,在这样的背景下,商业银行依靠提高中长期贷款来获得超额收益,但是中长期贷款增加可能导致固定资产投资过热.调整存款准备金率可以直接影响新增短期贷款的规模,但对新增中长期贷款规模不能产生明显的影响.同时,流动性过剩导致了中长期贷款规模的快速增长,可能降低银行稳定性.

论LLSV法律来源论的缺陷性

拉普特等人用数据来表明,法律来源于普通法系国家比法律来源于大陆法系国家特别是法国大陆法系国家能更好地保护投资者,而德国大陆法系国家和斯堪的纳维亚国家则介于这二者之间。公司所有权的集中程度在他们的研究中被认为是对投资者保护差的一种适应性反映。在本文,我们用中国和其他国家的证据来说明政治经济因素比法律来源论能更好地解释在中国的转型经济中对小股东保护差的原因。我们认为中国上市公司所有权非常集中的原因是政府决策的直接结果,也认为政府控制绝大部分上市公司在某种程度上减弱了对小股东的保护。
