控制权收益与超控制权收益：大股东补偿与侵占

大股东获取控制权需要付出相应的成本,这些成本应该得到补偿,在公司治理实践中大股东有获得这种回报即控制权收益的正当要求。同时,由于大股东的控制优势,他们可能会利用公司治理、法律机制等不完善的治理环境侵害其他投资者的利益而获得超控制权收益。本文计量了这两种收益,修正了既有文献所认为的控制权私人收益就是大股东侵害的观点,对大股东公司治理机制提出建议。     

聚集外部性的非对称性承受与人口过度集中

由于农民工工资与城市生活成本的非相关性、农民工和应届大学毕业生对城市病的不敏感性、以及大城市居民中劳动人口数量很大的迁移成本等问题的存在,大城市工人部分丧失了向厂商索取较高名义工资以补偿其较高生活成本的能力。此时,厂商享受着大城市较高的聚集经济带来的高效率,却不用对工人较高生活成本进行完全补偿。这种厂商和工人承受聚集外部性的非对称性,必然引发生产与人口在大城市过度集中问题。     

我国上市公司增发的市场效应研究

通过研究2000-2004年沪深股市实施增发的86家A股上市公司在增发公告日、上市日的表现,发现公告日、上市日的平均超额收益率均为显著的负数,且上市日的负价格效应要大于公告日。老股东优先配售比例和再发行价格/前价格均对原流通股股东发生作用,而增发价格除以每股净资产和资产负债率则更多地对新流通股股东发生作用,由此印证了最初的假设：公告日股票价格波动的行为主体是原来的流通股老股东,上市日股票价格的波动主要是受新流通股股东的影响。     

上市公司增长机会、增发数量与股价反应

以2007年至2009年成功增发的A股上市公司为样本,对我国上市公司增发数量与股价变动的相互关系进行研究,结果表明:上市公司的增发数量内生于其增长机会,增长机会越大的公司增发数量占发行前总股本的比率也越高;股市对上市公司的过度增发会做出显著的负面反应,但仅有微弱的证据表明谨慎增发会导致股价下跌;公开增发的上市公司较之于定向增发的上市公司具有更多的过度增发倾向,且股价反应也更剧烈。     

创业板IPO超募现象解析——以创业板上市的前100家公司为例

创业板市场上普遍存在的超募现象及其所带来的危害引发了全社会的广泛关注和担忧。以创业板上市的前100家上市公司为例,巨额的超募资金主要用于投资并购、还贷补充流动资金、买房置地和存放银行。通过深入分析后发现,超募的原因主要来自创业板市场机制的不完善、发行人的利益驱动、保荐机构的管理缺位和投资者的盲目跟风这四个方面,应从完善发行定价机制、加大市场监管力度和加强投资者教育入手,寻求治理超募现象的对策。     

闽台农业合作食品安全存在问题及其影响

本文通过对闽台两地的农产品存在的化学物质残留超标问题进行研究,尤其是福建食品化学物质残留超标问题更为严重。食品安全问题在一定程度上阻碍了闽台农业合作的深化发展。     

International capital flows,debt overhang and volatility

This paper shows how international capital flows originate boom‐bust and sunspot episodes in a neoclassical growth model of a small, open economy. A limit is imposed on how much the economy can borrow from foreign creditors and it is made endogenous by assuming that the debt‐to‐GDP ratio is procyclical. The steady state is locally indeterminate when the credit multiplier is larger than some threshold level, whereas saddle‐point stability prevails when the credit multiplier is low enough. As a consequence, high levels of the credit multiplier lead to both booms followed by busts and sunspot‐driven volatility near the steady state, while, in contrast, low levels ensure monotonic convergence. Compared with saddle‐path equilibria, boom‐bust and sunspot equilibria are associated with both lower welfare and debt overhang, that is, a crowding‐out effect of credit: when the economy is highly leveraged, it uses savings to cut down foreign debt, at the expense of both human and physical investment. Numerical examples show that indeterminacy arises for debt‐to‐GDP ratios that fall within the range of available estimates. Finally, the effects of shocks to the world interest rate on output and consumption are amplified and persistent in the debt overhang regime.     

过度信息市场环境下品牌战略的建构

本文认为,目前市场正从信息短缺时代的"信息发现"困难转向信息过剩时代的"信息识别"困难,信息过度与市场信息短缺一样都存在着信息不对称问题,且具有更多的风险,它使企业产品信息与顾客识别之间存在更复杂的冲突。文章提出,品牌在过度信息市场环境下对信息不对称性有弱化作用,在品牌战略建构过程中应力求形成和培育品牌生态系统(基于信用而形成的社会关系网络)效应。     

Bundling governance mechanisms to efficiently organize small firm loans

Bank loans are a common source of financing for small firms. While scholars have examined specific conditions that affect small firm loan approval and interest rates, practical questions remain about how these loans are structured to address characteristically acute challenges from asymmetric information. This paper suggests collateral, reputation, and relationship banking each perform unique exchange-organizing tasks, and that small firms systematically use them in predictable combinations. A multiple discriminant analysis of 796 small firm loans suggests four governance bundles are commonly employed in this setting. The implications for managers focus on how loan governance mechanisms are most efficiently bundled together.     

My Reflections on the FPC's Strategy

I review the workings of the United Kingdom's Financial Policy Committee to illustrate the challenges of implementing macroprudential policy. I describe the committee's remit, explain my views on the channels of financial instability that the committee tries to mitigate, describe the tools the committee has its disposal and outline the principles it uses in deploying these tools. I conclude by offering some of the lessons I have learned in serving on the committee and highlighting a few challenges for macroprudential policymakers.
