城市狭窄场地深基坑联合支护技术应用研究

近年来,随着经济的发展社会的进步,城市建设规模逐渐加大,为了节约地上空间,节省土地资源,高层建筑、地下建筑、隧道等工程大幅度增加,充分利用地下空间的深基坑工程也随之增加。城市深基坑工程,施工场地狭窄,开挖较深,土方开挖难度大,施工运输困难。本文在对常用深基坑支护技术进行对比分析的基础上,结合工程实例,对混凝土灌注桩、喷射混凝土相结合的联合支护方式进行应用效果分析,目前,此类深基坑支护问题已经成为基坑支护的新课题,文章对城市狭窄环境下的深基坑支护技术施工优化提出对策建议。深基坑工程施工问题对整个建筑施工起着举足轻重的影响。     

Social responsibility in new ventures: profiting from a long‐term orientation

Socially responsible activities help create business value, develop strategic resources, and insure against risks, but also cost money and distract management. These prior findings are mainly based on established corporations and may not extend to new ventures in which the liability of newness may suppress some positive effects and amplify some negative impacts of socially responsible activities. New ventures whose strategic decisions have a long‐term orientation, however, are able to counteract their liability of newness and thereby generate net positive economic returns. We tested these relationships by surveying the chief executive officers and presidents and studying the signature Web sites of 149 new ventures. Copyright © 2012 John Wiley & Sons, Ltd.

信息、代理冲突与国有上市银行经理长期激励——基于银行经理企业家能力的分析

构建简单动态模型分析国有上市银行地区(部门)经理的长期激励机制设计问题.模型揭示了颇有意思的含义.企业家才能是银行长期发展的基本诱因.就绩效评估而言,EVA有利于经理做出即期最优投资决策,RAROC有利于银行长期发展.固定报酬合约将诱发地区经理的冒险行为,使贷款超过最优水平;随机支付合约或EVA状态依存支付合约将使总行实现最优贷款规模.EVA为零时,撤销机构、收回贷款权等,可减少当前风险,但使银行失去潜在投资机会.静态看,解雇经理未必获得预期效果;动态看,解雇威胁具有威慑作用,能迫使经理努力工作,增加股东价值.     

Market Underreaction to Free Cash Flows from IPOs

I examine the relation between initial public offering (IPO) long‐run stock performance and the amount of cash raised by the firm in the offering. I find that IPOs raising more cash have poorer long‐run performance. The result is robust to different measurement methods. The evidence suggests that the market underreacts to free cash flow related agency problems in IPOs. Consistent with this interpretation, I find that IPO long‐run performance is more sensitive to the new cash raised in the offering if an IPO firm has lower capital expenditure or higher opening bid‐ask spread.     

Decomposing the accrual premium: The evidence from two markets

We decompose the accrual premium and study its components in the debt and equity markets. We show that the importance of each accrual component depends on the sample and the type of market considered. The short‐term accruals component is primarily observed in equity markets, among small and young companies, which is consistent with mispricing arguments. The long‐term accruals premium is consistently positive and significant in different samples and markets. This component reflects growth in capital expenditures, and it is counter‐cyclical and predictable, which is in line with investment‐based explanations. Finally, the financial accruals component does not generate predictability.     

DYNAMIC TRADING VOLUME

We derive the process followed by trading volume, in a market with finite depth and constant investment opportunities, where a large investor, with a long horizon and constant relative risk aversion, trades a safe and a risky asset. Trading volume approximately follows a Gaussian, mean‐reverting diffusion, and increases with depth, volatility, and risk aversion. Unlike the frictionless theory, finite depth excludes leverage and short sales because such positions may not be solvent even with continuous trading.
