Is regulatory adoption ceremonial? Evidence from lead director appointments

Research Summary: Regulatory bodies often wrestle with the thorny question of whether to mandate a governance practice or allow for organic adoption. While mandates afford rapid diffusion, we theorize that they also result in ceremonial adoptions. Leveraging a quasi‐natural experiment, we compare adoption outcomes for a governance practice—lead director adoption—that was mandated by the NYSE but not the NASDAQ. We find that NYSE firms are more likely than NASDAQ firms to have installed a lead director as a symbolic management tactic, so their lead directors are less effectual. We also find that transient institutional investors are deceived by this symbolic management, but dedicated institutional investors are not. Managerial Summary: Shareholders and analysts often desire to see companies introduce strict governance measures, such as proxy access and independent boards. Consequently, regulatory bodies often wrestle with the thorny issue of whether and when to mandate such practices for all companies. What they might not realize is that mandates may not work as well as they seem. Although more companies adopt reform under a mandate, they do so merely as a symbolic gesture. We look at one governance reform—appointing a lead director—finding that companies who introduce this reform as a result of a mandate appoint someone that is relatively toothless. We also find, though, that savvy investors are not actually fooled by this tactic and will trade out of firms that attempt such symbolic management.     

用于牛粪固液分离的变导程螺杆挤压脱水机的结构设计

通过对变导程螺杆挤压脱水机在畜牧养殖农场的实验表明,本文设计和制造的变导程螺杆挤压脱水机能够对牛粪进行合适的分离,而且分离出的牛粪干燥物干燥度合适,分离出的液体中的固体悬浮物少。因此,本文对用于牛粪固液分离的变导程螺杆挤压脱水机的总体设计的研究有一定的实用价值。

浅析任务引领教学方法中任务的设计

在职业院校的课程教学方法改革中,任务引领式教学法是较好实现工学结合的一种方法,绝大部分教师都想应用这种方法进行教学,培养更多满足社会需求的高素质技能型人才,但在如何设计教学任务、教学任务的类型有哪些、教学任务从何处来等问题,不少教师心中无底。     

价值多样性和社会主义核心价值观

党的十七大报告关于建设社会主义核心价值体系的论述,为引领价值多样性指明了方向。现阶段,我国社会客观存在的各种思想和价值观念相互交织、激荡和碰撞,彼消此长,呈现出"一元主导,多样并存"的趋势,价值多样性在很大程度上猛烈地冲击着社会主义核心价值体系的建设。因此,用社会主义核心价值观引领多样性的人生价值观,对大学生思想建设具有重大的现实指导意义。     

Information search behavior of Hong Kong's inbound travelers‐a comparison of business and leisure travelers

Abstract

The purpose of this study is to examine the information search behavior of Hong Kong's inbound tourists, in particular business and leisure travelers. The study clearly shows that business and leisure travelers demonstrate different information search behavior. ‘Personal experience,’ ‘Travel agency/tour company,’ ‘Airlines’ and the ‘Internet’ are most frequently relied upon by business travelers in searching for travel information, while leisure travelers prefer ‘Travel agency/tour company,’ ‘Friends or relatives,’ ‘Travel guide books,’ and ‘Personal experience.’ The study also reveals that the total number of information sources used and the length of pre‐trip planning lead‐time are significantly different between these two groups of travelers. First time travelers also have a longer pre‐trip planning lead‐time than repeat travelers. Furthermore, business and leisure travelers perceive the levels of influence of several information sources, including ‘Corporate travel departments,’ ‘Friends or relatives,’ ‘Travel guide books,’ and the ‘Internet,’ differently. These information sources were classified into five different dimensions, including ‘Media,’ ‘Neutral,’ ‘Retail,’ ‘Interpersonal,’ and ‘Personal experience.’ Analysis based on travelers' purpose for traveling and demographic information was performed. Leisure travelers perceive the level of influence of ‘Neutral’ sources as significantly higher, and those with lower household incomes perceived the level of influence of ‘Personal experience’ as lower. The results of this study will allow marketers in Hong Kong to better understand travelers’ information search behavior so that they can more effectively tailor their marketing strategies to these two major markets.     

The Role of U.S. Market on International Risk‐Return Tradeoff Relations

We study the intertemporal risk‐return tradeoff relations based on returns from 18 international markets. We find striking new empirical evidence that the inclusion of U.S. market returns significantly changes the estimated risk‐return tradeoff relations in international markets from mostly negative to predominantly positive. Our results are consistent with the lead‐lag effect between U.S. and international markets in the sense of Rapach, Strauss and Zhou.
