Multinationals,Information Update,and Product Adaptation *

This paper develops a dynamic model of decision making by multinational firms. The firm chooses between exporting and producing abroad when it expands the market. Bayes learning is incorporated into this model in addition to fixed cost and transport cost Production in a foreign country gives the firm new information about the demand function. This information is applied to adjust the firm's expectation as well as output choice in the future. This process not only reduces the risk encountered by a firm in a foreign market, but also increases acceptance of the product which the firm manufactures. This paper concludes even if producing abroad loses money in the first period, the firm may still choose to set up plants in foreign countries rather than exporting, due to the dynamic information advantage associated with going multinational.

香港“轨道交通＋土地综合利用”模式的启示

香港＂轨道交通＋土地综合利用＂的模式是一种集地铁投资、建设、运营和沿线土地综合开发于一体的综合开发模式,是由港铁统筹开发的。从运作流程上分为项目谋划、项目明确、项目开发和项目运营四个阶段,在营造高效率的公共交通体系、促进土地高度集约、节约利用等方面都取得了明显效益。对我国城镇交通发展有五点启示和借鉴：（1）交通规划与土地规划同步进行、有机结合;（2）推进经营性土地有偿使用;（3）运用节地技术和模式,充分发挥土地的复合利用功能;（4）分层出让,实现土地利用的多元化价值;（5）拓展融资渠道,实现轨道交通多渠道投融资。     

两类信贷腐败比较研究:审批腐败与支付腐败

企业在向银行寻求信贷融资时遇到的信贷腐败可分为两类：金融机构中主管信贷审批的高层人员的审批腐败;负责信贷发放的基层人员的支付腐败。通过分析两种类型的腐败在项目寻求信贷融资时的影响,揭示信贷腐败与信贷融资之间的关系,指出两类腐败具有相互影响的关系,基层支付腐败对信贷融资项目产生逆向选择,阻止了低风险项目的信贷融资行为,而高层人员倾向于和融资项目合作,因而具有减少基层机构支付腐败的动机。     

冷链物流设施投入博弈分析

研究了非合作条件(包括第三方物流服务商主导、双方对等)与合作条件下供应商与物流服务商设施投入的博弈问题.研究表明,纳什均衡时,第三方物流服务商不会分摊供应商的设施投入;物流服务商主导条件下,第三方物流服务商的利润比纳什均衡时大,而供应商在何种博弈时的利润更大则取决于具体的参数.供应商在合作博弈时的最优设施投入水平最高,而第三方物流服务商在何种博弈中的最优设施投入水平最高则取决于具体的参数.     

机构投资者持股特征对IPOs长期绩效影响的实证研究

文章从机构投资者持股规模、持股集中度、持股稳定性三个方面归纳不同类型机构投资者持股特征,采用Log-it回归检验机构投资者持股特征对上市后股票购买并持有异常回报率(BHAR),即IPOs长期绩效的影响。实证结果验证了机构投资者持股比例越高、持股稳定性越强,股票上市后的长期绩效越好;而持股比例低、持股集中度高、持股稳定性差的机构投资者也导致了股票长期表现较差。积极型机构投资者对股票长期绩效具有正面的影响。因此,引入积极型机构投资者符合当前我国股票市场深化改革的目标。     

现代物流与产业结构升级关联机制研究

运用协整检验方法,定量分析现代物流与产业结构升级之间的关系,研究结果发现,现代物流与产业结构升级之间存在长期稳定的均衡关系,产业结构升级率每提高1个百分点,物流贡献率增加0.140 018 7个百分点;并进一步利用灰色关联分析理论对现代物流贡献率与第二产业结构升级率和第三产业结构升级率的关联度进行测算,结果发现第二产业结构升级率与物流贡献率的关联度更高,这说明第二产业结构升级对我国现代物流业的发展具有较大的影响.     

Uniform pricing effect: The influence of uniform pricing on product value judgement and purchase intention

Uniform pricing, which is a pricing strategy that sets a unified price for all products in the store or all products in the same category, is becoming increasingly popular over the past decades. However, scarce attention has been paid to investigating its impact on consumer behaviour. This research investigates the influence of uniform pricing on product value judgements and purchase intentions. Four studies demonstrate that uniform pricing (vs. non-uniform pricing) could induce stronger promotion perception, which leads to more positive product value judgements and purchase intentions. Moreover, price sensitivity and product involvement moderate this effect, and this effect only exists for high price-sensitive consumers and low product involvement consumers.     

Financial Reporting and Employee Job Search

We investigate the effects of financial reporting on current employee job search, that is, whether firms' public financial reports cause their employees to reevaluate their jobs and consider leaving. We develop theory for why current employees use earnings announcements (EAs) to inform job search decisions, and empirically investigate job search based on employees' activity on a popular job market website. We find that job search by current employees increases significantly during EA weeks, especially when employees are more mobile and when their information frictions are greater. We also find that employees use EAs to update their expectations about their employers' economic prospects, consistent with learning, and some evidence that positive announcements elicit less search. Our paper contributes to the burgeoning labor and accounting literature by providing among the first evidence closely linking financial reports to employee learning and job search.
