进口安全视角下中国棉花进口波动研究

论文针对进口安全问题,利用1992-2012年时间序列数据,以中国棉花进口为研究对象,运用进口市场集中度、进口依存度、自给率、贸易竞争力等方法从控制力和竞争力角度对中国棉花进口安全程度进行研究.分析得出:中国棉花供求矛盾突出;棉花进口维持在较高水平;棉花进口集中度较高;中国棉花进口依存度逐步由“不安全”状态向“危机”状态转变;中国棉花的自给率一直处于“危机”状态;中国棉花贸易竞争力也较弱,棉花安全也处于“危机”状态.     

Analysts' Forecasts Following Forced CEO Changes

This paper examines analysts' earnings forecasts during the period of uncertainty following a change of chief executive officer (CEO). It distinguishes between forced and non‐forced CEO changes, and examines whether analysts utilize their information advantage to reduce the heightened uncertainty of a forced change of CEO. Examining a sample of Australian companies followed by analysts between 1999 and 2009, we find that forecasting accuracy is lower and earnings forecasts are more optimistic for firms experiencing forced CEO turnover compared to firms not undergoing such a change. However, dispersion is not statistically different. The results suggest that forced CEO turnover events provide a challenge to the forecasting environment for analysts. During CEO changes, investors should be aware that forecasts are less accurate and have an optimistic bias.     

Auditors' Fee Premiums and Low‐Quality Internal Controls*

We examine the relation between low‐quality internal controls and audit fee premiums. Using a novel data set of audit hours and audit fees we find, consistent with the audit risk model, that auditors increase their effort (hours) owing to low internal control quality. We find that auditors also charge a significant fee premium to clients with internal control weaknesses. This premium is observed for severe internal control weaknesses and companies with low‐quality alternative governance mechanisms. The results are robust to multiple methods to address endogeneity, including company fixed effects, difference‐in‐differences design, and a propensity score‐matched sample. Taken as a whole, low internal control quality leads to fee premiums, which are a deadweight loss to client companies.     

财政分权、经济发展与城乡居民收入差距——基于省级面板数据的实证分析

本文基于2002—2011年省级面板经济数据,运用联立方程组模型分析财政分权对城乡居民收入差距与经济发展的影响效应及二者之间的相互作用。研究发现,财政分权既有利于促进经济发展又能够缩小城乡居民收入差距,同时,不同地区的财政分权对经济发展和收入差距的影响效应因财政支出结构的不同而不同。此外,研究发现我国城乡居民收入差距与经济发展存在库兹涅茨倒U型曲线关系,并得出我国城乡居民收入差距并没有达到拐点。     

Foreign direct investment in Mexico Determinants and its effect on income inequality

By conducting panel data analysis across 32 federal entities in Mexico over the period 1994-2006, this paper studies the determinants of foreign direct investment (FDI) and its effect on income inequality within and between regions. We observe that the level of development and the size of the market have a direct relationship with FDI and therefore, they tend to increase the inequality gap between regions, but there is no evidence suggesting that it creates inequality within them.     

Explaining employee turnover in an Asian context

Employee turnover is giving sleepless nights to HR managers in many countries in Asia. A widely‐held belief in these countries is that employees have developed ‘bad’ attitudes due to the labour shortage. Employees are believed to job‐hop for no reason, or even for fun. Unfortunately, despite employee turnover being such a serious problem in Asia, there is a dearth of studies investigating it; in particular studies using a comprehensive set of variables are rare. This study examines three sets of antecedents of turnover intention in companies in Singapore: demographic, controllable and uncontrollable. Singapore companies provide an appropriate setting as their turnover rates are among the highest in Asia. Findings of the study suggest that organisational commitment, procedural justice and a job‐hopping attitude were three main factors associated with turnover intention in Singapore companies.

The Effectiveness of Two Online Persuasion Claims: Limited Product Availability and Product Popularity

Two experiments were conducted to evaluate the effectiveness of two online persuasion claims: limited product availability (e.g., only 3 items left) and product popularity (e.g., 94% of consumers bought this product after viewing this site). The popularity claim appeared to enhance quality perception, particularly among highly risk-averse consumers, and purchase intention. We attribute these findings to the quality signaling effect and the bandwagon effect of the claim. On the other hand, the limited availability claim exerted no influence: low message credibility and the lack of psychological reactance are deemed to be possible reasons for the insignificant effect of the claim.
