经济条件、人口特征和风险偏好与城市家庭的旅游消费——基于国内24个城市的家庭调查

旅游者的旅游消费支出对旅游产业的发展至关重要。它是旅游者的经济条件、人口特征和行为特征等因素共同作用的结果。但国内现有的研究由于多采用宏观数据,缺少描述旅游者人口和行为特征的微观数据,对旅游消费支出的影响因素分析有失偏颇。文章采用2010年对中国24个城市的居民家庭进行调查收集到的旅游消费数据,综合考虑家庭的经济条件、人口特征和行为特征,以家庭为单位,采用广义线性模型定量研究了影响家庭旅游消费支出的影响因素。研究表明:除家庭资产和收入外,家庭对收入的预期显著影响家庭的旅游消费,这解释了旅游产业对宏观经济的变动比较敏感的原因。它折射的宏观经济意义是显而易见的:当经济不景气时,旅游业可能是率先遭受冲击的产业。反之,当经济向好发展时,旅游业也往往蒸蒸日上。以户主年龄作为代理变量,调查还发现城市家庭的旅游消费与家庭生命周期密切相关,当户主年龄在25~34岁时家庭旅游消费支出达到高峰。此外家庭的风险偏好也显著影响家庭的旅游消费支出。借鉴美国消费金融调查用分类变量测度风险厌恶的方法,文章发现风险厌恶程度越高的家庭越愿意将大部分收入用于储蓄,从而相应地减少旅游消费支出。由于家庭承受的风险多数无法对冲,因此提高风险厌恶程度较高的家庭的旅游消费,恐怕单靠旅游产业自身还无法解决,需要保险业等相关产业共同努力来创造一个较好的旅游产业发展环境。     

Build Coalitions to Fit: Autonomy Expectations,Competence Mobilization,and Job Crafting

Job crafting offers several beneficial organizational outcomes, yet little is known about what makes employees engage in it. In particular, the role of leaders in influencing their subordinates to engage in job crafting has been insufficiently studied. Drawing on role theory, we suggest that the congruence of leader‐subordinate autonomy expectations nurtures subordinates’ experiences of having their competences adequately utilized in their jobs. This experience, which involves the competence mobilization of their work roles, subsequently fosters subordinates’ engagement in job‐crafting behavior. A two‐stage field study of 145 leader‐subordinate dyads using cross‐level polynomial regression and response surface analysis supported the (in)congruence hypotheses. The results also demonstrated that subordinates’ perceived competence mobilization mediates the relationship between autonomy expectation (in)congruence and job crafting. In addition, leader coalition as a moderator strengthens the effect of perceived competence mobilization as a psychological condition for job crafting. Implications for practice and future research are discussed. © 2016 Wiley Periodicals, Inc.

Retail career attractiveness to college students: Connecting individual characteristics to the trade-off of job attributes

This study examines how U.S. business college students evaluate the attractiveness of potential job opportunities by making trade-offs among important job attributes. Using a conjoint approach, we examine the relative importance of industry type, starting salary, five-year salary, training, benefits, and work-life balance in job choice decisions. We also examine the effects of job applicants' career expectations and core competencies on their job choice determinants. An analysis of 162 business students' evaluations of 27 job profiles indicates that five-year-salary outweighs all other attributes. Their career expectations and core competencies have a substantial influence on their ensuing job choice. We suggest recruitment strategies to target recent college graduates with consideration of individuals' different career expectations and core competencies.     

The house price determination process: Rational expectations with a spatial context

Applying the rational expectations hypothesis, this essay models the current value of a house as the conditional expectation of the discounted stream of housing services accruing to the owner of the house. The value of housing services is determined by neighborhood effects as well as the physical attributes of the property itself. In the existing hedonic literature, future transactions have not been utilized to describe neighborhood effects. The rational expectations asset pricing model in this study accounts for expected future neighborhood effects as well as observed current neighborhood effects. The reduced form of the rational expectations model is a spatial autoregressive (SAR) model with two spatial lags. After employing the generalized method of moments (GMM) in estimating the spatial asset pricing model, I find that both expected future transactions and prior transactions in the neighborhood are significant. The inclusion of expected future transaction prices in the neighborhood takes into account the influence of expected changes in the community and factors these potential changes into the current house price. This is consistent with forward-looking households. The forward-looking model generates superior out-of-sample prediction performance relative to both the conventional hedonic model without considering neighborhood effects or the standard spatial hedonic model including only past transactions.     

投资者的异质预期对IPO抑价的影响

针对IPO抑价中的有意抑价和无意抑价问题,运用行为金融理论,在以机构投资者利益最大化推导出机构投资者需求函数的基础上,研究了散户和机构投资者的同质和异质预期对IPO抑价的影响,并进行抑价进行比较分析。研究表明:机构投资者具有有意抑价的激励;当机构投资者与散户对新股价值不存在分歧时,IPO抑价中只有有意抑价,而无无意抑价;当机构投资者与散户对新股价值存在分歧时,分歧越大,IPO抑价越高,而抑价中的有意抑价不变、无意抑价增大。     

对推进城乡公共服务均等化问题的初步思考

《中华人民共和国国民经济和社会发展第十二个五年规划纲要》中强调要＂推进基本公共服务均等化＂。近年来,随着我国国民经济的不断发展,农村公共服务体系也逐步改善。但总体上农村的基本公共服务并不完善,仍然较为落后。积极推进城乡基本公共服务均等化,关键在于积极构建相关制度基础和实现机制,必须不断创新农村社会建设载体,让农民在教育、就业、医疗等方面与城里人一样享有改革发展的成果。     

汇率变动与贸易余额——基于政策干预和预期因素的模型分析和实证研究

文章重点讨论了政策干预下的汇率走势,以及预期因素作用下进口商和消费者的行为模式,在假定马歇尔—勒纳条件成立,汇率变动完全传递给贸易品价格的条件下,研究了汇率变动和贸易余额的关系。认为在政策干预和汇率走势形成稳定预期的条件下,汇率升值不但不能减少贸易逆差,反而扩大贸易逆差,反之反是。文章通过一系列实证检验和对比研究,发现上述作用机制在2005年7月至2008年6月的中美贸易中能够较好地成立。

How entrenched managers beat earnings expectations before and after SOX

This study investigates the relationship between managerial entrenchment and how firms meet or beat earnings forecasts. It further examines whether this relationship changes before and after the Sarbanes–Oxley Act (SOX). We find that, in the pre-SOX era, entrenched managers meet or exceed analyst forecasts more often than their unentrenched counterparts when analysts’ initial forecasts are high. This is mainly due to the drop in analysts’ consensus rather than earnings management. These results nearly disappear in the post-SOX era.
