Determinants of the intention to participate in firm-hosted online travel communities and effects on consumer behavioral intentions

The increasing presence of firm-hosted online travel communities is motivating significant changes in the travel industry. This study attempts to explain consumers’ intentions to participate in such communities, and other consumer behavioral intentions, on the basis of a model that integrates the Theory of Planned Behavior, the Technology Acceptance Model, and Social Identity Theory. In addition, this research investigates the link between the intention to participate in a community and two behavioral intentions that may benefit the host firm: the intention to use the firm’s products/services and the intention to recommend the host firm. The results reveal that the chosen theories provide an appropriate framework for explaining the intention to participate; this intention in turn has a positive effect on the two other behavioral intentions. On the basis of the results, the authors propose some key conclusions and managerial implications.     

The role of house prices in the monetary policy transmission mechanism in small open economies

We analyse the role of house prices in the monetary policy transmission mechanism in Norway, Sweden and the UK, using structural VARs. A solution is proposed to the endogeneity problem of identifying shocks to interest rates and house prices by using a combination of short-run and long-run (neutrality) restrictions. By allowing the interest rate and house prices to react simultaneously to news, we find the role of house prices in the monetary transmission mechanism to increase considerably. In particular, house prices react immediately and strongly to a monetary policy shock. Furthermore, the fall in house prices enhances the negative response in output and consumer price inflation that has traditionally been found in the conventional literature. Moreover, we find that the interest rate responds systematically to a change in house prices. However, the strength and timing of response varies between the countries, suggesting that housing may play a different role in the monetary policy setting.     

货币政策冲击对实体企业投资选择影响的“宿醉效应”

本文研究货币政策冲击对实体企业投资选择的动态影响效应。与传统分析方法不同,本文运用利率衍生品价格数据来识别中国货币政策冲击,利用工具变量局部投影法获得货币政策冲击对微观实体企业投资选择的动态影响效应。研究表明,动态效应呈现出更丰富的信息:货币政策冲击对企业金融资产占比有显著驱动效应,效应大小表现出先升后降趋势,在冲击发生一年半后达到峰值。值得注意的是,货币政策冲击会导致企业货币资金占比在短期内显著减少,而在中长期显著增加。进一步分析表明,货币政策冲击使实业投资和金融投资在短期内都更有利可图,所以在短期内企业倾向于减少货币资金占比,增加非货币金融资产投资和实业投资;政策冲击在中长期对企业资产收益率的提升作用消退,盈余效应使企业在中长期的金融资产占比提高,表现出一定的“宿醉效应”。     

Cow‐Calf Producer Preferences for Voluntary Traceability Systems

This article identifies preferences of US cow‐calf producers for voluntary traceability systems to better identify the potential success of alternative voluntary traceability systems. Results suggest that notable heterogeneity exists between cow‐calf producers in their preferences and the welfare effects of mandating traceability adoption. Producers are sensitive to price, managing entity and information requirements. We provide forecasts of voluntary participation rates under different price premium and discount scenarios that producers may face. This analysis has policy implications as success of voluntary traceability systems hinges critically upon cow‐calf producer preferences.     

人口流动与初婚机会:福音还是梦魇?——基于CGSS2015数据的分析

大规模人口流动已成为中国社会转型期的重要时代特征,人口流动给个体初婚带来怎样的影响?基于CGSS2015数据,运用Cox比例风险模型对此进行了实证分析。结果显示:人口流动总体上推迟了初婚年龄,降低了初婚风险率;人口流动对初婚风险率的负向影响呈现代际递增趋势;与女性相比,农村男性流动在一定程度上提高了初婚概率,但不能从根本上改变其初婚不利处境;社会阶层地位对个人初婚有重要影响,不仅直接促进了个人初婚,也显著降低人口流动对初婚的负向影响;在扩大的婚姻市场中,农村底层男性成为婚姻竞争的失败者,也是婚姻挤压情境下终身不婚风险的主要承担者。贫富分化和阶层固化透过婚姻市场的竞争规则得以强化和延续。农村底层男性所面临的阶层边缘化和初婚机会减少的双重困境,需引起政府和学界的高度重视。     

方言能力如何影响流动人口收入? ——基于中国劳动力动态调查数据

探讨流动人口的方言能力和收入关系对于理解人口流动的经济社会后果具有重要意义。基于方言的认同效应和替代效应,提出并证实了方言水平和收入的非线性关系命题:总体而言,流动人口的收入和方言水平呈倒U型曲线关系;同时,随着流动距离增大,两者关系由U型曲线转变为倒U曲线;当满足一定流动距离条件时,收入和方言水平的关系亦表现出一定的线性特征。上述关系在不同性别、教育程度、行业、区域样本中具有异质性。在控制了方言测量误差、工作经验和普通话水平等因素后,结论仍然是稳健的。研究表明,流动人口掌握适度的方言有利于实现收入最大化,这也为认识普通话推广和语言文化多样性保护的关系提供了参考。     

基于模态识别的高速铁路列车票额预分优化研究

票额预分是高速铁路列车票额现代化管理的重要技术手段,为客运组织实现挖潜提效、精细化管理起到关键作用,但长期存在过度裂解或过度保护的问题,导致高速铁路列车区段运输能力存在虚糜现象。通过分析高速铁路列车票额预分现状,从接续预分、模态内聚预分和复合模态预分顺序优化等方面,构建基于客流模态识别的高速铁路列车票额预分优化模型,以北京西—成都东的G571次高速铁路列车票额预分为例,研究结果表明基于模态识别的高速铁路列车票额预分能够更好地实现存量票额在始发站和沿途站的科学预分,有效提升高速铁路列车客座率和收入水平。
