Why and when organizational culture fosters affective commitment among knowledge workers: the mediating role of perceived psychological contract fulfilment and moderating role of organizational tenure

Drawing on Denison and Mishra (1995)’s framework of organizational culture, this study examines why and when organizational culture is related to knowledge workers’ affective commitment. Data were collected from 640 employees working in three high-technology companies in China. The findings indicate that the relationship between organizational culture and affective commitment is mediated by perceived psychological contract fulfilment. In addition, organizational tenure moderates the relationship between two external dimensions (i.e. adaptability and mission) of organizational culture and perceived psychological contract fulfilment. This study extends the current theoretical framework of organizational culture by demonstrating the underlying mechanism and the boundary condition of the relationship between organizational culture and affective commitment. The findings also provide practical implications for international managers to design appropriate human resource management policies and practices in China.     

Are nontariff measures and tariffs substitutes? Some panel data evidence

Using new estimates of ad valorem equivalent of nontariff measures (NTMs) over time, this paper examines NTMs and tariffs’ relationship for a sample of 70 economies for 4,949 products at the 6‐digit harmonized system level over the period 2003–2015. A panel data methodology models the lagged adjustment of NTMs to tariffs, consistent with a causal relationship. Trade policy substitution is found when the models are estimated in both levels and changes; with this holding for both OECD and non‐OECD countries, but not for the agriculture sector in OECD countries. Overall, there is a fairly complete substitution between policy instruments in absolute terms.     

基于因子及聚类分析的甘肃省14市州区域软实力综合评价

区域软实力是促进区域协调发展的有效助力，软实力建设是推动西部地区高质量发展的必要前提。本文立足于甘肃省，在研究国内文献的基础上，从区域文化、公共管理、人力素质、区域形象、宜居环境五个方面构建了区域软实力的评价指标体系，采用了因子分析和聚类分析等方法，从软实力指数、类型及排名等方面入手，对甘肃省各地区的软实力进行了综合评估。结果显示，甘肃省各地区的软实力情况可分为五类，区域间软实力发展不够均衡，差异性较大。为此，各地区可根据评估结果，正视自身软实力现状与发展差距，借鉴榜样地区的经验与做法，合理调配资源，切实提升软实力。     

名义负利率传导机理与传导效果:文献综述

在全球经济复苏乏力、新冠疫情持续冲击的背景下,名义负利率政策再度成为热议话题.本文在简要梳理主要国家的政策实践后,系统介绍了名义负利率政策的传导机理和传导效果,并讨论了其主要争议与未来展望.总的来说,名义负利率政策与传统利率政策的传导机理大致相同,仅在政策调控模式和操作工具等方面略显差异.名义负利率政策在调节汇率方面表现出色,在传导效率和对金融机构的影响方面存在争议,短期内在提振通胀方面略见成效,长期内可能存在着扭曲经济结构等多方面的非线性影响.名义负利率的政策实践具有很强的借鉴意义,其长期效果及退出等问题有待进一步研究.未来可结合数字货币的应用,对负利率的下限问题作进一步分析.     

基于双重属性的商业模式构念化与研究框架建议

商业模式是创业研究的新兴主题,既有研究文献增长迅猛,但研究结论高度零散、矛盾甚至冲突,不少学者认为缺乏概念明确性是导致商业模式研究喧嚣混沌状况的根源,但鲜有研究对此做出积极的理论探索。本文首先梳理并提炼商业模式概念的演变及其理论逻辑,发现既有研究的不足并提炼商业模式如何创造价值的架构属性,基于不同理论视角形成了不同的概念维度,特别是对于商业模式如何塑造竞争优势的价值属性研究不足。进一步地,本文构建了基于双重属性的商业模式构念化与分类模型,目的在于整合并澄清学术界对于商业模式概念的学理性认识,同时基于该模型重新审视商业模式研究框架并提出未来研究亟待关注的关键问题,以期对商业模式形成、调整及其效应机制的理论发展和实证检验起到推动作用,最后提出了国内学者开展商业模式研究的启示和建议。     

Non-tariff and overall protection: evidence across countries and over time

This paper analyzes the evolution of the incidence and intensity of non-tariff measures (NTMs). It extends earlier work by measuring protection from NTMs over time from a newly available database and provides evidence on the evolution of NTMs. In particular, building on Kee et al. (Econ J 119(534):172–199, 2009), this paper estimates the ad valorem equivalents of NTMs for 97 countries at the product level over the period 1997–2015. We show that the incidence and the intensity of NTMs were both increasing over this period, with NTMs becoming an even more dominant source of trade protection. We are also able to investigate the evolution of overall protection derived jointly from tariffs and NTMs. The results show that the overall protection level, for most countries and products, has not decreased despite the fall in tariffs associated with multilateral, regional and bilateral trade agreements in recent decades. We also document an increase in overall trade protection during the recent 2008 financial crisis. Overall, this study sheds light on an under-researched aspect of trade liberalization: the proliferation and increase of NTMs.

Leisure,international retirement migration,and retirement adjustment: insights from the best exotic marigold hotel movies

ABSTRACT

International retirement migration (IRM) is a growing phenomenon linked to increased longevity, early retirement, and improved financial status. Encompassing both travel and leisure experiences, IRM is a topic relevant to both tourism and leisure studies. By analysing the fictional movie series The Best Exotic Marigold Hotel (2012) and The Second Best Marigold Hotel (2015) from psychological, gerontological, and sociological theoretical perspectives, this paper examines motivation, goal setting, continuity and change, and identity development in IRM experiences within tourism and leisure contexts. This paper (a) identified motivations for IRM as finance, romantic relationships, social relations, self-esteem, self-fulfilment, and social norms; (b) in turn, time perception and attitude influence IRM emigrants’ priority and emotional fulfilment; (c) innovation extricates IRM emigrants from role loss and facilitates role change; and (d) IRM emigrants experience various identity development processes. A conceptual framework for IRM is proposed that purports to explain the IRM experience process and indicates that such an understanding of IRM should incorporate psychological, gerontological, and sociological perspectives.
