We study unconventional policy shocks and information shocks associated with central bank announcements in the U.S. While unconventional policy shocks capture the direct influence of announced monetary policy actions, information shocks are associated with central bank information conveyed with the announcement. To disentangle these two types of shocks, we impose sign restrictions on high frequency changes in interest rates and stock prices around announcements. We find that information shocks lead to persistent declines in the 10-year government bond yield, whereas the actual unconventional policy shock induces only small interest rate responses. We also find that expansionary output effects of unconventional monetary policy are to some extent counteracted by the information shock. 相似文献

近年来,劳动力价格的快速上涨已然成为中国农业生产所必须面对的内在挑战。对于机械作业难度相对较大的劳动密集型作物而言,在缓解劳动力约束瓶颈的同时,更应通过精细化的果园管理,以提高产品质量,进而提高其市场价格。然而,由于农产品具有典型的经验品属性,在信息不对称的外部约束下,农户通常难以获得应有的"质量溢价"。基于此,本文通过构建理论分析框架,以果品质量关键环节的精细管理技术作为研究对象,系统分析在劳动力价格上涨背景下农户精细管理技术投入的决策机制,以及在不同农产品质量识别程度中,劳动力成本变化对其影响的异质性,并基于全国18个省份农户的调研数据进行实证研究。研究结果表明:农户交易对象质量识别能力的提高,能够缓解农户与购买者之间存在的信息不对称性,将农产品质量信息传递给购买者,使农户获得更高的销售价格,进而在有效提高农户精细管理技术投入水平的同时,能够弱化劳动力价格对其所产生的负面影响。 相似文献

This article provides a critical review of the foundations of the new Keynesian apparatus, to evaluate the actual strength of the Keynesian inheritance. As a reference of the Keynesian vision, Fausto Vicarelli’s recognition of the Keynesian message is adopted. The critical recognition of the new Keynesian methodology focuses on its analytical foundations, the recent extensions and on the criticality of its empirical performances and controls. The new Keynesian construction is shown to lack truly Keynesian roots in at least three key theoretical features: the role of the microfoundations, the stability of equilibrium, and expectations formation. The directions of an ongoing research narrowing the new Keynesian theoretical fracture from Keynesian economics are addressed. 相似文献

The theorization of the relationship between organizational investments in career development and individual success remains underdeveloped, and empirical tests of this relationship, which have been dispersed among several disciplinary areas, have produced inconsistent results. Addressing these issues, the purpose of this article is to propose a theoretical framework that illustrates why and how organizational career management practices translate into career success and under what circumstances the relationship is effective. Using a systematic review of empirical studies on career management practices and objective success, we identify three theoretical mechanisms - developmental, informational, and relational - and two groups of contingency factors that explain this relationship. Our framework advances the extant literature on organizational career management and provides suggestions to companies for designing effective career management systems. 相似文献

Are freelancers a breed apart? The role of protean and boundaryless career attitudes in employability and career success 下载免费PDF全文
Alessandro Lo Presti Sara Pluviano Jon P. Briscoe 《Human Resource Management Journal》2018,28(3):427-442
Recent economic and organisational changes have fostered an increasing diversification of the workforce, among whom freelancers are an under‐represented population in the literature. This study aimed at examining the role of protean and boundaryless career, professional commitment, and employability activities in fostering freelancers' subjective career success. Data were collected via an online survey among a sample of 425 Italian freelancers and analysed through structural equation modelling. Results partially confirmed several hypotheses: higher self‐directed career management and boundaryless mindset predicted higher employability activities and professional commitment; moreover, employability and professional commitment acted as mediators between career attitudes and subjective career success. The study provides support for the importance of such variables to freelancers' career success, as well as for the significance of protean and boundaryless careers among nontraditional occupational groups. Interventions aimed at fostering such attitudes could support freelancers in improving their attainment of professional progress and perception of career success. 相似文献

This study investigates whether firms that are evaluating potential partners might benefit from considering how consumers view these organisations, specifically the extent to which consumer identification with local and foreign partners influences consumer satisfaction with a co-branded product and consumers’ post purchase/consumption supportive intentions towards each partner. Data came from institutions of higher education in Hong Kong and Sri Lanka that operate in collaboration with a foreign partner. A conceptual model was developed and then tested using structural equation modelling. Dual consumer–organisation identification was found to be a significant predictor of consumer satisfaction with the co-branded product and consumers’ supportive intentions towards each partner. Furthermore, the perceived identity attractiveness of each partner was significantly related to the consumers’ identification with each partner. The results suggest that organisations which indulge in collaborative arrangements with foreign firms should recognise that each partner plays a significant and distinct role in generating consumer satisfaction and positive post-purchase/consumption behaviours. 相似文献

Career mentoring in context: A multilevel study on differentiated career mentoring and career mentoring climate 下载免费PDF全文

This study explores how supervisor career mentoring contributes to contemporary organizational career development, which strives to foster employees' promotability while strengthening their intention to stay. Specifically, we focus on the implications of career mentoring in team contexts. Applying a multilevel framework, we distinguish between individual‐level differentiated mentoring (i.e., an employee's mentoring perceptions as compared to those of other team members) and group‐level career mentoring climate (i.e., the average perception across all group members). In a workplace setting, we collected data from vocational job starters (N ranged from 230 to 290) and their company supervisors (N ranged from 56 to 68). We find that career mentoring climate positively relates to promotability, more so than differentiated career mentoring. Both career mentoring climate and differentiated career mentoring are positively related to the intention to stay. At the individual level, this relationship is mediated by job satisfaction. We discuss theoretical and practical implications of differentiated and group‐level mentoring. 相似文献

为了研究网架结构的损伤检测方法,根据应变能密度理论,提出采用单元模态应变能密度差值作为网架结构损伤识别指标的方法,以损伤单元模态应变能密度差值的大小初步确定单元的损伤程度。分析了5种具有代表性的损伤工况,并在数值计算结果中引入了白噪声。结果显示,在一阶模态下,针对单损伤、多损伤和轻微损伤、严重损伤等不同损伤工况,损伤杆件的模态应变能密度差值均为高值。因此,该方法可以有效识别出网架结构的损伤位置,根据损伤单元的模态应变能密度差值大小初步确定单元的损伤程度,且在一定的噪声水平下具有较强的鲁棒性,对网架结构损伤识别具有参考价值。 相似文献

目前,员工过劳问题在我国企业发展中日益凸显,需要予以重视和解决。基于个体与组织互动角度,通过对338名企业员工的问卷调查分析职业延迟满足和职业成长机会对员工过劳的影响,并检验职业成长机会对职业延迟满足影响员工过劳的调节作用,结果表明:职业延迟满足的两个维度(工作延迟满足和职业生涯延迟满足)均对员工过劳有显著正向影响,而职业成长机会对员工过劳有显著负向影响;职业成长机会对职业延迟满足影响员工过劳具有负向调节作用,即职业成长机会越大,职业延迟满足与员工过劳的正向关系越弱。因此,企业管理者应合理引导和帮助员工做好职业生涯规划,为员工提供合适的多元化发展通道,以有效预防和缓解员工过劳。 相似文献

This research investigated how and under what conditions thriving at work affects career attitudes and behaviors. Using an experimental design (n = 174), Study 1 found that the effects of thriving on career satisfaction, career commitment, and career engagement were mediated by career resilience. The positive effect of thriving on career resilience and the resilience‐mediated effects of thriving on career satisfaction, commitment, and engagement were stronger when achievement orientation was higher. Study 2 verified these findings with a survey of another sample of 296 employees. These studies offer important insights for human resource managers and career consultants or practitioners regarding what may enhance employees' career outcomes. Our findings imply that thriving‐enabling practices might be beneficial among highly achievement‐oriented employees. 相似文献
