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

Harsh critics have relentless exposed myriad instances of misuse, exploitation, and misrepresentation of values, customs, rituals, and religious objects, for example, by different actors, such as designers and artists, and in myriad contexts, such as in art, entertainment, and tourism. Instead of being perceived as the appreciation or preservation of cultures, as claimed, they have been condemned as cultural appropriation. Occasionally, they are deemed offensive by members of the culture of origin. In the context of destination image, tourism, and hospitality, the matter can be even more problematic as many places are economically dependent on tourism and hospitality services. A growing number of critics believe place brands in general and tourist destinations in particular have exploited indigenous groups for the commercial purpose of entertaining visitors. This article represents a pioneer effort to build awareness among place marketing scholars and practitioners, particularly in the context of tourism, of the importance, implications, and risks of cultural appropriation to the future of destination image, reputation, attractiveness, and sustainability and advances suggestions for future research.  相似文献

We conjecture that attribute satisfaction, push motives and pull motives will be positively related to return visitation of tourist destinations. We also hypothesize that push factors will be stronger related to return visitation of tourist destinations than pull factors, both directly and indirectly as mediators of the relationship between attribute satisfaction and return visitation. In addition, we predict that age and gender will moderate the effect of push and pull factors on repeat visitation. Finally, we argue that push factors and pull factors will be mutually reinforcing. To test these hypotheses, we conducted an online survey of repeat tourists’ motives, and received 986 complete responses. Survey participants were randomly chosen from a group that met a series or qualifying questions. PLS-SEM analysis of the data showed that, as we hypothesized, attribute satisfaction and push motives were positively related to repeat visitation. In contrast, pull motives were not related to repeat visitation, either directly or indirectly, but did reinforce the effect of push motives; gender did not moderate either push or pull motives and age moderated only pull motives. We discuss the theoretical and practical implications of these findings.  相似文献

ABSTRACT

Based on role theory, the article examines the images that ASEAN member governments project of their organization. It rests on a discourse analysis of 198 speeches in the United Nations General Assembly between 1998 and 2017. Findings suggest that ASEAN does not figure as a top priority for delegates and that an overarching ASEAN role conception is missing. However, their addresses reveal parameters on which a collective role conception can be built. Individual ASEAN countries undertake great efforts to project themselves as ‘good global citizens,’ a role conception that could also be applied to ASEAN.  相似文献

The study develops and extends existing frameworks of corporate identity and investigates what organisations in China perceive as essential components of the corporate identity concept including their dimensions and contents. The study adopted a qualitative approach and the method of research was a case study. Using the soft-laddering approach, and a multidisciplinary categorisation of analyses of corporate literature and websites, a systematic analysis of the corporate identity was carried out. Different from previous studies, the study reveals new dimensions on the basis of the industry practitioners’ views. The context of China has shown to influence a different focus, more significantly around the ‘impression’ that corporate identity can contribute with commercially. It is suggested that new high-tech firms in China may not have enough experience and capacity to engage in a more holistic corporate identity concept provided. The lack of such experience is particularly likely for new firms, which are still in their early stage of development. Implications for management of corporate identity in China are presented along with directions for further research in the marketing communications literature.  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

Drone food delivery services play a significant role in protecting the environment, because the services are operated by batteries that can be charged with electricity. Therefore, this study tried to examine a green image in the context of drone food delivery services. More specifically, this study proposed that a green image of drone food delivery services plays an important role in the formation of attitude toward using the services. In addition, it was hypothesized that the attitude has a positive influence on behavioral intentions including intentions to use, word‐of‐mouth intentions, and willingness to pay more. Lastly, the moderating role of gender and age was proposed during the theory‐building process. A theoretical model, which included 12 hypotheses, was developed and tested using a total of 427 samples collected in Korea. The data analysis results showed that a green image of drone food delivery services has a positive influence on attitude toward using the services, which in turn positively affects three subdimensions of behavioral intentions. Furthermore, gender and age played partly as a moderator. The current paper was the first to study the green image of drone food delivery services, so the findings of this study mean a lot to the theoretical aspect.  相似文献
