Augmented reality experiences and sensation seeking

Studies about augmented reality (AR) largely discuss the design of applications and adoption behaviours of the AR system. Attempts to understand user experiences with AR are scarce, especially in the field of tourism. This paper contributes to this gap by identifying travellers' experiences with AR applications when obtaining travel information. More specifically, this study applied the concept of sensation-seeking to segment travellers to better understand their AR experiences. An online questionnaire was designed and completed by a sample of 1042 study participants who all used an AR app in the course of this study. The results demonstrate the applicability of sensation-seeking to explain heterogeneous AR experiences. Of the four sensation-seeking elements, experience-seeking and boredom-susceptibility were identified as key elements to classify the travel groups in the context of AR applications. Managerial implications for tourism marketers are suggested.     

中国OFDI技术创新效应的传导机制——基于资本要素市场扭曲视角的分析

本文尝试构建一个中国OFDI(对外直接投资)技术创新效应传导机制理论框架,并对资本要素市场扭曲影响OFDI技术创新效应的作用机制和结果进行拓展分析。研究表明:近年来中国企业OFDI对技术创新具有正向效果,且OFDI企业可以通过从劳动密集型向资本密集型的转型升级、提高管理效率以及生产效率这三个重要途径实现其技术创新能力的跃升;现阶段中国资本要素市场扭曲现象会显著抑制企业OFDI技术创新效应,作用机制是,资本要素市场扭曲作为干扰外部摩擦因子,通过降低企业资本要素密集度和生产效率等渠道抑制企业OFDI技术创新效果。本文进一步提出构建知识产权金融化建议,包含知识产权股权化、知识产权证券化和知识产权流动性机制等内容,以此引导更多金融资源和人力资源参与企业技术创新活动。     

全球股票市场间风险传染的测度、监管及预警

近年来,伴随金融一体化程度的加深,全球各股票市场间风险传染的动态复杂性加剧,其准确测度、高效监管及实时预警已成为优先事项。本研究选取全球21个代表性股票市场作为分析样本,首先基于广义向量自回归模型的滚动估计准确测度其间风险动态传染的高维网络序列,进一步借由矩阵值因子模型来稳健收缩上述序列,以探究其潜在动态核心结构,从而实现高效监管。最后,通过向量自回归模型的预测功能实现对全球股票市场间风险传染的实时预警。研究表明,全球股票市场间风险传染具有时变性,其监管与预警可通过少数与地理区域高度相关的风险区域间的动态传染关系及内部的市场构成来刻画。与此同时,我们发现中国内地等新兴市场的重要地位逐渐凸显。本文研究结论可为有效防范与化解金融风险提供有益参考。     

The influence of knowledge-based factors on taxi competitiveness at island destinations: An analysis on tips

Mobility at the destination is an important element of the tourism system on islands. Tourists have mobility needs that are often met by trains, buses, taxis and other means of transport there. The competitiveness of the taxi industry can be strategic for destinations because it is an industry with a traditional high proportion of entrepreneurs and SMEs. The knowledge-based view has contributed to understand firm performance better, and knowledge-based factors can be crucial for taxi competitiveness. The impact of taxi drivers' knowledgebased- aspects on tips are analysed, since this last factor is an interesting proxy for competitiveness due to its link to tourist satisfaction and potential loyalty. The empirical approach of this work is based on a survey in Gran Canaria, Spain. Knowledge of foreign languages (with mixed results), driving knowledge and knowledge creation seem to exert a significance influence on tips and play a relevant role in taxi competitiveness.     

The stock market effects of a securities transaction tax: Quasi-experimental evidence from Italy

In the aftermath of the financial crisis, in several countries new levies on the financial sector have been proposed and in some cases implemented. We focus in particular on the recent introduction of a securities transaction tax (STT) in Italy. A peculiarity of the Italian STT is that it only concerns stocks of corporations with a market capitalization above € 500 million. We exploit this feature via a differences-in-differences approach – comparing taxed and non-taxed stocks before and after the introduction of the tax – and via a regression discontinuity design – comparing the performance of stocks just above the threshold with those just below. Focusing on the regulated market, we find that the new tax reduced liquidity, but it left transaction volumes and returns substantially unaffected. There is also evidence – although not conclusive – that the tax increased volatility.     

The hybrid tourist

Inspired by the recent emergence of the hybrid consumer in the marketing literature, the present article defines hybrid tourists and assesses empirical evidence of their existence. Results indicate that hybrid tourists—tourists whose segment membership for the next trip cannot be predicted from their segment membership of their last trip—are the norm, rather than the exception. Only one quarter of tourists remain in the same motivation segment across more than one trip. Results are similar for expenditure segments. Tourist hybridity exists both with respect to travel motivations and expenditure. Personal characteristics predict hybridity. New approaches of market segmentation are needed to cater for the hybrid tourist.     

Dynamic ambidexterity: How innovators manage exploration and exploitation

Firms must excel at both exploration and exploitation to ensure long-term survival and prosperity. However, firms often have difficulties in doing so because they have to accommodate the contradictory logics of exploration and exploitation. This article examines the logics of exploration and exploitation, evaluates the difficulties of accommodating both logics, and identifies dynamic ambidexterity as a new way to overcome these difficulties. To achieve dynamic ambidexterity, firms need to support structural ambidexterity at the corporate level, contextual ambidexterity at the business-unit level, and sequential ambidexterity at the project level. I believe that the notion of dynamic ambidexterity and its managerial practices can help firms manage exploration and exploitation and ensure long-term survival and prosperity.     

Is late really better than never? The farmer welfare effects of pineapple adoption in Ghana

Export agriculture offers potentially high returns to smallholder farmers in developing countries, but also carries substantial market risk. In this article we examine the intertemporal welfare impact of the timing of a farmer's entry into the export pineapple market in southern Ghana. We examine whether farmers who never cultivated pineapple are better or worse off than farmers who decided to adopt pineapple earlier or later relative to their peers and experienced a significant adverse market shock several years prior to our endline survey. We use a two‐stage least squares model to estimate the causal effect of duration of pineapple farming on farmer welfare. Consistent with economic theory, we find that earlier adoption of the new crop brings greater welfare gains than does later uptake. But we find that the gains to later uptake of pineapple—just before the market shock—are small in magnitude, just 0.1 standard deviations of a comprehensive asset index, indicating that the gains to adoption may be precarious and depend on the context, in particular on the severity of prospective market shocks.     

政府行为对风险投资回报率影响研究

国际上西方主流观点认为,风险投资最好是由民间资本为主,政府不应该操纵风险投资,而中国现在的风险投资大多是由政府主导的资金对政府感兴趣的公司进行投资,风投公司大多是政府主导建立的,民营上市公司参与风投的比例较低,民间资本创立的风投机构更是少之又少。而通过对四类风险投资公司的分析,初步探究出中国政府应该:第一,转变政府在风险投资中的干预职能和行为方式,放宽进入门槛,建成风险投资的多元性投资主体。第二,要利用其所掌握的管理权资源和政策制度引导,通过适当的政府行为选择指引,将大部分精力放在风险投资需要的外部环境建设、制度的制定与完善上。第三,提升政府在风险投资发展中的决策水平。政府应根据风险投资运行的本质规律,建立科学的经济决策程序和决策体系。     

知识型员工冗余对中小上市公司二元创新的影响：环境特征的调节作用

以277家中小板和创业板上市公司2012-2017年平衡面板数据为样本，利用泊松模型，实证分析知识型员工冗余与企业二元创新的关系，并探讨外部环境特征（要素市场发育程度和市场不确定性）的调节机理。研究表明：企业应保持一定的知识型员工冗余，促进企业二元式创新，过多或过少的知识型员工冗余均不利于企业开展创新活动；不同的环境特征对二者间关系的调节作用存在异质性，要素市场发育程度会减弱知识型员工冗余与探索式创新、利用式创新间关系，而市场不确定性会加强知识型员工冗余与探索式创新、利用式创新间关系。
