When a new product of a well-known brand is released, consumers wait in line as early as possible to increase their chances of purchasing the product. This research investigated the two-stage competitive arousal model of a new product purchase competition. Results of a structural equation modeling with a multi-group analysis approach showed that competitive arousal was a central psychological state stimulated by product uniqueness, scarcity, popularity, need for uniqueness, and self-enhancement value, influencing the intention to queue in line. Practical insights in targeting the right consumers and promoting a new product to draw optimal attention from consumers were further discussed. 相似文献

The alignment between corporate strategies and the Sustainable Development Goals (SDGs) can be an indicator of long-term sustainability success. But which types of companies are most, and which are least, aligned with the SDGs? This paper scores how 67 economic activities—as a proxy for companies' operations and the goods or services they deliver—interact with 59 SDG targets. It then uses network analysis to define which activities are most and least aligned with the SDG Agenda. The results reveal four types of corporate activities, each having a strategic sustainability imperative: (i) “core activities” predominantly generate positive, while having few negative, impacts on the SDGs, challenging companies to scale their contributions to further align with the SDG Agenda; (ii) “mixed activities” have moderate/high degrees of both negative/positive impacts, posing a decoupling imperative; (iii) “opposed activities” provide few benefits yet cause significant adverse impacts, implying that companies must transform in order to better align with the SDGs; and (iv) “peripheral activities” have immaterial positive and negative impacts, creating an imperative to explore innovative avenues for creating SDG contributions. Detailed network graphs are presented that map companies' interactions with the SDGs and guide the creation of corporate sustainability strategies. Policy implications include the potential for using companies' activities as a lever for adopting a “nexus approach” to the SDGs. 相似文献

This paper aims to assess the effect of public procurement for innovation (PPI) in the Brazilian oil and gas sector on the innovative behavior of suppliers. It emphasizes the role PPI may play in developing countries due to its ability to target a wide range of firm sizes and to contribute to a more even diffusion of technical progress. Using microdata from RAIS and coarsened exact matching, results show that treated firms present on average a higher intensity of innovative efforts than the control sample. In small firms, PPI has a positive effect on the probability of carrying out innovative activities. Once small firms have decided to carry out these activities, treated and control samples have similar innovative effort intensities. The treatment’s effect on large firms’ probability of performing innovative activities is positive but lower than small firms. Nonetheless, there is a significant and positive effect on the intensity of these efforts. The paper suggests that, due to its effects over a wide range of firm sizes, PPI may be a worthwhile policy to implement for the reduction of structural heterogeneity present in developing countries. 相似文献

在我国,海上保险采用被保险人主动告知模式。相较于陆上保险的询问告知模式,无论在理论层面还是审判实践中,主动告知义务一直存在告知界限不清晰的问题。告知义务界限不明确,会使被保险人与保险人在实务中多有讼争。本文以《海商法》第二百二十二条为研究对象,从被保险人和保险人两个角度出发,厘清海上保险告知义务的界限。具体来说,就是以被保险人的视角界定应当告知事项的判断标准,再辅以保险人的立场说明何为无需告知的情形,即告知义务的除外情形。 相似文献

面对新型冠状病毒肺炎的突袭,尽管全球在抗疫起初表现出正反两种态度和行为,但世界各国伴随抗疫实践的深入而对珍爱健康、休戚与共、合作共赢等全球治理理念作了深度反省和逐渐共识,进一步表明筑牢疫情防控命运共同体是历史的必然、国际的呼声。从时代价值来讲,筑牢疫情防控命运共同体进一步加强了人与自然和谐共生的自然命运共同体意识,夯实了团结统一的民族命运共同体,推动了人类命运共同体的新高度。从实践路径来讲,要树立人民群众战疫胜利信心,筑牢人民群众抗疫共同体;完善疫情防控的制度机制,提升政府公共卫生治理能力;加强疫情防控国际合作,推进人类健康命运共同体。 相似文献

Based on the social identity theory, this study examined the relationship between paradoxical leadership and employees’ service performance in the hospitality industry. Data were collected from a multisource, time-lagged survey of 72 leaders and 556 employees in eight full-service hotels in China. Using hierarchical linear modeling, paradoxical leadership was found to be positively related to employees’ leader identification, which consequently enhanced their service performance. Furthermore, the level of an employee’s need for cognitive closure moderated the relationship between paradoxical leadership and leader identification such that paradoxical leadership exerted a stronger positive influence on leader identification for those employees with a lower need for cognitive closure. These findings have implications for both paradoxical leadership and hospitality management practices. 相似文献

This paper describes the structure and estimation of a Social Accounting Matrix (SAM) of Kenya for the year 2014. Among its specificities, this SAM includes a very high disaggregation of the agri‐food sector and accounts for the double role of households as producers and consumers. Accounting for these characteristics is crucial to provide robust socioeconomic analysis in the context of developing countries. Indeed, this type of database is valuable to perform ex‐ante evaluations of economic policies with various economic models and techniques. In this paper, we present an application with a linear multiplier analysis (backward linkages and value chain decomposition). The results show the capacity of the primary sector in Kenya to generate value added and employment, with this growth distributed more intensely in rural households whose main livelihood is semi‐subsistence agriculture. 相似文献

Less Favoured Areas (LFA) were designated to support farming activity on land with limited productive potential. However, progressive land abandonment in these areas questions the rationale and targeting of support payments to maintain viable farming enterprises. Using micro level data on farm businesses over the period 2003-2016 matched to land capability and spatial data we identify the distribution of viable and vulnerable enterprises in Less Favoured Areas. We find five categories of household based on progressive quality of life thresholds, namely i. vulnerable, ii. sustainable, iii. viable, iv. resilient, and v. robust. A proportional odds model measured the effect of biophysical and remote disadvantage on predicting these states of viability, along with farm family lifecycle factors. Whilst we would expect higher proportions of disadvantaged farmland to be negatively related to viability, when combined with rural remoteness this increases the magnitude of the effect. However, clear succession planning and tenancy arrangements suggest that approaches to management of the business and the farm family life-cycle may overcome some of these disadvantages. These results have to be considered against the UK’s planned withdrawal from the Common Agricultural Policy. This offers opportunities to provide a more nuanced approach to targeting and supporting disadvantaged regions beyond current criteria. However, there would seem to be dissonance between the proposed payment for public goods agenda, which is results orientated, and support for correcting natural disadvantages where opportunities for delivery of these public goods will be limited. 相似文献
