The role of interpersonal trust in cryptocurrency adoption
No full textInternational audienceDespite the impressive adoption of cryptocurrencies since Bitcoin was introduced in 2008, little academic attention has been paid to the role of interpersonal trust in fostering this adoption. In this paper, we quantify the effect of interpersonal trust on the interest in and adoption of the three largest cryptocurrencies by market capitalization – Bitcoin, Ethereum and Litecoin using data from the 7th wave of the World Values Survey, Twitter, and Google Trends. Our results indicate a positive and statistically significant effect of trust on interest in and adoption of cryptocurrencies, confirming the importance of trust in the growth of financial markets
Conveying product weight in digital media using a hand image
No full textInternational audienceThe present research examines the role of the image of a hand in an online product evaluation. Through eleven studies (i.e., six in the manuscript and five in the Web Appendix), we show that, when a hand image is depicted in an unsupported holding position (i.e., lifting a product), consumers’ confidence in their judgment of the product's weight is enhanced. This outcome increases product evaluation, purchase intention, and product choice. The hand image effect is mediated by a mental representation of a haptic experience (i.e., haptic imagery). Additionally, we show that an image of a hand in an unsupported holding position increases consumers’ confidence in the product's weight, while other hand positions or their absence do not have a similar impact. Online retailers can use our findings to employ hand images to influence the evaluations and purchase intentions of products in which weight is a salient haptic attribute
Alternative governmental carbon policies on populations of green and non-green supply chains in a competitive market
No full textInternational audienceAs a severe challenge to governments, air pollution threatens many lives annually. This paper develops an evolutionary game theory model for supply chains (SCs) to encourage firms to reduce carbon emissions. A government dictates three carbon policies: carbon cap, carbon tax, and cap and trade. We construct six scenarios according to the carbon regulations and SC functions (i.e., centralized versus decentralized ones). First, the profit function of SCs that are the input of the game matrix is formulated, and optimal final prices and quantities of products are obtained. Then, an evolutionary game-theoretic model is formulated to analyze the behavior of populations by obtaining the evolutionary stable strategy under each scenario. In addition, three models of government intervention are presented, considering the cost associated with environmental pollution and government net revenue. Finally, a case study of motorcycle production dissects the results. The findings demonstrate that cap and trade can be introduced as an incentive policy since it encourages SCs to adopt green strategies and improves their profit. A carbon tax policy also succeeds in pressuring SCs to apply green strategies. However, a carbon cap policy fails in forcing SCs to adopt green strategies. Finally, it is concluded that decentralized supply chains (DSCs) handle high tax rates better than centralized supply chains (CSCs)
A dynamic programming approach to optimal pollution control under uncertain irrevesibility : the poisson case
No full textInternational audienceWe solve a bimodal control problem with a non-concavity and certainly through a Poisson process underlying the transition from a mode to another. We use a dynamic programming approach and are able to uncover the global optimal dynamics (including optimal non-monotonic paths) under a few linear-quadratic assumptions, which do not get rid of the non-concavity of the problem. This is in contrast to the related literature on pollution control under irreversibility which usually explores local dynamics along monotonic solution pahs to first-order Pontryagin conditions
Contingent self-esteem, social interaction fears, and compulsive WeChat usage
No full textInternational audienceThis research examines the impact of contingent self-esteem on compulsive usage of social media application WeChat in China. The authors attempt to identify the channels based on self-verification and self-determination theory and propose that fear of negative evaluation (FNE) and fear of missing out (FoMO) transfer the impact of contingent self-esteem (CSE) to compulsive WeChat usage (CWU). Additionally, these relationships were tested with frustration about unavailability (FaU) as a moderator in the framework to explain the phenomenon. By employing a convenience method, 396 samples of Chinese students were analyzed. The analyses indicate that CSE contributes to CWU directly and indirectly through FNE and FoMO. Furthermore, FNE mediates the link between CSE and FoMO, ultimately transferring the effect of CSE to CWU in series. These results can enhance our knowledge of how CSE affects CWU, a growing problem among young people today. Our results may guide psychologists to prepare a counselling programme for compulsive social media users and help them overcome social interaction fears in the real world
The Role of Sustainability and Innovation in Financial Services Business Transformation
No full textInternational audiencePurpose: This study discusses the effects of transformative service in the financial sector. Unlike conventional research, it reports how business transformation can play a vital role in human well-being. The main objective is to reveal how financial services can affect the welfare of people, communities, regions, and worldwide perspectives. Design/Methodology/Approach: The study used Confirmatory factor analysis and Structural Equation Modeling using SPSS (Amos). Findings: While appreciating the role of consumers as agents of service-driven business transformation, the study demonstrates how service transformation can promote an ecosystem that helps to accomplish rising sustainability goals. Originality: The main focus was to explain how social and environmental sustainability, responsible consumption and innovativeness are related to a firm’s attractiveness, value creation and customer satisfaction. Research Limitations: This study uses a cross-sectional survey design and it doesn’t have a holistic approach for all stakeholders. Predominantly, it considers the customer as a change agent in business transformation. Practical Implications: The study discusses a broader customer perspective instead of an extremely narrow and limiting traditional dyadic firm-customer perspective. It can enhance responsible production and consumption. It develops a comprehensive framework to help academicians, service leaders, and policymakers to recognize and solve service systems’ unsustainability. Social Implications: The research contributes to addressing, understanding, upgrading, and integrating the financial service system for business transformation, which can positively influence individuals and collectives.Source : editor
Deposit or reward: Express packaging recycling for online retailing platforms
No full textInternational audienceTo motivate consumers’ participation in recycling, we study two recycling policies for express packaging on an online retailing platform equipped with self-run logistics to collect express packaging from consumers. First, under the Deposit-Refund Policy (DRP), when consumers purchase from the platform, they pay a deposit for the express packaging, but the deposit will be refunded if they return the packaging to the platform. The other is the Recycling Reward Policy (RRP), under which the platform provides rewards when consumers return express packaging. The platform decides whether to recycle the express packaging and chooses the optimal recycling policy if recycling is economically feasible. To investigate, we first set up an optimization model to analyze these two recycling policies. Using the No Recycling Policy (NRP) as the benchmark, we then derive managerial insights through comparative analysis and numerical studies. Our results indicate that the consumers’ green consciousness plays a critical role in decision making. Specifically, NRP is optimal for the platform when the green consciousness level is low. As the consumers’ green consciousness level increases to a medium range, recycling becomes feasible and RRP is optimal. If the green consciousness level is high, DRP will be the optimal policy. These findings have helpful implications for corresponding decisionmakers (e.g., express industry managers, government departments) to cautiously judge whether to recycle express packaging and which recycling policy is best under different circumstances
The virtuous circle between green product innovation and performance: The role of financial constraint and corporate brand
No full textInternational audienceAlthough the nexus between green product innovation (GPI) and firm performance has been studied, the impact of GPI on firm performance remains little understood and findings have been mixed. These mixed results of prior studies are attributable to failures to incorporate the intervening mechanism in studying the nexus between GPI and firm performance and to examine the impact of closely interlinked pertinent internal boundary conditions. This study attempts to overcome these shortcomings and contributes to the relevant literature in three significant ways. First, the findings indicate that GPI impacts a firm’s financial constraint, which affects its current and anticipated performance. Second, the relationship between GPI and financial constraint is moderated by a firm’s corporate brand equity. Third, GPI is both a predictor and a consequence of financial performance, indicating that the relationship between the two constitutes a virtuous circle. The results are robust to alternative measures of the performance variable and the alternative model estimation method
Simulation-Based Models of Multi-Tier Financial Supply Chain Management Problem: Application in the Pharmacy Sector
No full textInternational audienceA crucial role in the continuation of economic activities is played by the financing of services and production in supply chains. A key element of optimizing the financial flow of these complex networks is to pay attention to the financial aspects of these complex networks since they are becoming more and more complex and expanding. This study aims to investigate the supply chain of a pharmaceutical company’s holding company and its subsidiaries while using internal resource valuation to develop a new strategy for financing the company’s operations. There is a process of money circulation through the chain, which consists of passing through two treasuries (primary and secondary), which provide liquidity to compensate the deficits of some institutions with the excess liquidity of other institutions. In this article, we present three simulation-based models based on a case study conducted at Shafa Darou Investment Company in Tehran-Iran, a leading pharmaceutical investment company in the country, to examine the impact of implementing this idea in the real world. Considering the study’s results, it has been shown that the supply chain as a whole has improved in terms of its working capital. Using a set of local treasuries is generally associated with reducing risks and a greater level of stability when relying on the excess liquidity of chain members provided that financial independence from external institutions, such as banks, is maintained. In addition, if the members’ excess liquidity is deposited in a set of local treasuries rather than a bank, the profit and internal financial flow within the chain will be circulated throughout the chain, and more added value will be generated
The Demand for Trade Protection over the Business Cycle
No full textInternational audienceWe build measures of the demand for trade protection, and relate them to permanent productivity and transitory monetary shocks identified from U.S. data. The demand for trade protection is countercyclical conditional on productivity shocks and procyclical conditional on monetary shocks. A two‐country dynamic stochastic general equilibrium (DSGE) model with trade in intermediate and final goods, sticky prices, and incomplete financial markets is proposed, in which tariffs are determined in a repeated noncooperative policy game. The resulting trade policies are consistent with the empirical evidence about the cyclical pattern of trade protection demand
