This study asks whether Ethereum’s proof-of-stake (PoS) incentives not only make economic sense on paper but also feel attractive to real validators who may be loss-averse and sensitive to risk. We take a canonical Eth2 slot-level model of rewards, penalties, costs, and proposer-conditional maximal extractable value (MEV) and overlay a prospect-theoretic valuation that captures reference dependence, loss aversion, diminishing sensitivity, and probability weighting. This Prospect-Theoretic Incentive Mechanism (PT-IM) separates the “money edge” (expected accounting return) from the “felt edge” (behavioral value) by mapping monetary outcomes through a prospect value function and comparing the two across parameter ranges. The mechanism is parametric and modular, allowing different MEV, cost, and penalty profiles to plug in without altering the base PoS model. Using stylized numerical examples, we identify regions where cooperation that pays in expectation can remain unattractive under plausible loss-averse preferences, especially when penalties are salient or MEV is volatile. We discuss how these distortions may affect validator participation, economic security, and the tuning of rewards and penalties in Ethereum’s PoS. Integrating behavioral valuation into crypto-economic design thus provides a practical diagnostic for adjusting protocol parameters when economics and perception diverge. Full article

The benefits of the servicizing business model, in which a firm sells the use or functionality of a product rather than the product itself, extend beyond attracting new customers and driving economic growth. Aligned with circular economy principles, servicizing promotes sustainability by encouraging firms to enhance product durability and customers to be more mindful of their amount of usage. However, the lack of product ownership may lead to product misuse, negatively affecting both economic and environmental outcomes. This study addresses product misuse as a major risk to servicizing firms’ performance and investigates whether, and under what conditions, adopting Behavior-Dependent Pricing (BDP) can mitigate this risk. Leveraging digital technologies such as the Internet of Things (IoT), we develop a BDP model in which a firm monitors customers’ usage behavior and provides monetary incentives for more sustainable use. We identify conditions under which BDP leads to a win–win–win outcome by increasing firm profits, enhancing customer utility, and reducing environmental impacts. This study provides firms with insights on how and when servicizing can be less vulnerable to product misuse risk that could undermine profitability, thereby encouraging adoption of the servicizing business model and generating economic and environmental benefits.

This study examines how government policy tools shape consumer adoption of battery electric vehicles (BEVs) in Taiwan. By extending the Technology Acceptance Model (TAM) focusing on three external government policy factors—legislative direction, monetary incentives, and usage-based benefits—this study uses two factors, including perceived usefulness (PU) and perceived ease of use (PEOU), to evaluate behavioral intention to use (BI), or purchase, BEVs. Utilizing PLS-SEM, survey data from 238 respondents were analyzed. The results suggest that legislative direction had no significant impact on PU or PEOU, while monetary incentives influenced only PEOU. In contrast, usage-based benefits strongly predicted both PU and PEOU. In addition, PU also partially mediates the relationship between PEOU and BI. These findings extend the TAM by situating public policy as a measurable driver of technology adoption, especially in the case of BEVs. For Taiwan, the results suggest that governmental policies focused on increased visibility and accessibility are more attractive than abstract regulatory frameworks in encouraging BEV adoption.

Understanding the mechanisms behind academic buoyancy, the ability to effectively cope with everyday academic challenges, is essential for identifying the factors and mechanisms that help students maintain their motivation and cope with routine academic pressures. One potential underlying mechanism is reward sensitivity, or the capacity to experience pleasure both in anticipating and receiving reward-related stimuli. We hypothesized that individuals with higher sensitivity to anticipated reward would exhibit greater academic buoyancy. To test this in an academic context, we modified the Monetary Incentive Delay (MID) task into a School Grade Incentive Delay (SGID) task, where participants work towards a fictitious school grade by winning or losing points on each of the trials. In this study, we investigated whether the SGID activates the neural reward circuitry similar to the traditional MID and whether this is associated with academic buoyancy. The SGID task activated key brain regions associated with reward anticipation, validating its use for studying reward processing in academic contexts. Importantly, we found a negative association between academic buoyancy and right amygdala activation during reward anticipation, suggesting that buoyant students may benefit from reduced emotional reactivity when anticipating rewards. Further research in larger samples is needed to capture the full complexity of reward processing in relation to academic buoyancy. Full article

This study investigates the relationship between monetary and non-monetary motivations and financial and non-financial job performance among non-academic staff in Chinese universities. Using data from 356 respondents, analyzed via Structural Equation Modeling (SEM-PLS) with Smart-PLS4, this study finds that both incentive types significantly affect performance. Monetary incentives such as salaries and bonuses primarily enhance financial performance; on the contrary, non-monetary incentives such as training, career advancement, and supportive work environments have a stronger impact on nonfinancial performance, including job satisfaction and service quality. The findings underscore the importance of implementing balanced motivation strategies that integrate both financial rewards and developmental support. From a policy perspective, this study recommends customized incentive systems to improve administrative effectiveness and contribute to the strategic development of universities. These insights offer practical guidance for strengthening human resource practices and maximizing the performance of non-academic personnel in the context of higher education in China. Full article

Apologies can offer solace and compensate for intangible and emotional harm in social and legal contexts. In some areas of law, an apology offered by a defendant will be factored into the assessment of damages awarded to vindicate the plaintiff’s rights and compensate for loss. This is the case in Australia, the jurisdiction primarily considered in this article, and in many other jurisdictions. There is a danger, however, of assuming that because apologies are compensatory in some sense, they can be used as a basis to reduce damages in tort law more generally. Even though general damages for non-pecuniary loss in fault-based torts are incommensurate to a monetary amount, they are still intended to compensate for actual loss. Empowering defendants to reduce their damages exposure by apologizing might incentivize meaningful apologies which are valued by plaintiffs. It might also create perverse incentives for plaintiffs and defendants alike, further unbalancing a system in which plaintiffs are already at risk of under-compensation. And it raises uncomfortable questions of evidence, reciprocity, agency and expertise which are yet to be fully explored. We argue for these reasons that it is not currently defensible to reduce an award of general damages for negligence, especially for personal injuries, on the basis of an apology by the defendant.

This paper proposes an incentive scheme based on a public–private partnership (PPP) to encourage low-carbon travel behavior by inducing the mode choice shift from private cars to public transit. The scheme involves three key entities: travelers, the government, and the private sector. Travelers can choose between private cars and public transit, producing different emissions. As the leader, the government aims to reduce total emission to a certain level with limited budgets. The private sector, as an intermediary, invests subsidies in low-carbon rewards to attract green travelers and benefits from a larger user pool. A two-layer multi-objective optimization model is proposed, which includes travel time, monetary cost, and emission. The objective of the upper level is to maximize the utilities of the private sector and minimize social costs to the government. The lower layer is the user equilibrium of the travelers. The numerical results obtained through heuristic algorithms demonstrate that the proposed scheme can achieve a triple-win situation, where all stakeholders benefit. Moreover, sensitivity analysis finds that prioritizing pollution control strategies will be beneficial to the government only if the unit pollution control cost coefficient is below a low threshold. Contrary to intuition, larger government subsidies do not necessarily lead to better promotion of low-carbon travel. Full article

California’s SB 1014 (Clean Miles Standard) mandates ridehailing fleet electrification to reduce emissions from vehicle miles traveled, posing financial and infrastructure challenges for drivers. This study employs a mixed-methods approach, including expert interviews (n = 10), group discussions (n = 8), and a survey of full- and part-time drivers (n = 436), to examine electric vehicle (EV) adoption attitudes and policy preferences. Access to home charging and prior EV experience emerged as the most statistically significant predictors of EV acquisition. Socio-demographic variables, particularly income and age, could also influence the EV choice and sensitivity to policy design. Full-time drivers, though confident in the EV range, were concerned about income loss from the charging downtime and access to urban fast chargers. They showed a greater interest in EVs than part-time drivers and favored an income-based instant rebate at the point of sale. In contrast, part-time drivers showed greater hesitancy and were more responsive to vehicle purchase discounts (price reductions or instant rebates at the point of sale available to all customers) and charging credits (monetary incentive or prepaid allowance to offset the cost of EV charging equipment). Policymakers might target low-income full-time drivers with greater price reductions and offer charging credits (USD 500 to USD 1500) to part-time drivers needing operational and infrastructure support.

The rapid growth of e-commerce and surges in shipment volumes have increased the pressure on transport systems, requiring innovations in collaborative logistics where consumers participate in dual roles as receivers and deliverers. However, existing research often addresses these roles in isolation, overlooking the flexibility with which users switch between them. Moreover, the literature has focused predominantly on monetary value in paid crowdsourced or social value in free social delivery, without fully exploring how users perceive value across both models. Addressing these gaps, this study profiles users of collaborative logistics services from both receiver and deliverer perspectives and examines their motivations in paid and unpaid delivery contexts. Based on survey data from 493 participants in Singapore, cluster analysis identified four distinct user segments: hesitators, potential customers, active users, and loyal advocates. The findings indicate that user preferences differ by role, with functional value prioritised in paid delivery and social value more prominent in free models. Free models attract a higher proportion of favourable users, highlighting the significance of non-monetary incentives. This study contributes to the literature by offering an integrated perspective on user roles and value perceptions and provides practical insights for developing more inclusive, community-oriented last-mile logistics solutions.

Grounded in motivation theory, this study examines the direct relationship between a supportive workplace environment (SWE) and employee performance (EP). The SWE has been identified into three dimensions, i.e., work recognition (WR), work motivation (WM), and career development (CD). Moreover, we focused on the mediating effect of employee engagement (EE) on the relationship between SWE and EP. A quantitative research method was used, and data were collected through a questionnaire survey. Data were collected from 349 respondents. The target population were the senior managers, middle managers, and administrative staff working in the semi-government organizations based in Riyadh, Saudi Arabia. The data were analyzed using partial least squares structural equation modeling (PLS-SEM) software version 4.0. The results indicate that in the direct relationship, workplace recognition, workplace motivation, and career development are positively connected with EP. Similarly, the findings show that employee engagement positively mediates between an SWE (work recognition, work motivation, and career development) and EP. This study suggests that managers can establish practices acknowledging and appreciating employee contributions, leading to increased motivation and improved performance. Creating a work environment that fosters work motivation by addressing employees’ physical and safety, social, and egoistic needs can further enhance employee engagement and performance. The study highlights the significant role of work recognition, work motivation, career development, and employee engagement in influencing employee performance. This study also recommends some practical implications for the semi-governmental organizations. First, it was suggested that organizations create a workplace environment in which employees feel appreciated, valued, and happy. Second, the organizations introduce the employee engagement culture at the department level as well as at the organizational level. Third, the organizations also introduce flexible work schedules for middle-level and administrative staff. Finally, Saudi organizations recognize the output of their employees and provide them with monetary incentives. Full article

Based on the Chinese government’s regulation that imposes a pay cap on the CEOs of state-owned enterprises (SOEs), we investigated how a change in institutional conditions affects firms’ green innovation. Drawing on the career concern theory, we suggest that political promotion incentives are likely to substitute for monetary incentives and influence these CEOs’ decisions and actions because the regulation reduces not only their current but also their future monetary incentives. Given that Chinese governments strongly encourage SOEs to engage in green innovation to solve environmental problems, CEOs who are more successful in this respect can demonstrate a higher level of alignment with government objectives and thus have better chances of political promotion. Therefore, we hypothesized that CEOs of SOEs generate more green innovation than CEOs of privately owned firms. We further argued that the positive relationship between the pay cap regulation and SOE green innovation is stronger in the case of CEOs with political connections and weaker in the case of younger CEOs and CEOs of firms in more munificent industries. Difference-in-difference analyses of a panel dataset including 11,061 firm–year observations of 1549 firms provide support for our hypotheses. Our study contributes to the literature on why and how institutional conditions affect firms’ green innovation. Moreover, our results imply the huge potential of the government in encouraging SOEs to promote green technology development, considering the critical incentivizing role of the political promotion concern of CEOs of SOEs.

The transition to sustainable transport poses significant challenges for urban mobility, requiring shifts in fuel consumption, emissions reductions, and economic adjustments. This study conducts a scenario-based analysis of Budapest’s transport energy consumption, emissions, and monetary implications for 2020, 2030, and 2050 using the Budapest Transport Model (EFM), which integrates COPERT and HBEFA within PTV VISUM. This research examines the evolution of diesel, gasoline, and electric vehicle (EV) energy use alongside forecasted fuel prices, using the ARIMA model to assess the economic impact of transport decarbonisation. The findings reveal a 32.8% decline in diesel consumption and a 64.7% drop in gasoline usage by 2050, despite increasing vehicle kilometres travelled (VKT). Electricity consumption surged 97-fold, highlighting fleet electrification trends, while CO₂ emissions decreased by 48%, demonstrating the effectiveness of policies, improved vehicle efficiency, and alternative energy adoption. However, fuel price forecasts indicate significant cost escalations, with diesel and gasoline prices doubling and CO₂ pricing increasing sevenfold by 2050, presenting financial challenges in the transition. This study highlights the need for EV incentives, electricity price regulation, public transport investments, and carbon pricing adjustments. Future research should explore energy grid resilience, mobility trends, and alternative fuel adoption to support Budapest’s sustainable transport goals. Full article

Mobile Crowdsensing (MCS) leverages smart devices within sensing networks to gather data. Given that data collection demands specific resources, such as device power and network bandwidth, many users are reluctant to participate in MCS. Therefore, it is essential to design an effective incentive mechanism to encourage user participation and ensure the provision of high-quality data. Currently, most incentive mechanisms compensate users through monetary rewards, which often leads to users requiring higher prices to maintain their own profits. This, in turn, results in a limited number of users being selected due to platform budget constraints. To address this issue, we propose a lottery-based incentive mechanism. This mechanism analyzes the users’ bids to design a winning probability and budget allocation model, incentivizing users to lower their pricing and enhance data quality. Within a specific budget, the platform can engage more users in tasks and obtain higher-quality data. Compared to the ABSEE mechanism and the BBOM mechanism, the lottery incentive mechanism demonstrates improvements of approximately 47–74% in user participation and 14–66% in platform profits.

Education plays an essential role in ensuring the social sustainability of blood donation. As altruism may be insufficient to support donor engagement, this study assesses the effectiveness of incentives on ensuring the social sustainability of blood donation. A self-administered questionnaire was used to collect data from 319 medical students about socio-demographic variables, donation frequency, altruism dimensions (impure, self-regarding, reluctant, egalitarian warm glow, and kinship), the perceived importance of monetary (travel compensation, meal vouchers) and non-monetary incentives (free blood screening, paid leave, refreshments, recognition gifts), and willingness to donate during a blood donation social marketing campaign in November 2021 and November 2022. Data were analyzed in SPSS 20 using chi-square, ANOVA tests, and multiple regression models. The key findings indicate no significant associations between donor categories and incentives, but meal vouchers, free medical testing, refreshments, and recognition gifts were linked to self-regarding altruism. Additionally, neither incentives, altruism dimensions, nor their interaction predicted willingness to donate blood. These findings highlight the need for education-driven approaches to ensure a long-term commitment of blood donors, by integrating educational, sustainable curricular or extracurricular activities. Integrating blood donation awareness into formal education may cultivate a culture of civic responsibility, expanding the donor pool and strengthening the social sustainability of blood donation.

Sexual violence among school-aged girls is a global health problem. Research has shown that school-aged girls experience high rates of sexual violence that often go unreported. In Kenya, one in three girls experiences sexual violence before the age of 18. Sexual violence against girls can prevent them from safely attending school and cause health issues that affect school performance. This qualitative study explored community and environmental factors associated with sexual violence against school-aged girls in Kitui County, Kenya. A total of 25 in-depth interviews were conducted with key stakeholders from Kitui South Sub County. The stakeholders were from six sectors, including the police, health, education, community, religious, and criminal justice sectors. The data were analyzed using conventional content analysis to gain an understanding of the stakeholder’s perspectives and knowledge relating to sexual violence against school-aged girls. Stakeholders frequently identified the criminal justice system, culture and traditional beliefs, and threats to well-being as barriers to reporting sexual violence offenses. Girls who experience sexual violence often contend with shame from the community, and the effects of stigma include loss of resources, additional violence, poorer marriage prospects, unplanned pregnancies, school dropouts, or abandonment. Perpetrators often threatened or bribed the families of girls who experienced sexual violence with gifts or monetary incentives to prevent them from reporting the crime to local authorities, while the criminal justice system itself presents numerous challenges for victims. The reporting of sexual violence could be increased by focusing on intervention strategies that challenge attitudes, norms, and behaviors rooted in gender inequality. By addressing the underlying causes of stigma and inequality, we can create a safer environment for school-aged girls to report sexual violence and seek justice. Full article
