This study investigates the impact of the increasing proportion of older workers in the workforce by establishing a theoretical framework and estimating the degree of substitutability between them and their younger counterparts.

The first step is to establish a theoretical framework that combines older and younger workers with imperfect substitutability in the production of final goods within an aggregate production function. The author then derives an equation that relates the relative wage, relative supply and elasticity of substitution between the worker types, for use in estimation. Using data from Japan’s Basic Survey on Wage Structure and Population Census from 2010 to 2019 across 47 prefectures, the author estimates the elasticity of substitution between older and younger workers in Japan.

The author finds that workers aged 55 and over and their younger counterparts are gross substitutes, and the estimated elasticity of substitution is in the range of 2.33–2.86. This implies that a 10% increase in the relative number of workers aged 55 and older leads to a fall in their relative wage in the range of 3.5–4.3%. The study estimations suggest that since 2010, there has been a convergence in the relative wage of older workers across Japan’s prefectures.

Understanding the degree of substitutability between older and younger workers is essential for quantitatively assessing the impact of workforce aging, technological advancements and labor policies on the wage distribution. This study estimates the elasticity of substitution between the two worker types based on a theoretical model, and utilizes recent datasets and methodology not adequately addressed in previous literature.

The purpose of this study is to investigate the phenomenon of knowledge transfer between employees and coworkers. That is, when and why employees engage in knowledge seeking or knowledge sabotage when confronted with coworkers with higher relative overqualification.

This study collected survey data from 315 employee-coworker pairs in East China at three-time points.

The results showed that when the cooperative goal interdependence between employee and coworker is high, the perception of coworker’s relative overqualification will cause benign envy of employees, which in turn promote employees to engage in knowledge seeking from coworker. However, when the competitive goal interdependence between employee and coworker is high, the perception of coworker’s relative overqualification will cause malicious envy of employees, which in turn promote employees to engage in knowledge sabotage toward coworker.

This research not only expands the theoretical perspective and outcomes of relative overqualification but also enriches the mechanism of knowledge seeking and knowledge sabotage. Meanwhile, this study also provides practical guidance for enterprises to reduce knowledge sabotage.

The purpose of this paper is to discuss participatory action research with staff, residents and relatives contributed to the residents’ quality of life through the development of an inclusive praxis in a public nursing home in Denmark. The project addressed the residents’ reports about a lack of influence in their everyday lives.

The project used future-creating workshops as an important methodological tool. Theoretical concepts about developing a social reflexive and colletive morally obliging praxis were central to frame democratic learning and acting. The theoretical concepts of empowerment and capability were also applied. This paper will outline the methods and the results obtained.

Learning processes were initiated, enabling staff to respectfully engage in dialogue with residents and their relatives about their needs and wishes. The development of a democratic knowledge-building process was established based on the perspectives of the residents, relatives and staff. In conclusion, the project contributed to the development of a more reflective and democratic praxis focused on empowering the residents as the primary “stakeholders” in the daily life of the nursing home.

In a dual-robot system, the relative position error is a superposition of errors from each mono-robot, resulting in deteriorated coordination accuracy. This study aims to enhance relative accuracy of the dual-robot system through direct compensation of relative errors. To achieve this, a novel calibration-driven transfer learning method is proposed for relative error prediction in dual-robot systems.

A novel local product of exponential (POE) model with minimal parameters is proposed for error modeling. And a two-step method is presented to identify both geometric and nongeometric parameters for the mono-robots. Using the identified parameters, two calibrated models are established and combined as one dual-robot model, generating error data between the nominal and calibrated models’ outputs. Subsequently, the calibration-driven transfer, involving pretraining a neural network with sufficient generated error data and fine-tuning with a small measured data set, is introduced, enabling knowledge transfer and thereby obtaining a high-precision relative error predictor.

Experimental validation is conducted, and the results demonstrate that the proposed method has reduced the maximum and average relative errors by 45.1% and 30.6% compared with the calibrated model, yielding the values of 0.594 mm and 0.255 mm, respectively.

First, the proposed calibration-driven transfer method innovatively adopts the calibrated model as a data generator to address the issue of real data scarcity. It achieves high-accuracy relative error prediction with only a small measured data set, significantly enhancing error compensation efficiency. Second, the proposed local POE model achieves model minimality without the need for complex redundant parameter partitioning operations, ensuring stability and robustness in parameter identification.

This study aims to explore the role customer satisfaction play in mediating the nexus between commitment, trust, relative dependence and customer loyalty from an emerging market context under a business-to-business (B2B) setting.

The study was a descriptive survey, and using convenience sampling technique, questionnaires were used to gather data from 356 businesses that were distributors of Guinness Ghana Company Limited. Partial least squares structural equation modeling was used to test the proposed hypotheses for this study, and macro-PROCESS was performed to test the mediating effect of customer satisfaction.

The findings show that relative dependence had the most considerable significant and positive impact on B2B partners satisfaction, followed by commitment and trust, respectively. A positive and significant relationship was also found between B2B firms’ satisfaction and loyalty. The result also indicates that customer satisfaction mediates the relationship between commitment, trust, relative dependence and B2B loyalty.

Practitioners can manipulate specific relative dependence, commitment and trust features to increase customer satisfaction with their firm’s services, thus ensuring longer-term customer loyalty.

Drawing on the social exchange theory, this study provides a more profound perspective focusing on an emerging market context, by examining from a B2B setting the significance of commitment, trust, relative dependence and B2B partners satisfaction on loyalty.

This study aims to examine the role of salespeople’s skills in relative and absolute SP in business-to-business (B2B) settings of services firms. This conceptual logic reported in meta-analytical works, that salespeople’s skills relate directly to their sales performance (SP), is questioned.

his research relies on existing theory and previous studies on SP drivers and SP measures. The literature identifies a set of common denominators on the role of salespeople’s skills regarding their SP, all of which are tested in this study. Based on a deductive approach and questionnaire survey, 732 service firms in Norway were targeted. A total of 389 questionnaires were returned, generating a response rate of 53.1%.

A total of 10 out of 12 hypothesized relationships in the research model dealing with the relationship between SP drivers and SP turn out to be non-significant. The hypothesized relationship in the research model between relative and absolute SP is also supported.

The results reported in this study, based on a large sample of service firms, empirically confirm that the direct effect is generally overestimated. Empirical evidence is provided that sheds additional light on the role of salespeople’s skills in relative and absolute SP in B2B settings of services firms.

This study offers meaningful and relevant insights into the monitoring of SP drivers to practitioners in B2B sales settings of services firms. Salespeople need to learn about gathering knowledge in training programs about each customer and their specific situation. Firms should strive to recruit salespeople who possess the appropriate skills, taking into consideration their customers and specific situations related to them, such as experiences from competitors. Salespeople may be organized around similar customers and similar customer situations, rather than geographical assignments.

Overall, this research contributes insights into the role played by salespeople’s skills in relative and absolute SP in B2B settings of services firms. In particular, the research contributes additional insights into the non-existent role of interpersonal presentation and communication skills, adaptiveness of sales approach and sales behavior skills and product/technology-related knowledge skills in salespeople’s relative and absolute SP in B2B settings of services firms.

Research has focused primarily on the antecedents that influence the risk taking of CEOs themselves. This study examines how an important event experienced by a CEO at a direct rival firm influences a CEO's risk-taking. It also examines how prior firm performance relative to aspirations moderates the relationship.

In order to test the hypothesis, the authors perform an a difference-in-differences methodology.

Using a difference-in-differences methodology, we find that when a CEO wins a prestigious CEO award, competitor CEOs increase their firm risk-taking in the post-award period. The proclivity becomes stronger when their prior firm performance relative to aspirations is better. These findings suggest that a CEO winning a prominent CEO award influences competitor CEOs' risk-taking.

This study contributes to the literature on managerial risk-taking by highlighting that a star CEO winning a prominent award may serve as a striving aspiration and induce competitor CEOs to take risks, and that two different types of aspirations – striving and competitive aspirations – interact to influence the competitor CEOs' risk-taking.

Much prior work involving director incentives and corporate behaviour has been focussing on their absolute dollar value or the intrinsic value and generated mixed findings. Comparison theories, however, suggest that the relative value of an incentive may be the main drive for individual performance. This study attempts to investigate the role of director relative pay in promoting the board’s intervention with unrelated diversification decisions.

The analysis uses data from firms operating in more than one segment during the period from 1999 to 2019. Data were obtained from WRDS databases. Ordinary least squares (OLS) regression analysis and the two-stage system generalized method of moments (GMM) were run to test the hypotheses. To test the robustness of the findings, alternative proxies for the key independent variables were used in separate analyses.

The results support the hypothesis that unrelated diversification negatively impact firm performance, while higher director relative pay will help reduce unrelated business diversification. The absolute director pay, however, has no significant impact on corporate strategic choices. The results also highlight the moderating effect of director overcompensation. Director overcompensation will cancel out the impact of relative director pay on unrelated diversification.

This study takes a fresh theoretical perspective by framing the investigation using the dimensional comparison theory to address the single untended comparison framework in the director pay structure – the intra-individual framework. It is the first to investigate the role of director relative pay in corporate strategic choices. The findings support the contention that the relative value of the incentive is an important indicator of the effectiveness of the pay.

With the use of the grey incidence analysis (GIA), indicators such as the absolute degree of grey incidence (ε_ij), relative degree of grey incidence (r_ij) or synthetic degree of grey incidence (ρ_ij) are calculated. However, it seems that some assumptions made to calculate them are arguable, which may also have a material impact on the reliability of test results. In this paper, the authors analyse one of the indicators of the GIA, namely the relative degree of grey incidence. The aim of the article was to verify the hypothesis: in determining the relative degree of grey incidence, the method of standardisation of elements in a series significantly affects the test results.

To achieve the purpose of the article, the authors used the numerical simulation method and the logical analysis method (in order to draw conclusions from our tests).

It turned out that the applied method of standardising elements in series when calculating the relative degree of grey incidence significantly affects the test results. Moreover, the manner of standardisation used in the original method (which involves dividing all elements by the first element) is not the best. Much more reliable results are obtained by a standardisation that involves dividing all elements by their arithmetic mean.

Limitations of the conducted evaluation involve in particular the limited scope of inference. This is since the obtained results referred to only one of the indicators classified into the GIA.

In this article, the authors have evaluated the model of GIA in which the relative degree of grey incidence is determined. As a result of the research, the authors have proposed a recommendation regarding a change in the method of standardising variables, which will contribute to obtaining more reliable results in relational tests using the grey system theory.

This study investigated the receptivity of the zakat wakalah system in social finance in Malaysia under the lens of innovation diffusion theory (IDT).

This study conducted quantitative research using Google Forms. The sample size was 261 respondents who participated and were useable in this study. The Statistical Package of Social Science (SPSS) 27 was employed to analyse the data. The data were collected online from August 1 till August 31, 2022.

The results reported significant effects of relative advantage, simplicity, compatibility and perceived benevolence on the zakat wakalah receptiveness index (ZAWi) for Medium Group Acceptance (MEGA) and High Group Acceptance (HIGA). As for Low Group Acceptance (LOGA), insignificant results were reported in relative advantage, compatibility and perceived benevolence but not simplicity.

This study was limited to Labuan geographically, Malaysia and the variables employed. Yet, the results highlight the factors that influenced ZAWi and the two groups namely HIGA and MEGA found them all significant.

This study enhanced the theoretical and practical effects of ZAWi. The results rendered a competitive benchmark for zakat institutions and zakat payers for improved zakat distribution policy.

This study advanced psychology and management theory by improving knowledge of zakat wakalah for effective zakat distribution. In turn, it can be employed as the baseline theory for future studies to enhance existing hypotheses.

This study introduced a new ZAWi formulated from IDT in the context of zakat distribution in Malaysia.
