This study is about open innovation, which suggests that companies should aim to cooperate with other companies or organizations for green innovation. While previous research has focused on the mechanism through which the company achieves green innovation, mainly from the supplier perspective, we have taken a more demand-driven approach to product innovation by introducing the green process and consumer perspectives. Also, this study not only considers collaboration with other companies whose interests are complicated in terms of open innovation but also cooperation with other organizations whose interests are unsophisticated. We examined the relationship between open innovation and green innovation by using the structural equation method and 2496 manufacturing companies in South Korea, and further confirmed the robustness by using OLS (ordinary least square) regression. As a result of the empirical analysis, all four hypotheses were supported, and the effect of collaboration with organizations was stronger than with firms. Based on these results, this study suggests that if managers prioritize green performance, they should consider co-prosperity with other companies and organizations. In addition, this study found that green innovation, which can contribute to the environment while consumers use products with green innovation, is also becoming central. Compared with previous studies, we expect that our alternative approaches to open and green innovation will contribute to corporate sustainability in the future.

Purpose: The purpose of this paper is to investigate the mediating effects of organization-based self-esteem (OBSE) for the relationship between workplace ostracism with helping behavior, voicing behavior, in-role behavior, and deviant behavior. The workplace has now become a social context where ostracism occurs and the study emphasizes how ostracism can affect workplace behaviors.Design/methodology/approach: The study was designed using a three-wave self-reported survey. Confirmatory factor analysis, structural equation modeling, and bootstrapping for indirect effects were conducted to test the study’s hypotheses.Findings: The study found OBSE to fully mediate the relationship between workplace ostracism and helping behavior, voicing behavior, and in-role behavior, while OBSE partially mediated workplace ostracism and deviant behavior as workplace ostracism was found to have a direct effect on deviant behavior.Originality/value: The study explores and empirically tests the mediating effects of OBSE with helping behavior, voicing behavior, in-role behavior, and deviant behavior. Therefore, the study extends research on workplace ostracism by investigating beyond the direct effects of workplace ostracism on workplace behaviors.

This study investigated the moderating effects of person–corporate social responsibility (CSR)-fit for the relationships between CSR participation and job satisfaction, organizational identification, and organizational commitment. The study was conducted in South Korea and sampled 393 full-time employees from several conglomerates. The study found CSR participation to be positively related with job satisfaction, organizational identification, and organizational commitment. Furthermore, person–CSR fit significantly moderated the relationships between CSR participation and job satisfaction, organizational identification, and organizational commitment. These findings suggest that CSR participation positively affects organizational outcomes and that person–CSR fit enhances the relationships between CSR participation and the organizational outcomes. Therefore, the study suggests the importance of CSR participation and person–CSR fit in CSR initiatives, as CSR participation and person–CSR can promote a healthy work environment.

This study investigated the mediating effects of happiness and cohesion in the relationship between employee volunteerism, in-role behavior, and helping behavior. The study surveyed 312 full-time employees in South Korea, and regression analyses and the bootstrapping method were used to test the hypotheses. The study found happiness and cohesion to mediate the relationships between employee volunteerism and in-role and helping behavior. The findings suggest that employee volunteerism can promote a healthy working environment through increased feelings of happiness and cohesion as well as by improving performance behaviors.

Due to global interest in the improvement of national income and quality of life, eco-labeled food (ELF) for sustainable consumption and personal healthcare has been increasing. This study aims to contribute to two research streams by examining the quality of ELF in forests (ELFF). First, this study intends to estimate the willingness to pay (WTP) of ELFF producers for the certification verified by the government-supported institution and investigate the difference in certification costs between the actual certificating authority and ELFF producers. Second, this study aims to figure out the perception mechanism of how consumers who would like to purchase ELFFs recognize the effect of enhanced certification. These efforts may contribute to the research on how to raise interest in the production of ELF-related products and sustainable consumption. To achieve the purpose of this study, we adopted contingent valuation methods (CVM) to measure WTPs using interview-based surveys with 40 ELF producers and ordinary least squares (OLS) regression to examine the effect of certification with 112 consumers who experienced ELF consumption. Results of this study provide theoretical and practical implications by looking at the relationship between ELF certification and sustainable consumption from a stakeholder’s perspective. This study intends to expand the research field of ELF from agriculture to forestry products. It provides a basis for providing practical implications for policymakers who propose sustainable consumption.

This paper addresses an analysis of a recent debate in South Korea on energy efficiencies between a combined heat and power system with district heating (CHP-DH) and separate heat and power system (SHP) by applying a scenario analysis technique. In accordance with the Low Carbon Green Growth strategy where the rise of social awareness for energy savings is imminent, various scenarios were considered including CHP-DH (excluding waste heat recovery) versus SHP and CHP-DH (including waste heat recovery) versus SHP. To analyze the satisfaction on energy efficiency of each heating system, nationwide average field data were acquired via a survey with the help of the Korea District Heating Corporation (KDHC), and a comprehensive model for measuring sustainable value related to energy consumption, including economic (ECON), non-economic (NECON), and environmental (ENV) values were presented based on customer satisfaction (SAT). As a result of the structural equation model (SEM) and ordinary least squares (OLS) regression, variations of energy efficiencies of each heat and power delivery system are rather distinctive among different scenarios due to the performance characteristics of each system in the field. The energy savings of CHP-DH systems owned by KDHC, based on nationwide average performance, was found to be higher than the SHP system by 3.25% to 18.1%. While the effect of NECON and ENV on SAT was not significant in SHP, it was significant in CHP-DH. Based on these results, rational decisions can be made to lead the government and energy consumers to maximize energy efficiency, especially in South Korea, where the energy market heavily relies on foreign countries.
