- CSR and quantity leadership in restaurant competitionPublication . Ferreira, Fernanda A.; Meneses, Daniela; Carvalho, Sandro; Peres, RitaThis paper investigates the critical role of Corporate Social Responsibility (CSR) in the food industry. It analyzes CSR’s impact on competition between a CSR-focused restaurant and a traditional for-profit (FP) restaurant. The research employs a game theory model to examine how each restaurant chooses the quality and quantity of its products, influenced by its differing objectives (CSR vs. profit maximization). The study’s main contributions include analyzing scenarios where a CSR restaurant competes with a traditional for-profit establishment, considering two leadership structures (CSR restaurant leading or FP restaurant leading the market), and determining equilibrium quality levels, quantities, profits, and overall social welfare in each model. This paper investigates the effects of CSR within the food industry. We develop a model where a restaurant with a CSR focus competes with a traditional for-profit (FP) establishment in determining the quality and quantity of their offerings, in the order mentioned. Yet, while the levels of quality are chosen at the same time, the quantities are determined one after the other. Our analysis considers two leadership structures: (i) the CSR restaurant leading the market; and (ii) the FP restaurant leading the market.
- Modeling Environmentally Conscious Purchase Behavior: Examining the Role of Ethical Obligation and Green Self-IdentityPublication . Kumar, Rakesh; Kumar, Kishore; Singh, Rubee; Sá, José Carlos; Carvalho, Sandro; Santos, GilbertoDue to environmental degradation, using environment-friendly products has become necessary to reduce carbon emissions. However, the consumption of such products is still below expectations because these products are usually costlier than their traditional counterparts. The current study aims to investigate consumer behavior towards environment-friendly products using Ajzen’s theory of planned behavior as a theoretical model. The study seeks to examine the role of the key determinates of environmentally conscious purchase behavior, such as ethical obligation and green self-identity. A total of 386 responses were collected from consumers living in a few major cities of northern India using purposive sampling. The data were analyzed using structural equation modeling in Amos 22.0. The results demonstrated that attitudes towards environment-friendly products perceived behavioral control and green self-identity as the major determinants of green purchase intentions. In addition, attitude was reported to mediate the effect of ethical obligation on green purchase intentions and green self-identity was found to moderate the effect of attitude on green purchase intentions. Additionally, green self-identity was also reported to moderate the relationship between ethical obligation and attitude. The study adds value to the existing literature by signifying the role of green self-identity and ethical obligation in stimulating consumers’ green purchase intentions. The findings of the study are also meaningful for marketers and policymakers.
