This study investigates whether AI-driven ethical procurement systems enhance firms’ circular supply chain orientation and how governance mechanisms affect supplier cost performance. Using survey data from 393 Indian firms and structural equation modeling, the research confirms that AI-based ethical systems significantly strengthen circular supply chain orientation. Circular orientation promotes both relational and contractual governance, but only relational governance—built on trust and collaboration—improves supplier cost performance. Contractual governance shows no significant effect. The findings extend transaction cost economics by revealing that, in circular supply chains, cost efficiency depends more on flexible, trust-based relationships than on formal contracts. Managerially, the study highlights that AI and relational governance together are critical for achieving ethical, sustainable, and cost-effective procurement in the circular economy.

Loneliness is a widespread concern among older adults, profoundly affecting their well-being. Social robots—designed to engage in social interactions and form emotional connections—are increasingly perceived as social actors in human-robot relationships and offer promising potential to alleviate loneliness. This study examines how older adults interact with social robots to address different forms of loneliness and enhance their subjective well-being. Across a pilot correlational study and two experiments, the results reveal two distinct mechanisms through which social robots improve well-being: attachment for individuals experiencing emotional loneliness and social integration for those facing social loneliness. This research contributes to the literature on loneliness, transformative consumer research, and human–robot interaction.
