This article examines the EU-law challenges arising from the use of artificial intelligence for payment initiation and execution (“Payment Agents”) under European Union law. It focuses on Payment Agents that support purchasing workflows and are capable of initiating payments in both...

Negative word of mouth (NWoM) can be a major factor in new product diffusion, as indicated by Goldenberg et al. (2007). We extend their work by accounting for the role of consumer uncertainty for NWoM's impact on adoption dynamics. Using an agent-based simulation framework we compare three...

This paper examines how income inequality affects environmental outcomes through the interplay of household consumption and political support for climate policy. We develop an agent-based model in which households differ by income, consumption patterns, and climate policy attitudes. Our results...

The transition to neighborhood-scale district heating in the Netherlands frequently stalls due to the challenge of achieving a collective agreement among individual homeowners. To explore the micro-dynamics of this collective action problem, this paper introduces an agent-based model that...

Does artificial intelligence (AI) pose a threat to financial stability? We study AI investor behavior, specifically Q-learning and large language model (LLM) investors, in a mutual fund redemption problem with economic and strategic uncertainty. Different AI architectures generate systematically...
