The chocolate supply chain exemplifies the social and environmental challenges within global food systems. Growing awareness of environmental impact and ethical production practices is increasingly shaping consumer choices and influencing food policy. This highlights the need for an integrated...

This study aims to evaluate the strength of various indicators related to seven types of food consumption motives, sustainable food choices, and food waste management variables in distinguishing the motivation and latent behaviour of Generation Z Indonesia through Item Response Theory analysis....

This study evaluates a randomized trial in Côte d’Ivoire, implemented by the Africa Gender Innovation Lab (GIL), which tested whether varying the content and recipient of SMS reminders can increase enrollment among young people who had pre-registered for a skills training program. Messages...

Behavioral design in smartphone apps aims at inducing certain, monetizable behavior, mainly increased engagement, measurable by usage time. Such design is rarely transparent and often restricts users' ability to make alternative choices. In a framed field experiment, we document that behavioral...

We test whether AI-generated news images affect outlet demand and trust. In a preregistered experiment with 2,870 UK adults, the same article was paired with a wireservice photo (with/without credit) or a matched AI image (with/without label). Average newsletter demand changes little. Ex-post...

Platformisation and the growing adoption of AI-driven systems have intensified pervasive data extraction and appropriation that bring distinct harms for both individuals and societies at large. Yet, little is known about how distinct harm perceptions shape citizens' preferences for different...

Platforms that provide product recommendations to consumers, such as marketplaces like Amazon or online travel agencies like Expedia, govern a substantial part of transactions in many markets. In addition to selling via platforms, most firms, however, also operate a direct channel. This paper...

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 develops an axiomatic framework for decision making when preferences depend not only on the current alternative but also on the past frequency with which alternatives have been chosen. We identify key independence axioms that characterize frequency-dependent preferences. In addition,...

Last-mile delivery, the final leg of the supply chain to consumers, significantly impacts the environment, particularly in the grocery sector, due to the perishable nature of food items often necessitating expedited delivery methods. The role of consumer behavior in this process has been...

Within the framework of the circular economy, extending the lifespan of electrical products through repairing them is a promising approach, particularly against the backdrop of growing e-waste levels. Consumers play a key role in facilitating repair and multiple studies have suggested their...

I study how the cognitive demands of financial planning shape household decisionmaking with respect to consumption out of windfall income shocks. I build a quantitative model of bounded rationality in which reoptimization is costly. Households respond to windfall income shocks by choosing a...

How borrowers respond to future changes in the interest rate on their debt matters for the transmission of monetary policy and for household financial stability. Combining bank data, a letter RCT, and a survey, we study this question in the context of the German mortgage market, where since 2022...

The digitalization of finance has accelerated the diffusion of FinTech and raised new questions about how AI, data security and blockchain shape consumer behaviour. This article examines current FinTech users, focusing on mobile banking, security perceptions, AI-enabled personalisation and trust...

This study experimentally examines how tax administration service inefficiencies in the form of tax return processing delays from paper-filed tax returns indirectly affect taxpayer tax evasion intentions through taxpayers’ psychological reactance to the delay. We further consider whether this...

Purpose - Social media has transformed brand communication and how consumers perceive brands. While social media influencers (SMIs) have emerged as key players in digital marketing, their impact on brand equity within the automobile sector remains underexplored. This study examines the impact of...

Designing shared road spaces that accommodate multiple modes of transport is central to promoting active travel, but engagement can be hindered by perceptions of danger and unfairness, especially among groups more worried about navigating shared spaces. This study used an online randomised...
