My List of Applied Behavioural Economics Papers to Use in Case Study Assignments

One of the things I'm trying to do this summer, is updating my database (or 'list'...) of articles I can use as case studies in my Behavioural Economics class. I used to assign these papers for a (group) presentation assignment. This year I am planning to change the assessment and turn it in a sort of 'guided case study' thing. Each student will get one paper assigned and the task is to answer a number of questions about the paper (What is the problem that the intervention tries to solve? Explain the behavioural economics concept being used here. Does it work as expected? Do you think it will scale? Give two examples of other (behavioural) economic ideas we could have used in this situation and briefly describe how they would work). I'll let know you if this new approach is a success next year...

For this assignment I need about two dozen or so appropriate and interesting papers of behavioural economic interventions being tested. My main inclusion requirements are that they need to be field experiments involving actual consumers/clients/users in real world situations. And that they need to cover a type of behavioural economics intervention that we talked about in class and that it is the type of intervention that is interesting enough to be able to write something about (so not just simplification of the application form or 'making it more personal' or things like that). The paper doesn't necessarily have to find a positive effect.

My current list is below. Some I've used for years. Some are recent additions. Maybe other lecturers find it interesting. Suggestions are very, very welcome. I am especially looking for papers that use some of the more 'exotic' behavioural economics ideas (especially the decoy effect, anchoring, positive/negative reciprocity, sunk costs, mental accounting). I've got more than enough examples that use the opt-in/opt-out effect or (descriptive) social norms. (The papers with numbers between brackets I cover in the lectures so I won't be assigning them for the assessment).

1. John & Blime (2018) How best to nudge taxpayers? The impact of message simplification and descriptive social norms on payment rates in a central London local authority, Journal of Behavioral Public Administration https://doi.org/10.30636/jbpa.11.10

- using descriptive social norms (and simplification) to increase number of people who pay their council tax. social norm doesn't work in study 1, actually backfires in study 2

2. Ebeling & Berger (2015) Domestic uptake of green energy promoted by opt-out tariffs, Nature Climate Change https://www.researchgate.net/publication/279252379_Domestic_uptake_of_green_energy_promoted_by_opt-out_tariffs

- default opt-in/opt-out selection to get more people enrolling in a (more expensive) green energy contract

3. Aysola, Tahirovic, Troxel, Asch, Gangemi, Hodlofski, Zhu & Volpp (2018) A Randomized Controlled Trial of Opt-In Versus Opt-Out Enrollment Into a Diabetes Behavioral Intervention, American Journal of Health Promotion https://journals.sagepub.com/doi/10.1177/0890117116671673

- opt-in vs opt-out to get participants to enrol in a diabetes study (they send a letter about the study)
- (significant positive effect on enrollment, optout participants are less likely to actively participate in the study though. They show this by following up with lots of additional more medicial measurements)

4. Altmann, Falk, Heidhues & Jayaraman (2014) Defaults and Donations: Evidence from a Field Experiment, working paper https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2534708

- default amounts on a charitable giving website (plus the donation to the website itself)
- (yes people give the default more but higher defaults also cause fewer people to donate. Cancels each other out. There is a significant effect of the default effect on donation 5/10/15% to cover the cost of the platform)

5. Verplanken & Roy (2016) Empowering interventions to promote sustainable lifestyles: Testing the habit discontinuity hypothesis in a field experiment, Journal of Environmental Psychology https://www.sciencedirect.com/science/article/pii/S0272494415300487

- getting hospital staff to wash their hands more by making them think about the effect on patients (instead of themselves). The paper frames it in the context of overconfidence (hospital staff more likely to think their immune) but maybe this is about altruism/social considerations?
