Reproducible research is fundamentally important and is not done well in social sciences e.g., here or here or here.
My data and research code is freely available here: https://github.com/pmpk20/
The code for my thesis is pretty horrible, but I promise the more recent scripts are better.
Let me know if there is anything missing - sometimes estimation objects are because they are really large filesizes.
If you are a student in choice modelling/survey methods and have a questions on why/how I did something, please feel free to email me.
Final replication code for "Willingness-to-pay for precautionary control of microplastics, a comparison of hybrid choice models" (Journal of Environmental Economics and Policy, 2023, https://doi.org/10.1080/21606544.2022.2146757) is available here: https://github.com/pmpk20/PhDHybridChoiceModelPaper
Not particularly nice code be warned.
Final replication code for "Stated preferences for the colours, smells, and sounds of biodiversity" (Ecological Economics, 2025, https://doi.org/10.1016/j.ecolecon.2024.108410) is available here: https://github.com/pmpk20/WinterPaper and here: https://data.kent.ac.uk/480/
Okay this I'm mostly happy with. Some chatgpt-inspired tidying helped.
Scripts numbered according to order of execution.
If some output data is missing that's bc the filesize is insane. I might be able to email it you if need.
Final code and anonymised data for "How confident are you in the ability of experts to provide reliable information? Evidence from a choice experiment on microplastics" (Environment and Development Economics, 2025) is publicly available here: https://github.com/pmpk20/PhD_CEPaper
This one starts with cleaned data already, the actual raw survey responses -> cleaned data is in my PhD repo, but the rest of the paper can be replicated from here.
I report session information for the scripts to run on my machine, but let me know if there is some issue.
