Work Package 2: "Understanding Change Potential"
We are going to do some state-of-the-art travel mapping, secondary and revealed preference data collection, and dynamic stated adaptation choice experiments.
I'm building a demo survey in-public here - let me know what you think.
Working (2023 - 25) on the NERC-funded DRUID project under Prof. Martin Dallimer.
Work Package D1: Quantifying the economic value of insect natural capital across the UK
I developed economic production functions (new to me!) to simulate lost crop yield value across different levels of natural enemy and pest presence across three different UK crops.

Work Package D2: Measuring the cultural values of insect natural capital.
I designed, deployed, and analysed a large (N = 1,684) stated preference survey to evaluate WTP for cultural ecosystem services provided by UK insects.

Chatgpt, Claude, Gemini and I wrote this Shiny app (left) that shows you how your self-reported wellbeing from insects compares to our latent classes. Feel free to play around: Here [Note: this is the free-tier of shiny]

Working (2021 - 23) on the ERC-funded RELATE project under Prof. Zoe Davies.
Work Package 5: I analysed ~7000 responses to choice experiment data.
The winter paper took a while but thanks to the efforts, time, and patience of the entire RELATE team and reviewers and editors at Ecological Economics, we got it sorted.
Replication code, data, survey design, and Ngene: https://github.com/pmpk20/WinterPaper with the entire survey printout here: https://data.kent.ac.uk/480/
We found that:
Respondents were willing to pay for an increased variety of colours, smells, and sounds in forests. They may also be willing to pay for changes in the quantity of deadwood for decomposition in forests.
Findings were very scope-sensitive. We discuss implications for (a) CE design, (b) forest management.
The contribution here is (1) sensory attributes, (2) in-depth mixed-methods pre-testing is really useful for embedding public preferences into these types of methods.
What changed in review:
Adding way more nuance to our claims about (a) pre-testing and embedding participatory methods in CE designs, (b) scope-sensitivity, (c) implications for management.
We dropped the plot in-text of the conditional WTP estimates but as I really liked the idea, it kind of lives on in Figures B1 and B2.
We also deleted the spatial analysis (no global or local clustering of preferences for sensory attributes) which might see the light of day eventually, or maybe not!
Updated robustness of the mixed logit models for (i) pref-space/WTP space, (ii) different covariate specifications, (iii) with/out correlations, (iv) different interactions with sensory impairments.
