Future freak economist from Kyrgyzstan needs your help

From a reader named John Keaney:

I just finished your book Think like a freakand I’m trying to use the lessons in the book while I’m in Kyrgyzstan. I am a student at the University of South Carolina and while living in Kyrgyzstan, I decided to continue my first independent research project on the impact of Kyrgyzstan’s accession to the Eurasian Economic Union on the Kyrgyz informal economy and, ultimately, the political stability of Kyrgyzstan.

I’m almost ready to go to the bazaar and collect data, but I’ve been trying to find the best possible questions to ask the people who work in the stalls. So far, I have focused on questions about past prices and what they expect in the future, how they think they will be affected by the EEU, how dependent they are on market money, whether they have sons who are migrant workers. (and if they return home soon), etc.

I’ve been struggling to come up with a good fricometry for the questionnaire, but I’ve been struggling to find an unusual but important common thread between the EAEU, bazaars, household incomes, etc. and I was wondering if you could give me some advice for that dirty undergrad.

Who can give John a couple of good suggestions?
