This post is related to an older post (here). I am starting a new post as I was advised that it is better to start a new post.
I have a data set on around 3752 farmers over three time periods. The dataset is on farmers (Respondents). They are located within villages (41 villages), located within higher geographical units called Halqa (4 in total), located within higher geographical units called tehsils (2 in total). I have this data for 3 time periods (wave1 in 2020, wave 2 in 2021 and wave 3 in 2023). Out of the 4 Halqa 2 are treated and 2 are control. Both tehsils have treated and control Halqa
Post the baseline in 2020 the treatment group was exposed to the ‘treatment’. The treatment consisted of motivations and demonstrations on the benefits of (i) latest technologies, (ii) post harvest techniques and (iii) crop harvestor. Post the treatment some of the treated group adopted the crop harvestor and some did not adopt.
My question is that how can I obtain the ‘treatment effects’ of the crop harvestor. Do I use a Difference in differences (DID) or can I use a Difference in difference in differences (DDD).
The DDD would give me the ‘treatment effects’ of the demonstrations which include latest technologies, post harvest techniques and crop harvestor. While a DDD would give me the ‘treatment effects’ for those who actually adopt the harvestor and those that do not.
