I would like to know if anyone here has ever created a questionnaire to use to collect prices and product characteristics, and then use the data in the calculation of the Consumer Price Index (CPI).
What has been the logic implemented to build the questionnaire?
Has it been difficult to navigate the questionnaire in the Interviewer application?
Where can I consult examples of questionnaires developed for this task of collecting the prices of the products in the different establishments of the markets or observation points to then use to this data to calculate the Consumer Price Index (CPI)?
Thank you very much for your attention and collaboration, your experiences will be very useful to me.
I recently have worked on a CPI questionnaire together with Arthur Shaw, that allows for tailored questions per outlet, in-questionnaire checks on reported prices (using hidden prices of the previous period), options to weigh certain items (to correct the reported prices) and options to suggest new items for discontinued products.
@Arthur can confirm if I’m wrong, but I believe that these cases are handled by creating more than 1 assignment for such shops. In practice, shopkeepers may not want 1 interviewer hanging around for too long. Making more than 1 assignment either helps more than 1 interviewer tackle large shops–or encourages a single interviewer to finish work thorugh several visits to the same shop.
