I am currently in the process of data collection (timeseries, panel, meta and plot level data) on minimum support price (MSP) related variables like awareness on MSP, quantity sold at MSP, marketed surplus and other household characteristics. Barring NSSO and DES, is there any other sources available on public domain? Kindly share your published papers/pre-prints/interview schedule or relevant links if you have done any research on this domain. Thanks in advance.
