We need to define some kind of treated-products group and control-products group, or in any case groups of products that it can be interesting to look at. Initial proposal: 1) medical products, covid related; 2) medical products, non-covid related, 3) non medical products. Looking at trends by product would be useful to inform group definition.
Construct and index to classify contracts to define comparison group
Differentiate between contracts/product COVID related vs contracts/products health related vs contracts/products non health related -> 3 products classification to perform analysis pooled and non-pooled
Supplier main activity
Firm registry might indicate the main activity of the company. For Romania, use the NACE codes.
