I have just read A Flynn and P Davis, "Theory in public procurement research" (2014) 14 (21) Journal of Public Procurement 139-180, which had been on the "to read" pile for a bit too long. Their paper focuses on procurement/supply-chain management scholarship, which will make it seem "peripheral" for legal academics. However, I think that their findings on the need to beef up the use of theory in public procurement research will translate well to legal scholarship, particularly that of an interdisciplinary nature. Well worth reading.
