There is a wikipedia page with lots of content. Some useful characteristics are: - free entry and exit: people can enter as suppliers or exit. Many markets are like this. Some aren't such as hospitals in most states in the US where you have to get a certificate of need, and it will only be granted if yours won't affect existing ones. - mostly homogenous fungible products: you can do this for shoes, eggs and solar panels since they are substantially the same. This is significantly less true for nuclear submarines for the military because they are custom designs, and limited to builders with appropriate blessing and security clearances - available information: the demand side can get information about the supplies on offer. You can do this for shoes and pretty much most things that have lots of reviews on Amazon. You can't for US healthcare since even pricing info isn't available in advance, nor is exactly what you are going to get.
