A knowledge market is a mechanism for distributing knowledge resources.[1] There are two views on knowledge and how knowledge markets can function.[2] One view uses a legal construct of intellectual property to make knowledge a typical scarce resource, so the traditional commodity market mechanism can be applied directly to distribute it.[2] An alternative model is based on treating knowledge as a public good and hence encouraging free sharing of knowledge.[2] This is often referred to as attention economy.[2] Currently there is no consensus among researchers on relative merits of these two approaches.[2]
