This is a project concerning "the economy of everyday life" and habitation I am involved in. You can find my abstract for an article that I am planning to write on new views on market definitions (In Finnish).

The argument (not yet developed): Competition is not situated in the exchange between buyers and sellers, but in sociocultural terms as competition of meanings, time and relevance in everyday life.

I recommend the article by Penaloza & Venkatesh (2007) in Marketing theory 6 (3), 299-316 as food for thought on the concept of market in sociocultural terms. The article is unfortunately impossible to find in any database for the time being.
