Typology of Markets

From Ethan Miller:

The above tools could be seen, and mapped, against the following typology of non-monetary exchange types:

Householding economies — meeting basic needs with our own skills and work at home and on or with the land: raising children, offering advice or comfort, resolving relational conflicts, teaching basic life skills (such as how to talk!), cooking, sewing, cleaning the house, building the house, balancing the checkbook, fixing the car, gardening, farming, raising animals. Many types of work that have often been rendered invisible or devalued by patriarchy as "women’s work."

Barter economies — trading services with our friends or neighbors, swapping one useful thing for another: "Returning a favor", exchanging plants or seeds, time-based local currencies.

Collective economies — in their simple form these economies are about pooling our resources together (sharing): bringing food to a potluck supper, carpooling, lending and borrowing, consumer co-ops; in their most "radical" form, collective economies are based on common ownership and/or control of resources: collective communities, health care collectives, community land trusts, and more.

Scavenging Economies — living on the abundance of Earth’s own gift economy: hunting, fishing, and foraging. Also living on the abundance of human wastefulness— "one person’s trash is another one’s treasure": salvaging from demolition sites, using old car parts, dumpster diving, the "swap-shop" at the local dump.

Gift economies — giving some of our resources to other people and to our communities: volunteer fire companies, community food banks, giving rides to hitch-hikers, having neighbors over for dinner.

Worker-controlled economies — workers deciding the terms and conditions of their own work: self-employment, family farms, worker-owned companies and cooperatives.

"Pirate" economies — various activities that might be labeled "theft" by those in power, but would be called "rightful re-appropriation" by those who have been robbed of power: re-incarnations of Robin Hood or Pretty Boy Floyd, squatters.

Subsistence market economies — thousands of very small businesses survive (and sometimes thrive) with little or no imperative to grow and accumulate wealth. These are subsistence-based businesses, created and run for the purpose of providing healthy livelihood to the owners (who are often the workers) and providing a basic service to the larger community (sometimes in the indirect form of creating a community gathering space).
