For a vigorous presentation of the core economy, see Josh Ryan-Collins, Lucie Stephens and Anna Coote, “The New Wealth of Time: How Timebanking Helps People Build Better Public Services”, New Economics Foundation, 2008. Their preferred name for it—“core economy” (rather than informal economy)—follows Edgar S. Cahn (2000), No More Throw-Away People, pp 203–204. In fact, “core economy” and “informal economy” are not quite equivalent. Core economy refers mainly to household activities, the core interactions that bring us into existence as people and on which everything else depends. Informal economy starts with this, but extends beyond—to all provision of goods and services without expectant of monetary payment.
