The Informal Economy makes it clear that the economic arrangements recorded in official statistics are not the only ones worth studying.
(Nancy Foner Science
[An] intensely interesting and readable set of case studies... The 'moving boundaries' of definition make is possible to include an extraordinary diversity of materials from the cocaine economy of Bolivia to the vibrant small-firm economy of the Italiam 'Red belt,' from Malaysia to Mexico City to Miami and New York. There are interesting data on informal personal incomes and outlays of the Soviet population, and an essay on the 'informalization' of the British economy under Thatcherism.
