Book excerpt: Informal economic activity, defined as exchanges made by individuals and organizations in extra-legal or non-bureaucratic contexts, represents a significant and growing share of global economic activity. The informal economy brings to mind images of street vendors in markets and bazaars throughout the developing world; indeed, informal economic activity ranges from 25-75% of economic activity, depending on the country under study. Informal activity also includes "under the table," or "off the books" business in the developed world, such as informal labor arrangements in child care, construction, or home cleaning in the United States or Western Europe. What many fail to realize, however, is the increasing presence of informal economic activity in the developed world’s largest corporations and most innovative entrepreneurial ventures, such as technology development work in Silicon Valley, open source software agreements, or employment arrangements between "technology stars" and firms. Management, Society, and the Informal Economy brings to light the role of the informal economy in the 21st century. The book does more than illuminate, however – it also calls for increased focus on the informal economy by management scholars. Each chapter contains a call to action, as well as practical and methodological advice for scholarship on the topic. Management, Society, and the Informal Economy contains a multi-faceted set of arguments, descriptions, and illustrations designed to convince management scholars that they should attend to the informal economy and view it as a serious and rigorous context for theorizing, empirical research, and even practical advocacy.
