The global phenomenon of political consumerism is known through such diverse manifestations as corporate boycotts, increased preferences for organic and fairtrade products, and lifestyle choices such as veganism. It has also become an area of increasing research across a variety of disciplines. Political consumerism uses consumer power to change institutional or market practices that are found ethically, environmentally, or politically objectionable. Through such actions, the goods offered on the consumer market are problematized and politicized. Distinctions between consumers and citizens and between the economy and politics collapse. The Oxford Handbook of Political Consumerism offers the first comprehensive theoretical and comparative overview of the ways in which the market becomes a political arena. It maps the four major forms of political consumerism: boycotting, buycotting (spending to show support), lifestyle politics, and discursive actions, such as culture jamming. Chapters by leading scholars examine political consumerism in different locations and industry sectors, and in consideration of environmental and human rights problems, political events, and the ethics of production and manufacturing practices. This volume offers a thorough exploration of the phenomenon and its myriad dilemmas, involving religion, race, nationalism, gender relations, animals, and our common future. Moreover, the Handbook takes stock of political consumerism’s effectiveness in solving complex global problems and its use to both promote and impede democracy.
