The issue of religious belief and its role in economic activity, entrepreneurial behaviour, attitudes toward work and capital, and the formation of markets has been generally ignored throughout the disciplines of management and economics. This e-book brings together papers that illustrate our increasing effort to understand the complex calculus between the forces that frame economic and firm behaviour and the cultural and moral foundations that emanate from our notions of religion, spirituality and belief. Together with theoretical papers examining the impact of religious orientation on perceptions of market justice and entrepreneurial activity, authors study traditions and practices amongst the Yoruba people of Nigeria and the Amish of Pennsylvania.
