Hartropp looks at the inadequacies of neo-classical economics. He compares it to the great Christian tradition of just price theory and examines the resurgence of just price economics in the Fair Trade Movement. Prices paid and received in markets should reflect justice to all the participants. Prices can be too low or too high. They can unfairly remove resources from producers, consumers, workers, the environment and traders. More than ever there is a need for justice in a global economy.
