The marketplace is a remarkable social institution that has greatly extended our reach so shoppers in the West can now buy fresh-cut flowers, vegetables, and tropical fruits grown halfway across the globe even in the depths of winter. However, these expanded choices have also come with considerable moral responsibilities as our economic decisions can have far-reaching effects by either ennobling or debasing human lives. Albino Barrera examines our own moral responsibilities for the distant harms of our market transactions from a Christian viewpoint, identifying how the market's division of labour makes us unwitting collaborators in others' wrongdoing and in collective ills. His important account covers a range of different subjects, including law, economics, philosophy, and theology, in order to identify the injurious ripple effects of our market activities.
