In Why Some Things Should Not Be for Sale, philosopher Debra Satz takes a penetrating look at those commodity exchanges that strike most of us as problematic. What considerations, she asks, ought to guide the debates about such markets? What is it about a market involving prostitution or the sale of kidneys that makes it morally objectionable? How is a market in weapons or pollution different than a market in soybeans or automobiles? Are laws and social policies banning the more noxious markets necessarily the best responses to them? Satz contends that categories previously used by philosophers and economists are of limited utility in addressing such questions because they have assumed markets to be homogenous. Accordingly, she offers a broader and more nuanced view of markets--one that goes beyond the usual discussions of efficiency and distributional equality--to show how markets shape our culture, foster or thwart human development, and create and support structures of power.
