Repugnant market

A repugnant market is an area of commerce that is considered by society to be outside of the range of market transactions and that bringing this area into the realm of a market would be inherently immoral or uncaring. For example, many people consider a market in human organs to be a repugnant market or the ability to bet on terrorist acts in prediction market to be repugnant. Others consider the lack of such markets to be even more immoral and uncaring, as trade bans can create avoidable human suffering.
