I’m currently compiling a list of examples of pro-market arguments in the academic literature that are based on the benefits of trade to the trading parties. I’m especially interested in arguments that defend trades that are often considered unethical, such as trade in kidneys. The sort of thing I’m looking for would be “Cherry defends allowing markets in kidneys on the grounds that trade in kidneys would not occur unless both the seller and the buyer ex ante believed that it would be to their advantage.” Any pointers would be greatly appreciated!
