Looking for ways to prevent price collusion with AI systems

A small group of economists from Italy, the U.K., and the U.S. has published a Policy Forum piece in the journal Science suggesting that consumers need to be protected from collusive price setting by AI systems. They also outline some possible ways to solve the problem. For most countries, price collusion is illegal. It is where two or more makers or sellers of goods get together and agree to charge higher than market prices for the goods or services they are selling. Such practices are illegal because consumers wind up paying higher prices than they would if prices were market based.
