This document outlines a research experiment on the effects of price matching guarantees. The experiment aims to show that price matching guarantees can limit competition and cause implicit collusion by removing incentives for firms to compete on price. The theoretical framework is that in normal market conditions without price matching, firms are incentivized to undercut each other's prices until they reach the marginal cost. However, price matching guarantees are expected to inhibit this process and keep prices above marginal costs. The purpose is to demonstrate that price matching guarantees stifle competition and cause implicit collusion, and that firms prefer markets with price matching abilities over those without. The methodology will involve modifying a classic market experiment to introduce price matching guarantees and observe their effects.
