Our study investigates the impact of price matching guarantees (PMGs) on consumer behavior in online retail markets. Leveraging a Difference-in-Differences (DiD) approach, we analyze product ratings in response to price changes during PMG policy periods. Results show that PMGs alone have no significant effect on ratings, but price increases during PMG periods lead to lower ratings. Furthermore, the effect strengthens over time, particularly for cheaper and less visible products. These findings suggest that PMGs may serve as effective market signals of pricing strategy, especially for items where price sensitivity is higher or visibility is lower. This underscores the importance of signaling mechanisms in influencing consumer perceptions and responses in online retail settings. From an antitrust perspective, our results highlight the potential for PMGs to influence competition dynamics and consumer welfare. Policymakers may need to consider regulations ensuring pricing transparency and consumer protection in online markets, balancing the benefits of market signaling with the risks of anti-competitive behavior and consumer harm. Overall, our study contributes to the understanding of pricing strategies and consumer behavior in digital markets, with implications for both industry practices and regulatory interventions.

Abstract

Our study investigates the impact of price matching guarantees (PMGs) on consumer behavior in online retail markets. Leveraging a Difference-in-Differences (DiD) approach, we analyze product ratings in response to price changes during PMG policy periods. Results show that PMGs alone have no significant effect on ratings, but price increases during PMG periods lead to lower ratings. Furthermore, the effect strengthens over time, particularly for cheaper and less visible products. These findings suggest that PMGs may serve as effective market signals of pricing strategy, especially for items where price sensitivity is higher or visibility is lower. This underscores the importance of signaling mechanisms in influencing consumer perceptions and responses in online retail settings. From an antitrust perspective, our results highlight the potential for PMGs to influence competition dynamics and consumer welfare. Policymakers may need to consider regulations ensuring pricing transparency and consumer protection in online markets, balancing the benefits of market signaling with the risks of anti-competitive behavior and consumer harm. Overall, our study contributes to the understanding of pricing strategies and consumer behavior in digital markets, with implications for both industry practices and regulatory interventions.
