🕰️ Background
Amazon’s dominance in e-commerce and labor markets raises questions about monopsony power — market power on the buyer side. As the largest US employer (1.5M+ workers) and largest e-commerce platform (40%+ US e-commerce share), Amazon exerts downward pressure on both worker wages and supplier pricing. The HQ2 competition (2017-2018), where 238 cities competed to offer Amazon billions in incentives, illustrated Amazon’s buyer power over entire municipalities.
❓ The Central Problem
When does buyer market power become harmful? Monopsony (when a buyer has market power over sellers/workers) is less studied than monopoly but potentially equally damaging. Amazon’s dual monopsony — over suppliers AND labor — illustrates both sides.
📊 Analysis
Supplier monopsony: Third-party sellers depend on Amazon’s marketplace for access to customers. Amazon sets fees (15-45% of sale price), controls Buy Box placement, and can copy successful products with AmazonBasics. Sellers have limited alternatives. Labor monopsony: In warehouse towns, Amazon may be the dominant employer. Research shows Amazon warehouse wages suppress wages at nearby businesses by 2-6%. The HQ2 competition demonstrated: when 238 cities competed, Amazon extracted $3B+ in tax incentives — the municipalities competed against each other, not Amazon.
🔑 Key Lessons
- Monopsony power (buyer market power) can depress prices paid to suppliers and wages paid to workers below competitive levels
- Platform dependency creates supplier monopsony — when 60% of your revenue comes from one platform, you have no negotiating power
- Employer dominance in local labor markets depresses wages even without explicit collusion
- Governments competing to attract large employers can destroy more value in incentives than they gain in jobs
🎓 Discussion Questions
- Does Amazon’s marketplace benefit or harm third-party sellers? How would you measure net effect?
- Is Amazon’s labor market power comparable to historical company towns? What policy responses are appropriate?
- Should cities be allowed to compete for corporate headquarters with tax incentives?
