Hold-Up Problem

The hold-up problem occurs when one party makes a relationship-specific investment and then, after the investment is sunk, the other party opportunistically demands better terms, knowing that switching is prohibitively costly. A supplier builds custom equipment for a buyer; after the equipment is installed, the buyer demands a price reduction, knowing the supplier cannot redeploy the custom assets elsewhere. The supplier faces a choice between accepting worse terms and walking away from the sunk investment. Anticipating this hazard, rational suppliers underinvest in specific assets unless governance structures (long-term contracts, vertical integration, credible commitments) protect the investment from expropriation. The problem explains why high-specificity transactions migrate from market to hierarchical governance. In AI contexts, workers investing in platform-specific skills face hold-up by platforms that can unilaterally change terms, knowing users' switching costs make exit threats non-credible.
