Prisoner's Dilemma
Agency Nurse Ratchet
Agency Nurse Ratchet is a Prisoner's Dilemma scenario. The core lesson: When competing health systems bid up agency nursing rates independently, each is individually rational and collectively self-defeating. This is a prisoners' dilemma at the regional labor market level. Three health systems in the same metropolitan area are each experiencing nursing shortages. All three are drawing from the same agency pool, and each is paying a 30% premium above their last contract cycle. DecisionPlay maps the players, payoffs, and equilibrium dynamics that shape how this situation typically resolves.
The situation
Three health systems in the same metropolitan area are each experiencing nursing shortages. All three are drawing from the same agency pool, and each is paying a 30% premium above their last contract cycle. An industry association has proposed a regional rate-coordination forum. Legal counsel for each system has warned that rate coordination with competitors raises antitrust concerns. None of the systems wants to be the one that pulls back while the others keep bidding.
Background
Agency labor markets in healthcare produce classic prisoners' dilemmas when multiple health systems compete for the same supply. Each system's decision to pay a premium is rational in isolation: it fills the shift. But when all systems pay the premium, the agency captures the surplus, the nurses are not better retained long-term, and the systems are each spending more than before to maintain the same staffing coverage. Mutual restraint would leave all three better off, but without a coordination mechanism, no one will move first.
What this reveals
Why labor cost arms races are hard to stop
The agency premium ratchet is a multi-party prisoners' dilemma. Each system defects not out of malice but because cooperation without a credible mechanism is irrational. The forum offers a mechanism, but the antitrust concern is real and the legal risk must be managed. The systems that escape the ratchet are those that either change the supply structure over time or create legitimate coordination infrastructure.
How to counter it: Ask your legal team specifically what information-sharing at the forum is permissible, rather than whether to attend. 'Can we share agency fill rates and utilization data?' is a narrower question with a clearer answer than 'Can we coordinate on rates?'
