Bargaining Game, Principal Agent
The King's Bargain
The King's Bargain is a Bargaining Game and Principal Agent scenario. The core lesson: Rulers who bargain for taxes in exchange for protection and enforceable rights build more durable revenue than rulers who simply seize, because credible constraint is what makes subjects willing to pay. You rule a mid-sized European kingdom in the seventeenth century. A rival power is massing troops on your frontier, your treasury is nearly empty, and your standing army will desert if it goes unpaid through the spring. DecisionPlay maps the players, payoffs, and equilibrium dynamics that shape how this situation typically resolves.
