In some legal settings it is not possible to contract with an agent ex ante. For example, a criminal process only start after the crime was committed and only if the agent is apprehended. We study a quasilinear single-agent setting with private information and private actions in which the intervention of the designer is only triggered by certain outcomes. We introduce a property of social choice functions, *identifiability*, and show that implementable social choice functions satisfying this property can be implemented with a *tariff*, that is transfers that depend only on the realized outcome.">A Taxation Principle with Non-Contractible Events | Francisco Poggi
