Federalism and Subsidiarity

Why It Matters

Centralized decision-making ignores local variation and knowledge. Decentralized decision-making ignores spillovers and coordination failures. Federalism is the principled middle: decide at the level where information and externalities are both internalized. The systematic error: assuming all decisions should be centralized (ignoring knowledge) or all decentralized (ignoring spillovers).

The Key Move

For any decision domain, ask: (1) What local information is relevant that central authorities lack? (2) What externalities affect other jurisdictions? If (1) dominates, push decision authority down. If (2) dominates, push it up. If both matter, create shared authority with clear boundaries - local control subject to federal constraints on externalities.

Classic Application

U.S. federal-state allocation. States handle education (local preferences vary, spillovers small). Federal government handles defense (no local variation matters, externalities total). Interstate commerce is shared (local implementation, federal coordination). The specific allocation is debatable, but the principle holds: match decision level to information and externality structure.

Surprising Application

Corporate org design and decision rights. Frontline teams decide local execution (they have information, minimal externalities to other teams). Executive leadership decides strategy (coordination across teams essential). Middle management mediates (aggregates local info upward, allocates resources downward). Companies that centralize execution ignore frontline knowledge; companies that decentralize strategy get incoherence. Same principle as federalism.

Failure Modes

  • Race to the bottom: when jurisdictions compete by lowering standards (environmental regs, labor protections), decentralization can produce systematic underprovision. Requires federal floor.

  • Ignoring mobility: if people/capital can move freely, local policies create externalities through migration. Changes optimal allocation.

  • False subsidiarity: pushing decisions down without resources or authority to implement. Decentralization as cost-shifting, not empowerment.
