Milei’s Odysseus Act: Monetary Commitment & Inflation Policy Simulator

Analyzing Javier Milei’s policy initiative to legally bind central bank deficit monetization. In Homer’s Odyssey, Odysseus lashed himself to the mast to resist the Sirens’ call; this simulator tests whether criminalizing seigniorage and capping fiscal deficits can anchor inflation or break under macroeconomic shocks.

Monetary Regime & Stability State
• Disinflationary Anchor
The institutional penalties for money printing are credible enough to depress inflation expectations, while zero-deficit fiscal policy prevents fiscal dominance from forcing a legal breakdown.
Theoretical Threshold: When seigniorage is outlawed but a structural fiscal deficit persists (> 2.5% of GDP), the regime risks Sudden Reversal Shock as debt markets freeze and authorities face sovereign default.
Commitment Friction Decomposition
Legal Hand-Tying Strength 90%
Fiscal Solvency Cushion 95%
External & Political Vulnerability 28%
Composite formula: $Commitment = (Legal \times 0.45) + (Fiscal \times 0.35) - (Vulnerability \times 0.40)$

Theoretical Foundations & Historical Precedents

The Kydland-Prescott Time Inconsistency

In 1977, Nobel laureates Finn Kydland and Edward Prescott demonstrated that discretionary monetary policy is fundamentally time-inconsistent: policymakers have an incentive to promise zero inflation to anchor wages, and then create surprise inflation to temporarily stimulate output. Rational agents anticipate this, generating high inflation with no employment gain.

Milei’s proposed law punishing money printing with prison seeks to eliminate discretion entirely, turning monetary policy into a binding institutional rule.

Sargent-Wallace 'Unpleasant Monetarist Arithmetic'

Thomas Sargent and Neil Wallace proved that tight monetary policy alone cannot conquer inflation if fiscal deficits persist. If the government refuses to balance its budget, borrowing will compound until debt capacity is exhausted.

At that point, either the government defaults, or the legal commitment breaks and seigniorage returns in an explosive burst of delayed hyperinflation. Fiscal discipline is the irreplaceable spine of legal hand-tying.
