Behavioral Public Finance: Redesigning Systems for Real Humans
Why optimal tax design requires understanding how people actually think, not how theory assumes they calculate.
Tax Competition: Race to the Bottom or Efficient Discipline
Why mobile capital disciplines some governments while destroying others—and how international frameworks try to preserve the good competition while preventing the bad.
Designing Optimal Transfer Programs Under Information Constraints
How mechanism design principles reveal the hidden architecture of welfare programs that actually work
Fiscal Federalism: Optimal Assignment of Taxing and Spending Powers
Why the right level of government for each fiscal function depends on mobility, spillovers, and the fundamental impossibility of local redistribution.
Intergovernmental Transfers: Achieving Equity Without Destroying Incentives
Why equalizing fiscal capacity across jurisdictions risks destroying the very incentives that generate prosperity to redistribute.
Corporate Tax Incidence: Who Really Bears the Burden
General equilibrium analysis reveals how corporate tax burdens shift among shareholders, workers, and consumers through capital mobility and market structure channels.
Capital Income Taxation: The Zero-Rate Theorem and Its Many Exceptions
Why optimal tax theory both supports and undermines taxing investment returns—and how to design systems that navigate the tradeoffs.
Inverse Elasticity Rules: The Hidden Logic Behind Ramsey Pricing

Why Diamond-Mirrlees Production Efficiency Remains the Cornerstone of Modern Tax Design
Discover why taxing business inputs destroys more welfare than it raises revenue, and how this 1971 theorem still defines optimal tax architecture.
The Atkinson-Stiglitz Theorem: When Commodity Taxation Becomes Redundant
