The Arithmetic of the 2025 Carbon Tax Proposal

A $40/ton initial price carbon fee yields $1.8 trillion over a decade, but distributional analysis shows severe regressivity without the companion dividend mechanism. We ran the numbers.

Research Domains

Tax Reform & Revenue

Evaluating corporate rate adjustments, wealth tax administration costs, and VAT proposals against historical OECD baseline revenues.

Housing & Infrastructure

Zoning reform impacts, federal transit funding efficiency, and the arithmetic of public-private partnerships in urban rail.

Healthcare Finance

Medicare negotiation pricing models, single-payer transition arithmetic, and hospital consolidation impacts on regional premiums.

Run the numbers yourself.

Policy shouldn't be a black box. We open-source our demographic and economic models. Adjust the assumptions, change the parameters, and see how the bottom line shifts. No coding required.

The Danger of Static Scoring

Legislative debates often rely on static revenue scores that assume economic actors will not adjust to new incentives or penalties. We reject this premise.

By incorporating baseline elasticities derived from peer-reviewed empirical literature, our dynamic models provide a more accurate forecast of a policy's true fiscal and economic impact.

"A policy is only as effective as the arithmetic beneath it. Intent does not alter the budget deficit."
— Core Principle 01

Data Archives & Open API

The models driving our policy analyses are accessible via our open JSON API. Researchers and journalists can query baseline elasticity estimates, historical revenue series, and infrastructure cost benchmarks directly.

State Capacity & Execution

A policy is only as effective as the institution executing it. We explicitly model administrative drag—the cost, delay, and friction introduced by regulatory compliance, enforcement, and state-capacity constraints.

Whether evaluating a wealth tax or a high-speed rail line, the bottleneck is rarely capital; it is execution bandwidth.
