Why REMI

Forecast the baseline.
Measure the difference.

REMI combines long-range economic and demographic forecasting with dynamic economic modeling. First, the model projects how a region is expected to evolve under current conditions—the baseline. It then models that same economy with a policy, investment, or project in place. The difference between those two paths is the economic impact.

Baseline compared with a policy scenarioTwo rising lines share a starting point in 2026 and separate over time. The dashed line is the baseline forecast; the solid line is the same economy with a policy change applied. The widening gap between them is the impact of the policy.ImpactScenarioBaseline2026203520452060Economic activity

This is a schematic, not a forecast. The size and timing of a real impact depend on the region, the policy, and the assumptions behind it.

What you get

The REMI Forecast

Walk the path ahead.
Compare what changes.

An impact isn’t one headline number — it’s a path. Each model reports the difference between baseline and scenario year by year up through 2060, across jobs, output, income, and population, so you can see when an effect arrives, how large it gets, and how long it lasts.

Published Study

Regional Jobs Generated by the Gateway ProgramNew York & New Jersey

Step through the years: construction jobs peak in the mid-2030s, then commuting and productivity benefits carry the total once the tunnel opens in 2045.

Checkpoint year: 2060

Jobs in New York and New Jersey generated by the Gateway Program, 2023 to 2060A stacked area chart of jobs in thousands, for the New York and New Jersey region. Construction of Phase 1 and Phase 2, with supporting projects, drives the total to roughly 30 thousand jobs in the mid-2030s. Once the tunnel opens in 2045, commuting, productivity, and operations and maintenance benefits sustain roughly 25 thousand jobs a year through 2060, averaging 24.4 thousand across the period.24.4k avg0k10k20k30k40k50k20232030204020502060Jobs

How it works

Dynamic Economic Modeling

Make one change.
Watch the responce.

A change in one part of the economy creates responses in the others. Employment affects population, population shifts demand, and demand moves output, prices, and trade. Rather than holding those relationships static, REMI models how they interact and evolve over time.

  • Five linked blocks
  • Feedback every year
  • No fixed multipliers
The full structure of the REMI model: five blocks — output and demand, labor and capital demand, population and labor supply, compensation, prices and costs, and market shares — connected by arrows showing how each feeds back into the others.

  1. Output & Demand

    Balances supply and demand across the economy — output, consumption, investment, government spending, imports, and exports.

  2. Labor & Capital Demand

    Sets employment and capital stock from output, wage rates, and the cost of capital, industry by industry.

  3. Population & Labor Supply

    Tracks migration, population, and labor force participation as economic opportunity shifts between regions.

  4. Compensation, Prices & Costs

    Follows wages, consumer and housing prices, and production costs as they adjust to the changes above.

  5. Market Shares

    Turns production cost into each industry's domestic and international market share — which feeds back into output and demand.
