DiPasquale-Wheaton Four-Quadrant Model

Solves the DiPasquale-Wheaton four-quadrant model to a long-run equilibrium rent, asset price, construction rate, and stock, and shows the rent overshoot that follows a demand shock while supply catches up. Inputs are the demand index, cap rate, depreciation rate, and replacement cost.

DiPasquale-Wheaton Four-Quadrant Model

Market conditions

The four quadrants solve together to one long-run equilibrium. Raise the demand index above 1.0 to fire a demand shock and watch rent overshoot, then mean-revert as supply arrives.

Demand index (E)

Cap rate (i)

Depreciation / decay (δ)

Replacement cost (C₀)

Long-run equilibrium: walking the box

Construction

2.00M sf

New building / yr

C = γ·(P − C₀)

Asset market

$500/sf

Equilibrium price

P = R ÷ cap rate

Stock adjustment

100.0M sf

Equilibrium stock

S = C ÷ δ

Space market

$30.00/sf

Equilibrium rent

R = (α + θE − S) ÷ β

At the baseline demand index the box closes on a stable equilibrium: rent $30.00/sf, price $500/sf, stock 100M sf, construction 2.00M sf/yr exactly replacing decay. Raise the demand index to fire a shock and trace the overshoot.
