The edge as stored

Residential construction requires input Softwood lumber2 evidenceMechanism supported

Residential construction depends on Softwood lumber.

Mechanism

Most new single-family homes in the United States are wood-framed, so lumber demand tracks starts. Steel framing and masonry substitute in some markets, which is why this is a market mechanism rather than a universal engineering requirement.

What each rung means

Levels

Level 0: No association found
the overlapping data show no significant association.
Level 1: Correlation only
statistically associated in the overlapping periods; no direction, no mechanism.
Level 2: Predictive lead/lag
one series historically contains predictive information about the other.
Level 3: Mechanism supported
a documented physical, economic or institutional mechanism with cited evidence.
Level 4: Causally supported
a backdoor-adjusted estimate that survived refutation, on stated assumptions.
Level 5: Established relation
follows from engineering, accounting or scientific structure.
