Wildfire and the Wildland–Urban Interface

Land development, home hardening, fuel treatment, spillovers, and risk-based pricing.

Economic puzzle

Wildfire hazard interacts with where people build, how structures are hardened, how vegetation is managed, and how recovery is financed. A household’s mitigation may also reduce risk for neighbors.

Question directions

• Do risk signals in insurance or property markets affect development and mitigation?
• How should local governments compare fuel treatment, building codes, and land-use limits?
• Which mitigation spillovers justify a subsidy or neighborhood requirement?
• Does public protection attract additional exposure to hazardous places?

Model hook

Decompose expected loss:

E[L]=\Pr(\text{hazard})\times\text{exposure}\times\text{vulnerability}.

Then specify which term the policy changes, its cost, and whether household or neighborhood behavior responds.

Official starting evidence

• The U.S. Forest Service Wildfire Risk to Communities datasets provide geospatial and tabular community-scale risk information.
• Local hazard-mitigation plans, building-code changes, and parcel or assessor data can describe institutions and exposure.
• State insurance regulators may publish filings, market reports, and coverage statistics.

Feasible unit of analysis

Choose one state, county, or community and one decision margin. The federal risk data are useful for community patterns, not parcel-level pricing or individual causal claims.

WarningCorrelation caution

Spatially correlated losses make wildfire difficult to pool, but correlation is not itself a fat-tailed loss distribution. Define each mechanism separately.
