The Spatial Investment Lab asks where a fixed incentive budget should go and how much employment would be additional. Its Asheville example combines 2023 Census primary-job counts with a directed OpenStreetMap road network and Cesium terrain.
Visitors vary the subsidy per offered job, site additionality, within-area relocation, job persistence and discount rate. The accounting distinguishes supported offers, induced site employment and additional study-area jobs. A constrained allocation model compares equal shares with an access-maximizing allocation across six existing employment clusters, with an adjustable weight on lower-earnings workers and a concentration cap.
The 3D layers show existing employment, changes in potential job access and budget allocation. Distributional results, sensitivity tables, source hashes and scenario exports expose the assumptions behind the display. Independent original-graph routing checks and conservation tests accompany the model.
This is a conditional policy prototype. Behavioral parameters are illustrative; the model does not estimate causal incentive effects, incentive eligibility, land availability, wage effects, fiscal returns or general-equilibrium growth. The study window limits job destinations and residential weights.
The national investment atlas adds the FY2025 public CDFI release: 8,439 projects and $71.019 billion in QLICI financing, reconciled to 21,202 transactions. State and tract views, origination-year filters and exports describe observed financing; they do not estimate economic effects. This atlas uses a later vintage than the NMTC working paper.
