Data and software

Policy scenarios and trade shocks shouldn't be held hostage by local toolchains, hand-maintained directories, and scripts that can't be reproduced. EconMOD folds regional/sectoral aggregation, closure and shock specification, and general-equilibrium solving into a single auditable, collaborative server-side workflow. Why it matters In applied CGE / GTAP work, the real bottleneck is rarely "we can't write the equations" — it's: Dimension governance — from the global base data to an interpretable region-by-sector mapping, every step has to be checkable; Scenario engineering — closures (Book / Short / Long / Self) and shock variables must be aligned before submission, not guessed at after the solve fails; Compute and collaboration — the heavy lifting should queue and run on a server, with results deposited in structured form, not scattered across personal disks as intermediate files; Numerical credibility — key gates (aggregation accuracy, reference-scenario welfare EV, etc.) must be repeatedly verifiable by the team. EconMOD is built for exactly this chain — not another dashboard, but a runnable modeling workbench.

Partial-equilibrium models have long included forestry, but global general-equilibrium models with detailed forestry accounts remain scarce. We constructed a global GE database with a disaggregated forestry sector.
