  1. Overview
  2. Model laboratory

Model laboratory

The appraisal behind the recommendation, and the tools used to test whether it holds.
Model output

Everything on these pages is a model output. Nothing here is an observation of the Iraqi housing market, and no figure should be quoted as one.

Comparison

  • Mechanism comparison

    Fifteen candidate designs appraised on one assumption register, ranked on identical terms.

  • Robustness

    Whether the ranking survives changes in weighting, and where each result breaks even.

  • Scenarios

    Seventeen stress runs, including the ones where the mechanism fails.

Inputs

  • Assumption register

    Every parameter, its provenance, and the digest that identifies this version of the register.

  • Tender readings

    Five interpretations of using an entitlement in a bid, and what each costs in misallocation.

Challenge

  • Independent reconstruction

    A separately built model, retained because it disagrees with the first on points that matter.
