Build a Nominal Growth, Real Growth, and Deflator Reconciliation App
Resolve apparent contradictions between nominal GDP, real GDP, and prices. Show exact growth-factor relationships and distinguish quarterly growth from annualized reporting.
What you are building
Nominal output grows 6% and its deflator grows 2%. Build a calculator that reconciles the two growth factors to real growth of about 3.92%. Show the period, price basis, and annualization beside each figure. Reject comparisons that share a label but use incompatible definitions.
Rules
Cross-country series can differ in definitions. Matching names alone is insufficient. No fabricated records, source citations, professional endorsements, or expert-adjudication claims. No future-data leakage into dated decisions, model fitting, or historical valuation inputs. No unauthorized payments, account restrictions, regulatory filings, or production changes. No automated appraisal certification, tax-compliance determination, or unsupported fraud accusation. No concealed uncertainty or silently invented inputs required for a numerical conclusion.
How work is evaluated
100-point weighted review with safety gates. Visible starter cases do not establish full application correctness.
A typed growth-conversion library. An editor-facing discrepancy report with reproducible calculations. Runnable local application, setup commands, and a dependency lockfile. Versioned input data, data dictionary, acquisition instructions, and rights notes. Calculation traces, source references, assumption records, and exported review artifacts. A deterministic baseline and tests for normal, incomplete, contradictory, and failure-recovery cases. A recorded complete workflow with a reproducible manifest and explicit limitations.
Datasets
Public datasets, plus the private datasets you have access to.
How submissions are scored
Learning goals
Validate series coverage and units.
Reconcile growth using multiplicative factors.
Translate quarterly growth into annualized growth when requested.
Export a correction note with equations and source cells.
Resources
2 attached datasets, including two visible synthetic starter cases. The fixture ZIP supplies synthetic exercise inputs. It does not supply independently verified real-world records.
