Research / Public data

Real wages & payroll budgets

Real hourly earnings rose 2.1% from February 2020, but fell 0.7% in the latest twelve months. Hours and inflation explain why the comparison period matters.

Interactive workbench

Operations / Public + assumptions

Diesel budget risk

A historical reserve covered 20 of 26 quarters. A fixed 10% buffer covered 24. The comparison makes the cost of a smaller reserve visible.

Interactive workbench

Finance / Simulation

Pricing & margins

Higher prices did not offset rising costs in this simulated customer portfolio. A margin bridge explains the $157,706 decline in contribution.

Analytical report

Finance / Simulation

Acquisition economics

A simulated incentive increased conversion, but its estimated value per prospect fell. The case separates acquisition growth from risk-adjusted economics.

Analytical report

Operations / Public + assumptions

Grid capital allocation

A constrained investment model selects three hypothetical upgrades. It also shows why a plan that survives the chosen scenarios can still fail a harsher stress.

Analytical report

Operations / Simulation

Appointment access

The simulated scheduling policy meets both booking targets, but reduces modeled contribution. Better access comes with a staffing tradeoff.

Analytical report

Forecasting / Public data

Rental demand planning

The selected model reduces historical test error from 18.70% to 13.35%. A separate planning model tests what those errors could cost.

Analytical report

Research / Public data

Utility reliability

Twenty-six state summaries fail reconciliation in the 2025 release. The workbench keeps that release out of its decision inputs.

Interactive workbench

Operations / Public data

Airline delay screening

A fixed shortlist captures more eligible peer-excess delay than a raw-burden ranking. It prioritizes investigation rather than claiming an intervention effect.

Interactive workbench

Finance / Public data

Bank deposit costs

Quarterly deposit interest expense falls by $5.01 billion across 4,018 screened banks. The bridge separates balances, mix and a derived rate measure.

Interactive workbench

Finance / Public data

Insurance reserve challenge

A modest change to the assumed claims-development tail adds $17.12 billion to the modeled unpaid balance. The gap warrants investigation, not a reserve release.

Interactive workbench

Finance / Public + assumptions

REIT refinancing

Thirty-seven of ninety financing scenarios fail the assumed cash floors even with full debt rollover. The model exposes the conditions behind that result.

Interactive workbench

Forecasting / Public data

Inventory forecast governance

The ridge model performs worse than the last disclosed inventory balance. The simpler baseline remains the default.

Interactive workbench

Finance / Public data

Rail reinvestment & returns

Three railroads distribute more than FY2025 operating cash less reported cash capex. The $665 million subtotal is a prompt for treasury review, not proof of a funding deficit.

Interactive workbench

Finance / Public + assumptions

Land option diligence

A contract register separates deposits already at risk from conditional future purchases. The option scenarios show why those are different decisions.

Interactive workbench

Finance / Public data

Hotel reimbursement economics

Reimbursements make up much of the selected operators’ reported revenue. Adjusting the denominator changes the apparent margin comparison.

Interactive workbench

Research / Public data

Houston mortgage pricing

Only 41.38% of eligible loans at the five selected lenders enter the common-support comparison. The analysis makes that restriction visible before comparing prices.

Interactive workbench

Finance / Public + assumptions

Retirement obligations

The disclosures support a reconciled liability ledger, but do not identify the full cash payment schedule. Timing assumptions produce a range rather than a forecast.

Interactive workbench

Research / Public data

Recession signal audit

Credit spreads improve one model comparison but lose to a simple historical probability. The candidate is not approved for use.

Interactive workbench

Finance / Public + assumptions

Restaurant operating leverage

Thirty-two assumed earnings stresses remain infeasible within the modeled response caps. The model also avoids deducting rent twice.

Interactive workbench

Finance / Public + assumptions

Working capital & liquidity

The illustrative Apple case releases cash, but its first-year financing benefit does not cover the assumed implementation cost.
