Hypotheses¶
Testable predictions for Sourcing under Sanctions: Judicial Urgency and
Pharmaceutical Procurement Costs. Each hypothesis lives in its own file and is
referenced project-internally by H:<slug>.
Hypotheses are organized into four thematic clusters aligned with the canonical
manuscript v10-causal-mechanism/manuscript/paper/main.tex.
How to read a hypothesis page¶
Each page follows the same structure — the design → what's known → what's left:
- Title + lede: the
H:<slug>title, then a plain-words statement of the claim. - Evidence-strength callout: an at-a-glance verdict (Very strong / Strong / Moderate / Weak / Not yet tested) plus a one-line status.
- Theory: the theoretical motivation, with references.
- Prediction: the precise directional claim.
- Competing prediction: what a non-sourcing explanation predicts instead — the alternative the test has to rule out (typically an incumbent same-firm markup).
- Setting evidence: institutional and descriptive grounding from the
BEC-SP record and the
paper.mdsetting. - Empirical test: the concrete specification — outcome, variation, fixed effects.
- Data requirements and limitations: datasets needed and threats to identification.
- Evidence: a table of the project's analyses bearing on the hypothesis —
Analysis(AN-ID, linked) ·Bearing(Supports / Against / Mixed / Pending) ·Key takeaway. - Open tests: forward-looking only — analyses not yet run.
The scorecard below rolls up the current status of every hypothesis against
the analyses (AN-NNN) that bear on it.
Cluster A: The urgent-procurement margin (motivation)¶
Maps to paper §5.1 and to docs/results.md. Establishes the procurement environment — urgency raises costs and weakens competition — before the design moves inside urgent procurement.
- H:urgent-costlier-less-competitive — Urgent procurement is costlier and less competitive than ordinary procurement.
Cluster B: The sanction-related gap and same-firm pricing¶
Maps to paper §5.2–§5.3 and §4 (Empirical Framework). The selection-bounded under-the-gun contrast and the within firm-buyer-item pricing test that separates same-firm pricing from supplier-set sourcing.
- H:utg-gap-selection-bounded — Court-mandated urgent purchases cost more than the closest administrative urgent comparison, and the gap survives selection bounding.
- H:no-broad-same-firm-markup — In deep repeated urgent markets, the sanction-related cost margin does not appear as a broad same-firm markup.
- H:thin-market-supplier-leverage — The deep-market null is not universal: a residual within-firm gap persists in the earlier period (the quantity dimension reflects scale).
Cluster C: The sourcing mechanism¶
Maps to paper §5.4 and to docs/results.md. Where the procurement-cost margin operates: lost scale and supplier-set reallocation.
- H:lost-scale — Court-mandated buying gives up scale; administrative urgent orders are larger and capture bulk discounts.
- H:supplier-set-reallocation — Legal urgency reallocates the winning supplier set.
Cluster D: Identification and robustness¶
Maps to paper §6 (Falsification and Robustness) and to docs/robustness.md + docs/advanced.md.
- H:placebo-and-dynamics — The urgent-procurement pattern is specific to litigated items; dynamic evidence is diagnostic, not the primary design.

| # | Prediction | Intuition | Evidence | Status |
|---|---|---|---|---|
| H1 | Urgent procurement → higher prices and fewer bidders than ordinary | Compressed urgent sourcing cannot wait for aggregation or regular competition | AN-001 negotiated price +5.4%, reference price +2.7%, bidders −5.4%, tender success +2.1pp (item+year+PBU FE, PBU-clustered). All four outcomes significant and consistent in direction; establishes the motivational urgent-procurement margin, not the sanction-exposure design | Partial (strongly supported) |
| H2 | Litigated urgent > administrative urgent, gap survives selection bounding | One-sided sanctions raise the cost of court-mandated buying relative to the closest feasible urgent comparison | AN-002 naive 29.5%, Lee bounds 15.9%–21.1% after trimming the selected administrative group; AN-007 wild-cluster \(p=0.0080\) (preferred), 0.0390 (item-by-year-month) | Partial (strongly supported) |
| H3 | No broad same-firm markup in deep repeated urgent markets | Conditional on the same firm, buyer, and item, price is indistinguishable across urgent regimes | AN-003 within firm-buyer-item coefficient 0.035 (SE 0.041); near zero in above-median quantity (−0.005) and SUS-formulary (−0.001) subsamples | Partial (strongly supported) |
| H4 | The deep-market null is not universal: a within-firm gap persists in thin/early cells | Thin or early urgent pools could give incumbents room to price | AN-003 below-median quantity +0.066***, earlier period +0.117***, non-formulary +0.101; AN-004. Disambiguation: quantity axis is scale (within-FBI log-qty −0.259, 61); earlier-period gap survives a quantity control (+0.168, \(p=0.007\), 62) but is administrative-dearer and time-declining |
Partial (strongly supported) |
| H5 | Court-mandated buying gives up scale | Fragmented urgent buying forgoes bulk discounts | AN-005 quantity/scale component −32.8% of the gap, administrative orders 3.3× larger, bulk-discount elasticity −0.329; AN-009 aggregation diagnostic (mixed) | Partial (strongly supported) |
| H6 | Legal urgency reallocates the winning supplier set | Compressed timelines and fragmented demand change which supplier wins | AN-006 among 2,134 item-buyer pairs, modal winner differs in 70.2%, mean winner-set Jaccard similarity 0.268, 48.5% with no winner overlap | Partial (strongly supported) |
| H7 | Pattern is litigation-specific; dynamics are diagnostic | A generic platform/time-trend story would reproduce the pattern off the litigation margin; dynamic trends are sensitive | AN-008 never-litigated placebo −0.020 (SE 0.032), null; AN-013 matched buyer-class placebo −0.046 (SE 0.053), null; AN-010 BJS event study diagnostic, Honest-DiD does not survive at the observed maximum pre-period scale | Partial (strongly supported) |
