Pre-registration
Vietnam's Doi Moi 1986 reforms and subsequent export-oriented strategy replicated the East Asian developmental-state pattern and produced three decades of above-peer-region growth.
Falsification criterion — what would disprove this
This hypothesis is considered falsified if:
PRIMARY (dispositive): SUPPORTED if the cumulative log-GDP-per-capita gap (Vietnam minus equal-weighted SE-Asian donor-pool counterfactual) by 2010 exceeds +0.25 log-points (~+28% in levels), where the donor pool is {PHL, IDN, KHM, LAO, BGD, MMR} and the index is anchored at the first year all panel members have WDI NY.GDP.PCAP.PP.KD coverage (typically 1990, since WDI VNM PPP coverage begins then). REFUTED if the gap is <= 0 (Vietnam at or below equal-weight donor mean). PARTIAL if 0 < gap < +0.25. INFORMATIVE: post-2000 mean gaps in (i) manufacturing-value-added/GDP share (NV.IND.MANF.ZS) and (ii) exports/GDP share (NE.EXP.GNFS.ZS) vs the same donor pool; PWT rtfpna log-change vs donors over common years. METHOD_VALID: at least 3 of the 6 donors must have WDI GDP-pc-PPP data at the base year, and at least 10 overlapping VNM/donor-pool years base-to-2010, else the verdict is `inconclusive (method_valid)`.

Vietnam treated post-1986; donor pool of comparable Southeast Asian economies (PHL, IDN, MMR, KHM, LAO, BGD) with similar 1986 income. Outcome: real GDP per capita and manufacturing-export share. Tests whether Doi Moi reforms produced above-counterfactual growth.

Detailed result card
Vietnam Doi Moi developmental pattern — growth effect
Verdict: SUPPORTED — Vietnam log-GDP-per-capita ran +0.34 log-points (≈ +40%) above the equal-weighted SE-Asian donor pool (PHL, IDN, KHM, LAO, BGD, MMR) by 2010, base year 1990. Threshold was +0.25 log-points; cleared by +0.09. Long-window gap to 2019: +0.33 log-points (≈ +39%).
Summary
Equal-weighted SE-Asian donor-pool counterfactual for Vietnam's post-Doi-Moi GDP-per-capita PPP. Vietnam treated in 1986; data effectively begins 1990 (WDI VNM coverage). Donor pool (at base year): PHL, IDN, KHM, LAO, BGD, MMR.
- Primary log-gap by 2010: +0.34 log-points (≈ +40% in levels) vs threshold +0.25.
- Long-window gap to 2019: +0.33 log-points (≈ +39% in levels).
- VNM log-index at 2010: +1.08; donor mean: +0.75.
- Overlap years base→2010: 21 (need ≥10).
Informative metrics
- mfg_value_added_pct_gdp: data gap (missing series).
- exports_pct_gdp: data gap (missing series).
- PWT TFP: not available on this vintage.
Method
- Treatment: Vietnam, year ≥ 1986 (Doi Moi).
- Donor pool: PHL, IDN, KHM, LAO, BGD, MMR (Southeast-Asian peers with comparable 1986 income, excluding the East Asian Tigers THA/MYS which are reference comparators rather than donors).
- Counterfactual: equal-weighted mean of donor pool log-GDP-pc-PPP, anchored to the first overlapping year (typically 1990 for WDI). No optimisation of donor weights — equal-weighting is a conservative baseline because it includes KHM/LAO/MMR which had their own catch-up booms post-1990; a true synth-DiD weight optimiser would likely down-weight these and INCREASE the gap.
- Primary statistic: cumulative log-GDP-pc gap (VNM minus donor-mean) at 2010.
- Dispositive threshold: +0.25 log-points (≈ +28% in levels). The spec asked for >+25%, rendered in log-space here.
- Method validity gates: ≥3 donors with data at base year, ≥10 overlap years base→2010.
Caveats
- WDI's NY.GDP.PCAP.PP.KD coverage for VNM begins 1990, not 1986. The script anchors the index at the first overlapping year (1990 in current vintage). Pre-Doi-Moi macro data for VNM is sparse and not in WDI on the PPP basis — synth-DiD pre-trend matching in the strict sense is not feasible without alternate sources.
- Equal-weighted donor-pool counterfactual is NOT a true synth-DiD weight optimisation. v2 should run a proper synth with pre-1986 covariate matching where data permits, or fall back to PPP from PWT (which has earlier coverage).
- Donor pool excludes THA/MYS (East Asian Tiger / NIE peers). If those were included, the counterfactual would be higher and the Vietnam gap would be smaller. v2 robustness check.
- Author's market-liberal priors interpret Vietnam's success as primarily about market opening, not state-led pattern replication; this could under-weight industrial-policy evidence.

Notes
Stub seeded from a developmentalist school prediction about Vietnam's post-1986 trajectory. Pre-Doi-Moi macro data is sparse; needs human review of donor-pool comparability with regional peers.
