Singapore's post-2014 FTA expansion — covering CECA upgrade with India (in-force 2005, modernised post-2014), CPTPP 2018, RCEP 2022 — sustained the export-share-of-GDP and trade-openness ratios at the world's highest levels, with exports of goods and services / GDP averaging at least 170% over 2015-2019 (vs 100-130% for global peers like NLD, BEL, IRL), and Singapore's real GDP-pc growth maintaining at least +0.3pp/yr differential vs the high-income East Asian peer panel (KOR, JPN, HKG) over 2014-2019.
Falsification criterion — what would disprove this
This hypothesis is considered falsified if:
PRIMARY (dispositive, BOTH for SUPPORTED): (1) Singapore's exports/GDP averages at least 170% over 2015-2019; AND (2) SGP real GDP-pc growth minus high-income East Asian peer mean (KOR, JPN, HKG) over 2014-2019 is at least +0.003. REFUTED if EITHER fails.

- Claim: Singapore's post-2014 FTA expansion — covering CECA upgrade with India (in-force 2005, modernised post-2014), CPTPP 2018, RCEP 2022 — sustained the export-share-of-GDP and trade-openness ratios at the world's highest levels, with exports of goods and services / GDP averaging at least 170% over 2015-2019 (vs 100-130% for global peers like NLD, BEL, IRL), and Singapore's real GDP-pc growth maintaining at least +0.3pp/yr differential vs the high-income East Asian peer panel (KOR, JPN, HKG) over 2014-2019.
- Falsification rule: PRIMARY (dispositive, BOTH for SUPPORTED): (1) Singapore's exports/GDP averages at least 170% over 2015-2019; AND (2) SGP real GDP-pc growth minus high-income East Asian peer mean (KOR, JPN, HKG) over 2014-2019 is at least +0.003. REFUTED if EITHER fails.

Strongest opposing argument
Every hypothesis ships with its charitable opposing argument. The framework earns credibility by handling objections at their strongest, not weakest.
Notes
Tests Singapore's hyper-open trade model continuation post-2014. Trade openness threshold of 170% is calibrated to detect maintenance of frontier-trader status; growth differential vs Korea/Japan/HK benchmarks against high-income East Asian comparators.
