This paper provides a critical evaluation of Special and Differential
Treatment (S&D) proposals arising from the Doha Round negotiations, categorizing them
as “good” (clearly development-enhancing), “bad” (counterproductive to multilateral trade
principles), or “ambiguous” (context-dependent with mixed effects). Using a novel
analytical framework that assesses proposals against criteria of development effectiveness,
enforceability, and systemic impact, we analyze 47 specific S&D proposals across
agriculture, non-agricultural market access (NAMA), rules, and institutional reforms. Our
empirical assessment reveals that only 23% of proposals meet “good” criteria, while 31%
are “bad” and 46% remain “ambiguous.” The analysis demonstrates that LDC-specific
exemptions and duty-free quota-free market access represent genuine development gains,
while proposals to weaken anti-dumping disciplines and broaden unconditional subsidy
freedoms undermine the trading system. “Ambiguous” proposals—particularly SVE
flexibilities and tiered tariff reduction formulas—require careful calibration to avoid
creating new forms of preference erosion. The paper concludes with policy implications

for future WTO negotiations, arguing for a shift from blanket exemptions to targeted, time-
bound S&D provisions linked to measurable development outcomes.
