Trade policy openness — tariffs, non-tariff barriers, FTAs, industrial protection.
First phase of tariff reform announced February 1990 under Barco, designed by Planning chief Ernesto Samper and Hommes (later Gaviria's Hacienda minister). Reduced average nominal tariff from ~54% (1989) to ~40% (1990) and consolidated rate categories; eliminated some non-tariff barriers. Intended as a five-year gradual opening; Gaviria administration accelerated dramatically after August 1990.
Per invariant 3, reforms are scored by what they did on each channel-separated axis, not by the party that enacted them. This fingerprint is how the policy-match engine finds historical analogues.
Explicit links are curated by the author. Inferred links are hypotheses in the library that test the same axes this policy moved — the framework's answer to "what does the data say about a policy like this?".
Ranked by axis-fingerprint overlap with this policy. Direction match bolded — those are the closest historical analogues. Shape of the match is what drives policy-outcome comparison, not the country or party label.
