Rule of law as institutional substrate — contract enforcement, judicial independence, equal treatment before the law. Upstream of most other axes.
Security of private property rights — formal recognition, expropriation risk, titling systems.
General government spending as share of GDP, excluding transfers already captured under fiscal.transfer_expansion to avoid double-counting.
Trade policy openness — tariffs, non-tariff barriers, FTAs, industrial protection.
The Pula Fund, established in 1994 and managed by the Bank of Botswana, is the country's long-term sovereign wealth fund holding the share of foreign exchange reserves judged surplus to short-term import-cover needs. Invested abroad in equities, fixed-income and alternatives under a conservative mandate set with the Ministry of Finance, it sterilises mineral inflows, smooths real-exchange-rate appreciation, and saves a portion of finite diamond rents for future generations within Botswana's broader fiscal-rule framework.
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.
