Each record describes something a country built that the indicators miss. The source provides the number; the mechanism is our interpretation.
Scores describe outcomes. These records describe how a country acted, what it needed and what happened. 44 of 44 records include a mechanism. They do not affect scores.
Brazil ended four decades of high inflation with a staged currency reform, taking annual consumer price inflation from 2,075.9 percent in 1994 to 3.2 percent in 1998.
3.2 % per year, annual consumer price inflation, 1998. World Bank, from IBGE, retrieved 2026-08-26.
The move, and what it needed
A stable unit of account was introduced alongside the failing currency, prices were re-anchored to it while it was still only a reference, and it became legal tender only once the anchoring had happened.
Preconditions
A technical team with authority to sequence the reform
Enough reserves to defend the new currency
Public exhaustion with inflation deep enough to accept the transition
Where it travelled: The staged unit-of-account move is the transferable idea and it has been studied everywhere. The exchange rate anchor that held it in place broke in 1999, which is the part not to copy.
Limits: Disinflation was held in place with an overvalued exchange rate and high interest rates, and that arrangement broke in the 1999 devaluation and again in the 2002 confidence crisis. One macroeconomic outcome is not a general measure of how fast Brazilian institutions respond to new conditions. The design and the sequencing are the capability here, and no number in this record captures them.
🇧🇷Brazilsince 1975still operatingbears on Institutional responsiveness
Brazil answered the 1973 oil shock by mandating ethanol blending and building a national fuel alcohol industry, taking production from 580 thousand cubic metres in 1975 to 38,199 in 2025, and from 2003 flex-fuel engines moved the choice to the driver.
A blending mandate created guaranteed demand, subsidised credit built the mills against it, and flex-fuel engines two decades later moved the choice from the state to the driver.
Preconditions
A crop and land base able to supply at scale
A state able to hold a mandate for decades
Domestic vehicle manufacturing that can be made to adapt
Where it travelled: The mandate-then-credit sequence is transferable and has been tried widely. The flex-fuel step is what made it durable and it required the car industry to move.
Limits: The programme was heavily subsidised in the 1980s and nearly collapsed when oil prices fell in the 1990s, so the line is not a story of steady success. Production volume says nothing about land use, cane labour conditions, or how the emissions accounting works out. What this evidences is a state changing an entire fuel system in response to an external shock, which is the construct the indicator asks for.
🇦🇷Argentinasince 1991dismantledbears on Institutional responsiveness
Argentina ended hyperinflation by fixing the peso to the dollar by law in April 1991, taking annual inflation from 4,923 percent in 1989 to 3.9 percent in 1994, and the regime held until it collapsed in the 2001-2002 crisis.
Congress fixed the exchange rate one-to-one to the dollar by statute and barred the central bank from printing unbacked pesos, which converted a monetary promise nobody believed into a law that was costly to break.
Preconditions
Dollar reserves large enough to back the monetary base
A legislature willing to bind itself and its successors
Prices and contracts already partly dollarised, so the anchor was credible on day one
Where it travelled: Currency boards were copied widely in the 1990s, from Estonia to Bulgaria, and they worked as stabilisers. Argentina is the case every copy now studies for the exit problem: the law had no honest way out.
Limits: The IMF and World Bank series for Argentina do not reach these years, so the numbers come from a teaching case that republishes the official table, and the 1989 figure is a December-to-December change where other publications give 3,079 percent as the annual average. Ending inflation is what the indicator asks for, but the fixed parity that delivered the stabilisation also removed the tools that could have absorbed the shocks of 1999-2001, so the case evidences a response that consumed its own durability. The collapse later cost Argentina its statistical credibility too, which is why the official series is hard to cite today.
Germany answered the 2008-2009 collapse in manufacturing orders by paying firms to cut hours instead of jobs, and short-time work covered 1.44 million workers at the May 2009 peak, about 5 percent of insured employment, while unemployment barely rose.
The employment agency reimburses firms most of the net wage for hours not worked when demand collapses, converting the existing unemployment-insurance fund into a payroll bridge, and the 2009 government lengthened the entitlement and cut the paperwork.
Preconditions
A standing legal instrument and fund, so scaling needed a regulation rather than a new law
Works councils and employers used to negotiating hours
A shock read as temporary, since the bridge only pays off if demand returns
Where it travelled: Short-time work schemes spread across the OECD after 2009 and nearly everywhere in 2020. The lesson that travelled worst is fiscal: the bridge is cheap only when the crisis is short.
Limits: The count says how many workers were covered, not what the scheme cost, how much of the covered work would have survived anyway, or whether it slowed reallocation to better firms, which are the standard criticisms. The instrument long predates 2008; what the episode evidences is the speed at which an existing legal instrument was expanded inside one year. The same instrument covered over six million people in 2020, so the 2009 number is not its ceiling.
🇹🇷Turkeysince 2001operating below its peakbears on Institutional responsiveness
Turkey answered its 2001 banking collapse with central bank independence, bank restructuring and fiscal rule, taking inflation from 54.4 percent in 2001 to 8.6 percent in 2004, and after 2018 the same framework was overridden until inflation reached 72.3 percent in 2022.
A crisis government handed monetary policy to an independent central bank by law, recapitalised and closed broken banks through an autonomous agency, and held a primary surplus, which together made the anti-inflation promise credible for fifteen years.
Preconditions
A crisis deep enough to make the political cost of reform payable
External anchors, the IMF programme and EU accession prospect, that rewarded holding the framework
A technocratic team with authority to execute across ministries
Where it travelled: The package was the standard post-crisis prescription and worked as designed. What the case adds is the second half: formal independence survived on paper while governors were replaced until policy followed the executive, a path other countries have since repeated.
Limits: Inflation is an outcome with many causes: the 2001-2004 fall also rode an IMF programme and a global disinflation, and the post-2018 rise includes a currency crisis and imported energy prices, so neither number isolates the institutions. The record runs both ways by design: the same state that built a working stabilisation framework later demonstrated that the framework had no defence against its own executive. The institutions were not abolished, which is why the status is eroded rather than dismantled.
🇧🇷Brazilsince 1972delivered and closedbears on Institutional responsiveness
Created in 1972, Telebras coordinated Brazil's state telecom system until its 1998 privatisation, when 54 concessionaires were split out and the state moved from operating the network to regulating and universalising service.
The state first assembled a fragmented telecom sector into one planning and investment system, then dismantled that holding structure when a new regulatory and private operating model was judged more suitable for expansion.
Preconditions
Authority to consolidate regional operators under one national plan
A public investment and research base large enough to build the network
A legal and regulatory framework able to transfer operating assets without abandoning the public objective
Limits: The number of controlled companies shows the structure of the old system, not whether privatisation delivered affordable, reliable service everywhere. The transition also left a continuing Telebras with a different role, so the record concerns a model that ended rather than a company that disappeared.
