Abenomics' combined monetary-fiscal expansion lifted Japanese inflation and output partially but failed to durably escape the deflation equilibrium, consistent with NK models of near-permanent ZLB traps.

Nigeria's May 2023 elimination of the petrol subsidy under President Tinubu produced a fiscally favourable but socially costly trajectory: federally-retained revenue rose, the primary fiscal balance improved relative to the 2018-2022 baseline, but headline CPI inflation accelerated and household real-consumption proxies weakened in the 12-24 months post-removal.

Argentina has experienced 12 distinct episodes of annual inflation exceeding 50% since 1945, each preceded by a fiscal deficit exceeding 4% of GDP financed via central bank money creation.

From 2000 to 2023, Asian economies that continued market-oriented institutional reform from a low starting GDP-per-capita base — China, India, Vietnam, Indonesia, Malaysia, Thailand, Philippines, Bangladesh, Sri Lanka, Cambodia — converged rapidly on Western income levels, with cumulative log GDP-per-capita-PPP growth materially greater than incumbent Western economies.

Post-2010 European fiscal consolidation intensity negatively predicts subsequent output-gap closure speed and cumulative output over the 2010-2019 window, with the effect concentrated in the Eurozone periphery where the combination of sovereign spreads, no monetary- policy-at-country-level, and high initial output gaps produced a multiplier larger than the pre-crisis consensus assumed.

High seigniorage financing of government spending predicts lower private financial-deepening ratios and weaker long-run investment.

Prolonged zero-lower-bound policy predicts rising pension-fund underfunding and higher contribution demands on younger workers relative to retired beneficiaries.

Italy's 2016-2017 banking-distress episode — Banca Monte dei Paschi di Siena precautionary recapitalisation in July 2017, Veneto-banks resolution in June 2017, and a peak system-wide non-performing-loan ratio above 17% — represents a protracted-NPL-overhang post-GFC banking distress case that did NOT meet the canonical full-systemic-banking-crisis threshold but DID require multiple state-aid resolution events.

The 1945-1973 Bretton Woods era sustained higher trend growth and lower unemployment across OECD than the post-1973 floating-rate era because capital-account controls preserved fiscal space for demand management.

El Salvador's fiscal trajectory under Bukele (2019-2024) shows improvement in the primary balance and stabilisation (or modest decline) in debt-to-GDP after the 2020 COVID spike, achieved via a combination of: (a) the 2022-2023 bond buyback / liability-management operations, (b) the 2023 tax reform (lower rates with base-broadening and improved compliance), and (c) IMF-signalled fiscal consolidation culminating in the Dec 2024 $1.4bn Extended Fund Facility.

Canadian GDP per capita (PPP, constant international dollars) diverged negatively from a donor pool of resource-plus-advanced-anglophone-plus- small-open-developed economies (USA, AUS, NZL, GBR, NOR, CHE) starting around 2015, such that the Canadian per-capita trajectory 2015-2023 is materially below a country-and-year-fixed-effect counterfactual matched on pre-2015 level and covariates.

Higher capital-gains tax rates predict lower firm-entry rates, fewer IPOs, and slower venture-capital formation.

Revenue-neutral carbon taxes (with offsetting payroll or income tax cuts) predict lower emissions without net employment loss compared to cap-and-trade with grandfathering.

Deng Xiaoping's 1978 reforms, by introducing price signals and household responsibility in agriculture and Township-Village-Enterprise market exchange, account for the majority of Chinese poverty reduction 1978–2000 — not state investment.

China's 1978 Deng-era reforms — Household Responsibility System in agriculture, Special Economic Zones, dual-track price liberalisation, Township and Village Enterprise reform, gradual opening to FDI and trade — produced a structural break in per-capita GDP growth rates.

China's local-government-financing-vehicle (LGFV) debt expansion 2015-2024 — driven by post-2015 credit easing, infrastructure stimulus to offset property weakness, and 2020-2022 COVID fiscal response — produced a structural rise in non-financial-corporate debt-to-GDP and a generalised public-sector debt-to-GDP increase that is observable in BIS credit aggregates and IMF general-government debt series.

Lower statutory corporate tax rates predict higher business investment and faster capital deepening, with larger effects in open economies.

Germany's Schuldenbremse (constitutional debt brake, 2009) produced lower debt-to-GDP trajectories than comparable-economy fiscal-rule-absent peers over 2009–2019, without output loss relative to the Eurozone mean.

Across OECD countries 1990-2023, the rise in the old-age dependency ratio is associated with a proportional increase in public pension expenditure as a share of GDP and crowding-out of productive public investment, particularly where pay-as-you-go pension architecture predominates.

Post-1990 (and especially post-EU-accession 2004/2007) outmigration from Eastern Europe (POL, ROU, BGR, LTU, LVA, EST, HUN, SVK) has produced upward pressure on real wages at origin via labour-supply contraction.

Across OECD countries 1995-2023, the tertiary-education wage premium (median wage of tertiary-attainment workers / median wage of upper-secondary workers) varies substantially cross-country, and is positively associated with rate of skill-biased technical change proxies (ICT capital share).

Italy and Spain 1995-2023 exhibit a coupled demographic-growth stagnation: sustained sub-replacement fertility (TFR ~1.2-1.4) since the 1980s feeds into post-2008 working-age contraction, which decomposes as a substantial share of the post-2008 per-capita growth shortfall vs the EU-15 median.

Mexico's fertility decline (TFR 6.7 in 1970 to ~1.8 in 2023) is associated with a working- age share rise that should have translated into rising real wages 1995-2023, partially offset by US migration outflows.

Across high-income destination countries 1995-2023, migration inflows have heterogeneous wage effects by skill: high-skill (tertiary-educated) inflows are associated with neutral or positive wage effects on natives, while low-skill inflows produce small negative wage effects on the bottom decile of native earners but no aggregate native-wage decline.

The UK's decision not to apply transitional restrictions on A8 (2004) accession-state migration produced a large inflow (~1.5 million by 2014), particularly Polish-origin.

The strongest long-run economic performers among countries that achieved middle-income status are those that used developmentalist tools (state-directed credit, sectoral targeting, export subsidies, infrastructure investment) for catch-up growth, then transitioned toward market competition, fiscal discipline, and rule-bound institutions before reaching frontier convergence.

Erhard's 1948 currency reform and price-control removal produced the fastest recovery in post-war Europe, demonstrating that rules-based market restoration outperforms Bretton-Woods-era rationed economies.

Euro-area Southern members (Greece, Italy, Spain) post-2010 suffered larger output contractions than fiscal-space-preserving peers because Maastricht-constrained fiscal policy combined with ECB pre-2015 tightness produced contractionary conditions New Keynesian models predict at the currency-union ZLB.

Post-2008 eurozone austerity disproportionately affected households in the bottom income quintile; distributional cost was not necessary for fiscal consolidation, given alternative tax-side options.

US Sanders 2016/2020 $15 federal minimum wage proposal, in meta-analyses of state-level evidence, would not produce the 1.3m-job loss CBO low-end estimate; effect is closer to zero.

Financial-transaction taxes predict lower market liquidity, higher volatility, and reduced price-discovery efficiency.

Credible fiscal consolidation episodes — defined as sustained primary balance improvement of at least 2% of GDP over 3 years, not reversed within 5 years, and accompanied by declining debt-to-GDP trajectories — predict stronger subsequent 10-year real GDP per capita growth and private investment than repeated discretionary fiscal stimulus in mature economies, in an OECD panel 1980-2020.

Japan post-1990 has run gross public-debt-to-GDP ratios from ~70% rising to ~250%, the highest sustained level in the OECD record, WITHOUT triggering inflation, currency collapse, sovereign-spread blowout, or fiscal-dominance-induced loss of monetary control.

Fiscal multipliers are state-dependent: large at ZLB, small near full employment; no single-number answer is policy-relevant.

Fiscal multipliers are substantially larger at the zero lower bound than in normal interest-rate regimes, because crowding-out via higher rates is suppressed.

Higher fiscal-transparency indices predict lower sovereign bond-yield spreads and smaller default-risk premia at given debt levels.

Since 1973, US nonfarm-business labour productivity has cumulatively outpaced real hourly compensation by a large margin, indicating a persistent productivity-compensation divergence.

US free-community-college state experiments (Tennessee Promise 2015, Oregon 2016) raised enrolment and completion rates among low-income students without measurable fiscal crowd-out.

Rapid market liberalisation (price decontrol, mass privatisation, trade opening) under weak institutions produces large short-run welfare losses—rising mortality, falling life expectancy, rising inequality, and collapsing output—that may persist for at least a decade, compared to gradual reformers or non-reformers at similar initial income levels.

Germany's Schuldenbremse (constitutional debt brake adopted 2009 and binding on the federation from 2016) did not produce a sustained growth or investment collapse over 2010-2019 (pre-COVID) at the single-country time-series level.

Following Koo (2008, 2014), the post-2008 advanced-economy recovery exhibited the diagnostic pattern of a balance-sheet recession: the private sector (households especially, plus non-financial business in the most leveraged countries) shifted simultaneously from net borrowing to net saving in pursuit of debt reduction, even when policy interest rates were at the zero lower bound.

The 2007-2009 global financial crisis originated in household-debt-financed consumption sustaining aggregate demand despite stagnant real wages, a Minsky-plus-Marx pattern.

Higher government-consumption shares predict weaker TFP growth after controlling for public investment, education, and health spending, across a broad panel of advanced and emerging economies from 1970 to 2020.

In a broad-country panel 1980-2019, a larger government expenditure share of GDP predicts lower subsequent total-factor-productivity (TFP) growth, controlling for initial income, trade openness, and human capital.

Haiti's 2010-2024 governance trajectory — the failed post-earthquake reconstruction (2010-2015), Martelly-era PetroCaribe-fund mismanagement (2011-2016), Moïse assassination (July 2021), gang takeover of Port- au-Prince (2022-2024), and effective state collapse — produced a catastrophic economic collapse measurable in real-GDP-per-capita decline, life-expectancy stagnation, and emigration acceleration.

Health-savings-account or catastrophic-plus-savings designs contain cost growth without worse age-adjusted mortality than comprehensive public-insurance peers.

High-income-country per-capita material footprint (UNEP International Resource Panel "raw material equivalents" consumption-based metric) has not declined materially over 2000-2022 -- mean change across the high-income panel is within +/-10% of 2000 levels -- despite a documented decline in territorial CO2 emissions over the same window.

Within Anglo-liberal economies (UK, US, Australia) over 1995-2020, housing-supply-restricted high-opportunity metro areas exhibit real-wage-net-of-housing-cost trajectories that diverge substantially from their headline real-wage trajectories, such that the standard "real wage stagnation" story for these metros is amplified (larger stagnation) when housing costs are properly netted out, while housing-supply-elastic metros show the opposite pattern — headline real-wage stagnation looks less severe after housing is netted.

Industrial policy (sectoral targeting, export subsidies, conditional credit, technology push) succeeds in raising long-run manufacturing productivity and export sophistication when implemented in high-governance states with export discipline (clear performance criteria, sunset clauses, competitive benchmarking), over 30-year windows 1960-2020.

The 2021-2024 Eurozone inflation episode is best decomposed as a cost-push / distributional-conflict process rather than a demand-pull / monetary-overhang process: profit-margin expansion in energy, food, and tradable-goods sectors accounts for at least 40% of cumulative GDP-deflator growth 2021Q1-2023Q4 per the ECB and IMF unit-labour-cost decomposition framework, wage growth lagged price growth across the entire 2021-2023 window with real wages declining in every Eurozone economy, and the inflation moderation in 2024 is driven by terms-of-trade reversal rather than wage-side moderation.

Informal employment as a share of total non-agricultural employment persists at higher levels in countries with high entry barriers and burdensome product-market regulation (high OECD PMR, high Doing Business cost of starting a business), even when the state invests heavily in development projects and public infrastructure.

Higher inheritance taxes predict more frequent sale or liquidation of family businesses at founder death and lower long-run business survival.

Across liberal democracies, the country's general-government spending share at the start of the corpus window negatively predicts subsequent statist drift.

Italy's real GDP per capita (PPP, constant international dollars) was approximately unchanged between 1999 (euro launch) and 2023 — a quarter-century of near-zero cumulative growth, with modest levels of variation around a flat trend.

Japanese public debt crossing 150%, then 200%, then 250% of GDP 1990-2020 did not trigger a solvency or inflation crisis, contradicting household-debt-analogue framings.

Japan crossed every debt-to-GDP threshold predicted by Sargent-Wallace (1981) "unpleasant monetarist arithmetic" framing — 100% (1996), 150% (2002), 200% (2010), 250% (2020) — without producing the predicted outcomes: 10y JGB yields fell rather than rose across the full 1990-2024 window, CPI inflation averaged below 1% over 1995-2020 and did not breach 4% even at the 2022-2024 global price shock peak, and no sovereign-debt distress event occurred.

Japanese stagnation 1990-2020 (mean GDP growth under 1%) coincided with stable or improving wellbeing indicators (life expectancy, life satisfaction), refuting the claim that zero-growth necessarily degrades human outcomes.

Elevated US JOLTS job openings are a leading indicator of broad private-sector wage growth; when job openings accelerate, average hourly earnings growth follows within six months.

Higher market-compatible regulatory quality predicts stronger long-run real wage and income proxies.

Blanchard-Summers hysteresis: prolonged high unemployment (European NAIRU rise post-1980s, post-2008 Southern Europe) produces persistent labour-force detachment and skill decay that raises the natural rate.

Argentina's 2017 Macri-government labour-reform package (Vaca Muerta sector-specific reform, broader labour-cost reduction proposal partially blocked) failed to deliver a measurable formal-employment gain by 2019: synthetic-DiD gap on formal-employment share is statistically indistinguishable from zero against a Latin-American donor pool, falsifying the strong-pro-employment claim.

France's 1998-2002 35-hour week law (Aubry I 1998, Aubry II 2000) did not produce the predicted +700,000 net jobs claimed by proponents; the synthetic-DiD gap on French employment rate 2000-2005 vs euro-area peers is below +1.0 pp and statistically indistinguishable from zero, while real wage growth slowed measurably.

Spain's February 2012 labour reform (Real Decreto-Ley 3/2012: dismissal-cost reduction from 45 to 33 days/year, decentralised collective bargaining, "objective causes" expansion) shortened the duration of the post-2011 unemployment surge by accelerating hiring rates 2014-2017 by at least 1.5 pp relative to a synthetic control of euro-area peripheral peers, without producing a permanent reduction in real wages relative to donors.

Stricter land-use regulation proxies predict weaker real disposable wage and income gains via housing costs.

Brazil's Novo Arcabouço Fiscal (Lei Complementar 200 of 2023) holds the federal primary-balance path and the real-spending growth rate within its statutory band (real primary spending growth 0.6-2.5% per year, conditional on primary-balance target attainment) through 2026, and the cumulative 2023-2026 primary- balance outcome does not diverge from target by more than one standard deviation of the historical primary-balance forecast error.

Maastricht convergence criteria 1992 imposed fiscal discipline that produced lower inflation and interest-rate convergence in pre-accession EU members, consistent with the Ordoliberal principle of rules-binding monetary constitutions.

Higher share of mandatory vs discretionary spending predicts stronger automatic stabilisers and less pro-cyclical fiscal policy.

Across a pre-registered panel of OECD and major emerging-market economies from 1996 to 2023, larger government expenditure shares predict lower employment rates after country and year fixed effects and basic macro controls.

Market-compatible regulatory quality predicts stronger job-quality proxies measured by employment and income levels.

Milei's "motosierra" (chainsaw) programme combines public-sector employment cuts, ministry consolidation (from 18 to 9 ministries), and elimination of energy/transport subsidies.

Argentine monthly CPI inflation declines from its late-2023 peak (around 25% month-on-month in December 2023 following the 54% peso devaluation) to below 5% month-on-month within 12 months of Milei's December 2023 inauguration, and below 3% month-on- month within 18 months.

Argentine quarterly real GDP, having contracted in 2024H1 under the Milei stabilisation shock, recovers along a trajectory that by Q4 2025 closes at least 50% of the peak-to-trough output gap observed during the shock's worst quarter, and by Q4 2026 returns to or exceeds the pre-Milei (Q4 2023) real-GDP level.

Milei shock therapy in Argentina from December 2023 produces poverty-rate increase and real-wage decline in its first two years (2024-2025) of magnitude consistent with the Marxist-Leninist critique of neoliberal restoration — distinct from the inflation-stabilisation and output-recovery questions handled by separate hypotheses.

Minimum-wage increases above the local median-wage ratio produce disemployment effects at the low-skill margin, even if aggregate employment effects are small.

Across the 2008-2014 ZLB era and the 2020-2021 pandemic-response window, large-scale de-facto monetary finance of fiscal expansion in the US, Japan, and the Eurozone did not produce headline-CPI inflation consistent with naive quantity-theoretic monetisation predictions: cumulative central-bank balance-sheet expansion exceeded 15% of GDP while CPI YoY remained below 3% in each economy across both windows.

Nordic persistent outcome advantages (GDP per capita, Gini disposable income, unemployment) over comparable high-welfare Southern European economies over 1996-2023 are substantially explained by a decomposable set of institutional, market-economy, and fiscal-discipline features — specifically government effectiveness, rule of law, and debt-to-GDP ratio — rather than by welfare architecture or Nordic-specific cultural factors alone.

The v1 decomposition (three channels: WGI gov effectiveness, WGI rule of law, IMF debt/GDP) left 98% of the Nordic-vs-Southern-Europe log GDP/capita gap unexplained.

Norway's post-1990 GPFG resource-rent architecture outperformed a hydrocarbon-dependent donor pool on real GDP per capita, consistent with the claim that collective ownership of resource rents plus market-based management can avoid resource-curse growth outcomes.

Higher tax burden proxies predict lower labour-force participation over long windows.

The US COVID labour-market shock 2020-2024 produced a sharp asymmetric reallocation — leisure/hospitality and brick-and-mortar retail collapsed in 2020 then over-recovered nominal wages relative to trend, while professional/information sectors saw remote-work entrenchment with persistently elevated WFH share and lower CBD office utilisation through 2024.

Agricultural output surges most sharply in years following price liberalisation and de-collectivisation, controlling for weather.

US labour productivity and median compensation grew together 1945-1973 but decoupled after 1973, and the decoupling magnitude exceeds what composition-adjusted measures eliminate.

Higher top marginal income-tax rates predict lower taxable income reporting among high earners (behavioural response) and larger tax-avoidance industries.

Higher reliance on property taxes for local government predicts stronger taxpayer accountability and better public-service quality than transfer-dependent localities.

Larger unfunded public-pension liabilities predict lower domestic investment and higher implicit debt burdens that crowd out productive spending.

Public investment in basic infrastructure (transport, energy, water, sanitation) has strong catch-up returns to real GDP per capita growth in developing and emerging economies, while persistent public transfers and subsidies have weaker or insignificant long-run growth effects, in a broad-country panel 1980-2020.

Post-2008 large-scale asset purchase programmes by the Federal Reserve, ECB, Bank of England, and Bank of Japan produced a measurable divergence between asset-price inflation (equities and residential real estate) and headline consumer-price inflation until roughly 2021.

Post-2008 quantitative easing operated principally through a Minsky-style financialisation channel — collateral-revaluation, portfolio-rebalancing into long-duration risk assets, and a yield-driven compression of risk premia — rather than through the textbook quantity-theoretic broad-money or expectations channels.

Fed QE programmes 2008–2014 lowered long-end yields and corporate spreads, raising asset prices and stimulating investment through portfolio-rebalancing and signalling channels even at the zero lower bound.

Rogernomics (NZ) and Pinochet-era Chile produced positive macro outcomes because reforms were combined with strengthened institutions; same reforms without institutional strengthening (Russia 1990s) produced catastrophic outcomes.

Tobacco and alcohol taxes with elastic demand generate health gains but unstable revenue; inelastic-demand sin taxes generate stable revenue but smaller behavioural change.

The Soviet central-planning system, having already exhibited TFP stagnation 1970-1989, underwent a canonical institutional and economic collapse 1989-1998 as plan-enforcement was withdrawn without functioning market institutions in place.

Across the OECD 38, over 2000-latest, larger general government final consumption as a share of GDP is associated with slower growth in real household disposable income per capita, controlling for demographics, initial-income level, energy-price exposure, and trade openness.

Strong employment-protection legislation (EPL) with high union wage-setting coverage and limited at-will dismissal produces a three-order causal chain in Southern European labour markets.

Automatic indexation of tax brackets to inflation prevents real tax burden increases and supports labour-supply growth.

Countries with broader tax bases and lower marginal rates show stronger long-run investment and GDP growth than countries with narrow bases and high rates.

At high-income levels (GDP per capita above OECD median), very high tax burdens — defined as total tax revenue above 40% of GDP — predict weaker long-run total factor productivity growth unless paired with unusually high state capacity (top tercile WGI Government Effectiveness) and high labour- market flexibility (top tercile OECD EPL), in an OECD and high-income panel 1980-2020.

International tax competition for mobile capital predicts lower corporate rates but does not reduce total corporate revenue when bases are broad.

Higher broad tax-burden proxies predict lower control-of-corruption and trust-related governance outcomes.

More tax exemptions and special regimes predict higher compliance costs, larger avoidance sectors, and lower effective progressivity.

Greek Memorandum-era tax hikes 2010-2018 (top marginal income rate raised to 45 percent, VAT hikes to 24 percent standard, ENFIA recurring property tax 2014, solidarity surcharge 2011-2019) raised the disposable-income Gini coefficient by at least 1.5 Gini-points relative to Eurozone- comparator synthetic control over the period, with the regressivity driven by VAT and property-tax incidence rather than income-tax progressivity.

Post-apartheid South African tax structure (top marginal income rate raised to 45 percent in 2017, capital-gains inclusion ratio raised 2012 + 2016, recurring property-tax effective burden via municipal rates) produced a measurable reduction in the South African top-1 pretax income share over 1995-2024 vs SADC synthetic comparator pool, with the recurring property-tax channel contributing more than the marginal-income-rate channel to the distributional effect.

Higher broad tax burden proxies predict slower disposable-income and consumption growth.

Simpler tax systems — measured by fewer tax payments per year, lower time spent on tax compliance, and fewer separate taxes — predict higher entrepreneurship rates (new business registrations per 1,000 working-age adults) and stronger small-firm employment growth over 20-year windows, in a broad-country panel 2000-2020.

Tax simplification (fewer filings, flat rates, presumptive thresholds) predicts faster small-firm employment growth and higher formalisation.

Broader tax-treaty networks predict higher bilateral FDI flows and stronger productivity spillovers to domestic suppliers.

Egypt's FTA cascade (EU Association Agreement 2004, Agadir Agreement 2007, COMESA Free Trade Area 1998 with full implementation 2009, US Qualifying Industrial Zones 2004 enabling duty-free apparel exports to the US under Israeli content rules) raised Egyptian trade-openness modestly over 2000-2010 before the 2011 revolution and subsequent macroeconomic instability eroded the gains.

The EU's 2007 (BGR, ROU) and 2013 (HRV) enlargements produced a smaller per-capita-income convergence acceleration than the 2004 enlargement, because (a) accession occurred into the financial- crisis and post-crisis austerity environment rather than the pre-crisis growth boom, and (b) baseline institutional quality was lower at the accession date.

Large expansions of means-tested or categorical transfers without work- incentives or activation requirements predict lower prime-age labour-force participation rates over 15-20-year windows relative to expansions that incorporate negative-income-tax or earned-income-tax-credit designs, in an OECD and rich-country panel 1980-2020.

The September 2022 UK gilt-market dysfunction had its operative amplification mechanism in the foreign-currency-collateral exposure of the Liability-Driven Investment (LDI) leveraged-derivative chain in the UK pension system, not in a "fiscal limit" reached by the sovereign issuer.

The 2016 Brexit referendum shock produced a clear near-term UK inflation pass-through and a squeeze in CPI-deflated weekly earnings over the 2016Q2-2017Q4 event window.

UK Cameron-Osborne austerity 2010-2016 reduced output below the counterfactual path and failed to reduce the debt-to-GDP ratio on the government's own timeline.

UK GDP per capita (PPP, constant international dollars) diverged negatively from a matched synthetic counterfactual of similar-income anglophone/developed economies (USA, CAN, AUS, NZL, DEU, NLD, CHE) starting around 2008 and widening post-2016 (Brexit referendum).

The 2022 UK energy-price shock produced high CPIH inflation and a material CPI-deflated weekly-earnings squeeze.

UK Truss mini-budget 2022 gilt crisis reflected market confidence and institutional-framework rupture rather than an MMT-predicted hard fiscal limit, because the BoE restored order by intervening as issuer.

Truss 2022 mini-budget shows that unfunded fiscal expansion above the ZLB triggers sharp bond-market and currency responses through expected-inflation and risk-premium channels.

Large-scale universal or near-universal transfer programmes produce a three-order causal chain.

Child-poverty rates in EU countries with universal child-benefit systems are substantially lower than in means-tested systems at similar tax-and-transfer cost.

Uruguay's 2005-2020 Frente Amplio era (Vázquez I, Mujica, Vázquez II) expanded the welfare state (Plan de Equidad 2008, Asignaciones Familiares expansion, FONASA universal-health integration 2008, Sistema Nacional Integrado de Cuidados 2015), legalised cannabis 2013, and ran a centre-left fiscal-and-redistributive programme without abandoning macroeconomic orthodoxy.

Pre-2008 US household debt expansion sustained aggregate demand in the face of stagnant real median wages, a pattern inconsistent with representative-agent rational-expectations models.

The observed gap between US median real wage growth and US real GDP per capita growth over 1973-2000 (commonly characterised as "wage stagnation during a productivity boom") is substantially explained by a decomposable set of channels rather than a single rent-extraction story: (a) growth in non-wage benefits — primarily employer-paid healthcare — substituting for cash wages; (b) compositional shifts in the labour force driven by expanded female labour force participation lowering the median worker's experience profile; (c) divergence between consumer-price and output- price deflators (Feldstein measurement critique); (d) the genuine but smaller residual of top-strata capture of marginal product growth (Bivens-Mishel reading).

US post-2008 recovery shows rising GDP per capita alongside stagnant or declining median-household ISEW/GPI indicators, consistent with Daly's diminishing-returns-to-growth.

Higher VAT efficiency (revenue/product of standard rate and consumption base) predicts stronger public-finance sustainability and lower debt drift.

In the 2021-2024 OECD inflation episode, wage growth lagged price inflation rather than led it — average across OECD economies, real wages fell 2-4% cumulative 2021-2023 before recovering — refuting the wage-price-spiral framing and supporting the "profit-led-then-supply-shock-driven" decomposition (Bivens, Weber, Stiglitz) for the early phase, with wage catch-up only emerging 2023-2024 once inflation peaked.

Large electricity-access expansion from 1990 to 2023 should generally coincide with positive average real GDP-per-capita growth rather than being bought at the price of stagnation.

High-remittance economies should usually avoid extreme average current-account deficits over 2000-2023 because worker transfers directly finance external balances.

Wealth taxes predict capital flight, lower reported domestic wealth, and reduced investment, especially when valuation is subjective and enforcement uneven.

Forced-saving welfare architectures (Singapore CPF since 1955, Chile AFP since 1981, Australia Superannuation Guarantee since 1992) and universal-transfer architectures (Nordic model, UK NHS) produce different profiles on two dimensions: (a) retirement-income adequacy for the median retiree, and (b) long-run fiscal sustainability as measured by projected net liabilities of the pension / welfare state over 30+ year horizons.

Mexico's 2023 Pensión Universal expansion (DOF January 2023, raising the universal-noncontributory pension to all adults 65+ at twice the previous level under AMLO's constitutional amendment) raised social-spending share of GDP by at least 1 percentage point of GDP within two fiscal years, with no offsetting domestic-revenue measure, generating a measurable structural-fiscal-balance deterioration visible in IMF Article IV monitoring and BdM stability reports.

Large welfare states sustain long-run real GDP per capita growth when paired with market flexibility (low product- and labour-market barriers), trade openness, and fiscal discipline (debt-to-GDP below 90%), but not when paired with rigid product and labour markets, in an OECD and rich- country panel 1980-2020.

Brazil's Bolsa Família phase-2 (post-2010 expansion under Dilma 2011-2015 with Brasil Sem Miséria add-on, then Bolsonaro-era restructuring 2019-2021, then Lula-era Auxílio Brasil to BFP rebrand 2023) produced diminishing marginal poverty-reduction returns relative to the 2003-2010 phase, with the post-2014 commodity-bust eroding the wage-floor channel that complemented BFP transfers in phase-1, illustrating cash-transfer-program-decoupling from labour-market complement.

China's combined social-protection expansion — urban dibao (1999, expanded 2003) plus rural dibao (2007 universalisation) plus rural-pension scheme NRPS (2009 launch reaching 459M+ enrollees by 2013) — reduced rural extreme-poverty headcount by at least 5 percentage points within five years (2009-2014) net of growth-channel effects, identified off province-staggered NRPS rollout 2009-2012 and province-level dibao-spending intensity in panel-FE design.

France's RSA (Revenu de Solidarité Active 2009, replacing RMI + API) and Prime d'Activité (2016, replacing RSA-activité + PPE) lowered the participation tax rate on low-wage work and raised employment among low-education beneficiaries by 2 to 4 percentage points relative to a synthetic-control donor pool of EU peers without comparable reforms (BEL, ITA, ESP, PRT) over five-year post-reform windows.

Indonesia's PKH (Program Keluarga Harapan, conditional cash transfer launched 2007 with phased expansion to 10M+ households by 2018) and BLT/BLSM unconditional energy-subsidy compensation transfers (2005, 2008, 2013, 2014, 2022) produced complementary poverty effects, with PKH delivering long-horizon human-capital channel and BLT delivering short-horizon consumption-smoothing channel, identified off staggered PKH rollout cohorts and BLT one-shot event-windows in the panel of Indonesian provinces 2005-2022.

Kenya's Hunger Safety Net Programme (HSNP, scaled-up from 2013 pilot to full-arm coverage in four northern arid-land counties 2015, with shock-responsive scale-up triggered by NDMA drought-monitor thresholds 2017 and 2022) demonstrably smoothed consumption among recipient households during drought episodes by at least 15 percentage points relative to non-recipient households in eligibility-cliff comparison areas, providing causal evidence that mobile-money-delivered shock-responsive transfers outperform conventional emergency-aid in ASAL contexts.

Portugal's 2010-2012 austerity-era rollback of the Rendimento Social de Inserção (RSI) — eligibility restrictions, value freezes, and stricter conditionality under the Troika programme — raised severe material deprivation among working-age households by at least 3 percentage points within 4 years, identified off the synthetic-control gap with Greece-excluded southern-EU donor pool, demonstrating that residualisation of guaranteed-minimum-income programmes during fiscal consolidation has measurable poverty cost.

South Africa's social-grants system (Old Age Pension extension 1998, Child Support Grant 1998-2012 expansion to age 18, Disability and Foster Care Grants, Social Relief of Distress 2020-2024) reaching 18+ million recipients — roughly 30% of population — has produced sustained reductions in extreme- poverty headcount of 6 to 10 percentage points relative to a synthetic-control of upper-middle-income Sub-Saharan and LatAm peers without comparable grant-coverage scale, while exerting fiscal-pressure costs visible in National Treasury MTBPS structural-balance projections.

Across OECD economies 1995-2021, the cumulative fiscal multiplier on real output at the zero lower bound (defined as quarters with policy rate ≤ 0.50% AND inflation expectations anchored below 2.5%) exceeds 1.2 at horizon h=8 quarters, while the comparable normal-regime multiplier is below 0.7.
