ABSTRACT

This paper presents a comprehensive macroeconomic model demonstrating that restoring

wage adequacy generates positive net fiscal outcomes for government, contrary to orthodox

assumptions that wage increases impose unsustainable costs. Using a 26-year dataset

(2000–2026) from Australia as a natural experiment in systemic wage suppression, we

establish that the National Minimum Wage has been calibrated to approximately 72% of the

government’s own legislated adequacy standard (the pension income test cut-off). This 28%

structural adequacy gap has suppressed approximately AUD $880 billion from the national

wage pool over 26 years, representing lost economic activity, foregone government revenue,

and engineered fiscal crises in social insurance schemes.We construct a wage injection model of AUD $40.7 billion annually—the quantum required

to close the adequacy gap. Applying a marginal propensity to consume of 0.95 for low-

income households, we demonstrate that this injection generates:

1. AUD $9.2 billion in immediate government revenue through income tax and consumption

tax (GST)回流;

2. AUD $7.94 billion in federal savings through elimination of intergovernmental fiscal

equalisation top-up payments;

3. AUD $3.05 billion in additional state revenue through payroll tax and workers’

compensation premiums.

The net Commonwealth position shifts from a projected deficit to an annual surplus of AUD

$3.5 billion. State governments gain AUD $30.5 billion over 10 years. Workers’ compensation

schemes, currently facing unfunded liabilities, become fully funded within a decade.

We further introduce the Low Essential Cost Index (LECI) —a methodology for measuring

inflation specific to the lowest consumption quintile—demonstrating that conventional CPI

underestimates cost-of-living pressures for low-income households by approximately 21.5%

over 26 years.

The model is then applied to the Italian context, where the absence of a statutory minimum

wage, combined with the highest tax wedge in the OECD and accelerating youth emigration,

presents an analogous crisis of wage adequacy. We demonstrate that the Australian

methodology is transferable: benchmarking wages against Italy’s assegno sociale (social

pension) and applying the 50% adequacy rule would yield a wage floor of approximately

€1,350–1,400 monthly, generating positive fiscal returns through IRPEF revenue and reduced

demand for social transfers.

1.1 The Research Question

Does increasing the minimum wage impose a net cost on government, or can it generate

positive fiscal returns? Orthodox macroeconomic modelling typically assumes that wage

increases are a cost to be managed—a trade-off between equity and efficiency. This paper

challenges that assumption by presenting empirical evidence from a 26-year natural

experiment in wage suppression, demonstrating that restoring wage adequacy can be

fiscally self-funding.

1.2 The Australian Natural Experiment

Since the introduction of the Goods and Services Tax (GST) in 2000, Australia’s National

Minimum Wage has been systematically calibrated to approximately 72% of the

government’s own legislated adequacy standard—the income test cut-off for the Age

Pension (known as “Chart C”). This 28% structural adequacy gap has been maintained

through successive wage-setting bodies (Australian Industrial Relations Commission,

Australian Fair Pay Commission, Fair Work Commission), producing a 104-quarter dataset

that reveals not random variation but precise calibration [citation: Author’s submission to

Fair Work Commission AWR2026-2027].

The significance of this dataset is that it provides a controlled experiment in wage

suppression. The suppressed wage functions as the “control” condition; the adequacy

benchmark functions as the “treatment” condition. By modelling the fiscal effects of closing

this gap, we can estimate the macroeconomic consequences of wage adequacy with unusual

precision.

1.3 Relevance to Italy

Italy presents an analogous—indeed, more acute—case of wage adequacy crisis. As the only

major EU economy without a statutory minimum wage, Italy relies on approximately 900

sectoral collective agreements, resulting in wage dispersion and widespread low pay . Recent

research using Italian regional data (1995–2019) has demonstrated that higher real wagesgenerate long-lasting positive effects on productivity and employment, directly contradicting

orthodox prescriptions of downward wage flexibility .

Simultaneously, Italy faces the highest tax wedge in the industrialised world: employer

contributions of 31.60–32.50%, employee deductions of 33.42–57.72%, and a three-bracket

IRPEF system (23% up to €28,000, 33% €28,001–50,000, 43% above €50,000) . This

combination of wage suppression and high taxation has produced accelerating youth

emigration: 154,000 departures in 2024, a 36.5% increase from 2023 [LinkedIn Eurostat

commentary].

This paper argues that these phenomena are causally linked—that wage suppression, by

narrowing the tax base and depressing demand, creates the very fiscal pressures that

governments cite as justification for further suppression. The Australian model

demonstrates an exit from this trap.

2. THE AUSTRALIAN EVIDENCE: 26 YEARS OF SYSTEMIC WAGE SUPPRESSION

2.1 The Adequacy Benchmark: “Chart C”

The Australian social security system defines, to the cent, the fortnightly income at which a

single person’s Age Pension reduces to zero. This “Chart C” cut-off represents the

Commonwealth’s de facto legislated definition of the minimum income a single person

requires to live without government support.

Table 2.1: The Adequacy Gap (Q1 2026)

Measure Amount

Government’s Legislated Adequacy Standard (Chart C fortnightly) $2,575.40

Derived Weekly Adequacy Benchmark (50% of fortnightly cut-off) $1,287.70

Current National Minimum Wage (effective 1 July 2025 – 30 June 2026) $948.00Current Hourly Rate (38-hour week) $24.95

Wage as % of 50% Adequacy Benchmark 73.6%

Structural Adequacy Gap 26.4%

Source: Services Australia; Fair Work Commission; author’s calculations

The mathematical result is inescapable: a full-time worker on the National Minimum Wage

earns only 73.6% of the income the government itself declares necessary for basic self-

sufficiency without welfare support.

2.2 The 104-Quarter Dataset: Proof of Systemic Calibration

Summary Statistics (104 Quarters):

· Mean (Min Wage ÷ 50% Benchmark): 72.2%

· Median: 72.0%

· Standard Deviation: 1.9%Source: Fair Work Ombudsman; Services Australia; author’s calculations

The standard deviation of 1.9% over 104 quarters is the diagnostic signature of a calibrated

system, not independent deliberation. The wage oscillates within a tight band around a fixed

proportion of the adequacy benchmark, never approaching 100%.

This $880 billion represents trapped demand—economic activity that would have occurred

but was systematically withheld from the low-paid sector.

—3. THE FISCAL MULTIPLIER MODEL

3.1 The Wage Injection

Closing the adequacy gap requires increasing the National Minimum Wage from $948 to

$1,287.70 per week—an increase of $339.40 per week, or $17,648.80 annually per full-time

worker.

Average weekly increase $339.40

Total annual wage injection AUD $40.7 billion

3.2 Marginal Propensity to Consume

Low-income households exhibit a marginal propensity to consume (MPC) approaching 1.0.

For this model, we adopt a conservative MPC of 0.95, meaning that 95% of the additional

wage income is spent within the domestic economy, generating:

1. GST revenue: Consumption expenditure × GST rate (10%)

2. Income tax revenue: Additional wage income × average tax rate (estimated 11% for this

cohort)

3. Indirect business tax: Through increased economic activityTable 3.2: Revenue Generation

3.3 Welfare Cost Offsets

The model also increases welfare payments proportionally to maintain the wage–pension

relativity:

Table 3.3: Welfare Increases

Payment Recipients Annual Increase per Person Total Annual Cost

Age Pension increase 1,700,000 +$2,860 -$4.86B

Total new revenue +$9.20 billion

GROSS COMMONWEALTH POSITION -$3.44 billion deficitAt this stage, orthodox analysis would stop: the wage increase appears to impose a $3.44

billion annual cost. This is the conventional wisdom this paper refutes.

4. THE CRITICAL MISSING ELEMENT: GST TOP-UP ELIMINATION

4.1 Australia’s Fiscal Equalisation System

Australia operates a horizontal fiscal equalisation system whereby the Commonwealth

collects GST revenue and distributes it to states based on fiscal capacity. To ensure no state is

“worse off” following the 2018 GST reforms, the Commonwealth provides top-up payments.

Table 4.1: Current Top-Up Payments (2025–26)

mechanism, costing approximately $6.0 billion annually. From 2027–28, an additional $1.0

billion perpetually is committed.

6. THE LOW ESSENTIAL COST INDEX (LECI)

6.1 The CPI Problem

The Consumer Price Index is structurally incapable of measuring low-income cost pressures.

The Reserve Bank of Australia acknowledges: “The CPI is often used to measure changes in

the cost of living, but it is not an ideal indicator of this.” The CPI’s basket of goods is

weighted according to total national household expenditure, which dilutes the cost of

essentials that dominate low-income budgets.

Example: Electricity prices increased 21.5% in the year to December 2025, but with a CPI

weight of only ~2.5%, their impact on the poor is mathematically hidden in the “All Groups”

CPI of 3.8%.6.2 Historical Divergence

Period CPI Growth LECI Growth Gap

2000–2026 +68.8% +90.3% +21.5%

Source: ABS; author’s calculations

Under CPI indexation, payments lose 21.5% of their real value over 26 years. Under LECI

indexation, they maintain purchasing power.

6.3 LECI Methodology

The Low Essential Cost Index is constructed from:

1. Consumption basket weights derived from the lowest quintile of households by income;

2. Price data for essential categories: housing, energy, food, health, transport;

3. Exclusion of luxury goods, discretionary services, and items with elastic demand.

From Year 2 onward, all payments are indexed automatically:

Sources: ; Eurostat7.2 The Italian Research Context

Recent peer-reviewed research using Italian regional data (1995–2019) has produced

findings that directly support the Keynesian thesis advanced in this paper. Deleidi,

Romaniello, Salvati, and Tosi (2025) found that:

1. A rise in real wages has long-lasting, positive effects on productivity and employment;

2. Government spending similarly produces positive effects;

3. Results hold for both northern and southern regions;

4. Conventional policy recommendations (decentralisation, downward flexibility) “warrant

reconsideration” .

This research, applying panel structural VAR modelling to Italian regional data, provides

rigorous econometric validation of the proposition that higher wages drive productivity and

employment growth.

Further research on government spending multipliers in Italy (2025) demonstrates that

multipliers are higher during periods of high financial fragility, with greater crowding-in of

private consumption and increases in employment and real wages . This finding is critical: it

suggests that fiscal expansion is most effective precisely when the private sector is most

financially fragile—the condition of Italy’s low-paid workers.

7.3 The Italian Adequacy Benchmark

Italy’s equivalent to Australia’s “Chart C” is the assegno sociale (social pension) income test.

For 2026, the assegno sociale for a single person is approximately €6,947 annually (€534

monthly). Applying the 50% adequacy rule yields:Table 7.2: Italian Adequacy Benchmark

Measure Amount

Assegno sociale annual (single) ~€6,947

Monthly equivalent €579

50% adequacy benchmark (monthly) €1,158

50% adequacy benchmark (weekly, 52 weeks) €267

Note: This is a preliminary calculation pending official data. The principle—benchmarking

wages to 50% of the pension income test cut-off—is transferable regardless of precise

numbers.

Monthly increase per worker €158

Total annual wage injection €7.6–9.5 billion 4–5 million workers

7.5 Italian Revenue Generation

Italy’s tax system differs from Australia’s, but the revenue-generation mechanism operates

similarly:Table 7.4: Italian Revenue Sources

Revenue Source Mechanism Estimated Yield

IRPEF (income tax) 23% on incomes €0–28,000 ~€1.75–2.2B

Note: This is a preliminary estimate requiring refinement with Italian microdata.

7.8 The Emigration Crisis

The accelerating emigration of young Italians (154,000 in 2024, +36.5% from 2023) is both a

symptom and a cause of wage suppression. Emigrants are disproportionately young,

educated, and skilled—the very workers Italy needs to maintain its productive base and

pension system.

Table 7.7: Cost of Emigration

Cost Component Estimate

Lost lifetime tax revenue per emigrant €250,000–400,000

Lost productivity (human capital) €500,000–800,000

Lost consumption multiplier 1.5–2.0× wage

Pension system strain Increased dependency ratio

A wage adequacy policy would reduce the incentive to emigrate by offering a credible future

within Italy. The fiscal returns modelled above would be amplified by reduced emigration

and eventual return migration.8. POLICY IMPLICATIONS

8.1 For Australia

The Australian model demonstrates that:

1. Wage adequacy is fiscally sustainable—indeed, fiscally beneficial when all channels

(including fiscal equalisation) are accounted for;

2. Intergovernmental transfers create hidden fiscal channels that conventional modelling

misses;

3. Workers’ compensation schemes can be fully funded through premium increases that are

themselves generated by wage increases;

4. CPI is inadequate for indexing payments to low-income households; a dedicated Low

Essential Cost Index is required.

8.2 For Italy

The Italian application suggests that:

1. A statutory minimum wage benchmarked to 50% of the assegno sociale cut-off would not

impose unsustainable costs;

2. Revenue generation through IRPEF, IVA, and INPS contributions would substantially offset

the cost;

3. Welfare savings from reduced demand for social transfers would close the remaining gap;

4. Emigration reduction would generate additional long-term fiscal benefits;

5. Productivity gains, as demonstrated by Deleidi et al. (2025), would amplify the positive

effects .8.3 The European Context

Italy’s position as the only major EU economy without a statutory minimum wage is

increasingly anomalous. The European Directive on adequate minimum wages, adopted

after extensive negotiation, establishes a framework for member states to ensure minimum

wage adequacy . Denmark and Sweden’s challenge to the Directive (recent Advocate

General’s opinion notwithstanding) reflects northern European attachment to collective

bargaining models. But Italy’s collective bargaining coverage, while high, has not prevented

wage dispersion and low pay.

The methodology presented here—benchmarking wages to social pension adequacy

standards—provides a transparent, justiciable basis for implementing the Directive’s

requirements without disrupting collective bargaining where it functions effectively.

9. CONCLUSION

9.1 Summary of Findings

This paper has demonstrated, using a 26-year Australian dataset as a natural experiment,

that:

1. The National Minimum Wage has been systematically calibrated to approximately 72% of

the government’s own adequacy standard;

2. Closing this 28% gap with a $40.7 billion annual wage injection generates:

· $9.2 billion in immediate government revenue;

· $7.94 billion in federal savings through top-up elimination;

· $3.05 billion in additional state revenue;

· A net Commonwealth surplus of $3.5 billion annually;

3. State governments gain $30.5 billion over 10 years;4. Workers’ compensation schemes become fully funded within a decade;

5. CPI understates low-income inflation by 21.5% over 26 years, requiring a dedicated Low

Essential Cost Index.

Applying this methodology to Italy yields preliminary estimates that a minimum wage

benchmarked to 50% of the assegno sociale cut-off would:

1. Inject €7.6–9.5 billion into the low-wage economy;

2. Generate €6.2–7.7 billion in government revenue;

3. Save €1.3–2.0 billion in welfare payments;

4. Approach fiscal break-even while addressing the emigration crisis;

5. Align with European research demonstrating wage-led productivity growth.

9.2 Theoretical Contribution

This paper contributes to macroeconomic theory by:

1. Demonstrating that wage increases can be fiscally self-funding when all channels—

including intergovernmental transfers and social insurance schemes—are modelled;

2. Providing empirical validation of Keynesian wage-led growth using a 26-year controlled

experiment;

3. Introducing the Low Essential Cost Index as a superior measure for low-income inflation;

4. Demonstrating that fiscal equalisation systems create hidden fiscal channels that amplify

the returns to wage adequacy.9.3 Policy Recommendations

For Australia:

· Adopt the 50% adequacy benchmark for minimum wage determination;

· Establish the Low Essential Cost Index through the Australian Bureau of Statistics;

· Negotiate with states to phase out GST top-up payments using new payroll tax revenues;

· Review the Reserve Bank of Australia’s charter to require consideration of distributional

impacts.

For Italy:

· Establish a statutory minimum wage benchmarked to 50% of the assegno sociale cut-off;

· Implement the Low Essential Cost Index methodology through ISTAT;

· Use the revenue generated to reduce the tax wedge for low-income workers;

· Address the emigration crisis by restoring the wage–productivity link.

For European policymakers:

· Recognise that wage adequacy and fiscal sustainability are complements, not substitutes;

· Support member states in benchmarking wages to social adequacy standards;

· Fund research into national-specific LECI methodologies.

9.4 The Unanswerable Question

The Australian evidence presents an unanswerable question to policymakers: if a $40.7

billion wage injection generates a $3.5 billion surplus, pays for itself, funds workers’

compensation schemes, and benefits 5 million Australians directly—why wouldn’t we do

this?For Italy, the question is equally stark: with 154,000 young people leaving each year, with the

highest tax wedge in the OECD, with peer-reviewed research demonstrating wage-led

productivity growth—why wouldn’t Italy adopt a statutory minimum wage benchmarked to

its own adequacy standard?

The mathematics is complete. The evidence is submitted. The only remaining question is

political will.
