Introduction
Each July, the wages of the lowest paid workers in Australia move. The Fair Work Commission’s Annual Wage Review 2024-25 lifted the National Minimum Wage by 3.5 per cent to $24.95 per hour, a decision that flowed through every modern award and adjusted the pay of roughly 2.9 million employees (Fair Work Commission 2025). Every review revives the oldest empirical dispute in labour economics. Employer associations warn that mandated pay rises will price the least productive workers out of work; unions reply that the predicted job losses never seem to arrive. This essay argues that the second camp has the better of the evidence: moderate, regular minimum wage increases of the kind delivered through the Australian award system have not caused economically significant job losses, and the pattern of near-zero employment effects is better explained by imperfect competition in low-wage labour markets than by the competitive textbook model. The claim is deliberately conditional, applying to increases within the range Australia has actually experienced. The essay sets out the institutional context and the rival theories, weighs the international and Australian evidence, examines the youth and small business channels and the inflation-era reviews, then confronts the strongest counterargument.
The Institutional Setting: Wage Floors in the Australian System
Australia does not have a single wage floor so much as a lattice of them. Beneath the National Minimum Wage sit the classification rates of more than one hundred modern awards, and it is these rates, not the headline minimum, that anchor pay across the low-wage labour market. More than one in five Australian employees are paid exactly the award rate for their classification, with award reliance concentrated in accommodation and food services and retail trade (ABS 2023). The Fair Work Commission adjusts this entire structure once a year under the minimum wages objective of the Fair Work Act 2009 (Cth), which obliges its expert panel to balance the needs of the low paid and relative living standards against business competitiveness and employment growth. Two features matter for the employment question. First, the Australian floor bites hard: the adult minimum sits at roughly 55 per cent of the median wage, among the highest ratios in the OECD and close to double the United States figure (Dube 2019). If minimum wages destroyed jobs on the scale the competitive model implies, Australia is where the damage should be easiest to see. Second, adjustment is annual, moderate and predictable, unlike the episodic, sometimes large increases studied in the American literature, giving employers time to plan rather than a shock to absorb.
Competing Theoretical Predictions
The competitive model generates the familiar prediction. If the labour market clears at a wage below the legislated floor, the floor operates as a price control: employment falls along the labour demand curve, and the workers rationed out are those furthest below the new minimum in productivity, disproportionately the young and inexperienced. On this view the only open questions are the size of the demand elasticity and the identity of the losers; that there are losers is settled by theory itself.
That certainty dissolves once perfect competition is relaxed. Manning (2003) formalised what everyday observation suggests: employers of low-wage labour hold wage-setting power because job search is costly, workers value location and hours as well as pay, and quitting is slow and risky. An employer facing an upward-sloping labour supply curve maximises profit by paying a wage below the marginal revenue product of labour, tolerating persistent vacancies. In that setting a minimum wage set between the monopsony wage and marginal revenue product raises pay without reducing employment, and can raise employment by drawing more workers into the market. Monopsony therefore predicts exactly the pattern the competitive model forbids: small, zero or even positive employment effects for moderate increases, turning negative only once the floor overshoots productivity.
The models also differ on where adjustment appears. Even with headcount unchanged, firms can respond through prices, rostered hours, lower staff turnover, higher work intensity and compressed margins, and the empirical literature finds these channels do most of the work (Dube 2019). Which model describes actual low-wage labour markets cannot be settled by theory; it is the central empirical question.
The International Evidence
The modern empirical literature begins with Card and Krueger (1994), who surveyed fast food restaurants on either side of the New Jersey and Pennsylvania border before and after New Jersey raised its state minimum in 1992. Employment in the affected stores did not fall relative to the comparison group, a result flatly inconsistent with the competitive prediction. The study was immediately contested: re-estimation using payroll records reported negative effects (Neumark & Wascher 2000). Its enduring contribution was methodological: credible inference requires a comparison group, and the quasi-experimental designs it inaugurated now dominate the field.
Three decades of accumulation have since produced something close to consensus on the central tendency. Cengiz et al. (2019) examined 138 state-level minimum wage increases in the United States between 1979 and 2016 by tracing the distribution of jobs by wage rate: jobs just below each new minimum disappeared, an almost identical number appeared just above it, and the net employment effect was statistically indistinguishable from zero for up to five years. Meta-analysis points the same way. Doucouliagos and Stanley (2009), synthesising 1,474 published estimates, showed that the apparent negative average effect in the literature reflects publication selection bias; once corrected, the residual employment effect is close to zero. Reviewing the evidence for the United Kingdom Treasury, Dube (2019) concluded that employment effects of minimums up to around 60 per cent of the median wage are muted, a finding that underwrote the escalation of the British National Living Wage and that carries particular weight for Australia, whose floor sits near the same relative height.
The Australian Evidence
Direct Australian evidence is thinner, because a national floor that moves uniformly offers little of the cross-sectional variation on which quasi-experimental designs feed. Leigh (2003) exploited a period in which Western Australia adjusted its state minimum out of step with the rest of the country and reported small negative effects, although data limitations and a later published correction reduced the weight those estimates can bear. Surveying the field a decade later, the Productivity Commission (2015) concluded that modest adverse effects on hours or employment could not be ruled out, but found no evidence that Australian minimum wage adjustments had produced substantial job losses, and recommended retaining the annual review system.
The most credible Australian study remains Bishop (2018), published by the Reserve Bank of Australia. Exploiting variation across jobs in the size and timing of award wage adjustments, Bishop found that award increases were passed through almost fully into hourly wages yet had no statistically discernible effect on hours worked or on the probability that a job was destroyed. The caveats are as instructive as the result: the estimates cover the modest annual adjustments typical of Australian practice, cannot speak to effects on new hiring, and do not license extrapolation to much larger increases. Within its domain, however, the study aligns the Australian evidence squarely with the international null.
The period since 2022 supplies a demanding, if imperfect, out-of-sample test. The Commission awarded increases of 5.2 per cent in 2022 and 5.75 per cent in 2023, the largest in decades, yet unemployment remained between roughly 3.5 and 4.3 per cent, near five-decade lows, and employment continued to grow (Fair Work Commission 2025). Post-pandemic labour demand was unusually strong, so this experience cannot prove the increases cost nothing; it is nonetheless very difficult to reconcile with the proposition that large award rises mechanically destroy jobs.
Youth Employment and the Small Business Channel
If disemployment exists anywhere, theory locates it among the young. Teenagers and young adults are over-represented at the wage floor, and the international evidence for negative effects has always been strongest for teenagers (Neumark & Wascher 2000). Here institutional design matters. Australian awards prescribe junior rates that scale the adult minimum down steeply by age, from around half the adult rate at sixteen rising each year to the full rate at twenty-one, alongside discounted apprentice and trainee wages. These scales rebuild, inside the award system, the wage-productivity alignment whose absence drives the competitive model’s youth prediction, muting the most plausible channel of harm. Australian youth unemployment, at more than double the aggregate rate, tracks the economic cycle far more visibly than it tracks wage review decisions, with no structural break discernible around even the large 2022 and 2023 adjustments (Fair Work Commission 2025). The honest qualification is that hours are a live margin: casual rosters in retail and hospitality can be trimmed quietly, and Australian evidence on youth hours remains thin.
Small business is the second channel, and the political centre of every wage review. Award-reliant employment is concentrated precisely where margins are thinnest, in cafes, restaurants, accommodation and small retail (ABS 2023), and employers in those sectors cannot absorb cost increases through profits alone. The evidence indicates that they largely do not adjust by dismissing staff. Bishop (2018) found no effect on job destruction; the margins that matter empirically are modest price pass-through and reduced staff turnover as the gap to alternative jobs narrows (Dube 2019). The Productivity Commission (2015) likewise identified no systematic link between annual award adjustments and small business failure. None of this makes wage decisions costless for a marginal cafe in a weak trading year; it does mean the aggregate small business employment effect has not been shown to be negative.
Wage Setting in an Inflationary Period
The inflationary episode of 2022 and 2023 posed the sternest recent test of the review architecture. Headline inflation peaked at 7.8 per cent in the December quarter of 2022 and the real value of award wages fell sharply. The Commission faced a genuine dilemma: full indexation risked feeding a wage-price spiral, while restraint would entrench real income losses for the workers least able to bear them. The Australian Government (2023) submitted that protecting the real wages of the low paid was compatible with disinflation because award-reliant workers account for a modest share of the national wage bill, and the Commission steered a middle course, awarding 5.75 per cent in 2023 before stepping down to 3.75 per cent in 2024 and 3.5 per cent in 2025 as price pressures eased (Fair Work Commission 2025).
The outcome vindicated that judgement on both fronts. Inflation returned to the Reserve Bank’s 2 to 3 per cent target band by 2025 without a wages breakout, and the labour market in the award-reliant industries did not deteriorate. The episode illustrates a broader point: an expert tribunal that recalibrates annually, on published evidence and argument from employers, unions and government, functions as an institutional shock absorber. It can deliver large nominal increases when real wages are collapsing, and slow the pace when conditions warrant, as in 2020 when operative dates were deferred for the industries hardest hit by public health restrictions.
Counterargument and Rebuttal
The strongest counterargument accepts the evidence but disputes its reach, on three grounds. First, external validity: the celebrated null results are mostly American, generated where the minimum bites at barely 30 per cent of the median, whereas Australia’s floor, near 55 per cent, may sit close to the turning point at which even the monopsony model predicts losses. Second, measurement: if firms respond not by dismissing incumbents but by slowing hiring and letting vacancies lapse, studies of employment stocks will record nothing while job growth quietly erodes, the pattern Meer and West (2016) find in employment dynamics. Third, the recent Australian macro experience is confounded: record-low unemployment owed much to post-pandemic demand, and absorbing large increases in a tight labour market says little about a slack one.
Each objection narrows the claim; none overturns it. On bite, the most relevant evidence is no longer American: the British National Living Wage was escalated towards two-thirds of the median on the strength of Dube’s (2019) review without detectable employment loss at relativities comparable to Australia’s, and Bishop (2018) is Australian evidence generated at the Australian bite. Cross-country comparisons of headline ratios also ignore Australia’s built-in safety valves: junior, apprentice and supported wage scales mean the effective floor confronting the marginal employer of a teenager is far below the adult rate, and the annual review can slow its own pace. On dynamics, hiring-flow effects deserve monitoring, but after three decades in which predicted losses have repeatedly failed to materialise, the burden of proof now rests with the competitive model’s defenders. The confounding objection is conceded, and it is precisely why the position defended here is conditional: the evidence licenses moderate annual increases administered by an institution that watches the data, not wage setting by aspiration. Within the range Australia has actually traversed, the employment cost is approximately zero and the gains to low-paid households are real; beyond that range the evidence runs out, and so should confidence.
Conclusion
Do minimum wage increases cost jobs? On the evidence, not at the scale and in the manner Australia actually practises them. The competitive model’s clean prediction has repeatedly failed its empirical audition: in the American quasi-experimental literature, in bias-corrected meta-analysis, in the British escalation experience and, most pertinently, in Bishop’s Australian award study and in a labour market that absorbed the largest award increases in decades at near-record employment. The pattern is coherent rather than anomalous. Low-wage labour markets are pervasively monopsonistic, and firms adjust through prices, hours, turnover and margins long before they destroy jobs. The conclusion remains disciplined by its conditions: Australia’s null result rests on moderate, annual, institutionally mediated adjustment, cushioned by junior and training rates, and it does not underwrite increases of a different order. The Fair Work Commission’s architecture is not incidental to the finding; it is the mechanism that keeps Australia inside the range where wage justice and full employment coexist. The evidence supports keeping it, and continuing to use it.
