Minimum Wage in a Tight Labour Market with Public Funding Constraints
The adult minimum wage rises from $22.70 to $23.15 per hour, a 2.0% increase, at a time when unemployment is 3.6%, job ads have fallen 18% year-on-year, and annual CPI inflation is 4.0%. Roughly 80,000-100,000 workers are paid at or just above the minimum, concentrated in hospitality, retail, and aged care. Aged care providers, who are substantially publicly funded through Te Whatu Ora contracts, report that a 2% wage increase adds about $110 million per year to costs and that contract funding has not been indexed. Hospitality firms report net margins of 3-5%, and a survey suggests 40% would respond by reducing hours or raising prices. Immigration settings have recently tightened, reducing the working-holiday and essential-skills inflows that previously filled entry-level roles.
1. Compare the competitive labour market and monopsony models in predicting the employment effects of this minimum wage increase in aged care. Which model better fits the evidence described?

Competitive model. The labour market clears at wage w* where supply equals demand. A minimum wage above w* creates excess supply: employment falls, some workers gain, others lose jobs. The size of the employment loss depends on the elasticities of labour demand and supply. In aged care, demand for labour is relatively inelastic in the short run because residents need care, so employment loss may be small.
Monopsony model. If there are few employers in a local labour market (for example, one aged-care provider in a town), the employer faces an upward-sloping labour supply and sets employment where marginal cost of labour equals marginal revenue product. The resulting wage is below the competitive wage and employment is below the competitive level. A minimum wage set between the monopsony wage and the competitive wage can increase both wages and employment, because the employer faces a horizontal supply curve up to the minimum.
Fit to evidence. Aged care is publicly funded, with a small number of providers in many regions; migration settings have tightened, reducing labour supply. Providers report funding constraints. This is consistent with monopsony power, but not conclusive. If providers are price-takers in a national labour market, the competitive model is more relevant. The presence of a funding constraint can mimic monopsony: the provider cannot raise wages without losing money.
Verdict. Monopsony is plausible in thin regional markets; the competitive model is more relevant in urban markets. The policy should differentiate by region or sector rather than apply a single national wage floor.
2. Evaluate the claim that a higher minimum wage in aged care necessarily improves the welfare of low-paid care workers, taking account of public funding constraints and non-wage margins.

Direct effects. Workers who remain employed at higher wages gain; those who lose hours or jobs lose. In aged care, demand is inelastic, so job losses may be limited. But providers facing fixed funding may respond by reducing non-wage conditions: training, staffing ratios, or hours. If hours fall, weekly earnings may not rise.
Public funding constraint. Te Whatu Ora contracts are not indexed. A 2% wage increase adds $110m; if not funded, providers may cross-subsidise, reduce quality, or exit. Taxpayers may ultimately fund the increase if contracts are revised. The incidence is partly on taxpayers.
Non-wage margins. Quality of care may fall if providers cut staffing. Consumers (residents) may face higher fees if they are private payers. Workers may value the wage gain but lose in-kind benefits.
Distribution. Low-paid workers gain relative to other workers; if prices rise, real wages may be eroded. If taxpayers fund the increase, the cost is spread.
Verdict. The claim is not necessarily true: the welfare effect depends on hours, quality, and funding. A wage increase with indexed funding and quality safeguards is more likely to improve worker welfare than an unfunded mandate.
3. Assess the likely incidence of the wage increase across workers, firms, consumers, and taxpayers.
Read the worked answer
Workers. Gain if employed; lose if hours are cut. The net effect depends on labour demand elasticity and the hours response. In aged care, inelastic demand limits job losses; in hospitality, more elastic demand implies larger employment effects.
Firms. Hospitality margins of 3-5% mean a 2% wage increase for a large share of staff can compress margins. Firms may absorb the cost, pass it on, or reduce hours. In aged care, providers absorb the cost or reduce quality if funding is fixed.
Consumers. Price increases in hospitality; higher fees in aged care. Incidence depends on demand elasticity; in inelastic sectors such as aged care, pass-through is higher.
Taxpayers. If the government indexes contracts, taxpayers bear the cost; if not, providers and workers bear it. The fiscal cost is $110m in aged care alone.
Overall. The incidence is shared; the minimum wage is a blunt redistributive tool. A more targeted tool (in-work tax credits, sectoral wage subsidies) could achieve distributional goals with less distortion. But the minimum wage has low administrative cost and may have monopsony-correcting benefits. The appropriate policy mix depends on whether the goal is poverty reduction or wage compression.
