Reasons for Allocating Funds to Flood Protection and Skills Upgrading

Answer

The government allocates funds to flood protection and skills upgrading for distinct but related reasons rooted in its microeconomic objective of correcting market failure and its macroeconomic objective of growth. The thesis is that the two allocations rest on different failures — flood protection on the public-good problem, skills upgrading on imperfect information and positive externalities — and that both are justified, with the appropriate quantum of funds turning on the government’s information.

Flood protection — a public good. Flood protection (e.g. a flash-flood alert system) is a public good, being non-rival and non-excludable in consumption. It is non-rival because one resident receiving the alert does not diminish its availability to others — so the marginal cost of an additional user is zero. It is non-excludable because, once broadcast, non-payers cannot be prevented from receiving it. Non-excludability creates free-ridership: rational individuals conceal their demand, hoping others pay, so no demand is revealed in the market, no producer can profit, and the market produces nothing — complete market failure. Only the government, funding provision directly, can supply the good. The funds required depend on the seriousness of climate change and the cost of the necessary infrastructure, which may rise as climate volatility worsens.

Skills upgrading — imperfect information. The case for funding skills upgrading rests first on imperfect information. Workers undervalue the private benefit of upgrading because they cannot fully foresee it — better job prospects, advancement, higher pay — so their perceived marginal private benefit lies below the actual. They consume up to where $MPB_{perceived} = MPC$, short of the informed optimum where $MPB_{actual} = MPC$ — under-consumption and hence market failure. Topping up SkillsFuture credits both subsidises and signals the true benefit, raising take-up towards the optimum.

Skills upgrading — positive externality. Second, skills upgrading generates a positive externality: a more skilled worker benefits not only himself but third parties — firms enjoy higher productivity and lower average costs. With external benefits, marginal social benefit exceeds marginal private benefit, so the self-interested market consumes at $Q_e$ (where $MPB = MPC$) below the social optimum $Q_s$ (where $MSB = MSC$), under-consuming and generating a deadweight welfare loss.

Funding upgrading corrects this under-consumption by lowering its effective price towards the social optimum. The funds needed depend on the size of the information gap and the marginal external benefit at $Q_s$.

Macroeconomic reason — potential growth. Beyond correcting micro failures, investing in human capital raises labour productivity and, by improving workforce quality, attracts FDI. Both raise productive capacity — an outward shift of the PPC, or a rightward shift of LRAS — achieving potential growth, and, near full employment, easing the general price level. So the skills allocation serves a macroeconomic objective too.

Judgement. Both allocations are well justified, but on different grounds, which matters for assessing them. Flood protection is the stronger case in kind: as a pure public good the market fails completely, so government provision is not merely corrective but the only route to provision — there is no question of whether to intervene, only how much. Skills upgrading rests on the softer failures of imperfect information and positive externalities, where the market under-provides rather than fails outright; here the justification is genuine but the case is one of degree, and it gains decisive weight from the macroeconomic payoff to potential growth in an economy facing an ageing, disrupted workforce. The decisive consideration for both is the government’s information: the right quantum of funds depends on accurately estimating infrastructure needs (flood) and the information gap and external benefit (skills). Mis-estimation wastes resources or under-corrects. The defensible stand is that both allocations are appropriate, with flood protection justified unconditionally as a public good and skills upgrading justified by the combined weight of information failure, external benefits and long-run growth — both contingent on sound estimation of the optimal spend.
