Is Information Failure the Main Cause of Government Intervention in Singapore?
Question
Information failure is a growing concern in Singapore, amidst a rise in anti-vaccination sentiments. The Singaporean government has employed various measures to combat this, including extensive education campaigns.
(b) Assess the extent to which information failure, rather than other sources of market failure, is the main cause of government intervention in Singapore. [15]
Answer
Thesis. A government intervenes in the free market to correct market failure and restore allocative efficiency. Information failure is one source of failure in Singapore, but it competes with others — most notably the non-provision of public goods. Comparing the two by severity and urgency, I argue that public goods, not information failure, is the principal cause of government intervention in Singapore, though both demand a response.
Information failure warrants intervention. Through ignorance and misinformation — the anti-vaccination sentiment cited in the preamble — Singaporean consumers suffer imperfect information in the market for vaccinations, falsely believing that vaccination will harm them and so under-estimating its true private benefit. This drives a divergence between the perceived and the actual marginal private benefit. Consumers transact at where ; assuming no externalities, the socially optimal quantity is where . The shortfall is an under-consumption of vaccinations: over that range the forgone private benefit exceeds the forgone private cost, leaving a deadweight welfare loss that warrants government intervention through education and moral suasion. (This failure is examined in prose; the 9570 syllabus carries no imperfect-information diagram.)
Evaluation. The severity of this failure in Singapore is, however, likely modest. Compulsory formal schooling of at least six years sharply reduces consumers’ susceptibility to misinformation, so imperfect information bites less here than in less-developed economies. The deadweight loss from information failure is therefore probably contained.
Public goods warrant intervention — more severely. A public good is non-excludable and non-rivalrous in consumption, and the free market fails to provide it at all — a complete market failure. National defence is the canonical Singaporean case: once provided, consumers can free-ride and enjoy security without paying; with no one willing to pay there are no price signals, so no profit-maximising producer will supply it. The government must therefore provide public goods directly to secure the socially optimal quantity.
Evaluation. The severity of any market failure depends partly on the number of consumers affected. Singapore’s relatively small population might suggest the welfare loss from non-provision of a public good is smaller than in a more populous economy — a consideration that tempers, though does not overturn, the case below.
Weighing the two. On severity, Singapore is a small island state surrounded by far larger regional military powers, so the socially optimal level of national defence is very high; without provision, the allocative inefficiency would be extensive — more severe than that from information failure. On urgency and reach, because public goods are a complete failure, non-provision would affect every consumer in the short run, with a correspondingly large welfare cost; information failure, by contrast, distorts a single market and affects a smaller group, so its short-run welfare cost is lower. On both counts public goods dominate.
Conclusion. Information failure is a genuine but secondary cause of government intervention in Singapore: public goods, as a complete market failure of nationwide reach and high severity, is the main cause. The judgement turns on severity and urgency rather than on the bare existence of a failure. That said, the conclusion is comparative, not exclusive — both information failure and public goods must be addressed if Singapore is to maximise welfare and achieve allocative efficiency.
