Innova Junior College Prelim 2 2011 H2 Question 3 Wireless@SG is a wireless broadband programme developed by Info-communications Development Authority of Singapore. Registered Wireless@SG users are able to enjoy free wireless broadband access with speeds of up to 1 Mbps at public areas within its coverage. Wireless@SG is powered by the network of three wireless operators: iCell, M1 and SingTel. a) Explain the key differences between “public good” and “merit good”, and consider whether Wireless@SG is an example of a public good. [12] Introduction: Definitions Public goods Merit goods Body: Key differences between public and merit goods Consider whether Wireless@SG is an example of a public good Degree of rivalry - Non-rival vs rival in consumption  Public goods are non-rival in consumption i.e. consumption of the good by one user does not diminish the amount of the good available to additional users. As such Marginal Cost of providing the good to the additional user is zero. Examples include the provision of national defence – the provision of national security protection for one citizen does not diminish the level of security provided to additional citizens  Merit goods may be rival in consumption i.e. when one user consumes, it will diminish the amount available to additional users. In this light, Wireless@SG, on the surface, seems to be a public good. Access to the network by one user does not mean that an additional user will be excluded in the consumption i.e. it can support multiple users. However, closer examination of the market  A s m o r e a n d more additional users access the network, this will slow down the speed of access  additional user can lead to rivalry in consumption in terms of speed of access. Degree of excludability - Non-excludable vs excludable to non- paying users  Public goods are non-excludable to a non-paying user i.e. it is not possible to prevent a non-paying user from enjoying the benefits of consumption of a good. This can potentially lead to a free rider problem since there is no incentive for consumers to pay. E.g. once a pedestrian sheltered walkway is built, it is not possible to prevent non-payers from using the walkway.  Merit goods may be non-excludable to non-payers. In this light, Wireless@SG seems more likely to be a merit good rather than a public good. Only registered users can enjoy the free access. Similarly if charges need to be imposed, non- payers can be easily excluded via non-registration.

Extent of market failure and government intervention – complete vs partial  Public goods, due to non-rivalry and non-excludability as mentioned above, gives rise to the free-rider problem. No direct charge can be levied on the user. Therefore, left to the free market, there is zero provision  complete market failure. Hence there is often a need for government provision.  Merit goods, on the other hand, can be provided pro
