3. Government policies to restrict the use of cars and encourage the public to use the Mass Rapid Transit (MRT) system continue to be a source of heated debate in Singapore.
Assess the effectiveness of the policies available to the Singapore government in overcoming market failure in Singapore’s land transport market. [25]
Explain market failure in Singapore’s land transport market
In the consumption of roads via motor vehicles, individuals only take into consideration their own MPC & MPB
cost of driving like petrol, car and the
convenience derived from driving
However, they contribute to congestion which generates negative externalities
Extra travelling time, less leisure, less work
Increased business costs
Increased pollution
Higher probability of accidents
These are not taken into consideration, causing divergence between MPC & MSC
Since consumption occurs at the market equilibrium Qm instead of the socially optimal level Qs, and Qm > Qs, there is overconsumption resulting in deadweight loss and therefore market failure occurs
Taxes
Electronic Road Pricing
a form of congestion pricing to force individuals to internalize the external costs associated with driving on congested roads during peak hours – will directly get motorists to avoid such roads and help alleviate congestion on these roads
Registration Fee, Additional Registration Fee, Road Tax –
$220 – Registration Fee
100% to 180% of Open-Market Value – Additional Registration Fee
Varies based on engine capacity – Road tax
These various taxes adds towards the cost of car ownership and discourage the use of cars in Singapore (in general)
Effectiveness of taxes
ERP may not be significant enough to reduce congestion significantly as vehicle owners may see it as a small % of the total cost of car ownership
Broad-based taxes does not directly reduce congestion
Quotas
Vehicle Quota System
Vehicle population growth rate is currently allowed at 0% (reducing from 3% prior to 2009). Those who wish to buy a car will have to bid for COEs based on these quota. Prices of COE will be determined by demand & supply. The Vehicle Quota System directly limits the population of cars in Singapore. So long as the growth of roads exceed the growth of car population in Singapore (currently 0%), the problem of congestion should ease.
Effectiveness of quotas
Problem of buffet syndrome – where users seek to maximise car usage to account for the high costs of ownership that they have already paid for
Does not directly address the problem of road usage causing congestion
Encouraging the use of public transport
Improving the accessibility, convenience and comfort of public transport
as part of the Transport Masterplan, the goal is to have a train station within 5 minutes’ walk of each residential home in Singapore. By making public transport a better substitute to private transport, it will reduce the use of cars on roads, helping to address the problem of congestion
Effectiveness
Worsens congestion in the immediate term with the vast number of public works project causing significant road diversions
Takes a long time and costly
