GCE ‘A’ Levels Nov 2008

(a) Explain why imperfect information and immobility of factors of production may lead to market failure. (10)

b) Evaluate the policies currently used by the Singapore govt to correct these causes of market failure. (15)

(a) Explain why imperfect information and immobility of factors of production may lead to market failure. (10)

Intro• Define mkt failure

–Mkt failure arises when the free market fails to achieve an efficient allocation of resources and when social goals are not met.

imperfect info market failure

Imperfect info

Individuals do not fully know private benefits/costs of consuming certain goods

Individuals are not aware of external benefits/costs of consuming certain goods

Personal Well-being Externalities

Demerit goods (eg cigarettes)• Define demerit goods: gds that govt perceivesas bad for the individual consuming them

• Individuals may not be fully aware of the ill‐effects on their health underestimate their private costs when consuming cigarettes (OR overestimate private benefit) Incorrect valuation of private benefit (MPB/DD)

Occupational immobility

Geographical immobility

Occupational immobility• Eg: workers retrenched from electronics industry unable to gain re‐employment in growing industries 

• Mismatch between skills offered by the workers and skills required by new industries

Geographical immobility• Eg: Labour may face difficulty in moving from one place to another to find work(eg family ties, difference in cost of living)

• Unable to channel labour resources to areas where there are shortages of labour unemployment

• Note: This may not be applicable to Singapore. More applicable for large countries with huge regional disparity

In conclusion…

• Mkt failure: Inefficient allocation of resources: can be manifested as–under/over allocation of scarce resources to certain goods

–resources not being fully utilized(wastage of scarce resources)

3b) Evaluate the policies currentlyused by the Singapore Governmentto correct these causes of marketfailure. [15]

Imperfect Info

Factor Immobility

• In view of the over‐consumption of cigarettes caused by imperfect information among private individuals, the Singapore govt has implemented policies such as:

Education & Campaigns• Anti‐smoking campaigns carried out by Health Promotion Board (HPB) eg. Anti‐smoking advertisements through various forms of media, anti‐smoking road‐shows, anti‐smoking telephone help‐lines

imperfect info market failureDemerit goods (eg. cigarettes)

Legislation• Health warnings on the damaging effects ofsmoking are to be conspicuously indicatedon cigarette packs.Eg.– ‘SMOKING CAUSES HEART DISEASE’– ‘SMOKING HARMS YOUR FAMILY’– Gory images

• Misleading labeling on tobacco productssuch as “light”, “mild” and “ultra‐light” is notpermitted.

Legislation–Cigarette companies are banned from sponsoring public events and arts programs 

–Govt sets a minimum legal age (18) to purchase and smoke cigarettes 

–Revoke licenses of retailers who sell tobacco products to buyers in school uniform (with 1st offence)

Explain how measures work?• Actions undertaken attempt to solve the root cause of over‐consumption of cigarettes on the part of private individuals i.e. Imperfect info DD for cigarettes corrects the market failure problem

Explain how policy works?

EvaluationHowever, these policies may also have their limitations:Govt has to incur additional monitoring and enforcement costs to ensure compliance to legislation education & campaigns are costly to 

implement effects of education & campaigns are uncertain and can only materialize in the longer term

imperfect info market failure Merit good (preventive healthcare such as breast cancer screening, vaccination)

• In view of the under-consumption of healthcare services caused by imperfect information, the Singapore govt has implemented policies such as:

• Education & Campaigns:E.g. Promotion of pre-emptive measures such asbreast cancer screening etc through variousforms of media, cancer screening road-shows,mobile screening vans

Evaluation:• Actions undertaken attempt to solve the root cause of under‐consumption of healthcare svcs on the part of private individuals ie. Imperfect info; thereby raising the Dd for healthcare svcs, thus solving the market failure problem.

SOLUTION??

Imperfect infomarket fails

LegislationMedical practitioners are strongly encouraged to display prices of their services clearly so that patients are given full knowledge of costs of their medical treatment.

Evaluation (limitations)• Positive effects of retraining programs will only materialize in the long term.

• Besides, effectiveness of the skills programs also depends on the –motivational levels of the workers involved– the willingness of firms to employ older workers

– firms’ willingness to conduct training programs

Geographical immobility• Geographical immobility is not really valid in Singapore’s context. 

• In any case, Singapore government has invested in improving the transportation facilities, in terms of efficiency as well as accessibility 

Factor immobility Mkt fails

Presence of strong BTE• Monopoly power that is created as a result of firms gaining control over key FOPs is not a significant problem in Singapore due to the existence of the Competition Commission of Singapore (CCS) and the implementation of the Competition Law.

Factor immobility Mkt fails

Conclusion• As each policy has its pros & cons, govt needs to carry out its CBA before deciding on set of policies to implement.

Conclusion• Perhaps better to adopt a multi‐pronged approach by using a combination of policies –eg. Use of taxation together with legislation & education/campaigns for demerit gds

• Govt also needs to be aware of govt failure!
