Wednesday, May 20, 2009 Kopi, teh still at same price
By Leow Si Wan
COFFEESHOP patrons grumbling about the rising cost of living may be pleased to know that prices of the hot cup of coffee they are sipping have largely stayed the same since February.

The average price of kopi and teh - local coffee or tea with condensed milk - has held steady at 80 cents for the past three months, while a canned drink of green tea, Coke or Pepsi costs about $1.20.

These figures come from the Consumers Association of Singapore's (Case) second beverage price survey released on Tuesday.

The consumer watchdog surveyed 151 drink stalls islandwide between end March and early April.

The first survey in February only measured the price of a cup of kopi, teh, and a can of Pepsi or Coke.

Case found that since then, fewer than 10 per cent or eight drink vendors had raised kopi and teh prices by 10 cents. Four other stalls lowered prices by the same amount.

For Pepsi and Coke, nine stalls upped prices by 10 cents, while three others lowered prices by 10 to 20 cents.

In its second survey, Case checked the prices of a wider range of drinks including regular cans of chrysanthemum tea, soya bean drink and H20.

Besides prices, Case also looked at whether vendors displayed prices of their beverages clearly.

It found that over half of the vendors did not display prices upfront - 72 did not put up beverage prices prominently and 18 displayed only the prices of kopi and teh.

Among those who showed prices, two charged about 10 to 20 cents more than what was stated.

From: Mr Ho

I've thought about some of the questions the classwas asking regarding market failure just now, and these are some of myanswers

Claire's question about externalities being"subjective". She gave the example of a person who "didn't mind" beingaffected by secondhand smoke. So if the person "doesn't mind" is therestill an externality? My answer is that externalities still existbecause there is still an external cost being imposed upon the person.In the long run, he or she will still have to end up spending money onmedical bills due to the second hand smoke, so externalities are notsubjective. Please go by the definition of either an external cost orbenefit being imposed on a third party when identifying externalities.

ForCamilus's question about how the "private cost" of the suicide of aperson owing money leading to an "external benefit" to his family asthey will not have to be harrassed by the loanshark, this is totallyirrelevant to the concept of private cost and external benefit!

Theconcept of private cost and external benefit apply when it involves theproduction and consumption of goods and services, but in this case,there are absolutely no goods and services invoved. So how can you talkabout private cost and external benefit?

The last question aboutthe case study scenario I gave whereby the lady suffering asthma wasgiven first aid and hence "compensated" for the negative externality imposed on her is a valid point. I agree that in this case, there is no externality since the third party has been compensated. I should have made the externalities in the scenario clearer. But the fact that the class brought up this point is very good and shows you all are thinking through the concepts taught. Keep it up!

Wednesday, April 08, 2009 economics of market failure
There is a clear economic case for government intervention in markets where some form of market failure is taking place. Government can justify this by saying that intervention is in the public interest. Basically market failure occurs when markets do not bring about economic efficiency.

Government intervention occurs when markets are not working optimally i.e. there is a Pareto sub-optimal allocation of resources in a market/industry. In simple terms, the market may not always allocate scarce resources efficiently in a way that achieves the highest total social welfare.


There are plenty of reasons why the normal operation of market forces may not lead to economic efficiency.

Public Goods

Public Goods not provided by the free market because of their two main characteristics

  • Non-excludability where it is not possible to provide a good or service to one person without it thereby being available for others to enjoy
  • Non-rivalry where the consumption of a good or service by one person will not prevent others from enjoying it

Examples: Street lighting / Lighthouse Protection, Police services, Air defence systems, Roads / motorways, Terrestrial television, Flood defence systems, Public parks & beaches

Because of their nature the private sector is unlikely to be willing and able to provide public goods. The government therefore provides them for collective consumption and finances them through general taxation.

Merit Goods

Merit Goods are those goods and services that the government feels that people left to themselves will under-consume and which therefore ought to be subsidised or provided free at the point of use.

Both the public and private sector of the economy can provide merit goods & services. Consumption of merit goods is thought to generate positive externality effects where the social benefit from consumption exceeds the private benefit.

Examples: Health services, Education, Work Training, Public Libraries, Citizen's Advice, Inoculations


Few modern markets meet the stringent conditions required for a perfectly competitive market. The existence of monopoly power is often thought to create the potential for market failure and a need for intervention to correct for some of the welfare consequences of monopoly power.

The classical economic case against monopoly is that

  • Price is higher and output is lower under monopoly than in a competitive market
  • This causes a net economic welfare loss of both consumer and producer surplus
  • Price > marginal cost - leading to allocative inefficiency and a pareto sub-optimal equilibrium.
  • Rent seeking behaviour by the monopolist might add to the standard costs of monopoly. This includes high (possibly excessive) amounts of spending on persuasive advertising and marketing.
  • Libenstein's X-inefficiency may also result if the monopolist allows cost efficiency to drop. An upward drift in costs because of a lack of effective competition in the market-place can lead to consumers facing higher prices and a reduction in their real standard of living


Any exam question on market failure must make some reference to externalities. What are the potential market failures arising from externalities?

The social optimum output or level of consumption diverges from the private optimum.

Main problem is the absence of clearly defined property rights for those agents operating in the market. When property rights are not clearly defined, market failure is likely because producers & consumers may not be held to account

Don't forget that positive externalities can also justify intervention if goods are under-consumed (social benefit > private benefit)


Market failure can also be caused by the existence of inequality throughout the economy. Wide differences in income and wealth between different groups within our economy leads to a wide gap in living standards between affluent households and those experiencing poverty. Society may come to the view that too much inequality is unacceptable or undesirable.

Note here that value judgements come into play whenever we discuss the distribution of income and wealth in society. The government may decide to intervene to reduce inequality through changes to the tax and benefits system and also specific policies such as the national minimum wage


Government intervention may seek to correct for the distortions created by market failure and to improve the efficiency in the way that markets operate

  • Pollution taxes to correct for externalities
  • Taxation of monopoly profits (the Windfall Tax)
  • Regulation of oligopolies/cartel behaviour
  • Direct provision of public goods (defence)
  • Policies to introduce competition into markets (de-regulation)
  • Price controls for the recently privatised utilities

abt market failure
Market Failure

A market failure occurs when a market fails to allocate resources efficiently. A market allocates its resources in the following ways:

Social Efficiency: where external costs and benefits are accounted for
Allocative Efficiency: where society produces goods and services at minimum cost that are wanted by consumers.
Technical Efficiency is the production of goods and services using the minimum amount of resources.
Productive efficiency: Production of goods and services at the lowest factor cost.

Market Failure occurs when
-knowledge is not perfect,
-goods are differentiated,
-resource immobility,
-Market power,
-services and goods are provided in sufficient quantity by the market
-existence of external costs and benefits
-inequality exists.

Inadequate Knowledge

-Consumers do not have adequate technical knowledge
-advertising can mislead/misinform
-consumers unaware of all opportunities
-producers cannot accurately measure productivity
-decisions based on past experiences rather than future knowledge

Goods/Services that are differentiated

-Designer Labels
-Technology-lack of understanding of impact
-labeling and product information

Resource Immobility

-Factors that are not fully mobile
-Labour immobility-geographical and occupational
-Capital immobility-
-Land (transport) - cannot be moved to where it is needed

Market Power

-Existence of monopolies and oligopolies
-Price Fixing
-Abnormal profits
-Rigging of markets
-Barriers to entry

Inadequate provision

Merit goods and public goods
-Could be provided by the market but consumers may not be able to afford or feel the need to purchase-market would not provide them in the quantities society needs.
E.g. sports facilities/ universities.

Public goods
-Goods and services that markets would not be able to provide at all.
E.g. headlamps on highways/street signs.

Person paying for benefit cannot prevent anyone from also benefiting.

Large external benefits in relation to the cost -socially desirable but not profitable to supply.

De-merit goods
-Goods which society over-produces
-Goods and services provided by the market which are not in our best interests.
E.g. Alcohol

External costs and benefits
Cost of economic decision to a third party
Benefits to a third party as a result of a decision made by another party. E.g. education, public transport etc.
Decision-makers do not take into account the cost imposed on society and others as a result of their decision.
E.g. pollution

Market Failure:
-Poverty-absolute and relative
-Distribution of factor ownership
-Distribution of income
-Wealth distribution

Measures to correct market failure:
-State provision
-Extension of property rights
-Positive discrimination
-Redistribution of income

Well, because I am the first to start on the topic of market failure, I shall define what is a market failure first.

"In economics, a market failure exists when the production or use of goods and services by the market is not efficient. That is, there exists another outcome where all involved can be made better off. Market failures can be viewed as scenarios where individuals' pursuit of pure self-interest leads to results that are not efficient – that can be improved upon from the societal point-of-view.The first known use of the term by economists was in 1958, but the concept has been traced back to the Victorian philosopher Henry Sidgwick.

Market failures are often associated with non-competitive markets, externalities or public goods. The existence of a market failure is often used as a justification for government intervention in a particular market. Economists, especially microeconomists, are often concerned with the causes of market failure, and possible means to correct such a failure when it occurs. Such analysis plays an important role in many types of public policy decisions and studies. However, some types of government policy interventions, such as taxes, subsidies, bailouts, wage and price controls, and regulations, including attempts to correct market failure, may also lead to an inefficient allocation of resources, (sometimes called government failures). Thus, there is often a choice between imperfect outcomes, i.e. imperfect market outcomes with or without government interventions."

Saturday, March 14, 2009 SPH cuts wages 10 min
March 13, 2009
Decision will slash wage bill by 20%; higher-paid staff to bear the brunt of the cuts
By Alvin Foo

MEDIA group Singapore Press Holdings (SPH) announced salary cuts for about 3,000 staff yesterday, among other cost-saving measures to cope with the economic slowdown.

Staff were told of the measures, which also include a hiring freeze, at a briefing in the afternoon after the share market had closed.

FACING THE DOWNTURN'It is imperative that we prepare for a longer-than-expected downturn so that we can emerge stronger when the economy recovers.'

The pay cuts will range from 2 per cent to 10 per cent and take effect on April 1. The company will grant extra leave to staff whose pay will be trimmed.

Singapore's largest listed media company said the cuts, together with reductions in profit-related bonuses, will slash the wage bill for its key businesses by an estimated 20 per cent.

SPH chief executive officer Alan Chan said: 'We need to bring our costs down in the face of a weaker advertising market and an uncertain business environment.

'It is imperative that we prepare for a longer- than-expected downturn so that we can emerge stronger when the economy recovers.'

SPH has also instituted steps such as slashing operating expenses and a recruitment freeze.

Higher-paid staff will bear the brunt of the wage cuts. Those earning $2,000 and below a month will not be affected.

The company said the wage revision was done following negotiations with its two unions.

Mr Johari Sadli, general secretary of the 1,000-member SPH Employees' Union, said: 'It is a measure to prevent more drastic action later on. It is never easy when it comes to wage cuts, but our members generally understand the economic situation.'

Billionaire ranks shrink by 30%

Their net worth is down by US$2 trillion; only two Singaporeans on list
NEW YORK: The meltdown of global financial markets slashed the ranks of the world's billionaires by 30 per cent in 2008, Forbes magazine reported yesterday in its annual tally of the planet's richest people.
Russians and Indians were the hardest hit this year, losing ground to the United States, which reasserted its dominance over the world's wealthy elite.


Overall, the net worth on the list of 793 billionaires - down from 1,125 billionaires in 2008 - plummeted to US$2.4 trillion (S$3.7 trillion), from US$4.4 trillion the year before.

Only two Singaporeans were listed - down from five the year before - Far East Organisation's Ng Teng Fong and United Overseas Bank's Wee Cho Yaw.

'The world has become a wealth wasteland,' Forbes declared in its report. 'Like the rest of us, the richest people in the world have endured a financial disaster over the past year.'

Overall, the US continued to dominate the list with the most billionaires - 359. Europe had 196, Asia-Pacific 130, the Middle East and Africa 58, and the Americas outside the US 50.

Microsoft founder Bill Gates' net worth dived to US$40 billion from US$58 billion, but he reclaimed the title of world's richest man after two other billionaires - Berkshire Hathaway CEO Warren Buffett and Mexican business magnate Carlos Slim Helu - lost more on paper than he did.

Collectively, these three men lost US$68 billion in the year to Feb 13, when Forbes took a snapshot of wealth around the world to compile its annual list of billionaires.

It was the first time since 2003 that the number of people on the list decreased, and the biggest drop since the magazine began the ranking 23 years ago.

Billionaires in developing countries - including those in Asia - were especially hard hit by the global crisis.

India lost more than half of its billionaires, with the biggest gainer becoming the biggest loser. Indian businessman Anil Ambani was ranked sixth last year but fell to 34 after he had US$32 billion wiped out over the last 12 months.

'India took a huge whack,' noted Ms Luisa Kroll, senior editor of Forbes.

Singapore had three of its five billionaires fall off the list: Mr Zhong Sheng Jian, chairman of property group Yanlord Land, Wilmar International chief executive Kuok Khoon Hong, and King of the Remisiers Peter Lim.

Mr Lim, however, shrugged it off. 'Aiyah, what's the problem,' he told The Straits Times. 'Dropped out, not dropped dead.'

Other notable people who suffered the same fate included Facebook CEO Mark Zuckerberg, former Citigroup chairman Sanford 'Sandy' Weill and former American International Group CEO Maurice 'Hank' Greenberg.

There were, however, 44 people in Forbes' list who saw their wealth rise. They included New York City Mayor Michael Bloomberg, investors George Soros and Ronald Perelman - and entertainer Oprah Winfrey.

Crime, however, did not disqualify one notable new entry to the list - Mexican drug lord Joaquin 'Shorty' Guzman, who is among the world's most wanted men and now worth US$1 billion.

Chief executive of Forbes Magazines Steve Forbes said that while few would shed a tear for the plight of a billionaire, it was bad for the economy when entrepreneurs were in trouble.

'Billionaires don't have to worry about their next meal, but if their wealth is declining and you're not creating numerous new billionaires, it means the rest of the world is not doing very well,' he said.
