[2920] A map of Peninsula Malaysian districts based on the 2019 median household income

This is something that I have always wanted to see but I do not think I have seen them in the media. So, I decided to do it myself.

This is a map representing the median household median income for all Peninsular Malaysian districts, based on data from the 2019 Household Income Survey.

Out of 90 districts:

  • 3 districts have median of less than RM3,000 per month (all in Kelantan)
  • 29 districts between RM2,999 and RM4,000 per month
  • 24 districts between RM3,999 and RM5,000 per month
  • 16 districts between RM4,999 and RM6,000 per month
  • 9 districts between RM5,999 and RM7,000 per month
  • 3 districts between RM6,999 and RM8,000 per month (Klang, Johor Bahru, Kulai)
  • 6 districts RM8,000 per month and above (KL, Putrajaya, Gombak, Petaling, Sepang and Hulu Langat)

There are a lot of reds in the map but it is worth to remember, the map is not weighted by population. There are much more people living in the non-red districts than in the red ones.

On another point, Terengganu offers a contrast to the red-orange Peninsular east coast.

I used a Wikipedia map as the base and then colored it based on 7 income classifications I made. I have not done the same for Sabah and Sarawak because… the number of administrative districts there is humongous. And it took me about an hour to do this map alone.


[2168] Of no to the policy of One Price

Prices of the same tradable items in different places tend to converge in a perfectly efficient market. Theoretically, motivated by profits, individuals and entities act as arbitrageurs. They will continue to arbitrage until there are no more profits to be made. That is when prices equalized and that is the essence of the law of one price.

Prices may not actually converge to one price due to several factors however because market can be inefficient. Limited access to information crucial for the purpose of arbitrage may prevent convergence. Transportation cost as well as government intervention in terms of taxation and subsidization are two of several other important frictions. Instead of prices equalizing, a price spread exists to reflect those frictions even as market participants exhaust arbitrage opportunity.

This is essentially the reason why there is noticeable price differential for the same tradable goods sold in eastern and western part of Malaysia. With the South China Sea separating Malaysia into two parts, it is only natural for prices to differ between the two regions. Even under the price and supply control mechanism that exists in Malaysia, a kilogram of sugar for example, is sold 10 sen cheaper in Peninsular Malaysia than in Sabah and Sarawak. Transportation cost is a considerable barrier preventing actual convergence.

This is a source of discontent for some. Member of Parliament for Kalabakan, Abdul Ghapur Salleh of UMNO said in November 2009 said, “We’re talking about 1Malaysia, but we don’t even have one price” while alleging that the price differential is more insidious in nature — discrimination against Sabah and Sarawak — rather than simple economic friction.

It is unclear how exactly he wants effort at standardization to proceed but the approach by the federal government is clear. In the same month, Minister Koh Tsu Koon supported the idea of standardized prices across Malaysia and proposed that transportation cost be shared by all; in other words, introduce subsidy. Nearly a year earlier, Domestic Trade and Consumer Affairs Ministry wanted to do the same: subsidize transportation cost. In Sarawak itself, perhaps a harbinger preceding a possibly wider similar nationwide policy, the same ministry plans to subsidize transportation cost with the intention of standardizing prices of essential items sold in urban and rural areas under its “One Sarawak, One Price” campaign.

They are turning the law of one price on its head. Rather than letting market forces find its equilibrium where a particular price fits a particular landscape through a narrow band, the government intends to impose unnatural standardized prices for all situations everywhere to force convergence. The government intends to introduce more inefficiency to standardize prices.

The discontent over price differential is overrated. Two economists — Lee Chin and Muzafar Shah Habibullah of Universiti Putra Malaysia — published a paper in 2008 showing that prices of tradable goods between Peninsular Malaysia, Sabah and Sarawak are converging. Furthermore, the recent liberalization of cabotage policy — a protectionist policy that contributed to persistent price differential between eastern and western part of Malaysia — will likely further strengthen the natural convergence trend.

Convergence aside, to iterate the idea of how the difference is natural, the price differential has nothing to do with discrimination between the two parts of Malaysia. It is a reality that there is a large body of water separating the two parts of Malaysia. It is likely that if the transportation cost is brought down either through liberalization or improvement in technology, prices are likely to equalize, all else being equal.

The price differential due to transportation cost or distance has nothing to do with the idea of unity as much as it has something to do with the idea of discrimination. In the United States for instance, gas prices in Michigan and in California are very different. Even in the same state, prices of gas in one town can be different from another town a mile away. That does not make the person who pays higher price as less American than the other person who pays lower price for gas.

This idea can be expanded to Peninsular Malaysia. The government should not standardize prices within Malaysia. This is not to say just prices between Peninsular Malaysia, Sabah and Sarawak, but within those regions as well. What a free Malaysia needs is not a Price Control Act, but a Competition Act or antitrust law to fight collusion among businesses in order to encourage competition — the most effective method at encouraging convergence and low prices — without suffocating entrepreneurial spirit.

On top of that, maybe, just maybe, the move of having manufacturers based in Sabah or Sarawak is a cheaper and a more profitable option compared to the option of transporting goods from Peninsular Malaysia or from abroad even after accounting for various other effects like clusterization.

If the subsidization program goes through, it removes that incentive and hence, the possibility of developing industries in eastern Malaysia. If a business owner could transport his or her goods free from western to eastern Malaysia, why would the business owner locate his or her factory in eastern Malaysia? There are better ports, roads, financial services — practically everything that matters in business — in Peninsular Malaysia than in Sabah and Sarawak. The subsidization program would continue to industrialize the Peninsula while leaving Sabah and Sarawak farther behind in terms of development.

Besides, the Prime Minister recently said that private initiates and market forces have to be given freer rein while subsidies be phased out. The standardization of prices across Malaysia through subsidization of transportation cost by the government clearly contradicts that. Is this a proof that there is no coordination within the government? Or does words mean nothing to the government?

For the answer to be no on both accounts, the policy of “One Price” must be rejected.
