[1633] Of rice is up but not vegetable

A sudden realization of a global food crisis among the public, or rather, prices increase of rice, has prompted several questions relating to supply chain and economics. One interesting economic question that I was requested to answer was why prices of fresh produce are not treading the path of rice prices?

To be honest, I have not seen the relevant data for fresh product — which by the way generally means vegetable — but the increase in rice prices is painted all over the news. But if we take the implicit assumptions of the question as true, why indeed do we not see the same pattern that dominates the rice market in the fresh produce market?

When I read the question, price effect, elasticity of demand and the Engel’s Law came to mind.

The Engel’s Law is an economic observation first expressed by statistician Ernst Engel[1] in the 19th century which states that a proportion of income dedicated to food, mostly starches, is larger the poorer a person is. I believe the Engel’s Law does answer the question to some extent.

Allow me to explain. Take a deep breath too.

An individual has some amount of income and a fraction of that income is dedicated to food. That fraction is further distribution among various kinds of food and we shall make a simple model which consists of staple food and luxury foodstuffs. We assume expenditure on other items as constant. Or, to make it easier, let us assume that we live to eat.

When price of staple food goes up, the person will have less purchasing power; that means he could buy less staple food for the same amount of money compared to before the price increase. If he wants to consume the same amount of luxury foodstuff, he will have to cut his consumption of staple food. The issue here is that it is staple food and staple food translates into low elasticity of demand. In simple English, changes in price do not affect quantity demanded by too much.

Therefore, cutting back on staple food consumption may not be the most preferred option. Thus, he cuts back on luxury foodstuffs while trying to maintain his current rice consumption level. As a result, demand for rice stays put, or falls only slightly while demand for other foodstuff falls dramatically.

This predicts a fall in prices for fresh produce demand while rice prices would stay constant, if everything else is the same.

With the background of increasing population size across the world, demand in general may be on the rise, causing a general upward pressure on prices of all goods. It has to be noted that a majority of those in a society is mostly made up of lower and middle class individuals and this is the relevance of Engel’s Law. What this explanation may lead to is this: while prices for both goods may increase, rice prices grow faster than luxury foodstuffs by virtue of constant demand for rice of an individual and decreased demand for luxury foodstuff of an individual with increasing population size.

Finally, a possible anomaly happening at the demand curve: the curve is most likely to be a vertical line perpendicular to the quantity axis or something close to that. I wish I had Matlab or something with me. I would love to run a model with the associated indifference curves.

[1632] Of freer trade for rice, please

Tyler Cowen writes:

At first glance, this seems understandable, because a country may not wish to send valuable foodstuffs abroad in a time of need. Nonetheless, the longer-run incentives are counterproductive.

Export restrictions send a message to farmers that their crops are least profitable precisely when they are most needed. There is little incentive to plant, harvest or store enough rice — or any other crop, for that matter — as a hedge against bad times. [Freer Trade Could Fill the World’s Rice Bowl. Tyler Cowen. New York Times. April 27 2008]

Also from Indonesia:

We know that:
a. The world rice prices hit the $1,000-a-tonne level for the first time
b. Indonesia’s rice production is estimated to be about 2m tonnes higher than consumption this year thanks to improving yields and an increase in the harvested area.

What can you infer?

Yes, sell the surplus and reap the windfall profit. I heard you said you always want to help rice farmers. [High Price Rice Quiz. café salemba. April 23 2008]

Despite having a surplus, Indonesia is restricting rice export with hope to slow down the march of local rice prices to achieve parity with prices in the international market.[1]

And, ehem, hey you protectionist Malaysians, how do you feel to be on the other end of protectionist policy now?

[1631] Of a silver lining behind the food crisis

Fair use.The Doha Round is a trade negotiation on a global scale which seeks to lower trade barriers with the ultimate goal of promoting free trade among members of the World Trade Organization. The birth of the Round was difficult and development surrounding the Round is riddled with seemingly insurmountable challenges. In Cancun, Mexico for instance, a trade talk famously collapsed only after 4 days of negotiation.[1] There are several major hurdles all WTO members have to overcome but with the current buzzword being the “food crisis”,[2] farm subsidies enjoyed by farmers in the US and EU are of special interest and it has been associated with developmental issues in Africa.

The agricultural subsidy distorts the market by bringing the cost of production artificially down, artificially increases supply from the developed world and artificially drives prices down.[3] Some quantity of the artificially low-priced food is then exported to impoverished countries where it will compete with locally grown food which is more expensive than imported food.[4] Along with cheap food being flooded in the local market by aid groups which further depresses local food prices,[5] it simply does not make sense for farmers in the countries to be involved in food production. African farmers are unable to utilize their possible comparative advantage under free market while farmers in the developed world are investing in sectors which they do not have comparative advantage. Thus, African countries have little incentive to build their capacity in sectors which they are best positioned to take thrive under free market.

A solution to this problem is the removal of farm subsidies in the developed world. The removal will see the agriculture industry in the developed world to decline in importance. The vacuum will then be taken over by farmers in poorer countries with comparative advantage in agriculture. These poor countries could build up its food production capacity while creating the much needed employment opportunities for the local. Through this, poor African countries have a chance of pulling themselves up rather than relying on aids that bring limited opportunity for economic growth.

The issue with this solution is that while on a very big picture narrative, it allows greater efficiency in resources utilization, the move will increase food prices paid by Africans, possibly beyond the means of the poor despite giving local producers the signal they need to seriously invest in food production industry. With the agricultural subsidy in the developed world gone, prices will immediately go up to free market prices of food produced in the developed world. Quantity of food produced will also drop until replacement farms are up and running. And even if changes occur immediately — where the agriculture industry in the developed world would die off immediately and instantaneously replaced by new farms in Africa — cost of food produced could possibly still be higher than the ones subsidized though it would still be cheaper than food originating from unsubsidized farms in the developed world, with everything else constant.

Yet, the pain suffered is only short term in nature; capability building will slowly bare fruits that will fuel the economy, setting the stage for a brighter future.

Price is an important signal in decision-making processes. Higher crude oil prices have encouraged energy companies to conduct explorations for the black gold in remote places all over the world. Similar to the trend seen in the oil and gas sector, higher biofuel prices have encouraged expansion of palm oil plantation in Indonesia and sugar cane in Brazil. The same trend is applicable to the food sector.

Food prices have been steadily increasing for the past couple of years due to several factors. The increase has proven to be sufficiently high that the IMF has cautioned the world community that we are facing a food crisis. Riots related to food availability have occurred at a number of places across the world. It is clear that food supply needs to increase or else, Malthus would have a day in the sun.

It is unclear how much food would be produced however if the relevant farms migrated from the developed world to African countries as well as to countries with agriculture as their comparative advantage. Four factors are crucial in answering that question on quantity: labor, land, capital and technology. A free market world is the one with free flow of capital and labor but that is an idealistic world. Our world, for now, is characterized with capital flowing more freely than labor though labor, especially in the more globalized part of the world, is increasingly becoming more mobile. The developed world has plenty of capital and high technology related to farming but they lack the labor and in many places, land. The third world such as African countries has plenty of labor and land but most definitely lacking the capital and the know-how. Given difference in endowment, which should go where?

I am in the opinion that the more mobile factors should move and that means relocation of farms from the developed world to the third world. Labor and land do not go around easily but the contrary is true for capital and technology. With all four factors concentrating at a focus point, it is possible for food production to increase on the net with full utilization of comparative advantage.

As a recap, higher priced food should attract more players into the agriculture industry, including in Africa. If there is enough pressure on market prices to increase higher than production cost, poor farmers suffering from developed countries’ agricultural subsidy policy should be able to begin to build their capacity in food production. Now, these local farmers could compete with foreign subsidized competitors.

If that is so, perhaps the removal of food subsidy might not be so central in the issue of African development anymore. This however does not justify agricultural subsidy policy in the developed countries. What this means instead is that the farmers in Africa may bow have an avenue to pull themselves out of poverty in spite of market distorting subsidy enjoyed by farmers in the developed world. A respect for comparative advantage and the market meanwhile should increase food production until a point where all four factors meet the ultimate point of diminishing returns to scale.

[5] — The delivery of food aid to developing countries seems like an uncontroversial policy — a straightforward effort that helps the poor and underscores the generosity of donor nations. Yet, economists have long debated the merits of food aid. By increasing the local supply of food, such aid may depress prices and thus undercut the income of rural farmers in the recipient nations, for example; it also may discourage local production. And, since the poor often are concentrated in rural areas, food aid in fact may disproportionately hurt the poor. [Does International Food Aid Harm the Poor?. Carlos Lozada.

[1630] Of libertarian wet dream is now a government policy

Never I actually thought this would ever be implemented: cash transfer instead of in kind!

PUTRAJAYA: The government is looking at ways to channel cash to the neediest target groups should the diesel subsidy be removed.

Deputy Prime Minister Datuk Seri Najib Razak, commenting on a Domestic Trade and Consumer Affairs Ministry announcement on Thursday that the price of diesel at petrol stations would soon be set at market rates, said the government was finalising methods of issuing cash to the groups most in need of the subsidy. [Cash instead of diesel subsidy for needy groups. New Straits Times. April 26 2008]

Cash transfer is superior to subsidy simply because of one economic concept: indifference curve.

Admittedly though, this policy suffers from moral hazard problem: the cash will be used for things other than diesel. But hey, only an individual knows his indifference curve. Let him decide if he really needs the diesel. Cash improves an individual’s indifference curve more effectively than in kind subsidy.

The government’s job here, if this program is to work, is to identify those who really need the cash transfer. That would be a tough job: it is another problem known in economics as adverse selection.

p/s — okay, I am overreacting. This is not quite a wet dream that I claimed it to be as libertarians are not too fond of wealth redistribution policy but I was overjoyed when I read the news nonetheless. It is still a superior policy to the previous version. Any microeconomics textbook will tell you that.

I am quite happy to see movement against subsidy is growing healthily despite the result of the general election on March 8. While PKR had successfully played the populist sentiment by supporting greater fuel subsidy and PAS offering fattening welfare state alternative, it seems that all that has not been successful in stopping the implementation of more liberal economic policies.

The economy should be in the upswing soon as more rational economic policies are set in place. Even without that, I am already optimistic about the future. The worst seems to have past, minus the discount created by slight political uncertainty in Malaysia.

[1629] Of is biofuel the cause of the food crisis?

Roger Cohen at the NYT insists that biofuel is not the cause of food crisis, or at least not a major one if one wants to be accurate about magnitude, since it is still a small industry. Instead, he is convinced that what is causing it is protectionism.

Much larger trends are at work. They dwarf the still tiny biofuel industry (roughly a $40 billion annual business, or the equivalent of Exxon Mobil’s $40.6 billion profits in 2007). I refer to the rise of more than one-third of humanity in China and India, the disintegrating dollar and soaring oil prices.

[…]

What sense does it make to have a surplus of environmentally friendly Brazilian sugar-based ethanol with a yield eight times higher than U.S. corn ethanol and zero impact on food prices being kept from an American market by a tariff of 54 cents on a gallon while Iowan corn ethanol gets a subsidy?

[…]

The real scam lies in developed world protectionism and skewed subsidies, not the biofuel idea. [Bring on the Right Biofuels. Roger Cohen. NYT. April 25 2008]

Honestly, it is hard for me to say without looking at the data but I am leaning to his conclusion. Maybe, this warrants a short essay by itself.

Anyway, another go at the Doha Round, anybody?
