Ghettonomics And Inequality

Average monthly income (horizontal) and spending (HIES, 2009/10) by income deciles*

What do wealthy Sri Lankans spend on? Foreign cars, iPhones, imported goods and travel. I call it Ghettonomics. Rappers representing the hood get out and spend all their money on luxury items, sold by already wealthy people. It’s not like Bentleys are made in Brooklyn. Hence, the hood remains poor. I think this is one reason why income inequality hurts developing countries.

Look at this chart of spending by income bracket. Until you’re earning about Rs. 20,000 a month (about $200, per household), you’re spending most of your money on food. Once you break about 30k, however, you have disposable income. Where does that income go?

TVs, phones, vehicles, appliance, and also condiments and better tasting food. Now, think about it. Where does that money go? I don’t know any TVs or phones made in Sri Lanka. Even mobile phone service providers are mostly foreign owned (Dialog’s holding company is Malaysian, Etisalat is middle eastern, Airtel is Indian). Vehicles are at best Sri Lankan assembled (Micro), but almost all made abroad. The government’s hefty 100%+ tax does pump money back into the country, but that’s not an ideal level.

Sri Lanka’s rich are living ghetto fabulous. I think. That, of course, is not in the data, in this case from the 2009/10 Household Income And Expenditure Survey. But it seems to make a bit of sense. I mean, we even import tinned fish and rice if you want to get into it.

This is not to say anything against imports. The question is inequality. I previously went over how wide income inequality is bad for sustained growth. What I’m trying to figure out is why. So here’s my theory.


Big money leaves the hood

Let’s take one closed system, say the Marcy Projects. Jay-Z is from Marcy, but once he made a bunch of money he couldn’t spend it there. He grew rich faster than the people around him, so he basically had to leave. It’s not like you can spend $10,000 on soul food and it’s not like that neighborhood makes luxury goods. If, however, Jay-Z and his hood had grown wealthy at similar rates, there would be products and services they could sell to each other.

While this type of inequality can have very visible positives (charity for example) it’s not that sustainable. Of course, it’s not like there’s any sanctity to any ‘closed’ system, I mean, if you want to get out of the projects get out. On a national level, however, people pay taxes and pool their resources for some sort of shared benefit. So, policy that balances inequality is within the ambit of good governance.

The (somewhat allegorical) Henry Ford model was producing a car his employees could afford. Hence, the market feeds the market. A certain amount of trade between discrete markets (ie nations) is beneficial,

Now this is dangerous because many countries react to this ‘threat to the nation’ by cutting off imports or imposing tariffs. This is like cutting off your nose when you have allergies. As much as I often wish for this, not helpful. I think the broader issue is inequality, and how to address that. Hence, perhaps making investments in health and education before big infrastructure projects, or at least at the same time. Such that you have the human capital to perhaps build your own highways or drill your own oil. Not for nationalistic reasons, but simply to lay a foundation for more stable growth.


Even before globalization, high income inequality meant that the wealthy would spend on gold and diamonds and pyramids and stuff that had little connection to the people around them. Royal families in Europe tended to be more closely related to each other than their people (the Windsors, for example, are German family by descent). Now what you get is a situation where they globally wealthy often have more in common with each other than their own national compatriots. US companies can get quite rich hiring people in China, and people in Sri Lanka can get quite rich selling stuff abroad.

Anyways, this is just a theory. All I’ve got data wise is the above which shows a rise in non-food spending and a confusing paper about inequality and import demand. Ghettonomics requires more research.

*The graph here shows the Sri Lankan population in deciles, the top 10%, next, etc. As the report says: In addition to the median value, decile groups are also ease the understanding about an income distribution, particularly the inequality of the distribution. The boundary values of the decile groups break a distribution into 10 equal size groups and the first decile holds the population 10 percent which the lowest values of the distribution are attributed to. So to obtain the range values of the household income deciles, all the households are arranged in ascending order according to the income and divided into 10 equal sized groups.

Note to readers of this blog- This is a classic case of tampering with graphics to drive across a point.
Note the variance in length on the x axis of the graph. Note the contraction of length from 40k to 53k and drastic contraction from 53k to 114k to give the visual illusion of exponential growth of ‘Other spending’. A more realistic graphic will show the real picture where spending ‘Other spending’ actually DECREASING after 53k.

Shame on you.

The x-axis is income deciles, ie, the poorest 10% of households live on an average of 6k a month, the richest 10% live on an average off 144k. So, yes, the Rupee averages don’t go 1,2,3, but the deciles do

There’s no manipulation here, it’s literally copied from the HIES data and graphed. Each point on the x-axis is a decile, it could be 1-10, but I though the average income would be more informative. My bad for not explaining the graph, at all. Added some details above.

Damian Poosa (2000-2014)

Our family cat Damian passed away last night. He was an American cat and it was fitting that he passed on the Fourth Of July. Damian was an ornery cat made happy by the love and care of my sister and parents. I brought him home on the day of my high school graduation (a stunningly thoughtless thing, in hindsight) and my sister and mother actually raised him. He then travelled back to Sri Lanka and had a great time till he got old.

How The BBS Attacks (A Tale Of Two Cities)

This seems to be the basic BBS gameplan (for fucking up everything we’ve worked so hard to build after the war). It’s a cycle of outrage, riot, fear, repeat. It’s like the eightfold path to not being a Buddhist:

Buddhism And Racism

Buddhism is not racist. The ideas and practice of Buddhism involve meditation, perception of impermanence and ultimately what we would call a renunciation of self. Being a Buddhist, however, is not just that. Being a Buddhist fundamentally involves taking refuge in three things – the Buddha, the Dhamma (his teachings) and the Sangha (the community of practice). As a Buddhist, this is why the violence in Aluthgama is so troubling. Becomes it comes cloaked in the colors of the Sangha. The main racists and instigators of mob violence are monks.

The Tragedy In Aluthgama

I haven’t written here in a while because, well, I guess I haven’t had much to say. I’m been writing about food and leisure at YAMU but, well, somethings gotten in the way of that now. In a way we could sense it because of the constant halal debate on YAMU, which is mainly a food site. That food issue in many ways has become a touchstone for the Muslim/Buddhist tensions rising in this country. Yesterday those tensions seemed to explode in Aluthgama and Beruwela on the Western coast. The racist BBS staged a rally there and then paraded thru the streets. This exploded into violence, attacks on businesses and homes.
