What I mean to say

Challenging Orthodoxy, Part II: Rigor vs. Neo-classical Economics

This excellent post questions many of the assumptions made in neoclassical economics, which I have trouble accepting. I know comparatively little about economics compared to these guys, but I think right now you could classify me as an ‘orthodox lefty’ because I still use the basic neoclassical economic framework (can’t blame me – it’s all I’ve learnt so far!).

I think even neoclassical economics is inexorably moving towards incorporating some heterodox beliefs (I hate these terms, it makes economics sound like a religion) – behavioral economics is especially exciting. But it will be a long time before anything other than the standard neoclassical models are taught in undergraduate economics. Darn it all.

Get real

In Economics Departments, A Growing Will to Debate Fundamental Assumptions

This NYT article sums up my pet peeve with economics – those stupid assumptions. Free trade is unequivocally good! Government intervention is the root of all evil! If your economics doesn’t have maths in it, it’s not real economics! Everyone is rational!

I wish I had the knowledge to analyze these assumptions for myself, but right now I need to focus on learning the fundamentals. I’m currently reading The Truth About Markets – thank goodness John Kay isn’t a rabid neoclassical fundamentalist.

I love this guy

Look North

Douglass North’s Autobiography

Finally, someone who thinks the rationality assumption in neoclassical economics is questionable. And finally, someone who realizes the importance of institutions, adaptations and beliefs as catalysts for economic growth. For something that’s supposedly so controversial (well, not exactly controversial, but many economists prefer to just pretend it doesn’t exist), it’s amazing at how intuitive North’s ideas are. Like you’ve known it, deep inside your heart, all your life. But on the other hand, they are absolutely overwhelming – how on earth do you incorporate this with modern economic thinking? How could you ever develop a working model that can account for the myriad of institutions, beliefs and integrators out there? How can you use maths (which is an integral part of neoclassical economics) for this? I’ve got no time to comment on the links, because it’s way past my bedtime – but dear God, what I wouldn’t give to be Professor North’s student!

(And the guy used to be a Marxist. There is hope for me still!)

The best job in the world? (no pun intended)

New condom roles ‘offer job satisfaction’

Who wants to be a condom tester? Is this the best job in the world? There’s no pay – but

successful applicants will receive a free $60 selection of Durex products and will be required to provide the company with honest feedback about the products’ performance.

One of the lucky 200 testers will win a $1000 bonus.

Although there’s no pay, you can bet that Durex will be inundated with the resumes of virile young men, all eager to snag the ‘world’s best job’. If it was any other job, it’s unlikely anyone would give it a second glance – because the pay is pitiful. But being a condom tester has a significant compensating differential – there are other non-monetary rewards that make the low pay seem worthwhile anyway (eg the satisfaction of bragging about the job and other things that I will leave to your imagination). Compensating differentials explain why priests, nuns, teachers and nurses get such low pay – the satisfaction they derive from their jobs compensates for their low wages (okay perhaps I shouldn’t include teachers in there, but let’s just assume teachers really love teaching). I know it’s sinful to compare condom testers to nuns, but hey, I need to make economics interesting :)

However, there are a few differences between condom testers and nuns – for one thing the supply of condom testers will always exceed the supply of nuns, because of the nature of the two jobs. Any man* (yeah all of them, since we now have Viagra) can be a condom tester, but not everyone has the strength and fortitude to be a nun.

Do the low wages indicate a lack of demand for condom testers and nuns? For condom testers, I would say demand is pretty low and very elastic. Why? Well, even the CEO of Durex could become a condom tester – they don’t need to hire other people (IMHO this whole condom tester thing is just an elaborate marketing ploy – the latest version of giving out ‘free samples’). Since it’s so easy to find substitutes for condom testers, labour demand elasticity is high and that’s why the pay is so low. But what about nuns? Is there demand for nuns? Well yes – churches and religious orders need nuns to run schools, proselytize, help priests look after the congregation, etc. The elasticity of demand for nuns is very low too – there are few substitutes for nuns (although it is higher than it used to be, as teachers can be hired to run schools and volunteers can do missionary work – but they are still needed to run religious orders). As mentioned before, the supply of nuns is very small and very inelastic – few are willing to give up all worldly pleasures for a life devoted to serving God. So, with inelastic demand and supply, how come nuns’ wages are so low? They don’t need the money, of course. Their transfer earnings (the amount of pay needed to keep them in the job) is very low, thus almost all their pay is economic rent (money over and above transfer earnings – a bonus). Simply put, even if they had to work for free, nuns wouldn’t be doing anything else. They truly are amazing people.

(You could say condom testers would still be having sex even if they weren’t condom testers (hence their transfer earnings is zero and everything is economic rent), but a nun’s work and lifestyle is much harder, which is why I salute them :) )

However, not all jobs that have low transfer earnings and high economic rent pay a pittance. Take football players, for instance. These people are really crazy about football. They love it, and they’re good at it. All they want to do is play football for a living. It’s all they think they can do. Even if football players were paid as much as nuns, they would still play, because they love the game (same concept as struggling writers and actors really). So why are they paid millions of dollars to play? The answer, IMHO, lies in the differences in productivity. A football player is more productive than a condom tester or a nun, because when he plays, he is watched by millions of fans all over the world (Caveat: We’re talking about the best players in the world here, not third division people). Thanks to the wonders of technology, a football player generates millions of dollars in revenue for sports companies and his club through advertising and sponsorship contracts. He doesn’t necessarily work more than nuns or condom testers, but the fact that he can reach more people increases his labour productivity. A 90-minute match exposes him and whatever brand he’s endorsing on his jersey to millions of fans around the world. How many people can a nun reach in 90 minutes? How many different condoms can a tester try in 90 minutes? You get the picture :) The higher one’s labour productivity, the higher his wage.

So, what’s the best job in the world? You decide :)

The World is Not All That Flat And Never Will Be

Note: In the course of writing this post I have contradicted something I’ve said previously. I am very inconsistent in my beliefs, and writing this has only made me more aware of how much I have yet to learn. This pro-trade post looks at free trade and globalisation from a very narrow point of view – that of the Common Agricultural Policy and the ‘dumping’ problem. I have a tendency to use human self-interest to explain everything – and this has made me aware of the glaring inconsistency in what I’ve written on this blog so far. In previous posts I lashed out at people who scorn government intervention; I criticize government protectionist policies in this one. I neglected the fact that governments are made up of normal human beings, who have, first and foremost, their self-interests at heart. I thought of deleting this post, since it is quite pointless, but decided to publish it in the end, because it’s important to record my thought progression throughout this project.

Okay, I’ll admit this – I spend far too much time agonizing about poor jobless workers instead of using my brain to think about matters rationally. But let’s get something straight – the rational part of me (let’s ignore the emo-ing, menopausal part of myself) supports free trade. In theory. Why do I emphasize ‘in theory’? Because to me, trade with no barriers at all is impossible. It is politically impossible. Not everyone has studied economics, not everyone knows about Ricardo’s theory of comparative advantage. Some voters will always oppose free trade if it is in their interests to do so. Remember my previous post about how I oppose government price ceilings on roti canai but support government subsidies for multinationals, despite both price ceilings and subsidies being examples of market distortions? That’s exactly what I mean here. A dairy farmer in Europe will be delighted to buy cheap Dell laptops made in China (because he saves money), but will be incensed if the EU allows Australian dairy companies to export milk to Europe. You can’t expect him to sit back and say, “Oh yes, I must allow highly efficient Australian dairy farms to export milk to my country so that my fellow countrymen can enjoy cheaper milk, while I go out of business because I am less efficient than my Australian colleagues! I’m not worried because I can get a job driving a Fern-Leaf delivery truck! All hail the power of market forces!”

No rational dairy farmer would think like that, because as a profit maximiser (assuming he is one), his self-interests come first. You know what he’ll do? He’ll round up his fellow European dairy farmers, form a huge, powerful agricultural lobby and pester their politicians into introducing protectionist policies to prevent Aussie milk from ever reaching European shores. That’s the Common Agricultural Policy for you, which makes up almost half (or is it more than half) of the EU budget, and is one of the worst examples of trade protectionism around.

If we want free trade to work the way it should be, we should get rid of everyone’s protectionist policies. Not just those of the Third World countries, but those of the First World as well. But you see, it’s never going to happen as long as politicians are the ones determining economic policies. Politicians (well, the vast majority of them) always put their self-interests first. Just like normal human beings. It is rather unfair to expect anything more of them (of course there are a few exceptions, whom I fervently admire). The agricultural lobby is powerful and rich. They are some of the biggest political campaign donors out there. Do you seriously think politicians are going to bite the hand that feeds them? Get real. Yes, we know that free trade is not a zero-sum game. But as long as there are people who see it to be zero-sum, it will be. Why? Well, let’s take the Common Agricultural Policy again as an example. Under this policy, European governments set the minimum price for agricultural produce like milk, and it is illegal to sell produce below this price (not that farmers actually want to). When you raise the price of a good above its equilibrium price, you’re going to get a surplus – supply exceeds demand. Under normal market conditions, when a surplus occurs, the price of the good will automatically fall as farmers cut prices to sell more goods. Eventually a price will be reached at which supply equals demand – the market equilibrium price. All is at peace.

But under the CAP, governments guarantee that they will buy up any surplus produce from farmers at the artificially higher price set by them. For the farmers, it’s like winning the lottery. It’s no wonder that this encourages farmers to produce as much as possible, safe in the knowledge that all their produce will be sold, and for a handsome price too.

What happens to the surplus farm produce? That’s where ‘free trade’ comes in. The EU bullies hapless Third World countries into lowering trade barriers against EU farm produce so that the European governments can sell their excess produce to Third World countries – at a fraction of the cost price. This is called dumping, and it is responsible for driving many Third World farmers out of business. How can you possibly compete with EU farm produce that is sold below cost price? What’s worse, Third World countries are heavily dependent on agriculture – the effects of dumping can be disastrous for them, since their economies are mostly agriculture-based. At the same time, these poor countries are not allowed to export their produce to EU countries, because the EU imposes tariffs on them. Isn’t it nice to be a big and powerful country?

This is not a rant about how life’s a bitch and the world is so unfair. My point is that free trade as it is meant to be is impossible because the vast majority of humans have only their self-interests at heart. You could say that I have a fatalistic outlook on things. Not really. Perhaps if more people studied economics, if more people believed in the theory of comparative advantage, things will change. The key is to appeal to people’s self-interest – if people believed that free trade would benefit them directly, then they would support it. But there will always be losers from trade, and I’ll wager they’ll do everything in their power to stop it. What we could do is empower those who can benefit from free trade, give them a voice and hope they make more noise than the naysayers so that the politicians will sit up and take notice. Perhaps they know all about comparative advantage too – maybe even more than you and I. But they have an election to win, and that changes everything.

Sad and Disillusioned

I think I’m not cut out for economics. I’m too much of a socialist. Heck, when I took the Political Compass test at politicalcompass.org for the first time, I was practically a raving communist. After one and a half years of A-level Economics, I retook the test and am now classified as a centrist, but on the left side. But deep down inside, I care more about equality than efficiency. Maybe it’s because I don’t understand the concept properly. Look, I don’t give a damn about the efficient allocation of resources, as long as I have a bloody job. I resent people who think that government intervention is the deadliest of the seven deadly sins.

But I contradict myself at times. I get mad at the government when they try to control the price of roti canai (a local delicacy, sold by hawkers everywhere; monopolistically competitive) while allowing monopolies like our cable television network to increase prices as much as they want. At the same time, I get mad at people who think that government subsidies to multinationals is wrong because ‘it distorts markets’.

See, I respond to incentives. I’m always looking at things from my point of view, not objectively. To me, roti canai is a small fraction of my expenditure and any increase is unlikely to have a big impact on my spending. So I’m happy to let market forces determine the price of roti canai. But I want multinationals to invest in my country, because I need a job when I graduate. I’m not being objective. And I get angry too easily. I’m a rebel without a cause.

Sorry for the angst-ridden post.
