In the same thread, we discovered that a student at Oxford doing E&M, claiming to have a specialty in development economics, didn't know the names and theories of the founders of the discipline--which I had covered in my economic history course. Presumably, he's been doing math problems instead of actually studying a framework through which to understand economic development.


Shady, even by your standards, this is a disastrous piece of reasoning.

1) You 'presume' that he was doing maths instead of learning names of founders. Becuase you write 'presume' I can only presume that you plucked that out of the air, to satisfy your own hypothesis. There is no reason to think that he was spending his time doing maths, other than to fit in with your own purposes.

2) Why should he know the names and theories of the founders of the discipline? You say that you covered it in economic history - this is perfectly understandable, because that is economic history - but there is no reason for the contemporary student to necessarily know them. You yourself was arguing this very position in reference to EH Carr in the IR thread.

3) As part of E&M at Oxford, development will only ever be 1/8 of the degree - so it is not at all true to say that he is a development 'specialist', and further excuses him from not knowing the names of the founders.

4) It's debatable that you need to know the names of founders of a topic, and their outdated theories, in order to understand and study the topic properly.

As usual, there was a lot of rhetoric but very little logic in your post.

Maths is a great subject, probably the most respected, but this doesn't mean it should be abused. Economics is NOT maths. Econometrics i accept needs to be mathematical, as its empirical by nature, but economic theory doesn't.

Sure you need maths for economic theory. Economic theory spends a lot of time talking about the relationship between variables. Invariably, because we deal with nominal variables (ie inflation/unemployment, etc) this means that these variables can be plotted on a graph. This then means that you can justifably use mathematical tools, eg calculus, to manipulate and analyse these graphs. This is only a very basic example, but you clearly have no idea what you're talking about. Some amount of mathematics is essential in economic theory.

Shaun A
This can be seen in the fact that modern economic theory, is failing to explain the threshold, 10%, of empirical data. This is really sad.

As I said before, I plain reject this figure, it's a complete fabrication, and since you are the one using it, it is your responsibility to present it as a reliable source. You haven't done so - apparently you 'read it somewhere on a forum'.
Shaun A
I remember my economics teacher saying to me, the mathematicization of economics is very recent, so when i say economics is useless, i'm referring to modern economic theory, i.e neo-classical economics, not the old-school classical theories, which make perfect sense.

You are just name-dropping theories, or rather, families of theories, without any grasp of what goes on in them; you're just displaying your ignorance.
Shaun A
We all know why this happening, where not stupid.

No, but apparantly we are to stupid to spell 'we're' correctly.

Shaun A
Economics academics have an inferiority complex toward science. They want to be classed as a science, not a social science, they'd give everything they have for this.

This is pathetic and absurd. My first-year macroeconomics lecturer was on the Bank of England's MPC, at the forefront of economic policy. To say that he is jealous of not being a science is absurd and insulting, and frankly not true.
Furthermore, a sematic point. What is a science? What does it mean to be a science? All sorts of disciplines can be legitimately called sciences, without necessarily reflecting on themselves as disciplines. In the states, the call politics 'political science'. All I am saying is that you are taking an extremely dogmatic and narrow definition.

Shaun A
Unfortunately, this is never gonna happen, unless that 10% figure moves closer to 90%, while maintaining the mathematical rigour. But we all know thats not going to happen. Tell me, fellow economists, why in the purple green hell are third year economists, solving differential equations all year, this is a joke.

Well, the economists at my university do a hell of a lot more than just solve differential equations in their third year. Again that is just ridiculous, and not true at all.

Shaun A
I know for certain, it's easier for the mathematicians and physicists to get into postgrad economics schools, than econ grads. Thats hilarious. I've even heard that quantum physics and chaos theory are being applied in economics. You guys need to get a grip of yourselves, this is getting embarrasing.

As halfoflessthan50p writes, this is perfectly reasonable.
Shaun A
Further proof for my argument. The modern new area of interest in economics 'econophysics' (the applications of physical theories to economics). For the love of God, would you guys stop embarrassing yourselves.

For the love of God, I would have thought a mathematics student would know how to use the word 'proof', now it is you who should be embarrased. You could do with a few elementary logic classes, or at least just going to your lectures.

Shaun A, given you know so little about economics, you should learn to keep an open mind about things - it will help you in life, in the long term.

Not my words, they're the words from Davetherave, a LSE Econ grad (i think)


okay, fair enough

What a crazy and stupid point. So your telling me failing to explain the threshold, 10%, of empirical data is acceptable? Your correct in saying it provides a general model. But unlike physics and chemistry, economics is not a science, so this general model is insufficient. It only accounts for less than 10% of the whole story. Whereas scientific theories, account for the whole picture, and are refined smoothly in different cases.


Its not a stupid point. And chaos theory is physics, its accepted scientific fact. I'll try and explain. In chaos theory you have something called sensitive dependance to initial conditions (or The Buterfly Effect.) It says that a system thats controlled by deterministic equations (that just means equations with no random inputs) can be unpredictable but not random.

For example they think the weather is a chaotic system. So theres equations that describe the way it behaves but they're nonlinear so you cant use them to predict how the waether evolves with time very effectively. If you worked out the underlying equations for the weather system you wouldnt be able to predict how sunny its going to be 10 years from today but you would know all the variable that controlled the weather and you'd be able to do things like stop droughts, predict the effect of global warming on rainfall, average temperature in different parts of the world etc.

If you worked out non-linear equations that described an economy you could use them to quantitively predict the effect of increasing/decreasing taxes, salaries, commodity prices etc I imagine. Its hard physical theory, not vague quantitative discussion like you presume.

I dunno how well i explained that, read Gleick

Most models in economics are based on a million of assumptions, this is crazy. One of the most common ones being, homogeneity. Do you know what that means? It means everyone is identicle! They behave exactly the same, i.e utility maximising (this also applies to stupid people with no qualifications, and they assume they would start using game-theoretic models, to determine optimal strategies, this is ludicrous! The 'art' behind economics has been 'chucked in the bin' by economic researchers, and instead they've assumed humans behave like robots.


Maybe that is a failing of economic theory, i dont know much about it so i wont pretend. But alot of physical theories are simplified models of reality really. You presume all molecules are hard spherical shells in theories about gases, equations of state etc and you come out with equations that describe nature perfectly. And back to chaos theory. You'd think modelling population change would be impossible because theres so many variables and each animal is different and ahs different experiences in its life but you can do it for lemmings and moths. It turns out that things like differences in individual animals are just noise really and the underlying dynamics are simple (but non-linear) stuff.

You might be right about utility maximising but its not necessarily bad scientific methodology to do it like that.

At least a few people understand whats going on, if you still don't understand now, you'll never understand


if youre gonna be patronising you can **** off please

Sure you need maths for economic theory.

Of course you need maths, i didn't dispute that, i said it was way way too much, and it was obvious they were trying to make the subject appear scientific. I've read econ books, where the introduction, explains the 'scientific method', simply embarrassing.

tom391

his means that these variables can be plotted on a graph. This then means that you can justifably use mathematical tools, eg calculus, to manipulate and analyse these graphs.Some amount of mathematics is essential in economic theory.

Note i said the maths in econometrics was acceptable. Did you actually read my post? Maybe the maths has got to your head :biggrin:.

I tried to be nice, and only name some areas of economics that were useless. But if you want me to say it, i'll say it, all of modern economics is useless, better?

Why don't you have a look at my analysis of her post, which clearly shows in numbered reasons why I think her post was fallacious. Just because someone has a posh degree doesn't mean they don't make mistakes, or illogical posts. Why don't you read what I had to say and make your own mind up based upon that? At the moment, your mind already is made up, and you are therefore blind to any reasoning.

no i think you are allowed to do a language course. im doing one atm but it is part of my course (a year in europe). there are other people from different depts taking language in my class as wel.

Okok, I know you are in Maths, ya me too.

So you are allowed to do language course even though it is not written in the Maths prospectus.

How many can language moduels you do?
What are the common languages taken by Maths student?
Is the course-load for a language course more heavy or less heavy than a normal maths course?
is the grading for language harsh?

Also, I believe that the maths with a yr in europe is a modified course that replaces some of your maths module with languages to prepare you all for the year aboard. in a sense, it is pre-arranged for you.
I am too lazy to respond line by line. I will briefly say that, in order to study development economics properly, one certainly needs to apply the theories that exist and examine their applicability to various examples. To not know Arthur Lewis (who won a Nobel Prize in economics!), yet be studying economics at a great university like Oxford, is a major problem. And the user actually did say that he felt bad that he didn't know about these theories and that he was, in fact, doing more mathematical development economics.

Anyway, we concluded in that thread that what used to be economics is now economic history and political economy (which is pretty much what I study), and that what is now called economics is econometrics/math/physics/statistics.

I'm certainly not stupid; this is just my opinion. Social sciences have an important place in both the academy and the real world, but pressure to turn them into "real sciences" is taking the "social" bit out. And then we understand quantitative models instead of human behavior and group action. It's even happening in politics and IR; in my last year at Stanford, they awarded a post-doc fellowship in the Center for International Security and Cooperation to a mathematician. I believe in coordination of fields, but what we're seeing is colonization, and I think it will lead to problems in the future.

This had happened to Physics. It is reasonably fine to still see how the world works under Newtonian physics, but once things get complicated and abstract and do not correlate to experiences of everyday life, the mathematics needs to come in, as in the case for Quantum Mechanics. Studying it would just be reduced to studying the equations, since the actual behavior of QM is contradictory to our everyday experience.

I believe that in a business degree, people would learn about theories of advertising. But just look at your right, that banner of Ads from Google. Like it or not, they are all done using Maths/Programming. Google generates its revenue from advertising. In a way, it is an extremely successful advertisement company, but one that builds more on math, rather than business knowledge.

Also, seeing the way how Gasparov lost to Deep Blue, it makes sense that the same thing would have to trading in the future. 50 years ago, no one would seriously believe that a computer would play better chess than a human being. Now, the best chess player would be a group people who are very good in chess AND programming, coupled with a super-computer. It would brutally crush 99.999% human beings with ease, and of course, crush the best of human beings.

Haha I am pretty ignorant on some things but that's just my view on the general thread of the world. Feel free to correct me.

Are you really sure about that? I was pretty interested in chess a while back and I remember that the really great grandmasters usually stalemated vs computers or some silly move from the start would cause either one to win by a VERY small margin. The computers can only know every single move historiacally made (they're programmed to know), this is usually enough for beating 99.99 % of humans, but they wont "crush" the very best.

One can actually watch live chess sometimes, the elite is pretty amazing.

Haha I don't claim to know a lot about chess, but from wikipedia
The system derived its playing strength mainly out of brute force computing power. It was a massively parallel, ... It was capable of evaluating 200,000,000 positions per second, twice as fast as the 1996 version. In June 1997, Deep Blue was the 259th most powerful supercomputer, capable of calculating 11.38 gigaflops... The Deep Blue chess computer which defeated Kasparov in 1997 would typically search to a depth of between 6 and 12 ply to a maximum of 40 ply in some situations

Deep Blue, with its capability of evaluating 200 million positions per second, was the strongest computer that ever faced a world chess champion. Today, in computer chess research and matches of world class players against computers, the focus has often shifted to software and creating more intelligent chess programs, rather than using brute force computing power. Modern chess programs like Rybka, Deep Fritz or Deep Junior are more advanced than the code used on Deep Blue. In a recent match, Deep Fritz vs. Vladimir Kramnik in November 2006, the program ran on a personal computer containing two Intel Core 2 Duo CPUs, capable of evaluating only 8 million positions per second, but searching to an average depth of 17 to 18 ply in the middlegame.

The software is getting a lot more advanced. Imagine running Deep Fritz on a computer like Deep Blue?! :s-smilie: Brutally crushed.

Also, they can "think" I guess, by elevating the positions and giving a score on possible future moves.

Seriously though, an A in AP calculus is a joke. It proves you are good at learning and applying simple methods.
I got 7 in my Danish A1 course and a 6 in my English A1 course (having had no formal teaching in english prior to beginning IB1) in International Baccalaureate, so it disproves that I'm not extremely good at composing essays and thinking critically about texts.

What argument do you support?


That economics lacks mathematical foundations and is generally quite vague.
Its lack of mathematical foundations doesn't make it vague. It's a social science. It is concerned with the behaviors and actions of people and other social actors (governments, corporation, etc.). It's not meant to have a mathematical foundation; that's the problem with the direction of the field now. Yes, some math needs to be involved in order to draw a conclusion from data or support a theory. But it's still based on actions at the end of the day.

I would agree.

Erm... by parallel, you can study the theories behind conduction, convection and radiation simply by using words like what the social sciences are today. (i.e., how the molecules collide with each other and heat is spread for conduction ...)

The quantification of physics is one of the biggest advancement of the field.
But physics and human action are totally different! Why does the market slow down at the end of December and rally at the start of January? Because of Christmas holidays. The answer to that isn't to do math problems!

I agree with Shady Lane, as surprising as that might be coming from me :cool: . Physics/maths can't quantify everything, though it does a damn good job in some cases, it still works on probabilities when it comes to human behaviour (i.e. given input A and input B, the probability of a given output from a human would be C etc). That's not to say social sciences can predict it any better. Human actions can't be expressed in a mathematical formulae, but then they are also hard to determine through social sciences themselves too. At best, we need to keep to judging by "herd mentality" and building models, where there will always be exceptions who won't adhere to it. The best models are the ones where you can collaborate mathematical modelling with social understanding.
