Where can i read about other schools of thoughts?
I know there's the austrian, orthodox and others but I'm not sure what they're on about.
edit:Also, who was the economist who said that the economy functions best when everyone acts to benefit themselves only. Or something like that.
Well I suppose this depends on what you mean....
I would argue that keynes if he were alive today wouldn't be a keynesian.... Probably in the same way as I dont think that Marx would be a communist.
The Austrian school essentially advocates for the free market. They argue for limited government (other than for a few things like defining property rights) etc. They are purists and dont tend to compromise too readily on their way of thinking. Subsequently they inspire a lot of libertarians etc. Friederich von Hayek is the key guy to read up about but others include Ludwig von Mises etc. These guys are often refered to as classical liberals. If you want to read up more about them, check out
www.cis.org.au The CIS is a large Australian think tank dedicated to classical liberalism. If you are super keen go and read the road to serfdom by Hayek (probably the most famous of his books but not necessarily considered his best).
A similar school is the Chicago School whose figurehead was Milton Friedman. Milton Friedman is the most influential economist of the last 40 years and is notable for inpiring Margaret Thatcher and Ronald Reagan to implement many free market reforms throughout the 80's. The Chicago school is also fairly free market based, but not as pure as the Austrian school. For example a key theory that came out of the chicago school was monetarism (that involves growing the money supply at a rate equal to the growth in goods and services). Monetarism is a free market theory in the sense that it is a non interventionist form of monetary policy (i.e. not aimed at stimulating economic growth) however the Austrian school would argue that having a central bank that issues currency is an example of the government overstepping their duties. Whilst monetarism is now a defunct concept (mainly because the velocity of money changes and it is too hard to achieve in practice) many of the concepts remain today. For example pursuing a low inflationary monetary policy is a consequence of Friedmans long run phillips curve. Miltion Friedman was a very influential man. A great book to read is Free to Choose (if you are lazy it is available as a television series but it was filmed in the early 1980's so its getting a bit old now). Here Milton Friedman provides an eloquent arguement for free market policies.
In england the main debates tend to go between the London School of Economics and Cambridge although neither tend to be refered to as a 'school of thought'. Cambridge tends to be the defender of keynes (as he came from cambridge) however in modern times keynesian theory has been provided with more context and it is less ideological than it may have been in the past. LSE is more in the vein of the Austrian and Chicago schools. Afterall Hayek was an academic there for a period (before going to chicago funnily enough).
That sort of ends the story of schools when it comes to influential modern day schools, but going throughout history there have been many different schools. Prior to Adam Smith there was the mercantalists in england who advocated against free trade and the pysiocrats in France. There was the marginal revolution (JS. Mill) etc but these are more kind of periods reflecting the evolution of economics rather than schools.
As for your edit:
Adam Smith was the man who said that.
Basically his statement was that the only way you can make yourself better off, is by making someone else better off.
Refering to the fact that if you want something, you need to do something for someone else in order to earn an income to buy what you want.
