    Haha, I haven't added anything of substance in some time... I will start posting my own thoughts whenever I can be bothered to.

    This probably belongs more in my "math" thread, but I will post it here.

    A cool thought experiment in metrics:

    assume that n=40 (population=400), μ=658

    we can compute y bar through:

    And let's assume that we get an answer such as 650.


    I will now pose a question... since our sample mean was drawn from n=40 there must be many different values for y bar, how many possible values are there?

    Well, the answer is a lot of fucking values:

    (400 40) = 400!/ (400-40)!40!

    After this, we could theoretically compute the gaussian(s) for the distribution of possible sample means which gives us a neat proof of the intuitive idea that the sampling uncertainty decreases as n increases. In other words, as n increases, the distribution of Yn bar tends toward the population mean.

    Definitely should be in the maths thread this. Unfortunately we don't have one; we only have a singular math thread, which means we are not allowed to do more than the one sum in there that has already been done.

    I see what you are saying above. Well mostly. Is this the standard proof for sample size increasing certainty? Or just you thinking about it?

    Nah, just thinking about it... it's pretty basic but it gets the job done imo.

    This is the slightly more nuanced proof, but I (obviously) prefer mine:

    Dear Tom,
    I am not sure which decision you wish me to evaluate: the decision to pick your A-levels without decent advice, or the decision to pursue a mathematical subject with no mathematical talent. Neither looks smart. You have theorised on the basis of neat concepts without any real-world knowledge – in some ways, ideal preparation to be an economist.

    This is more political economics, which is more what I'm into these days. It paints a bleak picture of the landscape in Europe. I suppose the picture already exists, and this is one analysis of it.

    Anyways, thought I'd share, since I've started feeling guilty about still not reading your thread properly.

    Could also post stuff about game theory, but it is better placed in the math thread.

    Some Open Economy Macro:

    The Impossible trinity



    Summation of the argument (through contradiction):

    - Some may argue that having a fixed exchange rate policy, monetary policy & free flow of capital at the same time is a necessarily good thing.

    - However, this is wrong in the view of macroeconomics, it is argued that this sort of reasoning violates the "impossible trinity" (aka policy trilemma).

    - This occurs where there are three choices which the government cannot simultaneously adopt. It is argued that they should only adopt two of these three (simultaneously).

    - The three choices are : Fixed exchange rates, free capital movements & setting their own interest rate.

    If country A tries to choose all three at the same time, the following happens:


    - If A tries to lower it's IR in order to stimulate their economy during a recession. In order to do this, they must increase the money supply which in turn decreases the IR.
    However, when the IR of A is lower than that of its trading partners, everyone will want to put their money overseas due to free capital movements.

    - So they sell their own currency on the foreign exchange market and buy foreign currency.  However, this increases the supply of country A's currency on the foreign market, creating a downward pressure on their currency.

    - Since the government of A wishes to maintain a fixed ER, it will have to sell foreign currency from it's reserves to buy back it's own currency, increasing the demand for their currency.

    - However, if govt. A keeps doing this, it will run out of foreign reserves & has lost autonomy over its own interest rates.

    This is a very good graduate level text regarding the history of economic thought. It is surprisingly succint for its size.
    Currently halfway through, I've been meaning to develop my understanding of political economy for some time.

    Alfred Marshall, arguably the figure most responsible for the creation of neo-classical economics, commented in a letter on the relation between mathematical and verbal arguments in his field. He explained that he worked his arguments out mathematically to make sure they were right. Having done so, he translated them into English. If he could not translate them into English, he burned the mathematics.


    This approach is needed again. Economists try to bully other social scientists with their "mathematical prowess" but crumble in front of actual mathematicians.

    The last few months have been pretty fucked up to be honest, I've been indifferent between taking the train to work and throwing myself in front of it. Though I'm feeling better now, also thinking whether or not to do a masters.

    If you want to know why the current modus operandi of mainstream Economics is (analytically) wrong, Keen has a great crash course in Non-Equilibrium Economics.

    (It gets quite mathematical towards the end)
