What Economics Wants


So far, I learnt that everything we do is well-reasoned, properly justified and can be modelled using basic calculus and linear algebra. So well-reasoned across all individuals in fact, that it can be correctly and precisely aggregated. We optimise our choices all the time. We can perfectly predict the future. (How come astrologers are frauds when they make that claim but economists are geniuses?) Once we commit to an action, we make sure that we follow it through. All this just contributes towards making us the wonderfully regular, rational, trade-off talking people we are.

But that’s not all. In economics and other social sciences, we have built models for how we choose where to live in terms of access to education, the composition of the neighbourhood and a lot of other factors that I can no longer remember. Based on our identity, cost of education and employer beliefs conditional on social identity, we emit some signal. Based on this signal, we could be assigned some job that we supposedly want with some probability. Considering the amount of mathematics required for these important but relatively straightforward decisions we make, I’m frankly amazed that we manage to breathe without analysing ourselves to death.

I think students of economics should be charged the lowest possible insurance premium. Have you ever seen a reckless economist? We’re dull, boring, predictable and worst of all, rational. Insurance firms couldn’t ask for more. I bet they can’t find another category of people less likely to get into scrapes.
