The study of economics is often mistaken for a highly mathematical subject best left to PhD academics. In reality economics is a logically intuitive subject describing the behaviour of exchange within a society, which is well suited for any acute observer. Calculus and statistics are but tools to measure direction and degrees of relatedness between stimuli and behaviour. Behaviour is a function of motivation and incentive. And so if one understands the motives and incentives then outcomes can be predicted with a high level of probability.
