4 Ways We Are Not Rational And How It Affects Economics

At the core of economics (especially economics teaching) is the idea that people are fundamentally rational, self-interested, utility maximising individuals who make decisions after logically considering all the relevant facts. As these people know best what’s best for themselves, these decisions are optimal for society. However, one of the newest and fastest growing school of thought is the Behavioural School which uses the insights of psychology to show that this simply is not the case. These insights are sometimes viewed only in isolation or glossed over as minor trivia. However, when you put all the different pieces together, you see that the conclusions are far reaching for how the economy operates.

Do People Really Have Inflation Expectations?

A common feature of macroeconomics is to run models assuming that individuals in the economy have inflation expectations.

As a result, government policy lost its effect and unemployment rose. Since then, economic modelling and discussions of unemployment and inflation must contain some provision for what consumers expect inflation to be.

Ireland is well known for its links to alcohol and as a student drinking is almost mandatory for me. So what is the economics of drinking?

Macro Over Micro

Economics is divided into two sections, micro (focusing on individuals) and macro (focusing on the whole economy). However in universities the emphasis is heavily on micro to the extent that macro is often seen as simply micro on a larger scale. This is fundamentally wrong and ignores several points.

This focus ignores the fact that the best option for the individual is not always the best option for society as a whole. Continue reading “Macro Over Micro”
