Predictably Irrational Chapters 9 & 10 – The Effect Of Expectation & The Power Of Price

In Chapter 9 and 10 (I combined them as they’re quite similar) of “Predictably Irrational” by Dan Ariely, the concept of how are expectations affect our decision making is discussed. We are not rational actors making choices in a vacuum but rather we are deeply affected by our expectations. If we expect a movie to be good, then it often is. This placebo effect is always to be found with prices. If we pay more for something, we value it more and get more from it. This creates serious problems for those who claim that market distortions will be corrected by market forces pushing a return to equilibrium. Ariely conducted an experiment involving free beer (I knew that would get … Continue reading “Predictably Irrational Chapters 9 & 10 – The Effect Of Expectation & The Power Of Price”

Predictably Irrational Chapter 1 – The Truth About Relativity

Predictably Irrational by Dan Ariely is a fascinating and deeply insightful book that is a pleasure to read and full of gems. It is bursting with interesting and ground breaking experiments that completely debunk many of the assumptions of economics. It will reshape how you view economics and how consumers react in real life, as opposed to in economics textbooks. It is a book I would highly recommend and should be considered a behavioural economics classic. In fact it’s so great that I couldn’t fit all I wanted to say about it into one post (or three) so instead I will summarise my favourite chapters (which is most of them) and highlight the important points they make. What is particularly interesting is … Continue reading “Predictably Irrational Chapter 1 – The Truth About Relativity”

The Flaw Of The Invisible Hand

Introductions to economics usually start with gushing tales about the magic of the free market. It is usually stated that the free market allows everyone to get the best quality goods at the cheapest prices. The magical invisible hand guides everyone to the best place without any unnecessary government intervention. Below is a link to a video typical of the kind. (I’ll ignore for the moment that it completely misrepresents what Adam Smith said). Its short and simple, but it is a simple argument. This is the typical free market argument with its claim that left alone it will bring the best world for everyone. So in the video it compares two bakers offering bread and the consumer chooses either … Continue reading “The Flaw Of The Invisible Hand”

The Mythical Laffer Curve

Conservatives everywhere condemn the use of tax increases for fear of the Laffer Curve. This is the idea that if taxes are too high, people will lose the incentive to work and therefore revenue will actually decrease. It is most famous for its counter-intuitive argument that a tax cut could increase revenue. Unfortunately there is little or no evidence to support this claim. History clearly shows that cutting taxes does not increase revenue. The Laffer curve is a political idea used to justify tax cuts for the rich. It is not based on sound economics. Most economists know the Laffer Curve isn’t true. An IGM survey of economists found that not a single one of them agreed that a tax … Continue reading “The Mythical Laffer Curve”

The Advantage Of The Minimum Wage

There is a lot of debate over the minimum wage. An internet search of the topic will return with almost unanimous condemnation of it. It is blamed for unreasonably pushing wages too high and causing unemployment. It is decried as a major cause of economic problems rather than the solution. However, these arguments are based upon over simplified ideas and graphs. Now, most of them look nice and are easy to understand, but they should be judged on how well they describe the real world. The simple fact is they don’t really. The main argument is that if a workers marginal productivity is 5 euro, they cannot be paid 6 euro. Now this presumes that the boss knows what the … Continue reading “The Advantage Of The Minimum Wage”
