Book Review - "The Logic of Life: The Rational Economics of an Irrational World”

"The Logic of Life: The Rational Economics of an Irrational World” by Tim Harford. In this book Tim argues that rational behavior is more common than most people believe. Rationality means that rational people (and he believes that most of us are rational, the majority of the time) and simply “respond to incentives” When something becomes more costly or less convenient we will tend to do less of it. While an activity that becomes cheaper, easier or more beneficial we’ll tend to do more of it.” He provides a number of examples, including examples from gambling, smoking and dating. A couple of the more interesting examples include the following.

  • Economists have found that advertising for nicotine gum seems to have encouraged the percentage of non-smoking youths to try out smoking (because they believe that there are new options to help them stop if they get hooked, so it’s a less risky proposition for them).
  • In cities where men are particularly wealthy, women are plentiful. It seems that the motivation in these cases is two-fold – find a man and ensure that he will be a good provider. (whereas they number of men in Alaska greatly exceeds the number of women, but the number of wealthy men in Alaska is far less common than other states across the US.
  • One of the points that’s made to prove the limits of our rational behavior is that of American’s anemic savings rate for retirement. A generation ago the primary responsibility of retirement savings was the responsibility of our employers. Now we’re being asked to decide how much of our current, income should be saved for our future needs in retirement. And we simply don’t have experience with problems of that complexity, and many of us are going to live very different lives in retirement than we enjoy during our working years.
  • For small business owners, this book should help to make the types of product and service tradeoffs that our customers are likely to accept, easier to anticipate as we understand their underlying decision processes. Where possible reduce the prices and when you can’t do that, work on ways to make things more convenient and more beneficial for your customers. I think about the transition that service stations or gas stations made over the last decade or two. Gas stations couldn’t find sufficient value to support the price premiums that they were charging on their gasoline (we didn’t really need someone to wash our windows, check the air pressure and oil every time that we filled up), so the profit margins in gasoline were driven down to the point that many companies couldn’t stay in business. Can you identify a full service gas station in your city? What kind of gasoline price premium do they charge per gallon of gasoline for that service? – (it’s 5 or 10 cents per gallon in Boise, where I live) When did you last go there for your gasoline fix? (never, is my answer). Now gasoline is an additional function that convenience stores provide – although the prices of the milk, soda and potato chips are more there than they are at a supermarket, most of us are willing to pay the premium on certain occasions. And viola – an old business is converted into a new business that provides greater convenience than going to two stores to accomplish the same tasks. Just a little food for thought, Chris
