Economics in Two Lessons: Chapter 4

Thanks to everyone who the first three chapters of my book, Economics in Two Lessons. I’ve learned a lot from the comments and made changes in response to some of them. These chapters have been a bit abstract, but now I’m moving on to some applications, which might be more interesting for some readers. Here’s the introduction to Part II

Lesson 1, Part II: Applications

The economic analysis showing how market equilibrium prices reflect the opportunity costs facing producers and consumers is elegant and, for a certain kind of mind, convincing.

For most of us, however, it’s more useful to see how the logic of prices and opportunity costs works in particular cases, sometimes in ways that conflict with strongly held intuitions. This will also give us more insight into the ways in which prices can fail to reflect opportunity costs for society as a whole, some of which we will examine in Lesson 2.

Now here’s the draft of Chapter 4:Lesson 1: Applications. Again, I welcome comments, criticism and encouragement.

  1. On airline salaries – in the US, it is not just the workers without specialised skills who are badly paid. A typical pilot’s salary is around $30,000. How can the airlines attract pilots by paying so little? They can because many if not most commercial pilots are retired air force pilots and they get an air force pension, so they are content with the small salary. There is a real sense in which the US Government subsidises the costs of airlines (salaries and training costs), so deregulation has not been as pure as the text says.

  2. The airline example you describe is a very good illustration of the forces at work whereby deregulation at the product level has impacts in the labour market to the detriment of the workforce. It is worth collecting these examples.

  3. Hi John, I wonder if you’d consider including a diagram e.g. a decision tree, to illustrate opportunity cost? I appreciate this may not be your ‘house style’, but I have found them useful for following the lines of reasoning for calculating opportunity cost. I confess I got a little lost in the mixture of historical detail and opportunity cost decisions in the airfares example. The rest of the chapter re the College and advertising case studies were very illuminating.

    Hi Tim,

    I’m not averse to diagrams, but I’m not quite sure what you have in mind. Can you point me to examples of things I could adopt or adapt?
