Economics isn't as highfalutin' as the jargon makes it sound

Ross Gittins has a very nice piece in the SMH today, with some kind words about Economics in Two Lessons which he recommends as “the best book to introduce you to economics”. Ross says that the crucial concepts in economics are: Opportunity cost (of course!), the Invisible Hand (roughly, my Lesson One), imperfect competition, market failure and externalities (the microeconomic component of my Lesson Two).

His final para gives the lie to those who imagine economists oppose action to save the global enviroment

As for external costs (“negative externalities”), Quiggin notes that the leading British economist Lord Nicholas Stern has described climate change as “the biggest market failure in history”. So now you know why so many of the nation’s economists are appalled by Morrison’s dereliction.
