According to John Maynard Keynes "The master economist ... must be mathematician, historian, statesman, philosopher-in some degree. He must understand symbols and speak in words. He must contemplate the particular in terms of the general, and touch abstract and concrete in the same flight of thought. He must study the present in the light of the past for the purposes of the future. No part of man's nature or his institutions must lie entirely outside his regard. He must be purposeful and disinterested in a simultaneous mood; as aloof and incorruptible as an artist, yet sometimes as near the earth as a politician."
So even a very bright fifteen year old is not going to be able to understand macroeconomics - it will need half a lifetime of professional training and experience to get him to a point where he can grasp even the basics. Unless, that is, he has Tim Harford as his guide. Using the Q&A Socratic debate format Tim leads the reader towards an understanding of why macroeconomics is so hard, why no solutions have yet been found and maps out potential sources of hope for future solutions. Along the way we encounter some of the latest thinking on behavioural economics, on why economics growth can continue forever, on why happiness economics is just plain weird and on how the Euro is like Dr Strangelove's doomsday device with Greece playing the role of Major Kong.
Although this book could be read on its own I feel it is better to read The Undercover Economist
first so that the reader has a basic understanding of microeconomic concepts before embarking on "The UE-SB". The takeaway from this book is different from his earlier works. Reading it has persuaded me that we need a long term inflation rate of more than 2% to get us out of this depression but I believe that the 4% rate that Tim suggests is too high. Let's see what Mark Carney does over 2014.
