BOOK REVIEW ‘THE WHY AXIS’ BY URI GNEEZY & JOHN LIST

Introduction
Another book that explores ‘the hidden side of everything’. Unlike the Dubner and Levitt books the topics explored here are quite narrow although not less interesting. Rather than separate chapters on different subjects this book looks at some very specific issues and the evidence connecting them.  The main focus of the book the ‘new field’ of economic experiments, controlling for factors and seeing how groups react to different incentives with the aim being to solve problems such as underachievement in schools and discrimination.
Style
Nothing too technical here to put off a casual reader, this is another of many books trying to increase awareness of microeconomics and therefore it has to be accessible to everyone. One thing that did annoy me was that some parts start a story but you can’t find out what happens until it is used to illustrate the conclusion. Although you can’t really  fault a literary device being used in a book.
Content
The main topics explored relate to discrimination and the achievement gap between students. Exploration happens through looking at field experiments, most of which were engineered by the authors or their colleagues during their careers. Other topics that the authors have looked into include how to get people to donate to charity, experiment to get ahead in business and a number of interesting by products besides this. Some topics span multiple chapters which other topics are only a few pages long.
Conclusions
‘The Why Axis’ covers a few subjects in a great deal of detail and although all of these topics are interesting the ties between them are vague. ‘The Why Axis’ was a very interesting read and I learnt a lot from it that I hope I’ll have power to put into practice some of the suggestions to combat discrimination and inequality. The only criticism I have is that the topics don’t really ‘flow’ together all that well, it can’t be helped as there’s not enough material for a singular book on a singular topic so it has to be a mash-up of previous work in a nicely digestible holiday novel.
Usefulness
In terms of classes I don’t think this is a very useful book. Yes it was interesting and yes I enjoyed reading it but I don’t think I would ever be able to reference this book in an essay. Still, if you enjoyed ‘Freakonomics’ you’ll enjoy this one too!

BOOK REVIEW ‘THE UNDERCOVER ECONOMIST’ BY TIM HARFORD

Introduction
I found this book in the library when I was supposed to be studying. Good call because this was actually a great revision book for MICROECONOMIC POLICY! Look at the contents page…. It’s practically the syllabus… The chapters are not sequential so you can pick and choose what you read about and the topics are all have ‘everyday applications’ as the whole idea of the book is to look at the world around you with ‘the eyes of an economist’ so each theoretical concept is introduced with real world evidence.
Style
Tim Harford is a great author because he’s so easy to read. Sometimes a book will say ‘no previous knowledge of economics necessary’ but they’re flat our lying. That’s not the case with Harford as he builds up your knowledge from the beginning and then adds to it with every chapter.
Content
I’m not saying that you can ace Micro Policy with this book but the basic concepts are explained in a way that make it easy to build on with the lecture notes. Here are most of the topics that Harford explores and explains:
  • Ricardo’s theory of rent & scarcity power
  • The value of the marginal
  • The effects of rent control
  • The effects of immigration
  • Price discrimination (including location pricing)
  • How perfect markets work and why we use them (1)
  • Efficiency vs fairness in taxation
  • Market & Government failure
  • Dealing with externalities
  • Asymmetric information/incomplete contracts/moral hazard
  • Efficient market hypothesis
  • Game theory and auctions
  • Competitive and absolute advantage
  • Rent seeking
Also topics such as the rise of china, the recent financial crisis and environmental issues are also discussed
Conclusions
‘The Undercover Economist’ is well written and covers a lot of material in a non-convolute way. Topics of recent interest are discussed thoroughly using concepts that Harford introduces through storybook examples and anecdotes.
Usefulness
If you are taking Microeconomic Policy you should read this book. It’s like revision but easier. I thought I understood the topics presented in lecture but Harford is able to go through the concepts with more leisure so that the examples he used still stick in my mind even a year after I first read them.
Notes
(1) I re-read this chapter a lot because it explains why economists continue to use models of perfect markets when they’re so inapplicable to the real world

HOW MANY PEOPLE HAD SEX TODAY?


The other day we had a society meeting. That was over pretty quickly because we’re a very organised bunch but eventually we got around to a different topic:
How many people in the UK were having sex at 18:03 Sunday 29th September?
(Please keep in mind that this is based on HEAVILY estimated data! You’re quite welcome to point out where our estimates were wrong but they were just estimates based on our collective knowledge.)
  • The population of the UK is 62 million. Let’s say 60 million for the sake of maths
  • Discount 50% of the population (>65 years/
  • Account for the fact that it’s 18:00 on a Sunday = the only people likely to be having sex are those in relationships
  • On average people in established relationships have sex three times a week so they have a 3/7 chance of having sex today
  • 3/7 of 30 million = 3.4 million
  • 24 hours in a day – 7 hours for sleep = 17 hours to potentially have sex
  • 3.4 million / 17 hours = 100, 000 people having sex each hour
So. After that we saw that someone had already asked this question. The answer is that on any random day on a random hour sex happens an average 5.5 million times in a population of 6.7 billion (we’ve done enough maths for today… We’ll pretend that’s the current population….) We already set the population of the UK at 62 million which means if we round the numbers it means we were right! In the UK 100,000 people are having sex each hour!
So yeah, considering how much leeway we took with the numbers, we got pretty close!

BOOK REVIEW ‘END THIS DEPRESSION NOW!’ BY PAUL KRUGMAN


Introduction
I used to really love Paul Krugman because he explains things in such an easy way. Recently people have been telling me Krugman isn't the most reliable economist around so I decided to re-read this book in particular which I thought was the best book ever written for a time because it’s so straightforward.
Style
The book is dedicated: ‘To the unemployed, who deserve better’ which tells you a lot about Krugman’s writing style. The book assumes an intelligent reader with no previous knowledge of economics so lots of important concepts that are thrown around during lectures are explained remarkably well. However only rarely does Krugman tell us what the concept is called ‘in the jargon’ so it’s not something that’s suitable to read the night before the Macro Theory exam.
Content
The first chapter explains the effects of unemployment and lost economic growth the result has been anger and despair that rivals that of the great depression. Krugman then speaks about how the depression led to the rise of Hitler in inter-war Germany (1).I know there’s a word for the fallacy of taking an argument and drawing it to a silly, worst case scenario conclusion but I don’t remember what it’s called. Maybe that fallacy applies here or maybe Krugman is just being rational when he warns that a depression brings out the worst in people.
This introduces Krugman’s central message: economists have learnt from the great depression and know what has to be done to fix it but the fix is difficult politically. The government needs to raise spending to boost demand (2)  and this has to be done through fiscal policy as during a liquidity trap monetary policy becomes useless.(3)
The large part of the book is then taken up with the run-up to the current crisis, some common fallacies spread by political phrasing and generally refuting any arguments that could be levied against the conclusions drawn. I enjoyed this build up as Krugman is quick to draw comparisons and make snide remarks during what would otherwise be a dry section which makes the chapters easy to read.(4) For example, I am now informed that there is no ‘structural problem’ in unemployment or whatever other excuses politicians make up; they simply just don’t want to fork out the amount of money that would be necessary to end this recession.
We are reminded of the Obama stimulus bill, known as the ‘American Recovery and Reinvestment Act’ totalling $787billion. Krugman says fiscal stimulus of this size was ‘too small for the job’ and ended up discrediting the whole idea of fiscal stimulus. Reasons why opponents criticize fiscal policy are discussed and dismissed, including fears of debt and inflation.
Finally, a chapter is spent analysing the problems in Europe along with the dangers of austerity. Krugman ends the book with a five point plan to end the crisis and a summary of what has been discussed. The very last paragraph contains a call to put more pressure of the government to respond to the current economic situation before it’s too late.
Conclusions
Mr. Sean Rickard once said during a lecture that most economics books for the general public could probably be condensed into a slightly-too-long chapter and forget the extra 200 or so pages that come after. But without 200+ pages you can’t sell the book for £15. I think this might be one of those book.
The book is enjoyable to read due to the sarcastic way arguments are deflected but a lot of the information could be condensed without the irrelevant stories and comparisons. The conclusions of the book make sense after the detailed reasoning Krugman employs but I’m not sure whether his evidence supported his conclusions or whether they just refuted all other options.
Usefulness
Although not particularly relevant to a particular course, the chapters covering the current financial crisis are detailed and well explained. Background is also given on the great depression so that comparisons between the 1930s and 2008 can be made so there’s lots of economic history that students should really be aware of explained.
The book assumes an American reader so the reader will need to understand the barebones of the Federal Reserve System and a rudimentary knowledge of macroeconomics is useful if you want the knowledge to really stick in your head. If you have time to kill between macro theory and macro policy this book would be useful in creating a bridge between the two courses.
Notes

(1) This is immediately followed by a mention of Godwin’s law which should have prompted that part of the chapter being summarily deleted but nevermind…
(2) Can I just say I am sick of this ‘Great Capitol Hill Baby Sitting Co-Op Crisis‘ story? I don’t care how well it illustrates a point can we please find a different example of quantitative easing already?
(3) Which Tim Congdon disagrees with in ‘Money in a Free Society‘ which kick started my whole ‘Someone disagrees with Krugman?!’ disillusioning process in which I learnt that many economists can seemingly be right at the same time while still disagreeing with each other.
(4) I particularly like the idea of a ‘garden- variety recession’ that is quickly turned around with quantitative easing. I mostly like this because other sources agree with this view and it’s less confusing for the poor undergraduate students when economists agree with each other.
