Book Review: Economics, A Very Short Introduction

I came across this book, as I mentioned, by regularly reading Brad DeLong’s blog (which is very rewarding in and of itself). He has mentioned this book frequently and always admiringly on his blog, and with good reason. It is one of the very best introductory books you could ever hope to read.

But, and this is an important but, it is not the most accessible book you will read about economics. Even after multiple readings, I find the going slow, and not just because of the technical concepts in the book but because of how much thought and (if you’ll forgive a particularly poor way to phrase this) thought-provoking thought is packed into only one hundred and fifty odd pages.

In fact, in the post in which I alluded to this book for the first time, I mentioned that the entire book should not be read at one seating, or at one go. Brad DeLong, based on his blogs, would probably criticize me for saying so, but I stand by that recommendation. The prologue is magnificent reading, and the rest of the book even more so – but the prologue is a nice meandering walk up a gentle hill. The rest of the book is a trek in the upper reaches of the Himalayas. To be clear, that is a good thing! You should trek up the upper reaches of the Himalayas, but a little training might be in order first.

The rest of this post is in praise of the prologue, which, as I have mentioned is worth many times the price of admission. Partha Dasgupta talks about Becky and Desta, two little girls who are of the same age (more or less) but are separated by a) geography and b) economic circumstances.

The author describes the lives of the two little girls and how very different they are: what they do during a day, what their parents’ lives are like, where they live, how they are being educated, and ultimately, what kind of lives they are likely to lead in the future. And then, Partha Dasgupta asks two very simple, but urgent questions.

Why? Why are their lives so different? Is it because of the geography they find themselves in? Is it because of historical factors? Might past and present governments have a role to play in how different their lives are? Might the choices made by their parents be a factor?All of these at the same time, perhaps? Who can say?

Second: given that their circumstances are different, can we do anything to make sure that Desta gets a leg up in life? How can her circumstances be made better, while leaving Becky’s either the same or better (but certainly not worse)? In other words, what needs to change in terms of markets, policies, institutions and indeed beliefs, for meaningful, long-lasting and sustainable change to visit Desta’s life?

I shall be deliberately provocative: if pondering these questions does not excite you about learning more about economics, then nothing ever will. Strong words, but I stand by them.

Read the whole book (eventually), but read the prologue right now.

What five books might you want to read today to help you understand India better today? I replied to a request by a friend on Twitter recently about a somewhat similar topic

and while there will be some overlap with the list on that thread, here are my (very idiosyncratic) picks about understanding India better.

Please note:

This list is not exhaustive. I sincerely hope it changes next year; I would be sorely disappointed in myself and the world if it didn’t. It’s my way of looking at India – yours will and should be different (that’s what makes the world awesome). I recommending you read a book does NOT mean I agree with it, endorse it or agree with it’s world view. It does imply that your understanding of India will be richer for having read it, in my opinion.

All that being said, here’s my list of five books that will help you understand India better. Happy Independence Day!

  1. How the BJP Wins, by Prashant Jha
  2. India After Gandhi, by Ramchandra Guha
  3. English August, by Upamanyu Chatterjee
  4. Behind the Beautiful Forevers, by Katherine Boo
  5. India’s Long Road, by Vijay Joshi


Book Review: The Undercover Economist

I fondly remember this book because of how spooky the introduction section was to me. Tim Harford begins the book by thanking the reader for buying the book, but then goes on to say that if the reader is anything like him, they’re probably sampling the book in a bookstore while sipping a coffee, judging whether to buy it or not. As it turns out, that is exactly what I was doing.

But the book (which I did buy later) was appealing to me for much more than that. I have written extensively elsewhere about how I hate textbooks. One reason I despise them so is because they introduce concepts in economics first: verbally, diagrammatically and worst of all, mathematically, and only then provide an application of the concept in a dry, mealy-mouthed little “box”. It’s like a chef teaching you how to cook by spending a week telling you how to hold a knife and then, almost as an after-thought saying “Oh, here’s a tomato.”

But right from the first chapter onward, Harford dives right into the real world, shows us a problem we can all identify with, and then asks: how might thinking like an economist help you understand this problem better? That’s the whole point of learning economics! It’s the tool that should be in the “box”, and the world outside of it.

In any case, the book is great because of a secondary reason as well: Harford understands, emphasizes and makes relatable the concept of domain independence. Domain independence essentially say that understanding an idea in one domain shouldn’t preclude you from applying that idea in other domains (I read about this particular phrasing of the idea in Anti-fragile, another book I’d heavily recommend). So while the book is about coffee bars, supermarkets, stock markets and so on, you really should keep in mind the fact that these concepts are applicable in many other areas.

My favorite chapter is the last one, which is on China. Harford explains (some might say far too succinctly) how modern China came to be, but keep in mind that this is meant to be an introductory book. Will people learning economics for the first time, especially Indians, wonder how China is the way it is and why India isn’t? Of course they will: and this chapter is a good first pass at tackling this problem.

Which is not to say that the other chapters are not worth your time, of course – each of them are worth a read, and the book’s purpose is served if it whets your appetite. This is not meant to satiate your curiosity about economics – the exact opposite, in fact. It is meant to make you want to read much, much more – while at the same time making all of what you read much more relatable.

Tim Harford has written many other books, and he used to write a magnificent agony aunt column devoted to economics, and also runs some interesting podcasts – about all of which much more in later posts. But for the moment, suffice it to say  that you’d hardly go wrong if you read this book for starters.

5 Great Books to Start Learning Economics

It’s a question faced by anybody who’s ever taught introductory courses in economics, and it’s a question that faces anybody who has tried to start learning economics – and it’s high time I tried answering it.

What follows is a very brief description of five books that I think fit the bill: each of these are books that serve as a very good introduction to the subject.

None of them, it should be said, are stand-alone (almost no book ever is). You will need to read many more books to get a feel for the subject. But these are very useful gateway drugs.

This post will simply introduce each book in a paragraph, no more. The title of the book will be linked to the relevant Amazon India page (not affiliate links). Over the next five days, I’ll add a separate blog post about each of these books, and finish the series with books that almost made the cut.

  1. The Undercover Economist: This is a book written by Tim Harford, and is my preferred response when I’m asked “Have you read Freakonomics?” (Yes, but have you read “The Undercover Economist”?). The book is written the way I think great textbooks about economics ought to be written: they begin with real life conundrums and use economic tools to probe at these conundrums, rather than begin with a dry diagram or set of equations, and put the real world application in a “box”. He deal with questions ranging from why coffee costs so much at airports, and ponders the question of how China grew so rich as well. Written in an easy, accessible style, it is a great introductory book to the subject.
  2. Economics, A Very Short Introduction: I came across this book via a blog post written by Brad DeLong, in which he mentioned that he uses an excerpt from this book as a way to get people interested in thinking about economics. I couldn’t agree more: this is probably the best, thoughtful way to start thinking about “big picture” economics. But there’s one caveat: if you are just starting to learn economics, do not bother reading beyond the prologue, which is the first fifteen pages or so. Then spend a good six months or so reading other stuff about economics, and then come back and tackle the rest of the book. But Becky and Desta will be my friends forever – unforgettable characters.
  3. The Little Book of Economics: Greg Ip is the only person I know of whose pocket money, when he was a child, was linked to inflation. This made him a very keen student of economic theory (you might almost say he was incentivised to study economics), and that is probably a causal factor in he writing this book. Again, as with Harford’s book, Ip begins with stuff we can all observe around us, and asks “Why is this so?” – and then uses tools from the economist’s toolkit to tackle these problems. The focus is rather more on so-called “macroeconomics”, but that doesn’t make the book any less interesting. (By the way, if you’re now tempted to ask which of these I should read, the answer is “all”.)
  4. Discover Your Inner Economist: Tyler Cowen is the world’s most prolific blogger by some magnitude, and he also makes the time to write some extremely thought-provoking books, and this is one of them. How much should you pay/tip your dentist (if at all)? Should you pay your daughter to help with the household chores (short answer: no)? Should I finish every book I buy (short answer:no)? These, and other such questions are dealt with in the book in a Cowenish, non-whimsical way that still ends up being entertaining and enlightening.
  5. Day to Day Economics: This book is perhaps more applicable to Indian students than to those from other parts of the world, but Satish Deodhar writes a very accessible book about the Indian economy and it’s workings. It is the closes to being a conventional textbook out of the five I have recommended here, but I mean that in a good way. You will understand much more about the Indian economy specifically for having read this book, and it is well worth  your time if you are beginning your journey as an economics student.
