To my parents
The idea of writing an introduction to economics that is accessible to the broadest possible audience was first raised by Penguin through my then editor, Will Goodlad, in the autumn of 2011. Will has since then moved on to other things, but he provided helpful inputs into the shaping and the writing of the book, even while he was going through an intense phase of establishing a new venture.
The book could not have been written without Laura Stickney, my editor. It must have been difficult for her, as she had to put up with periods of silence and numerous rewrites of the earlier chapters. However, she put her faith in me and saw me through the process, with only the gentlest prodding and with an enormous amount of excellent advice, both substantive and editorial. I cannot thank her more.
Ivan Mulcahy, my literary agent, as usual, provided very important input. In particular, his suggestions on some of an earlier incomplete draft breathed life back into the book, when the writing process was in danger of losing its momentum, and I was in danger of losing my faith in the book myself.
Peter Ginna, my US editor, also gave me a lot of important input, especially in the final phase of the book.
Numerous friends provided me with help and encouragement, but three individuals deserve a special mention. Duncan Green, William Milberg and Deepak Nayyar read all the chapters (some of them in more than one version) and gave me extremely helpful comments. They also gave me moral support through difficult phases of the project, of which there were many.
Felix Martin provided very important inputs into the shaping of the book from the stage when it was a mere plan. He also read several chapters of the book and given me very helpful comments. Milford Bateman read almost all the chapters of the book and offered very useful comments. Finlay Green also read most of the chapters and suggested many ways in which I could improve the accessibility of my writing.
I would also like to thank many people who read various versions of the book plan or chapters of the book and gave me useful comments. They are, in alphabetical order, Jonathan Aldred, Antonio Andreoni, John Ashton, Roger Backhouse, Stephanie Blankenberg, Aditya Chakrabortty, Hasok Chang, Victoria Chick, Michele Clara, Gary Dymski, Ilene Grabel, Geoffrey Hodgson, Adriana Kocornik-Mina, David Kucera, Costas Lapavitsas, Sangheon Lee, Carlos Lopez-Gomez, Tiago Mata, Gay Meeks, Seumas Milne, Dimitris Milonakis, Brett Scott, Jeff Sommers, Daniel Tudor, Bhaskar Vira and Yuan Yang.
My PhD student and research assistant, Ming Leong Kuan, provided me with extremely efficient and creative help in securing and processing the necessary data for the book. Given the importance that I am attaching to ‘real-life numbers’ in this book, Ming Leong’s assistance was essential in making the book what it is.
During the two years in which I was writing the book, Hee-Jeong, my wife, Yuna, my daughter, and Jin-Gyu, my son, suffered a lot but gave me a huge amount of love and support. Hee-Jeong and Yuna also read many of the chapters and gave me a lot of very helpful comments. Jin-Gyu kept reminding me that there are more important things in life than economics, such as Dr Who, Hercule Poirot and Harry Potter.
My little family in England would not have had the solidity it has without the love of our extended family back in Korea. My parents-in-law have showered us with a lot of loving support. My own parents have been a continuous source of love and encouragement for us. Above all, I would not be what I am today without their sacrifice and nurturing. I dedicate the book to them.
Since you have picked up this book, you probably have at least a passing interest in economics. Even so, you may be reading this with some trepidation. Economics is supposed to be difficult – perhaps not physics-difficult but demanding enough. Some of you may remember hearing an economist on the radio making an argument that sounded questionable but accepting it because, after all, he is the expert, and you haven’t even read a proper book on economics.
But is economics really that difficult? It doesn’t need to be – if it is explained in plain terms. In my previous book, 23 Things They Don’t Tell You about Capitalism, I even stuck my neck out and said that 95 per cent of economics is common sense – made to look difficult, with the use of jargons and mathematics.
Economics is not alone in appearing to be more difficult to outsiders than it really is. In any profession that involves some technical competence – be it economics, plumbing or medicine – jargons that facilitate communication within the profession make its communication with outsiders more difficult. A little more cynically, all technical professions have an incentive to make themselves look more complicated than they really are so that they can justify the high fees their members charge for their services.
Even considering all this, economics has been uniquely successful in making the general public reluctant to engage with its territory. People express strong opinions on all sorts of things despite not having the appropriate expertise: climate change, gay marriage, the Iraq War, nuclear power stations. But when it comes to economic issues, many people are not even interested, not to speak of not having a strong opinion about them. When was the last time you had a debate on the future of the Euro, inequality in China or the future of the American manufacturing industry? These issues can have a huge impact on your life, wherever you live, by affecting, positively or negatively, your job prospects, your wage and eventually your pension, but you probably haven’t thought about them seriously.
This curious state of affairs is only partly explained by the fact that economic issues lack the visceral appeals that things like love, dislocation, death and war have. It exists mainly because, especially in the last few decades, people have been led to believe that, like physics or chemistry, economics is a ‘science’, in which there is only one correct answer to everything; thus non-experts should simply accept the ‘professional consensus’ and stop thinking about it. Gregory Mankiw, the Harvard economics professor and the author of one of the most popular economics textbooks, says: ‘Economists like to strike the pose of a scientist. I know, because I often do it myself. When I teach undergraduates, I very consciously describe the field of economics as a science, so no student would start the course thinking he was embarking on some squishy academic endeavor.’1
As it will become clearer throughout the book, however, economics can never be a science in the sense that physics or chemistry is. There are many different types of economic theory, each emphasizing different aspects of complex reality, making different moral and political value judgements and drawing different conclusions. Moreover, economic theories constantly fail to predict real-world developments even in areas on which they focus, not least because human beings have their own free will, unlike chemical molecules or physical objects.2
If there is no one right answer in economics, then we cannot leave it to the experts alone. This means that every responsible citizen needs to learn some economics. By this I don’t mean picking up a thick textbook and absorbing one particular economic point of view. What is needed is to learn economics in such a way that one becomes aware of different types of economic arguments and develops the critical faculty to judge which argument makes most sense in a given economic circumstance and in light of which moral values and political goals (note that I am not saying ‘which argument is correct’). This requires a book that discusses economics in a way that has not been tried, which I believe this book does.
How is this book different from other introductory books to economics?
One difference is that I take my readers seriously. And I mean it. This book will not be a digested version of some complicated eternal truth. I introduce my readers to many different ways of analysing the economy in the belief that they are perfectly capable of judging between different approaches. I do not eschew discussing the most fundamental methodological issues in economics, such as whether it can be a science or what role moral values do (and should) play in economics. Whenever possible, I try to reveal the assumptions underlying different economic theories so that readers can make their own judgements about their realism and plausibility. I also tell my readers how numbers in economics are defined and put together, urging them not to take them as something as objective as, say, the weight of an elephant or the temperature of a pot of water.* In short, I try to explain to my reader how to think, rather than what to think.
Engaging the reader at the deepest level of analysis, however, does not mean that the book is going to be difficult. There is nothing in this book that the reader cannot understand, as far as he or she has had a secondary education. All I ask of my readers is the curiosity to find out what is really going on and the patience to read through a few paragraphs at the same time.
Another critical difference with other economics books is that my book contains a lot of information on the real world. And when I say ‘world’, I mean it. This book provides information on many different countries. This is not to say that all countries get equal attention. But, unlike most other books in economics, the information will not be confined to one or two countries or to one type of country (say, rich countries or poor countries). Much of the information provided will be numbers: how large the world economy is, how much of it is produced by the US or Brazil, what proportions of their outputs China or the Democratic Republic of Congo invest, how long people work in Greece or Germany. But this will be complemented by qualitative information on institutional arrangements, historical backgrounds, typical policy and the like. The hope is that at the end of this book the reader can say that he or she has some feel about the way in which the economy actually works in the real world.
‘And now for something completely different …’*
I realize that not all readers are ready to spend a lot of time on this book, at least to begin with. Therefore, I suggest several different ways of reading this book, depending on how much time you think you can afford.
If you have ten minutes: Read the chapter titles and the first page of each chapter. If I am lucky, at the end of those ten minutes, you may suddenly find that you have a couple of hours to spare.
If you have a couple of hours: Read Chapters 1 and 2 and then the Epilogue. Flick through the rest.
If you have half a day: Read only the headlines – section titles and the summaries in italics that occur every few paragraphs. If you are a fast reader, you may also cram in the introductory section and the concluding remarks in each chapter.
If you have the time and the patience to read through: Please do. That will be the most effective way. And you will make me very happy. But even then you can skip bits that don’t interest you much and read only the headlines in those bits.
What is economics?
A reader who is not familiar with the subject might reckon that it is the study of the economy. After all, chemistry is the study of chemicals, biology is the study of living things, and sociology is the study of society, so economics must be the study of the economy.
But according to some of the most popular economics books of our time, economics is much more than that. According to them, economics is about the Ultimate Question – of ‘Life, the Universe and Everything’ – as in The Hitchhiker’s Guide to the Galaxy, the cult comedy science fiction by Douglas Adams, which was made into a movie in 2005, with Martin ‘The Hobbit’ Freeman in the leading role.
According to Tim Harford, the Financial Times journalist and the author of the successful book The Undercover Economist, economics is about Life – he has named his second book The Logic of Life.
No economist has yet claimed that economics can explain the Universe. The Universe remains, for now, the turf of physicists, whom most economists have for centuries been looking up to as their role models, in their desire to make their subject a true science.* But some economists have come close – they have claimed that economics is about ‘the world’. For example, the subtitle of the second volume in Robert Frank’s popular Economic Naturalist series is How Economics Helps You Make Sense of Your World.
Then there is the Everything bit. The subtitle of Logic of Life is Uncovering the New Economics of Everything. According to its subtitle, Freakonomics by Steven Levitt and Stephen Dubner – probably the best-known economics book of our time – is an exploration of the Hidden Side of Everything. Robert Frank agrees, even though he is far more modest in his claim. In the subtitle of his first Economic Naturalist book, he only said Why Economics Explains Almost Everything (emphasis added).
So, there we go. Economics is (almost) about Life, the Universe and Everything.†
When you think about it, this is some claim coming from a subject that has spectacularly failed in what most non-economists think is its main job – that is, explaining the economy.
In the run-up to the 2008 financial crisis, the majority of the economics profession was preaching to the world that markets are rarely wrong and that modern economics has found ways to iron out those few wrinkles that markets may have; Robert Lucas, the 1995 winner of the Nobel Prize in Economics,* had declared in 2003 that the ‘problem of depression prevention has been solved’.1 So most economists were caught completely by surprise by the 2008 global financial crisis.† Not only that, they have not been able to come up with decent solutions to the ongoing aftermaths of that crisis.
Given all this, economics seems to suffer from a serious case of megalomania – how can a subject that cannot even manage to explain its own area very well claim to explain (almost) everything?
You may think I am being unfair. Aren’t all these books aimed at the mass market, where competition for readership is fierce, and therefore publishers and authors are tempted to hype things up? Surely, you would think, serious academic discourses would not make such a grand claim that the subject is about ‘everything’.
These titles are hyped up. But the point is that they are hyped up in a particular way. The hypes could have been something along the line of ‘how economics explains everything about the economy’, but they are instead along the lines of ‘how economics can explain not just the economy but everything else as well’.
The hypes are of this particular variety because of the way in which the currently dominant school of economics, that is, the so-called Neoclassical school, defines economics. The standard Neoclassical definition of economics, the variants of which are still used, is given in the 1932 book by Lionel Robbins, An Essay on the Nature and Significance of Economic Science. In the book, Robbins defined economics as ‘the science which studies human behaviour as a relationship between ends and scarce means which have alternative uses’.
In this view, economics is defined by its theoretical approach, rather than its subject matter. Economics is a study of rational choice, that is, choice made on the basis of deliberate, systematic calculation of the maximum extent to which the ends can be met by using the inevitably scarce means. The subject matter of the calculation can be anything – marriage, having children, crime or drug addiction, as Gary Becker, the famous Chicago economist and the winner of 1992 Nobel Prize in Economics, has written about – and not just ‘economic’ issues, as non-economists would define them, such as jobs, money or international trade. When Becker titled his 1976 book The Economic Approach to Human Behaviour, he was really declaring without the hype that economics is about everything.
This trend of applying the so-called economic approach to everything, called by its critics ‘economics imperialism’, has reached its apex recently in books like Freakonomics. Little of Freakonomics is actually about economic issues as most people would define them. It talks about Japanese sumo wrestlers, American schoolteachers, Chicago drug gangs, participants in the TV quiz show The Weakest Link, real estate agents and the Ku Klux Klan.
Most people would think (and the authors also admit) that none of these people, except real estate agents and drug gangs, have anything to do with economics. But, from the point of view of most economists today, how Japanese sumo wrestlers collude to help each other out or how American schoolteachers fabricate their pupils’ marks to get better job assessments are as legitimate subjects of economics as whether Greece should stay in the Eurozone, how Samsung and Apple fight it out in the smartphone market or how we can reduce youth unemployment in Spain (which is over 55 per cent at the time of writing). To those economists, those ‘economic’ issues do not have privileged status in economics, they are just some of many things (oh, I forgot, some of everything) that economics can explain, because they define their subject in terms of its theoretical approach, rather than its subject matter.
An obvious alternative definition of economics, which I have been implying, is that it is the study of the economy. But what is the economy?
The most intuitive answer to most readers may be that the economy is anything to do with money – not having it, earning it, spending it, running out of it, saving it, borrowing it and repaying it. This is not quite right, but it is a good starting point for thinking about the economy – and economics.
Now, when we talk of the economy being about money, we are not really talking about physical money. Physical money – be it a banknote, a gold coin or the huge, virtually immovable stones that were used as money in some Pacific islands – is only a symbol. Money is a symbol of what others in your society owe you, or your claim on particular amounts of the society’s resources.2
How money and other financial claims – such as company shares, derivatives and many complex financial products, which I will explain in later chapters – are created, sold and bought is one huge area of economics, called financial economics. These days, given the dominance of the financial industry in many countries, a lot of people equate economics with financial economics, but it is actually only a small part of economics.
Your money – or the claims you have over resources – may be generated in a number of different ways. And a lot of economics is (or should be) about those.
The most common way to get money – unless you have been born into it – is to have a job (including being your own boss) and earn money from it. So, a lot of economics is about jobs. We can reflect on jobs from different perspectives.
Jobs can be understood from the point of view of the individual worker. Whether you get a job and how much you are paid for it depends on the skills you have and how many demands there are for them. You may get very high wages because you have very rare skills, like Cristiano Ronaldo, the football player. You may lose your job (or become unemployed) because someone invents a machine that can do what you do 100 times faster – as happened to Mr Bucket, Charlie’s father, a toothpaste cap-screwer, in the 2005 movie version of Roald Dahl’s Charlie and the Chocolate Factory.* Or you have to accept lower wages or worse working conditions because your company is losing money thanks to cheaper imports from, say, China. And so on. So, in order to understand jobs even at the individual level, we need to know about skills, technological innovation and international trade.
Wages and working conditions are also deeply affected by ‘political’ decisions to change the very scope and the characteristics of the labour market (I have put ‘political’ in quotation marks, as in the end the boundary between economics and politics is blurry, but that is a topic for later – see Chapter 11). The accession of the Eastern European countries to the European Union has had huge impacts on the wages and behaviours of Western European workers, by suddenly expanding the supply of workers in their labour markets. The restriction on child labour in the late nineteenth century and early twentieth centuries had the opposite effect of shrinking the boundary of the labour market – suddenly a large proportion of the potential employees were shut out of the labour market. Regulations on working hours, working conditions and minimum wages are examples of less dramatic ‘political’ decisions that affect our jobs.
In addition to holding down a job, you can get money through transfers – that is, by simply being given it. This can be either in the form of cash or ‘in kind’, that is, direct provision of particular goods (e.g., food) or services (e.g., primary education). Whether in cash or in kind, these transfers can be made in a number of different ways.
There are transfers made by ‘people you know’. Examples include parental support for children, people taking care of elderly family members, gifts from local community members, say, for your daughter’s wedding.
Then there is charitable giving, that is, transfer voluntarily made to strangers. People – sometimes individually sometimes collectively (e.g., through corporations or voluntary associations) – give to charities that help others.
In terms of its quantity, charitable giving is overshadowed in many multiples by transfers made through governments, which tax some people to subsidize others. So a lot of economics is naturally about these things – or the areas of economics known as public economics.
Even in very poor countries, there are some government schemes to give cash or goods in kind (e.g., free grains) to those who are in the worst positions (e.g., the aged, the disabled, the starving). But the richer societies, especially those in Europe, have transfer schemes that are much more comprehensive in scope and generous in amounts. This is known as the welfare state and is based on progressive taxation (those who earn more paying proportionally larger shares of their incomes in taxes) and universal benefits (where everyone, not just the poorest or the disabled, is entitled to a minimum income and to basic services, such as health care and education).
Once you gain access to resources, whether through jobs or transfers, you consume them. As physical beings, we need to consume some minimum amount of food, clothes, energy, housing, and other goods to fulfil our basic needs. And then we consume other goods for ‘higher’ mental wants – books, musical instruments, exercise equipment, TV, computers and so on. We also buy and consume services – a bus ride, a haircut, a dinner at a restaurant or even a holiday abroad.3
So a lot of economics is devoted to the study of consumption – how people allocate money between different types of goods and services, how they make choices between competing varieties of the same product, how they are manipulated and/or informed by advertisements, how companies spend money to build their ‘brand images’ and so on.
In order to be consumed, these goods and services have to be produced in the first place – goods in farms and factories and services in offices and shops. This is the realm of production – an area of economics that has been rather neglected since the Neoclassical school, which puts emphasis on exchange and consumption, became dominant in the 1960s.
In standard economics textbooks, production appears as a ‘black box’, in which somehow quantities of labour (work by humans) and capital (machines and tools) are combined to produce the goods and services. There is little recognition that production is a lot more than combining some abstract quanta called labour and capital and involves getting many ‘nitty-gritty’ things right. And these are things that most readers may not normally have associated with economics, despite their crucial importance for the economy: how the factory is physically organized, how to control the workers or deal with trade unions, how to systematically improve the technologies used through research.
Most economists are very happy to leave the study of these things to ‘other people’ – engineers and business managers. But, when you think about it, production is the ultimate foundation of any economy. Indeed, the changes in the sphere of production usually have been the most powerful sources of social change. Our modern world has been made by the series of changes in technologies and institutions relating to the sphere of production that have been made since the Industrial Revolution. The economics profession, and the rest of us whose views of the economy are informed by it, need to pay far more attention to production than currently.
My belief is that economics should be defined not in terms of its methodology, or theoretical approach, but in terms of its subject matter, as is the case with all other disciplines. The subject matter of economics should be the economy – which involves money, work, technology, international trade, taxes and other things that have to do with the ways in which we produce goods and services, distribute the incomes generated in the process and consume the things thus produced – rather than ‘Life, the Universe and Everything’ (or ‘almost everything’), as many economists think.
Defining economics in this way makes this book unlike most other economics books in one fundamental way.
As they define economics in terms of its methodology, most economics books assume that there is only one right way of ‘doing economics’ – that is, the Neoclassical approach. The worst examples won’t even tell you that there are other schools of economics than the Neoclassical one.
By defining economics in terms of the subject matter, this book highlights the fact that there are many different ways of doing economics, each with its emphases, blind spots, strengths and weaknesses. After all, what we want from economics is the best possible explanation of various economic phenomena rather than a constant ‘proof’ that a particular economic theory can explain not just the economy but everything.
