“Economics should be defined in terms of what it is about. It should be about how people produce things, how people exchange them, how people earn income, how they pay taxes, how the government provides infrastructure with tax revenue, and how it conducts monetary policy. The subject has to be defined in terms of the object of inquiry.”

“As these contrasts show, capitalism has undergone enormous changes in the last two and a half centuries. While some of Smith’s basic principles remain valid, they do so only at very general levels.For example, competition among profit-seeking firms may still be the key driving force of capitalism, as in Smith’s scheme. But it is not between small, anonymous firms which, accepting consumer tastes, fight it out by increasing the efficiency in the use of given technology. Today, competition is among huge multinational companies, with the ability not only to influence prices but to redefine technologies in a short span of time (think about the battle between Apple and Samsung) and to manipulate consumer tastes through brand-image building and advertising.”

“A lot of things that we cannot buy and sell in markets used to be totally legal objects of market exchange - human beings when we had slavery, child labour, human organs, and so on. So there is no economic theory that actually says that you shouldn't have slavery or child labour because all these are political, ethical judgments.”

“By liberating women from household work and helping to abolish professions such as domestic service, the washing machine and other household goods completely revolutionised the structure of society.”

“Economics should be defined in terms of what it is about. It should be about how people produce things, how people exchange them, how people earn income, how they pay taxes, how the government provides infrastructure with tax revenue, and how it conducts monetary policy. The subject has to be defined in terms of the object of inquiry.”

“Charities are now working to give people in poor countries access to the Internet. But shouldn't we spend that money on providing health clinics and safe water? Aren't these things more relevant? I have no intention of downplaying the importance of the Internet, but its impact has been exaggerated.”

“The invention of the printing press was one of the most important events in human history.”

“I would go one step further and say that the willingness to challenge professional economists - and other experts - should be the foundation of democracy. When you think about it, if all we have to do is to listen to the experts, what is the point of having a democracy at all? Unless we want our societies to be run by a body of self-elected experts, we all have to learn economics and challenge professional economists”

“People 'over-produce' pollution because they are not paying for the costs of dealing with it.”

“Since the 1980s, we have given the rich a bigger slice of our pie in the belief that they would create more wealth, making the pie bigger than otherwise possible in the long run. The rich got the bigger slice of the pie all right, but they have actually reduced the pace at which the pie is growing.”

“If the world were full of the self-seeking individuals found in economics textbooks, it would grind to a halt because we would be spending most of our time cheating, trying to catch the cheaters, and punishing the caught. The world works as it does only because people are not the totally self seeking agents that free-market economics believes them to be. We need to design an economic system that, while acknowledging that people are often selfish, exploits other human motives to the full and gets the best out of people. The likelihood is that, if we assume the worst about people, we will get the worst out of them.”
