To begin with, there is a huge range of restrictions on what can be traded; and not just bans on ‘obvious’ things such as narcotic drugs or human organs. Electoral votes, government jobs and legal decisions are not for sale, at least openly, in modern economies, although they were in most countries in the past. University places may not usually be sold, although in some nations money can buy them – either through (illegally) paying the selectors or (legally) donating money to the university. Many countries ban trading in firearms or alcohol. Usually medicines have to be explicitly licensed by the government, upon the proof of their safety, before they can be marketed. All these regulations are potentially controversial – just as the ban on selling human beings (the slave trade) was one and a half centuries ago.
There are also restrictions on who can participate in markets. Child labour regulation now bans the entry of children into the labour market. Licences are required for professions that have significant impacts on human life, such as medical doctors or lawyers (which may sometimes be issued by professional associations rather than by the government). Many countries allow only companies with more than a certain amount of capital to set up banks. Even the stock market, whose under-regulation has been a cause of the 2008 global recession, has regulations on who can trade. You can’t just turn up in the New York Stock Exchange (NYSE) with a bag of shares and sell them. Companies must fulfil listing requirements, meeting stringent auditing standards over a certain number of years, before they can offer their shares for trading. Trading of shares is only conducted by licensed brokers and traders.
Conditions of trade are specified too. One of the things that surprised me when I first moved to Britain in the mid 1980s was that one could demand a full refund for a product one didn’t like, even if it wasn’t faulty. At the time, you just couldn’t do that in Korea, except in the most exclusive department stores. In Britain, the consumer’s right to change her mind was considered more important than the right of the seller to avoid the cost involved in returning unwanted (yet functional) products to the manufacturer. There are many other rules regulating various aspects of the exchange process: product liability, failure in delivery, loan default, and so on. In many countries, there are also necessary permissions for the location of sales outlets – such as restrictions on street-vending or zoning laws that ban commercial activities in residential areas.
Then there are price regulations. I am not talking here just about those highly visible phenomena such as rent controls or minimum wages that free-market economists love to hate.
Wages in rich countries are determined more by immigration control than anything else, including any minimum wage legislation. How is the immigration maximum determined? Not by the ‘free’ labour market, which, if left alone, will end up replacing 80–90 per cent of native workers with cheaper, and often more productive, immigrants. Immigration is largely settled by politics. So, if you have any residual doubt about the massive role that the government plays in the economy’s free market, then pause to reflect that all our wages are, at root, politically determined (
Following the 2008 financial crisis, the prices of loans (if you can get one or if you already have a variable rate loan) have become a lot lower in many countries thanks to the continuous slashing of interest rates. Was that because suddenly people didn’t want loans and the banks needed to lower their prices to shift them? No, it was the result of political decisions to boost demand by cutting interest rates. Even in normal times, interest rates are set in most countries by the central bank, which means that political considerations creep in. In other words, interest rates are also determined by politics.
If wages and interest rates are (to a significant extent) politically determined, then all the other prices are politically determined, as they affect all other prices.
We see a regulation when we don’t endorse the moral values behind it. The nineteenth-century high-tariff restriction on free trade by the US federal government outraged slave-owners, who at the same time saw nothing wrong with trading people in a free market. To those who believed that people can be owned, banning trade in slaves was objectionable in the same way as restricting trade in manufactured goods. Korean shopkeepers of the 1980s would probably have thought the requirement for ‘unconditional return’ to be an unfairly burdensome government regulation restricting market freedom.
