Alerted to it by Peter Sinclair, this week I read Ezra Mishan’s 1967 (and frequently reprinted up to 1993) book The Costs of Economic Growth. It’s a short, polemical book, and the overwhelming impression you get is that the author was a grumpy chap not at all happy about modern life. Especially in cities. Too much noise, too much dirt, too many people, too much traffic, above all too much traffic. I’m not entirely sure I’d want to have been seated next to him at dinner.
The Costs of Economic Growth (Pelican)
Still, there’s a lot to like in the book. It has some excellent sections on the Coase theorem; on its non-applicability in many situations of environmental externalities because the transactions costs of negotiation are so large; and of the way the legal framework, in defining the status quo, shapes the outcome. If the law does not protect the interest of inhabitants in clean air, polluters will have no incentive or need to negotiate. Mishan in fact calls for general amenity rights to be enacted in law, rather radical but think how much difference it would have made to pollution and emissions since the 1960s. He also wants private vehicles banned from city and town centres, which also seems a radical but basiclly good idea; as he points out, transport analysts too often think their job is to get the traffic moving, when it ought to be to get people moving.
He also points out the importance of the initial distribution of income: “The wealthier the party, the more likely it is that his, or its, favoured outcome will be the optimal outcome.” The reason is that relative wealth will affect the parties’ judgements about what they are willing to accept/pay in a negotiation. Generally, the book is clear – as economists often are not – that an evaluation of social welfare is not possible without taking initial distribution into account. The level and distribution of income are not separable. I might need to go on to read Mishan’s Welfare Economics.
A little bit of his dyspepsia is reserved for the way evaluations of policy only take account of what can be measured even if it is clear that effects that cannot be measured are nevertheless very important. He would like to “arrest the mass flight from reality into statistics,” he writes. He decries ‘growthmania’, “the fact that the fascination with index economics detracts attention from the broader aims of economic policy.” There’s certainly something in this, and indeed I increasingly think economists have to do much better at measuring the size of externalities rather than shrugging the collective shoulders. But, unlike Mishan, I’m for sustainable growth, not no growth.
Mishan died aged 96 in 2014. I’m glad to have filled a gap in my knowledge.
