I just readby Paul Allin and David Hand, a very nice overview of the issues in going ‘Beyond GDP’. It came out in 2014, about the same time as my , so unfortunately I’d not had chance to read it before writing mine. In the couple of years since, the momentum behind the agenda to go ‘beyond’ has certainly increased. This book is a very clear, and rigorous but non-technical explanation of the scope of the issues, and the state of play. As Allin and Hand describe, there has been a good deal of work on looking at alternative ways of defining and measuring ‘wellbeing’ directly, and at wider approaches to assessing whether or not society is progressing.

I am more cautious than they are about any survey-based direct measurement of wellbeing. There seems to be a lot still to understand about the psychology, and about how people’s judgements are formed. After all, we don’t just introspect, we’re also influenced by social context – have we just read an upbeat book about progress? or rather, just read the execrable Daily Express? I’m more with the programme when the book looks at how to (greatly) improve what we do now. For instance, report net national income per capita, not total GDP. Include income distribution and environmental measures. As they note, there are already statistics on many indicators that would give a richer picture of economic welfare. Jones and Klenow have a very nice recent paper on a single summary measure of aggregate economic welfare rooted in economic theory: it calculates a consumption equivalent measure combining income/leisure, distribution and life expectancy. This omits questions of environmental sustainability but good progress is being made on environmental ‘satellite’ accounts and natural capital measurement.
There are some important questions not addressed by Allin and Hand. They describe a proliferation of approaches to measuring wellbeing and indeed call for a thousand flowers to bloom. In my view, if there is no narrowing down of the options, the existing standard of GDP and the conventional national accounts will be far harder to dislodge. A new focal point is needed. (I have a paper on this out soon. Others – like Ehsan Masood in– call for a single index for this reason although for different single indices.) The reason is not tidy-mindedness, but rather the role that official economic statistics play in holding governments to account.
The other question ignored by all of what you could describe as the pro-wellbeing literature (not that I’m against well-being) is innovation. In disparaging GDP growth as a metric, they overlook the fact that GDP growth is not mainly about more shoes, food and vehicles of the same kind, it is mainly the introduction of innovations, from small changes in variety to profound new technologies like the smartphone or the personalised cancer treatment. GDP doesn’t measure these well, and there is a fuzziness as between quality change potentially reflected in prices and real growth, and unmeasurable consumer surplus. But innovation is a huge contributor to wellbeing and people will continue to like ‘growth’. No-growth is a non-starter outside authoritarian and autarkic polities.
These caveats aside, I really liked the book and it is well worth a read if you’re interested in this territory. As many people are – statistics is the new rock and roll.
