UK incomes are decoupling from economic health

Has the typical family gained from the UK's growth since the 1970s?

On both sides of the atlantic, there has been a relatively long-running debate about the extent to which "decoupling" – the failure of typical household incomes to grow at a rate matching the increase in GDP – has occurred.

The classic treatment of the topic compares GDP per capita to the median family income, as Lane Kenworthy did for the USA:

The difference is clear, albeit not entirely unsurprising (what the graph shows is largely the result of the large increase in income inequality since the 1980s). Yet not everyone accepts that it demonstrates a real phenonmenon.

Kenworthy writes:

One objection is that the price deflator typically used to adjust GDP per capita for inflation differs from the deflator used for median family income. I’ve addressed that here by using the same deflator for both.

A second concern has to do with GDP per capita as an indicator of economic advance. Since the 1970s a larger portion of GDP has gone to replace old capital equipment and therefore can’t go to household income. Also, the number of persons has increased less rapidly than the number of households, so a per capita (per person) measure of GDP could mislead.

A third worry is that the income measure used to calculate median family income is too thin. If a growing portion of GDP has gone to employer benefits, that would help middle-class households, but it wouldn’t show up in these income data.

He addresses the second and third concerns by using a per-household measure, which includes in-kind payments and the effects of taxation. The result is a very similar graph:

This demonstrates, he says, that "decoupling is real and sizeable".

But what about the UK? Have we got the same problem? Yes:

All the data comes from the ONS, the inflation measure used is RPI, and both median and mean household income are taken measured from after the application of taxes and distribution of benefits.

Just as in the US, income growth for middle-class households has become decoupled from growth of the economy.

How the Lib Dems learned to love all-women shortlists

Yes, the sitting Lib Dem MPs are mostly white, middle-aged middle class men. But the party's not taking any chances. 

I can’t tell you who’ll be the Lib Dem candidate in Southport on 8 June, but I do know one thing about them. As they’re replacing a sitting Lib Dem (John Pugh is retiring) - they’ll be female.

The same is true in many of our top 20 target seats, including places like Lewes (Kelly-Marie Blundell), Yeovil (Daisy Benson), Thornbury and Yate (Clare Young), and Sutton and Cheam (Amna Ahmad). There was air punching in Lib Dem offices all over the country on Tuesday when it was announced Jo Swinson was standing again in East Dunbartonshire.

And while every current Lib Dem constituency MP will get showered with love and attention in the campaign, one will get rather more attention than most - it’s no coincidence that Tim Farron’s first stop of the campaign was in Richmond Park, standing side by side with Sarah Olney.

How so?

Because the party membership took a long look at itself after the 2015 election - and a rather longer look at the eight white, middle-aged middle class men (sorry chaps) who now formed the Parliamentary party and said - "we’ve really got to sort this out".

And so after decades of prevarication, we put a policy in place to deliberately increase the diversity of candidates.

Quietly, over the last two years, the Liberal Democrats have been putting candidates into place in key target constituencies . There were more than 300 in total before this week’s general election call, and many of them have been there for a year or more. And they’ve been selected under new procedures adopted at Lib Dem Spring Conference in 2016, designed to deliberately promote the diversity of candidates in winnable seats

This includes mandating all-women shortlists when selecting candidates who are replacing sitting MPs, similar rules in our strongest electoral regions. In our top 10 per cent of constituencies, there is a requirement that at least two candidates are shortlisted from underrepresented groups on every list. We became the first party to reserve spaces on the shortlists of winnable seats for underrepresented candidates including women, BAME, LGBT+ and disabled candidates

It’s not going to be perfect - the hugely welcome return of Lib Dem grandees like Vince Cable, Ed Davey and Julian Huppert to their old stomping grounds will strengthen the party but not our gender imbalance. But excluding those former MPs coming back to the fray, every top 20 target constituency bar one has to date selected a female candidate.

Equality (together with liberty and community) is one of the three key values framed in the preamble to the Lib Dem constitution. It’s a relief that after this election, the Liberal Democratic party in the Commons will reflect that aspiration rather better than it has done in the past.
