"Predistribution", a concept that Ed Miliband discusses in his interview  in this week's New Statesman, is one that is easily mocked. But it represents an idea that is central to the challenge of building a fairer economy - that the state, rather than merely ameliorating inequalities through the tax and benefits system, should act to ensure that they do not arise in the first place. (See this recent piece  by Yale professor Jacob Hacker, the man who coined the term). To this end, it should legislate for policies such as a living wage and introduce curbs on predatory energy and rail companies, pursuing what Miliband's consigliere, Stewart Wood, has called  a "supply-side revolution from the left". As he wrote in a piece earlier this year:
We will need different kinds of banks and stronger competition in the banking industry; corporate governance reforms to incentivise good ownership models and longer-term business strategies; ensuring that companies see the continuing upskilling of their workers as an obligation and not simply a luxury; and the courage to challenge vested interests in the economy that charge excessive prices for energy or train fares and squeeze families' living standards.
In his speech to today's Policy Network conference, Miliband will elaborate on this theme, stating that while redistribution will remain a "key aim of the next Labour government", a greater focus on predistribution is needed. He will advance two main arguments for this claim. Firstly, that the failure of the last Labour government to reduce inequality proves that while redistribution is "necessary" it is "not sufficient", and secondly, that the fiscal constraints a Labour administration will face (based on current forecasts, it would inherit a deficit of £96.1bn or 5.8% of GDP) mean that it will be not able to increase tax credits (the last Labour government's primary redistributive instrument) in the manner that Tony Blair and Gordon Brown did.
The great strength of predistribution is that it does not cost the state a penny to pursue. Rather than relying on taxation to narrow the gap between the rich and the poor, Miliband will harness the instruments of legislation and regulation. Rail companies, for instance, would be barred from raising fares by more than 1% above inflation. As he will say in his speech:
As with much of Miliband's "responsible capitalism" agenda, more detail is required (which, given that we're still not even halfway through this parliament, is hardly surprising) but the ambition is admirable. Under the rubric of predistribution, Labour can finally adopt the kind of policies that will have a transformative effect on the living standards of working people.
