So far, so good. That's my verdict of the remaking of Labour under its new leader, Jeremy Corbyn. I'll say more about the big picture later in the week, after Mr Corbyn's speech later today. This time I want to focus on economics and the performance of the Shadow Chancellor, John McDonnell, who spoke yesterday.
Like Mr Corbyn, Mr McDonnell is a serial rebel and a political outsider - and he is very much Mr Corbyn's right hand man. That is why he was given the job of Shadow Chancellor over the much more politically correct Angela Eagle. Both Mr McDonnell and economics are central to the Corbyn project.
The first thing to note is the new regime's ambition in taking on economics. The previous leader, Ed Miliband, was a bit embarrassed to talk about economic policy. He did not try to defend the previous Labour government's economic policies, nor seriously criticise them for matter, in spite of the opprobrium being dumped on them by the coalition parties. He was late in developing his own economic proposals, and when these came out, they appeared to be "austerity-lite", and not seriously challenging the government's narrative.
Mr McDonnell, on the other hand, wants to take control of the economic narrative. He is enlisting the help of heavyweight economists to both support his own plans, and to undermine the government's version of events. In this he is capitalising on a remarkable fact. Academic economists have been very critical of government policies and "austerity" generally. Indeed government policy seems to be more based on 200 years of Treasury orthodoxy than modern economic insight. This is an opportunity to undermine the government's reputation for competence, and make it look ideological.
Labour is still left with the two paradoxes of anti-austerity economics that I referred to in a previous post. The first is that by opposing austerity Labour will have to make its peace with the global financial markets that it so despises. Mr McDonnell tackled this head-on in his speech, and in an interview with the Guardian newspaper last weekend. He has nominally adopted the government's trajectory for reducing the UK's fiscal deficit, with its aim of bringing it into surplus by 2020. With a huge rider: he will exclude borrowing to fund capital investment. Depending on how loosely "investment" is defined, this is perfectly sensible public policy, and not, in fact, very different from Mr Miliband's. It reduces dependence on international finance - remembering that the Bank of England's Quantitative Easing policies may come to the government's aid if the economy takes a turn for the worse.
There is, of course, a problem. It means signing up to austerity as most people understand it. And yet opposition to austerity remains his rallying cry. One of the many weaknesses of the left is its love of abstract nouns, especially as things to oppose - austerity, neoliberalism, inequality, and so on. Ordinary working people don't understand what they are on about, but the activists work themselves up obsessively - and at the moment austerity is public enemy number one. But Mr McDonnell and Mr Corbyn have an ingenious answer to this: just change the meaning of "austerity".
To them, the word now applies not to tightening the government's finances overall, but to cuts and tax rises that might affect low and middle income workers. There will be cuts, said Mr McDonnell, but not to the numbers of policemen, nurses or teachers. Instead the cuts would be to "corporate welfare" - tax breaks to businesses, as well as raising taxes on the rich. He was careful not to be too specific about all this.
There are some pretty solid grounds for scepticism here. Mr Corbyn has brandished the figure of £93 billion for corporate welfare, a figure conjured up by the Guardian. Mostly these are allowances or direct support for investment, exports and research and development - all things Labour will want to encourage. And the small print of the Guardian's report suggests not that this is low hanging fruit waiting to be plucked, but that it is, to switch metaphors, a rather overgrown hedge that can be trimmed a little. There is reason to doubt how easy it will be to target other measures to raise taxes, or clamp down on avoidance, without collateral damage to the small and medium sized businesses that the economy so needs. This is what undid Francois Hollande's Socialist government's attempt to do much the same thing.
But it isn't nonsense either. Big business, and the pampered elites that run them, are not a benign force these days. They contribute to the hollowing out of much of the economy by destroying middle ranking jobs and sucking the soul out of towns and villages away from the main commercial centres. They also siphon profits out of the economy rather than reinvest them. Labour will do well to be wary of big business, unlike the earlier regimes of Tony Blair and Gordon Brown. But finding policies that will tilt things against big business without damaging the wider economy will not be easy. I think that tax treatments for intellectual property and debt interest are a better place to look than the Guardian's corporate welfare list. And international cooperation on corporate tax avoidance will help (especially if we can move to unitary taxes, such as the US states apply among themselves). But such policies will take time.
All this takes us into the territory of my second paradox for anti-austerity economic policy. It calls for more economic growth, and yet bears down on much of the private business that will be needed to generate it. This will be the next challenge for Mr McDonnell and his colleagues. It is fair enough to bear down on many businesses, especially the giants. But Labour also needs to show encouragement and support for more positive businesses, through investing in support infrastructure, improving access to credit for genuine investment, improving public procurement, and through reducing the burden of petty regulation. As yet I see no sign of this - but it is early days.
I remain highly sceptical of the new Labour project. But its leaders have made a competent start, and there is undoubted fresh air. The floor is still theirs.
