Mariana Mazzucato's extremely strange economics

Mariana Mazzucato's got another installment of her rather strange economics in the paper. This is the follow on from the insistence that government funds all innovation. Here's she's decrying the rise of "finance" and how it doesn't actually develop the economy and thus, well, and thus politicians should do it all for us I think. One interesting little thought is that she doesn't seem to have understood Piketty:

Indeed, the origins of the financial crisis and the massive and disproportionate growth of the financial sector originated in the 1970s, as finance became increasingly de-linked from the real economy.

It's also true that Piketty doesn't really understand his own data either. Yes, there has been a rise in the wealth to GDP ratio and yes, it did start in the 70s. For the US and UK this was a rise of about 150% of GDP. And yes, this has almost all been in financial assets. So we can indeed say that finance has risen in importance as a part of the economy.

But what has also happened is that pensions savings have risen by 150% of GDP over this same time period. That is, that the rise of finance seems very closely correlated with the baby boomers saving for their retirements.

It's difficult to see this as a problem really.

Then there's this entirely bizarre point she makes:

In the attempt to "rebalance" economies away from speculative finance towards the real economy, there have been proposals to reform finance so that it helps to fuel more innovation. Various measures have been tried to help those few small and medium enterprises willing to go after difficult high-risk investments, the backbone of innovation. Yet these reforms have been inadequate, slow and incomplete, with the proportion of profits from quick trades in the financial sector, rather than long-run investments, rising not falling. And one of the key tools for long-termism, the financial transaction tax, has still not been applied.

She seems not to have read the EU's own report on the FTT (which I wrote about here). The EU itself states that the introduction of an FTT will reduce investment in business, so much so that the economy will actually shrink compared to where it would be without the FTT. So Mazzucato is apparently recommending a course of action, in order to increase investment, which we know will actually reduce investment.

It's an odd policy world she inhabits, isn't it?

The rest of it is just that we should have a Public Investment Bank and everything will be sweet. Which, given the things that politicians like to invest in (Olympics, HS2, Concorde, write your own list) is a very sweet but most misguided hope.
