I would have keep track of a large number of lefties who were not Labour members and also in possession of extreme views. I would then follow their exploits to see if they were admitted to the Labour party. Since the Labour party now has lots of members and since vetting is hard, I could be guaranteed a regular supply of suitable candidates to run smear stories about by simply cross referencing twitter searches for "labour" and things like "zionism" or "isis".
Extra points can be gained for making such stories are regular occurrence, bonus points for getting gullible fools to read this as some kind of pattern.

Warhead Free Trident
Lots of people seem to be describe the idea of keeping the submarines but not having the warheads as an awful idea. I'm not so sure the issue is quite as clear cut as all that. The Trident debate generally goes along the following lines:
If we were to keep the submarines it would mean the UK would retain the ability to re-arm if global geopolitics warranted such a change. An awful lot of this depends on specifics: Do we keep the warheads in storage? Do we dispose of the warheads but maintain the ability to produce them in future. What this debate amounts to is a debate about how long it should take to switch the UK's nuclear deterrent back on, if we throw the off switch.
Ultimately, what we have here is a way of providing a step in what I think can universally be agreed is the right direction without ruling out a return should the situation warrant it. It seems like a reasonable argument to make and it's a depressing indictment of British politics that what appears to be both a reasonable and pragmatic suggestion is dismissed so readily and vehemently.
Anti: Nuclear weapons are awful, we should make a positive gesture towards a more peaceful world and get rid of them.If we accept the premise that the current geopolitical situation doesn't warrant the UK having an active nuclear deterrent (which seems reasonable) but that this situation could be subject to change (which also seems reasonable), a warhead free submarines plan could potentially satisfy the needs of moderates on both sides of the debate.
Pro: That's naive, we all agree that nuclear weapons are awful but other nations have them and might use them, so we need them as a deterrent so people know that if they shoot at us, we can shoot back.
Anti: But the world has changed, in the cold war we always worried about the USSR, but its gone and Russia doesn't really look like it's going to try anything these days and other nuclear armed states have neither the capacity or the desire to attack the UK.
Pro: But the political situation could change, although the situation looks reasonably benign now, it could quite easily get worse with a few political changes.

Defining Austerity
The term "austerity" has an awful lot of people confused, so I thought I'd do a quick post on the subject explaining it from an economic point of view. The first point to get out of the way is that the kind austerity being discussed by and large is _fiscal_ austerity, relating directly to policy decisions by the government on spending and taxation. It's not the only thing we can deem as "austerity", but it's generally what people have meant in discussing it over the last 6-7 years. What follows simplifies the details a little, but makes a pretty good rough guide.
First we need to come up with the concept of aggregate demand (Written as the letter Z). We specify
Z = C + I + G
That is total demand in the economy is equal to demand for private consumption (C), plus investment demand (I), plus government demand (G). We then add total output (or GDP, written as Y) to the mix. Because total demand equals total output we can move on to getting an equation that crops up a lot in economics (the goods market equation in IS-LM):
Y = C + I + G
Finally, we add in taxes, we place taxes next to consumption to denote that they act to reduce consumption:
Y = (C-T) + I + G
Now that we have our equation, we need to start to talk about fiscal policy by looking at the two variables in this equation that are within the gift of the government: government demand (G) and taxes (T). Any government policy that acts to raise Y in this equation, tax cut or spending rise, is fiscal expansion, anything that acts to reduce Y is a fiscal contraction (aka what we can call austerity).
That, in a nutshell is how economist/econoblogger community defines "austerity", although there is a couple of final complications. The first in that GDP (Y) is a moving target that is usually growing at a slow trend rate. In that sense we do need to look at how the two government controlled components (G and T) behave relative to overall growth of output, G growing more slowly than overall output can be considered austerity in this sense (indeed, in order to make this happen you would probably need to make cuts). The second which relates to the moving target nature of GDP is that determining with any precision whether a policy is expansionary or contractionary can be difficult as you can't be sure what GDP growth holds, we can for example guess that the coalition's raising of the tax threshold was expansionary as it was way beyond any regular inflation/wage related expansion but it would be hard to define what the precise figure for said expansion was.

The UK and the Liquidity Trap
I had an interesting
exchange of tweets with Nick Shaxson and the hated Sam Bowman of the ASI (or is
that Sam Bowman of the hated ASI) on the subject of companies hoarding cash.
Sam suggested that companies hoarding cash was not a problem, I suggested that
it would be in a liquidity trap to which he asked if the UK is or was in a
liquidity trap (or if such a thing really exists). I think it is the case that
we are essentially in a form of liquidity trap, so what follows is the way I
intuit the basic IS-LM model with regards to the UK economy. I'd also add that Krugman
So first off, the
basic IS-LM model is based around a static closed economy with a goods market
and a money market. In the money market we find an equilibrium between the
demand for bonds that give a return at an interest rate (i) and cash. The goods
market is governed by good old Output(Y) = (C - T) + I + G with the level of
investment being determined by the interest rate hence giving us the downward
sloping IS curve. A liquidity trap occurs when we get a situation a bit like
the one below with the yellow lines, in the money market demand for money is so
low at the given level of output that consumers are indifferent between holding
cash and bonds. I've also put a more normal scenario where we are above the ZLB
in green.
Translating the
model into the real world can be a bit tricky, but I think it's reasonable to
look at the rate on government debt as a good guide to where interest rates are
at. In terms of money supply, I think here we can interpret moves by the bank
to loosen policy (lower interest rates, QE) as shifting the money supply curve
right. Finally, in terms of growth, I don't think we should necessarily assume
that growth shifts the IS curve right, instead I'd interpret this as a sign of
how "hot" the economy is. We can see growth despite the kind of zero
lower bound equilibrium of the yellow and blue lines, shifts in
"output" in this diagram manifest through fluctuations in the overall
rate of growth. A low equilibrium output is seen in the form of slow growth,
excessive austerity could shift the IS curve left to the point of causing a
recession.
The liquidity trap I
describe here is one of output being depressed through keeping aggregate demand
low through austerity. The main place I see it here is in the money market
equilibrium, the low interest rates on what we might classify as bonds are a sign
of depressed output and a loss of economic potential, I think we are seeing the
results in the form of below trend output (see this from Simon Wren-Lewis). In
terms of other things that might justify us being in a liquidity trap, I think
we can also look at the two textbook insights:
- In a liquidity trap fiscal policy is very effective
- In a liquidity trap monetary policy is very ineffective
Both those insights
seem like a fair assessment of our current situation.

A Look at Corbynomics
There's lots of
discussion of what Jeremy Corbyn's economic plans are, so I thought
I'd put some of the major elements under the microscope. I should
add the disclaimer that because as it's clear to people who follow me
on twitter, Corbyn is my favoured candidate. I will try though to
keep my views as analytical as possible (although I do abandon
impartiality in the last section).
Deficit Reduction
If my reading of his
policy on deficit reduction is actually pretty conventional, the view
I've cobbled together is that while he believes we need to reduce the
deficit and ultimately stabilise debt/GDP but he believes we should
be far slower and more careful in reducing the deficit, not setting
an arbitrary time frame. This seems to appreciate something that few
politicians realise and that is that we have far less control over
the economy that we actually do, a suitable metaphor might be
attempting to reach a destination by sail, sailing close to the wind
looks like a more direct route but might ultimately end up
counter-productive as you may end up being blown off course.
The reason that this is
a sensible approach is that borrowing is currently very cheap and we
appear to be at the zero lower bound in terms of interest rates,
textbook macroeconomics tells us that fiscal policy is very effective
in this kind of situation which is a pretty good case against
austerity and for borrowing to invest (something that Jeremy also
proposes).
Tax Raising
I'm not so keen on this
section. Richard Murphy is quite confident of the figures he's put
forward here although my hunch is that they are optimistic, I'm not
sure if the figures are as large as is said and even if they are I'm
not sure how easy it would be to get out hands on this money. That
said, there are still some good proposals, country by country
reporting in particular would be very useful.
He also talks about the
£93 billion in corporate reliefs and subsidies, this is also
something I'm not so sure about. I'm sure there are some of these
that could be cut, but an awful lot of them seem to be things we
should be encouraging (investment and R&D allowances for example)
and there are some that could cause serious problems for the way some
businesses operate.
All in all I think the
tax raising possibilities mentioned in the document are very
optimistic.
The Helicopter
The proposal that's got
most people talking is his QE for the People idea, which appears to
be getting the Bank of England to print new money which is then spent
on infrastructure. The policy looks a little like what's called
"helicopter money", an idea originally proposed by Milton
Friedman and has been discussed more recently by people like AdairTurner, Mark Blyth, Eric Lonergan and Simon Wren-Lewis and Willem Buiter. The
main difference is that they have all treated it as a monetary policy
instrument, an additional weapon to be put to use to get inflation
back on target when the interest rate isn't cutting it.
As a monetary policy
instrument the simplest way would be for a universal simple lump sum
payment to all adult citizens, this could both provide a rapid boost
to demand and the nature of the universal nature of the transfer
would mean the Bank of England remains independent. The problem with
using helicopter money on infrastructure is that it's really quite
difficult to time infrastructure projects in such a way that they can
raise aggregate demand. It can take years of preparatory work before
you start building a new road for example, this essentially means
that it would be little use as a way of rapidly raising raising the
quantity of money and aggregate demand in order to combat inflation.
The political nature of this new spending and money creation would in
effect create a second, politically controlled monetary authority
which would undermine the role of the Bank of England as the UK's
monetary authority (Tony Yates is good on this).
My overall opinion on
the helicopter money idea is that it's a good idea when done in the
right way, but that infrastructure QE is not a good idea and that
any National Investment Bank would be better financed through
conventional government borrowing. That said, one of the main
criticisms I've heard is that it would be inflationary doesn't really
stand up. A large enough amount this kind of QE could be
inflationary, but if inflation was to start to tick up you could
simply turn money taps off. An alternative and perhaps better way of
looking at QE for the people is to view it as a way of selling
expansionary fiscal policy to a debt averse public, this to me seems
to be what People's QE is really all about.
A Final Note
You might have noticed
that I am quite harsh on Corbyn in what I say, so the obvious
question arises: Why am I voting for him? Firstly, while I think
Corbyn's policies are flawed, I do not think they are policies that
can be dismissed out of hand, they are ideas that deserve to be taken
seriously. Corbyn's political opponents have not attempted to
developed a serious critique of his ideas, given that trust on the
economy is important for winning an election you would hope they
would be able to do this.
The second point is
that again while I don't like everything Corbyn is offering, his
policies seem on balance the best on offer. As I've said, there's
much to like about his fiscal stance and there are variations on
Peoples QE that could work effectively. He's probably promising more
than he can deliver, but it is at least a vision of a better future.

Labour and the Structural Deficit
On a recent leadership hustings hosted by Andrew Neil, the charge was made that the UK under Labour was running the largest structural deficit in Europe apart from Greece. The candidates answers unfortunately missed a very important point.
The large structural deficit in question only appeared as a result of taking into account data from after the crash. Before the crash, it was assumed that the UK economy was running at close to but slightly below capacity. With the arrival of the crash and the resulting deficit, that view was revised to assume that in fact the UK economy must have been running significantly above capacity.
The point here is that the structural deficit was the result of the way that estimates were constructed based on post crash data, not on estimates that were available before the crash. This is, I think something that should be emphasised by leadership contenders.
There are those who will say that we should nevertheless run a surplus on a just in case basis. To those people I would point out that running a surplus unnecessarily could have a serious cost in lost output and also that the UK national debt was low in 2007 and that despite the crash the UK never had any problem financing it's debts, the UK governments finances were in a good secure position before the crash.
As a final note I'll point out that, inflation, the traditional sign of an overheating economy was not present in 2007. The state of the UK economy in 2007 is something that has not been examined closely enough and does warrant further study.

An Unconvincing Argument from Liz Kendall..
Something I've been hearing from Liz Kendall and her supporters has been an argument along these lines:
Even if we disregard arguments about the zero lower bound, multipliers and the economic dividends from investment in things like infrastructure (and I don't think we should) there's still the plain simple maths of it all. According to the 2015 budget, total managed expenditure is £743bn, debt interest is £46bn (or £34bn if you count the APF), paying off every penny of debt interest would only allow us to increase spending by 6.5%.
More to the point, reducing debt by any serious amount would take a considerable amount of time. If we start from a debt of 90.6% of GDP, assume a 1% surplus and nominal GDP growth of 4%, it would for example take 13 years to half the outstanding national debt (as a % of GDP, another aside would be that running a 1% deficit would still see debt reduced by 29%). It would take a long time to see even small dividends from reducing the national debt.
It may be a good sound bite, but it's just not in any way sensible policy.
Update 22/6/15: Jonathan Portes posted a link on twitter to a more academic take on this subject at Vox EU.
"..there is nothing progressive about spending more on debt interest repayments than spending on the future of educating our children."I suspect it's an argument we'll hear repeated quite a lot because it has all the hallmarks a good bit of propaganda, it's short ,catchy, repeatable and has a kind of intuitiveness about it. The problem with it is that it doesn't have much merit as an effective policy.
