Why is this wrong?

When the minimum wage change was being debated, I saw this tweet pop up from Duncan Garner.

Simon Bridges admits WINZ is there as a backstop if wages are too low. Can you believe it?

After the tweet follows a range of comments about corporate welfare etc etc.

This is all well and good, however I’m not sure I agree.  As I have said previously, I don’t agree with the minimum wage being used as a way of ensuring income adequacy (*,*,*).  If our true goal is to help those that are the “worst off” in society, than a direct minimum income – something that would be provided by WINZ – is the most direct means of doing this.  It sounds to me that Simon Bridges may have also been making that point (although we can argue about the degree and level of any said minimum income).

Now here is the kicker, people want to differentiate between the deserving and “undeserving” poor by using a minimum wage instead of transfering across a minimum income.  If we have to admit that transparently, does that seem fair, does that seem just?  These are the sort of question we should be asking ourselves, and society more generally, but they seem to have been missed in this situation – with people just looking for a reason to attack Simon Bridges.  Disappointing.

Note:  Via Economist’s View, Christina Romer on minimum wages.  The favoured solution over there tends to focus a lot more on the labour supply response than a strict minimum income/negative income tax would – and this is because it involves a broader set of redistributionary policies, rather than just the existence of a security net.  As you know, my focus tends to be on the security net issues with a pointer towards broader restribution given the rising potential for labour saving technolgy (*,*,*) – something that the Economist had a good piece on recently.  Remember, “potential parteo improvements” require redistribution for no-one to be worse off, there is no mystical tendency.

A point on crowding out

The idea of crowding out mentioned here appears to have made some uncomfortable.  On the face of it, people may feel that this sort of conclusion would mean that I agree with this sort of statement from Neil Ferguson (I don’t):

You can’t be a monetarist and a Keynesian simultaneously—at least I can’t see how you can, because if the aim of the monetarist policy is to keep interest rates down, to keep liquidity high, the effect of the Keynesian policy must be to drive interest rates up.

And it might give the inference that I disagree with Sumner here (I don’t):

I hope other bloggers will adopt DeLong’s enlightened approach.  Then we might finally be able to have a sensible debate over fiscal policy, instead of a inane shouting match between intellectually bankrupt “paradox of thrift” arguments and empirically unfounded “crowding out” arguments.

When I mentioned crowding out in that context, I was merely saying “hey, increased government demand is increased demand” … I was arguing against the idea that is publically being taken from MMT (although I am sure the authors are being a bit more careful) that for some reason a higher deficit would lower interest rates, and the fact that in trying to make themselves seem different from the mainstream MMT authors appeared to be willing to let this mistaken view become accepted.

[Note:  The argument they seem to have is that, if you increase the deficit AND then expand the money supply to accommodate it, you can lower interest rates … this is a different issue again, and requires a bit more of a description regarding the impact on inflation, which mainstream economics does through the central bank reaction function and inflation/NGDP target]

I emailed James about the Neil Ferguson piece saying the following:

Look at this.  Yar, an increase in G-T increases the term structure of real interest rate relative to where it would be, which in turn suggest that the central bank will indicate policy that involves a higher nominal interest rate to meet its inflation target.  But in terms of “stimulus” it doesn’t mean they are fighting – just that eqm interest rates are higher.  The Fed isn’t trying to “make interest rates lower” it is trying to meet its inflation target in the face of a negative demand shock.

This is consistent with the idea that, outside of the ZLB on interest rates central banks do fully offset the “demand” implications of fiscal policy (making it an issue of efficiency vs equity when choosing the size, scope, and actions of government).  When at the ZLB, and faced with the central bank that refuses to do anything, the fact that the government pushes up the “inflationary non-accelerating interest rate” by increasing its deficit is the very mechanism by which the stimulus is seen as “effective”.

As Sumner says in the aforementioned post, the “multiplier” associated with the deficit can be seen as an estimate of central bank incompetence – although I prefer to use the term central bank “conservativism” in the face of uncertainty.

Trade-offs run both ways

I see that discussions with financial market officials has seen the government come out and say that it is going to look at doing something about the interest rate premium in NZ.

Immediately you would expect me to nod and agree.  I’ve been talking about (*,*,*) a “high” real exchange rate, “high” interest rates, and low “competitiveness” stemming from these same and similar issues (although the margin and the level of rates are indicative of different issues … let’s leave that to the side) – and this is true.  But I’m not going to nod in agreement – at first brush this looks like another intermediate target, rather than a clear articulation of they “why” regarding interest rate margins and interest rate levels more generally.

Trade-offs run BOTH ways, we may have instituted policies on the basis that the cost of lower competitiveness etal is worth it for the benefit of greater “equity” in outcomes.  In the same way that I’m begging people who yell at the exchange rate to think of the issues – I beg the people listening to financial analysts who are talking about ways to “lower the cost of capital” to think of it in terms of the full implications for social outcomes.  A while back you would have heard me talking this way on productivity (*,*,*), and my severe mistrust of capital deepening (something that puts me on the fringe of many economists here tbh – and just to make sure that is clear).

Government is the body that society uses to help determine, and implement, the trade-offs that exist due to the inherent trade-off between some perception of equity and strict efficiency.  Let us keep these fundamentals in mind instead of targeting a price, or productivity, or some other “inbetween” function that obfuscates the trade-offs inherent in a decision!  Figure out the trade-offs that exist and getting society to express its desires (both hard tasks) is the way to go, and this sort of sidetracking through “targeting intermediate outputs” in an economy gets in the way of this.

My clearest post on this idea was when I discussed the recent writings by Mai Chen – full respect to her for putting out thoughtful articles on the issue, which is what allowed me to better articulate my problem with ALL those sorts of “aspirational” policy justifications (such as the ones I’ve previously criticised from the Greens – look, I’ve pretty much attacked every point on the political spectrum here 🙂 ).

Note:  This is a point where people will say “this is obvious” and roll their eyes and me – and then wink and say its just Matt ranting again (which is true).  But as well as being obvious it is fundamental – and given it is so fundamental to policy analysis I have to ask why reporting and suggestions of policy continually forgotten about it!

Hmm:  I wrote about remember equity and efficiency issues – in terms of economists recognising the importance of value judgments in 2008.  James was also talking about those issues then.  It is nice to see young “you” agreeing with old “you” on things!

The exchange rate as a price

Over on Rates Blog I’ve knocked up an entry on exchange rates.  In it, I spend a bunch of time just talking about “what an exchange rate is” – all with the aim of turning around and saying that given it is a price, we need to understand what it is telling us and why before we can go off and demand changes.

Effectively, the exchange rate is a symptom of things going on in the real economy – and policy needs to be focused on where these fundamentals may be hit by market and goverment failures, instead of a blanket criticism of the price.  I’d also note that there is a “barrier” to intervention in all this – we do need to actually have a fundamental understand of the issues before we put policy in place.  The persistently high real exchange rate is an issue that has caused some concern (*,*,*) – but “solving” any perceived problem here does not lead us to the conclusion of arbitrarily loosening monetary policy!

Note:  I suspect the comment section over there will look a bit like this – and so will hold off from reading till the weekend.

Update:  Scott Sumner covers similar ground by railing against “imbalances” as a concept – stop concentrating on the price, and start thinking about why the price has shifted.  Lars Christensen reiterates this before both of us.  In some sense, the Lucas Critique stemmed from this very idea.  I genuinely don’t understand why simply saying “let us think of why the price changed, and what the trade-offs are from this fundamental shift (and any policy to change it)” makes people so incredibly angry – but it does!  I have no social skills, and have a passion for discussing trade-offs, so I will never stop making this point – no matter how many nights in bars I have to put up with people yelling at me while I’m drinking my beer 😉

Two links that reinforce my priors

On bubbles (My point:  I keep hearing bubbles matter because “financial stability influences monetary policy” like it is a big idea … but really, no sh*t.  Government spending “influences” monetary policy.  So does competition policy.  They all change the time profile of the natural interest rate.  The fact is that we have monetary policy to manage monetary outcomes given these things – have other sets of government policy for other areas of government concern, and just try to base them in sound economics.)

On the minimum wage and long-run effects (My point:  Good to see actual work on given so many empirical estimates are for short-run effects – and even those show pain to the young and unskilled even if the aggregate figure isn’t statistically significant – reminds me of McCloskey).

In a time and a place where I have both time and a place to do so – I will post on these.  Hopefully.

New Zealand’s sexiest economist for 2013 is …

As we all know there are few things sexier than economics.  And it seems this applies to New Zealand economists as well with a massive 407 votes cast in the “New Zealand’s sexiest economist poll”.  This was especially impressive as voting was via IP address, meaning that many large organisation could only cast one vote.  This turnout heavily exceeded my initial estimate of 6 votes – implying that not only did my vote model fail to pick the Global Financial Crisis, or the value of the New Zealand, it also failed to actually estimate the number of votes the poll would receive.

After frantic voting the champion was … Darren Gibbs with 97 votes (24%)

Darren Gibbs – Deutsche Bank

Darren Gibbs – Deutsche Bank

This was an impressive performance, and no doubt shows the depth of appreciation for both Darren’s looks and his application of economic ideas and concepts.

In second place was Donna Purdue with 91 votes (21%).  She receive wide ranging support from the economist and non-economist community, and was constantly threatening for first place.

Eric Crampton (3rd place) and Gareth Kiernan (5th place) made an early run during the first day of voting, however both fell off the pace as the voting went on.  Shamubeel Eaqub lived up to his reputation as a dark horse, pulling in a number of votes on the final day to take out 4th spot!

Shamubeel and Jean-Pierre de Raad may feel aggrieved, as by putting down two members of NZIER I was splitting the NZIER vote (BNZ has a similar claim) – however, I would note that the combined NZIER vote still would have had them significantly off the pace set by Darren and Donna.

All in all, congrats to Darren, it was good to see that everyone received some votes, and economics was the winner on the day.
