Remember, we can “overlabel”

Following the unfortunate death of a woman from drinking far too much Coke, there have been calls to label Coke.  I’m all for information, and that often makes me pro-labeling, but in this case I’m not … it is important to recognise that we are targeting providing information, and so we can “overlabel”.

A label gives information as an abstract concept, but it is costly to interpret and so the existence of a label is often taken as a signal, and used as a rule of thumb.  As a result, too much labeling of things could reduce the true information content – leading to people making more poorly informed decisions.

The solution?  There is a trade-off for the amount we label a given piece of food etc – and we need to accept that.  However, we can also make more detailed information and standards a necessary requirement to be on some sort of central website – so people who do want to take into account greater information can do so at a low cost.  I would also note that people that design easier to interpret labels which don’t sacrifice information are “shifting out the information curve” – this is a real productivity improvement, and these people are cool as a result.

The overall goal of the regulation is to “maximise information” so that people can take costs and benefits into account when they do something.  That should be the guiding principal – not saying people should have one thing or another.

Note:  Look, no need for me to go on about personal responsibility, or insult the woman about her life choice to get this result – which I’ve seen a bunch of.  We don’t know her life, preferences, or situation – so we shouldn’t suddenly decide that since it is a choice we wouldn’t make we should either ban the product or attack the choice.  I’ve noticed a lot of both, and its generally a bit disrespectful, which is also why I delayed this post until people stopped being rude.

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.

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!

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.

 

Remember the dollar is a price – work from there

Via James I see that the Financial Times has given a strange write-up of the RBNZ speech from yesterday (my view here).

The focus of the FT article is solely on the dollar, which in itself is cool as most of the speech was indeed on the dollar.  But they interpreted the comments a bit differently than I did.

First the exchange rate overvaluation relative to the terms of trade and productivity – yes, this has been the Bank’s view for a long long long time.  Of course this begs the question why, which I think is covered relatively briefly … and this is likely why we end up with differing interpretations.

So they go through ways that policy actions of a central bank may influence the exchange rate.  For some reason the FT means that they are planning to use a bunch of exciting tools to reach some sort of right value.  But lets start with this quote from the RBNZ:

Expectations of what central banks can deliver by way of exchange rates and output and unemployment remain excessively high. This is particularly the case in small open economies.

They are spending the speech discussing the tools they have at their disposal, how little they wil able to achieve with them, and how impractical many of the tools would be.  Again, if we actually though about what a real exchange rate is, and the fact that the RBNZ is talking about it being PERSISTENTLY overvalued in their speech, what matters is the fact that the high real exchange rate is a signal of underlying things in the real economy.  It tis a price, and like all prices it is telling us about fundamentals in the market – which are the actual things we are interested in!

This becomes pretty clear if we reiterate the part of the conclusion that the FT didn’t bold:

But further efforts to improve the level and productivity of capital that labour works with, to reinforce ongoing fiscal adjustment, to re-examine the factors that diminish and distort the incentives to save and invest, and to reduce dependence on the savings of others, have to be a major part of the solution.

FT seems to think the RBNZ is saying:

There are no simple solutions, Wheeler said, but it seems the favoured approach is some combination of lowering cash rates and offsetting the domestic effects via some sort of macroprudential policy

Reading earlier in the RBNZ’s speech they are saying that the OCR doesn’t have a clear impact on the dollar, and they adjust that to meet their inflation target (so not to target the exchange rate independently of it’s impact on inflation), and with regards to macroprudential policy they say:

The New Zealand economy currently faces an overvalued exchange rate and overheating house prices in parts of the country, especially Auckland. The Reserve Bank will be consulting with the financial sector next month on macro-prudential instruments. These instruments are designed to make the financial system more resilient and to reduce systemic risk by constraining excesses in the financial cycle. They can help to reduce volatile credit cycles and asset bubbles, including overheating housing markets, and support the stance of monetary policy, which could be helpful in alleviating pressure on the exchange rate at the margin.

So they are saying they will use macroprudential tools for financial stability reasons – and on the margin this might lower the real exchange rate as well.

They are so far from saying that they will use the OCR and macroprudential tools to “target the dollar” that it hurts me to see this inference turn up.

Also it is interesting to see the FT feel that macroprudential tools in NZ are very unclear:

What does he mean by using macroprudential instruments? Capital controls? Raising reserve rates to offset the effect of cutting interest rates? Those are a couple of ideas we’ve heard floated around but no-one seems very confident of how to interpret that.

When Grant Spencer from the RBNZ has actually come out and stated what they are and what their purpose is – maximum LVR’s and risk-weighting adjustments in capital adequacy ratios to deal with issues of systemic risk.  Anyone who has spent anytime looking at the RBNZ would know exactly how to interpret that 😉

Tbf, the RBNZ does explicitly mention the dollar not being a “one-way bet” – and this may be because they are concerned there could be a “bubble” in the value of the NZ dollar.  This comes in here:

The Reserve Bank is prepared to intervene to influence the Kiwi. But given the strength of recent capital flows, we can only attempt to smooth the peaks of the USD/NZD exchange rate; we cannot determine the level. When the NZ dollar is coming under upward pressure, we want investors to know that the Kiwi is not a one way bet.

This jawboning is cool, but I fear the FT is reading too much into these comments.  The speech was as much about educating us New Zealanders about the limited ability of the Reserve Bank to influence economic variables as it was about talking traders out of a perceived “asset price bubble in the NZD”.

RBNZ gives its frame for the debate on manufacturing and the exchange rate!

Excellent.  The RBNZ has come out and discussed what is going on with manufacturing, what monetary policy can achieve, and the fundamental point that any “failure” stems from distortions in the domestic economy – not from flexible inflation targeting.

Globalisation, outsourcing, and international supply chains, along with competition from low cost producers and rising global demand for services, mean that the relative importance of manufacturing has been declining in all but the poorest countries for the past 40 years. New Zealand is no exception. Although the exchange rate is an important headwind for some manufacturers, the overall relative decline in our manufacturing sector is much more than a simple exchange rate story. Looking ahead, total manufacturing output is expected to increase significantly as a result of the NZD$30 billion Canterbury reconstruction.

There are no simple solutions available to the Reserve Bank on the exchange rate challenges we face. The causes of the over-valuation partly lie in the spillover effects of policies in countries most severely hit by the global financial crisis. The Bank will intervene when circumstances are right. We will use the OCR as circumstances require and we’re exploring the scope to use macro-prudential instruments that address increasing challenges to financial stability associated with ongoing increases in house prices, and that can also support monetary policy. But further efforts to improve the level and productivity of capital that labour works with, to reinforce ongoing fiscal adjustment, to re-examine the factors that diminish and distort the incentives to save and invest, and to reduce dependence on the savings of others, have to be a major part of the solution.

Unsurprisingly I agree with this heavily, and I’m really glad to hear these guys come out saying these things 🙂

I’ve been wanting the RBNZ to reframe the debate on monetary policy for some time.  And I’m also in agreement with the fact that manufacturing is shrinking (in a way akin to the agricultural revolution) and that this is likely to continue!

The Bank has written on, and heavily researched, all these things in the past – research that has helped me build a view that is no doubt similar to its view.  It is nice to see them come out and say it all directly … it also means that I feel more comfortable that I haven’t misinterpreted them in the past 😉

The one note of difference is that I am uncertain whether I believe in the slight tacit suggestion of a currency war here, something I’m not sure I agree with.  However, they may well be using a very specific view that there is currently a “bubble” in the NZ dollar.  If there has ever been a “bubble in the New Zealand currency” I suspect that the best case can be made around now – and they will have a much better handle on that than I ever will.
