Good on you Brazilian central banker

/2 Comments/in , , /by

Here is some sense talking from a central banker and trade representative from Brazil:

Senior Brazilian trade representative Mario Marconini from the Federation of Industries of Sao Paulo, says there’s a growing realisation from Brazilian businesses that trying to control the exchange rate is fruitless.

The long-term answer can only come from concerted international action to apply pressure on China to allow more flexibility in its exchange rate, Pundek says.

By removing China’s artificially low exchange rate, the massive trade imbalances created by that rate can be corrected.

This is point number one on our list of issues causing an imbalance (list at the bottom of this post).  I am loath to blame China for the whole imbalance – after all they are artificially selling their own stuff cheaply by devaluing their dollar.  However, currency pegging has to be seen as part of the PROBLEM in the current economic environment – not the solution!!

And on the idea of capital controls being fruitless, this becomes obviously when we look at one very simple fact – there has to be DEMAND for the capital for it to flow in.  The fact people want to lend is only half the story, people inside the country have to be willing to borrow at the given interest rate.  This is a little fact that seems to be continuously ignored pretty much everywhere …

California knows how to ban stuff

/10 Comments/in , , , , , , /by

The California Energy Commission, in all their wisdom, have decided that the best way to encourage energy conservation is through imposing compulsory energy efficiency standards on TVs – in other words they are banning what they deem to be ‘energy inefficient’ TVs. They are the first state in the US to implement such a measure.

The aim of the intervention is to reduce electricity demand and hence avoid the need to build new power plants to meet this demand. In this sense, the Commission perceive the building of power plants to be a negative externality, presumably as the cost of building is reflected in the per-unit price of electricity for all users.

I take issue with this ‘externality’. For example, if a lot of consumers suddenly started demanding ‘Thierry Henry is God’ t-shirts, such that the price increased, should I feel aggrieved that the action of others is affecting the price I must pay for such a worthy product? No, that is how the market works.

Putting aside my scepticism, let’s assumes that the externality is a genuine one. What might be a superior way of discouraging consumption?

Bans are a blunt tool. From an economic efficiency perspective, you should first try and use prices to incentivise behaviour. High demand for electricity is only ever a problem over relatively short periods. For example, in New Zealand the peaks occur on weekdays in the morning as people wake up and in the evenings as people go home. In hotter climates, the peak typically occurs at the hottest part of the day as air-con works its magic. Hence one might try to charge higher prices at times of high demand to discourage consumption (and hence avoid the need to invest in new power plants). There are electricity meters that are capable of facilitating such differentiated pricing and indeed they are being rolled out in California as we blog.

Under the differentiated pricing scenario, consumers are paying the ‘true’ cost of electricity, so even if they continue to consume at high levels, one should be indifferent to building a new power station as the externality has been internalised.

The obvious perverse incentive that arises from the ban is that consumers will simply purchase their televisions out of state, knowing that they can get a better range of TVs to better suit their individual needs at more cost-effective prices.

It is far more preferable to keep consumer choice open and simply make consumers fully pay for their choice through efficient pricing (assuming that an externality exists in the first instance).

Health Legislation: a carbon emitter?

/2 Comments/in , , /by

As speculated by some over the weekend, and confirmed today by the Economist, Copenhagen currently appears to be nothing more than a venue for which policy makers will agree to consider a future agreement on Carbon Emissions.

Undoubtedly there exist links between the U.S.’ relaxed approach to the summit and the Obama administrations efforts to pass universal healthcare; for the latter to pass the support of those contributing to the former is required. This is nothing new. What is interesting to note, however, is that such an attitude to favor health over emissions has been indirectly present within the U.S. for some time.

Earlier this year Boston became the second city (following San Francisco) to pass legislation banning the sale of cigarettes in ‘drug’ stores.  Within this legislation there exists a further directive restricting the sale of cigarettes on college campuses. This is where things become interesting. Consider a representative smoker. The impact upon this agent from said legislation results in further effort (i.e.; distance traveled) to obtain cigarettes. As such, the ‘carbon footprint’ of each cigarette has increased within the city of Boston; not too mention the shadow price of the cigarettes themselves.

The question is now posed; are carbon emissions an indirect consequence of health legislation?

Cunliffe on Labour’s shift in monetary focus

/17 Comments/in , /by

David Cunliffe has done a guest post on the Rates Blog looking at Labour’s change in monetary policy … policy. [We have discussed this here, here, and here already].

As far as I can tell (tell me if I’m wrong), the content of the post boils down to this paragraph:

More importantly, acting alone it has not achieved inflation control alongside reasonable stability of exchange rates and money supply. Combined with an imbalanced tax structure, high real interest rates helped suck in hot money that drove the housing bubble.

Now, I don’t know why he’s mentioning the money supply unless he’s going back to inflation – so lets ignore that.  Exchange rate stability is not important – if the dollar is moving because commodity prices are moving (which they have been) then it helps to stabilise movements in the value of export prices.  This is a good thing.

So we are left with the housing bubble.  I commented on the post with this:

Imbalanced tax structure – yes.

High interest rates – no.

An imbalanced tax structure with a lower OCR would have lead to a larger housing bubble. We are a small open economy, the supply of credit is infinite – the housing bubble stems from credit demand, which is declining in the OCR.

This is something people forget.  We are a small open economy.  The supply of credit at the world interest rate is infinite, no matter what our OCR is.  As a result, everything falls back to our “demand curve”.  Demand for housing credit is falling in the domestic interest rate – therefore, if our RBNZ increased the opportunity cost of bank lending by lowering the OCR it would lead to less borrowing to fund housing relative to otherwise.

We cannot blame monetary policy for the housing bubble (unless we feel they should have increased interest rate more).  I remember BERL making the same claim a while back, I was a bit unhappy with it then and I still am now.

Translating Labour’s goals for monetary policy

/13 Comments/in , /by

Labour has stated four goals for their special monetary policy.  Let me discuss what these mean in turn. [Note we already have two posts on this issue today].

Labour goals were:

  1. a stable and competitive exchange rate;
  2. reduced interest rates for businesses and home owners;
  3. continued priorities of price stability and low inflation;
  4. to guard against expectations of price rises.

So, with goal 1 they want to reduce the flexibility of NZ$ prices, which will lead to higher unemployment and a worse allocation of resources.  Furthermore, they want to keep the dollar low which implies subsidising exporters to the cost of households in the short-term.

With 2 they want to punish savers.

And with 3 and 4 they want to contradict themselves – as by limiting price flexibility and holding the exchange rate and interest rates down they WILL drive an increase in inflation expectations, dump price stability, and remove any chance of a low inflation environment.

Discussing inflation targeting and our exchange rate concerns

/3 Comments/in , , /by

In a recent speech (ht Rates Blog) Goff committed to destroying monetary policy independence and damaging the New Zealand economy if he gets into power.  That is all well and good.  However, I think part of the reason this issue has occurred is because of a lack of understand around the necessity of monetary policy independence and inflation targeting, and how all these other factors (like the exchange rate) are determined.  Lets discuss them a little bit here:
