Collusion, retail petrol prices, and market activism

In New Zealand there has been an email going around suggesting that everyone should stop purchasing petrol from selected retailers (such as BP) in order to start a price war.

Now I accept that this doesn’t make much sense in the face of no collusion – which currently appears to be what is going on (h.t. No PC). However, if we did have collusion, how would this scheme work?

Interesting critiques from LAANTA

Over at the excellent LAANTA blog, Terence has written a couple of posts discussing issues I have raised here.

The first post covers our discussions on Utilitarianism. Fundamentally I think we have reached a point where our only disagreement stems from value judgments (specifically what we view as the fundamental measure of value, something I plan to write about separately another time) – which implies that his post is a good place for us to leave it.

The second post argues that goods and services taxes are infact regressive, contrary to my own musings. This is something I will discuss in this post.

Employer contribution and Kiwisaver

Tracy Watkins indicated that the National is in a pickle surrounding compulsory employer contributions in Kiwisaver. One way of keeping these contributions and regaining the support of business would be for National to allow wage cuts on the basis of entry into Kiwisaver (with its compulsory employer contribution). The Standard laments such a move, however there are two reasons why I don’t think it’s a big deal:

  1. In most cases such a policy won’t change anything,
  2. In this cases where the policy leads to lower wages it may actually be “fairer”

Let me explain myself:

OCR review preview – June 2008

Well we have had an action packed quarter haven’t we – bad employment numbers, bad retail numbers, bad inflation numbers, and tax cuts.

Of course I’ve stated that all these things imply more inflation, but its not what I think thats important – its what the Reserve Bank thinks that matters. On June 5th we get to here what there outlook for economic activity really is – and as a result we will get an idea about how their view of future monetary policy easing has changed (from September 2009 as a starting point in March).

So what is going to happen? The Reserve Bank will heavily reduce their growth forecasts (I’m guessing 0.9% growth over the March 2009 year – with a technical recession over the first half of 2008). A weaker labour market outlook and a downturn in global growth forecasts will be major factors behind this shift – along with a sharper housing market correction. The delay of the ETS will lighten up inflation forecasts while additional fiscal stimulus will lift it again – fundamentally inflation will cross 4% in September, but head under 3% by June.

It is possible they may state that fiscal policy changes (ETS and tax cuts) cancel out – especially given that most of the tax cuts appear out in 2010 – and approximately 50% of consumers are supposed to act in a manner that is “liquidity constrained” (so will not borrow on the tax cuts which are coming).

With inflation expectations elevated and the dollar threatening to bolt with three months of potential rate cuts the Reserve Bank will probably implicitly time rate cuts from March 2009 in the MPS – however with some (real) risk of cuts occurring earlier.

Personally, I think inflation pressures are far more endemic – but I believe that the Bank believes that the risks to growth are too strong to ignore. If this is the way things go down I would expect a short rally in the dollar – before the realisation that the RBNZ was just treading water sets in, dragging the dollar back to where it started.

Collusion, multiple equilibrium, and petrol prices

Conjecture is rife regarding why petrol prices have risen so strongly. There are a number of common explanations:

  1. Rising demand for oil,
  2. The weak US dollar, increasing the US$ price,
  3. Peak Oil (Infometrics article requires a subscription),
  4. Negative real interest rates in the US (as not mining the oil is the same as investing in inventories),
  5. and speculation.

All these factors are playing a part in the saga of ever rising oil prices. However, Calculated Risk has suggested another, highly interesting way that fuel prices could have risen – a backward bending supply curve and multiple equilibrium.

This idea is pretty cool – so I thought I would spend a little bit of time explaining how it could work.

What is this savings problem?

So far we have discussed Kiwisaver and national savings in fairly loose terms. We know that (part of) the purpose of Kiwisaver was to increase national savings and that our interest in national savings stems from the fact that we want New Zealand to have more productive capital.

So before we can discuss the myriad of burning questions surrounding these issues – and more broadly surrounding New Zealand’s productivity (such as if Kiwisaver achieves the greater capital goal even if it theoretically doesn’t increase savings) we need to ask, what is the savings problem?
