Comments on: What is up with petrol prices? http://www.tvhe.co.nz/2009/02/13/what-is-up-with-petrol-prices/ The Visible Hand in Economics Mon, 16 Feb 2009 19:03:28 +0000 hourly 1 https://wordpress.org/?v=6.9.4 By: Matt Nolan http://www.tvhe.co.nz/2009/02/13/what-is-up-with-petrol-prices/#comment-14693 Mon, 16 Feb 2009 19:03:28 +0000 http://www.tvhe.co.nz/?p=2869#comment-14693 Hi Bernard,

Thanks for the graph. I have seen these figures on margins before – and I noticed that they were tightening through January – but they now appear to have returned to about average. This is the key issue against my view of tacit collusion.

I was wondering if anyone knew what is happening to refining costs – I have heard rumours that this is where the heat is coming on petrol prices.

Thanks for that – I’ll link to it in the post.

Search will definitely be part of the issue. I think tacit collusion also plays a role – there is nothing wrong with that in itself either, as I’m not sure that prices would be stable up there in the long-run.
