The case for a consumption-based carbon tax

March 3, 2019 - 19:12 -- Admin

Coal is Australia’s second largest export – over 10% of total exports. These will not end soon and the coal lobby is a politically powerful obstruction to taking measures to effectively address climate change. The suggestion by Geoff Carmody – one I have also long endorsed and written about – is to impose a destination-based carbon tax which exempts all coal exports but which taxes coal consumption locally as well as all other forms of carbon pollution locally.

Black-throated finches to possibly stop Adani

Not completely sure of the conservation logic here but it will be a good outcome if it occurs. I photographed these Black-throated finches inland from Port Douglas last year – specifically about 20 klm west of Mount Carbine. It is the second time I have seen them there. It is near a dam site on a cattle property. Great spot – we also saw Great bowerbirds and some Comb-crested jacana. The following photos are an embed from my FB page:

Arguments for eco-centrism & deep ecology: draft subject to revision

January 6, 2019 - 19:09 -- Admin

The conventional view of economists and others is that nature and biodiversity have instrumental value as a consumption good (broadly defined to include conservation, aesthetic and altruistic motives as well as standard uses) and as a factor of production (e.g. transport or dairy. Thus we stop species from going extinct because it offends the convexity of our preferences – humans value diversity.

Fish wars

It is important to understand the basic economics of conflicts over fishing rights as discussed in this article.  The problem arises from the difficulty or impossibility of enforcing property rights over access to fishing rights.   With open access exploitation of fisheries – a free for all grab for available fish – there is excessive exploitation of fish  and total fish yields decline.  It is impo

Driverless car technology and congestion

November 2, 2018 - 09:37 -- Admin

A traffic engineer told me the other day that driverless car technology would largely replace the need for expanding road systems in urban centers.   The general idea is that if car travel can be automated that there are plenty of roads for cars to make synchronized journeys on so congestion will disappear.  There are now many studies that question the claim that driverless cars will reduce congestion – t

Comments on corporate taxes

Most people don’t seem to understand* what company tax is intended to do in Australia’s tax imputation system. The idea of imputation is to avoid taxing the same income twice. When a firm earns profits it is taxed on those profits at the company tax rate of 30%. If some of the after-tax profits are distributed as dividends to shareholders then the intention is not to tax this income a second time when it reaches the shareholder.

Investment advice

February 26, 2018 - 13:12 -- Admin

I am often asked to give financial advice to friends and colleagues partly on the grounds that I am an economist and partly because, it is supposed, I have a fair bit of experience in investing. My response is that I have no special expertise in making investment choices although I do have strong views on what should be avoided.
