The Voyager 2 spacecraft has just passed through the heliopause and into interstellar space, forty years after it was launched. On the one hand that’s a stunning technological achievement and a reminder of the wonderful universe we live in. On the other, it’s a reminder that humans will never go out to explore this universe, or even leave Earth in significant numbers. Although Voyager 2 has passed the heliopause it is still within the gravitational field of the sun. It would take...

The market price of Bitcoin and other cryptocurrencies is plummeting, having dropped by 10 per cent just today, and 50 per cent over the past month. The bubble that reached maximum expansion a year ago is gradually deflating. The good news is that a lower Bitcoin price makes the energy-wasting process of Bitcoin mining unprofitable for many, so lots of miners are turning off their servers.  Most estimates of the marginal cost of mining are around $4500 per coin, but the market price has...

This story about the four-hour abalone fishing season in WA is reminiscent of a number of similar cases discussed in my soon-to-be-published book, Economics in Two Lessons (extract over the fold). However, it turns out to be something of a special case: a recreational fishery where economising on effort isn’t really relevant, and where the activity is culturally significant, mainly for people of Asian background. In these circumstances, a short season, with open access, makes good...

Carbon dioxide emissions rose strongly last year after several years of a near plateau. It appears that the main factor was increased use of oil, mainly as motor fuel. I’ll try to do a more detailed analysis later, but the central element of the required response is obvious. Just like coal-fired power stations, petrol-driven motor cars need to be phased out, as quickly as possible. Australia, as an oil importer with no domestic car production is in a position to pursue this target...

A week ago, I was speaking at a Royal Society of NSW Forum on the topic “Getting climate policy back on track” when the news came through that Adani had announced a start to the Carmichael mine “before Christmas”, funded from the company’s own reserves.  With Christmas now less than three weeks away, where do things stand? It’s evident that, as with previous construction starts, this one won’t be on a large scale. Adani has just posted its first job opening for a year, on the portal it...

The long-running Brexit fiasco has overshadowed most news coming out of the United Kingdom these days. It’s not surprising, therefore, that hardly any attention was paid to news that may be of more long-term economic significance to Australia, and to the current crisis of neoliberalism, than a rearrangement of relations between the UK and the European Union. In the Budget brought down in late October, UK Chancellor of the Exchequer, Phillip Hammond announced the end of the Public...

Adani Mining announced today that its scaled-down Carmichael mine project would proceed without any external funding. Before considering reactions, it’s important to recall causes for scepticism. First, Adani has repeatedly announced the imminent start of the project, while doing little or nothing. It is possible that this announcement will be followed by months, or even years, of “pre-construction activity” during which the project is kept alive with minimal expenditure from Adani....
