As I understand it, the term 'flat-earth economist' refers to an economist who ignores physical resource constraints. To quote
"Oil Based Prospects for the Future",who are in turn quoting John Mitchell et al.,
$this->bbcode_second_pass_quote('Danish Scientists', 'T')hey argue that reserves are not fixed but determined by
$this->bbcode_second_pass_quote('John Mitchell et al', '')the mix of knowledge, technology and investment that sustains the process of exploration and production sufficiently to meet short- and medium-term demand expectations. Reserves depend on the interaction of this process, government policies and, finally, the price people are willing to pay for oil products. Since we cannot know future technology or prices, we cannot quantify future reserves. This should not be a concern, since it is these processes that are important. Ultimately, as [Morris A.] Adelman commented, ‘oil resources are unknown, unknowable and unimportant’"
It is important to remember
why anyone would ever believe this, and in which domains this belief is still useful today.
When mining for other resources, such as copper, for example, in the past, you might only have mined an ore if it contained, say, 30% copper. As 30% copper ore sites were used up, price would gently creep up, making 29% ore worth mining. If this get's short, then, in turn, 28% copper becomes worth mining. Economists have watched as the economically minable concentrations of ore, which were once for some metals at 50% or higher, have gradually fallen to below 1%. In almost all normal instances for mined metals, the resource base has gradually increased through time as a function of "knowledge, technology, and investment".
Oil is a special case. Well not really. It's just not a handy metal - it's an
energy source. I think the real mistake is to class oil with other 'mined things', as if it were a precious metal. Oil should properly be analysed as an energy source. That wont sound like anything interesting to people reading this here. It is obvious. But I suspect, however, that for the average economist who passes by, it might be a particularly easy mistake to categorise oil as 'dug up by miners', with copper, tin, lead, zinc etc. as far as economic analysis is concerned. As Colin Campbell explains (in the Dane report above), even coal functions a lot like the precious metals as far as resource expansion goes...
$this->bbcode_second_pass_quote('Colin Campbell', 'A') coal deposit covers a wide area having huge ‘resources’ but only at places with thick seams or ease of access do the ‘resources’ become ‘reserves’ to be mined. It is largely a matter of concentration. Thus, if prices rise or costs fall then lower concentrations become viable ‘reserves’. It is the same with mineral mining.
Oil is different because it is a liquid which collected in certain places. It is either there in profitable abundance or it is not there at all. The oil-water
contact in the reservoir is abrupt. So it is not a matter of concentration. The notion of huge ‘resources’ being converted to ‘reserves’ as needed is deeply embedded in economic thinking, but it does not apply to conventional oil. But, of course, the tar sands behave like coal.
If we can understand how the error is made, we can help to correct it. So long as peak oil activists do not address the mistakes implicitly made by detractors, it will not go mainstream.
