Comments on: Carbon cost of cities http://www.tvhe.co.nz/2009/03/12/carbon-cost-of-cities/ The Visible Hand in Economics Sat, 03 Sep 2022 20:58:37 +0000 hourly 1 https://wordpress.org/?v=6.9.4 By: Matt Nolan http://www.tvhe.co.nz/2009/03/12/carbon-cost-of-cities/#comment-17962 Thu, 12 Mar 2009 00:07:18 +0000 http://www.tvhe.co.nz/?p=3186#comment-17962 I get that rauparaha – but in the post you just said that the impact could be non-linear. Now, I assumed that you were saying non-linear in concentration – but since you didn’t say that I was wondering if you actually had other types of non-linearities in mind as well.

When I read the paragraph I felt it went: example + statement. The statement was more general than the example – so I was wondering if there was some other examples you had in mind when making that statement.

I just meant that, if the environmental damage function is non-linear in concentration, then total damage isn’t necessarily lower when you decrease emissions but concentrate them more.

The only thing I could think of was concentration – and I was just wondering if you had any other hip idea in mind

If the effects of pollutants are non-linear then the environmental cost of cities may still be higher”

Sorry I’m not sure what you are saying. Are you saying that the location of the emissions also matters – not just the per capita size of emissions?

The way I see it the author is putting forward two extreme examples – put everyone in a city, or spread everyone over the country. If we put everyone over the city total emissions will be lower (although as you state there are indirect issues that aren’t addressed!). However, the location of these emissions is more concentrated.

Are you saying the concentration matters in the above quote – or is there something else at work here?
