On labor? Much cheaper. And labor is typically the greatest cost.
In First World countries, sure. In Third World countries, maybe not so much.
A lot would depend on whether there was a local concrete industry.
Edit: I'm not so sure that this is all that "eco-friendly" either -- cement production requires a lot of energy.
That said, concrete is very durable (if made and poured properly) and might be a win in the long term.
