I have no recollection or record of saying this,
and economic models are most certainly "non-linear".

I make the same claim as Prof. Krugman, so I don't see
him as coy or deceptive. And bionomics seems squarely
marketed as a substitute for mainstream economics, not
Keynes and Marx.

talking heads you see.

Romer's work is solidly within the standard
"equilibrium thinking" framework. (In economics,
equilibrium doesn't mean statis.)
