Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
That's the autistic version which doesn't accept the existence of the outside world.

A more realistic model accepts that natural resources drive the rest of the economy. And being finite, when the natural resources run out, the economy simply stops working.

y(t) = f(A(t), C, -L) * (R-(g(t))

(L is negative because it's considered a drain on output.)

In fact y(t) feeds back to C via a financialisation multiplier, because capital/debt is considered (spuriously) as the engine that drives the economy and/or the brake that prevents it working.

Even more accurately, as R-(g(t)) tends to zero, C decreases because extraction costs eat into profit.

Putting it all together you get something like

y(t+1) = f(A(t), k*y(t), -L) * (R-g(t))

A lot of economics seem to obsessed with k's irrational gyrations, when it's the other terms that define historical outcomes over long periods.
