Ode to economics

Oh buffer stock, buffer stock
where do you go?
Cobwebs to you, you basket
of representative goods
WHy does the demand curve?
I don't think it should.

I'm almost at my short run
close down point
My marginal product
is subject to diminishing returns
My supply curve
has shifted way off to the left
and I think I'm a vegetable market
in perfect competition with my brain.
