Think of it this way, is a 4 carat diamond only double the price of a 2
carat diamond? The bigger it is, the more it costs and the increase in
price is a curve, not linear.

But that's assuming larger sizes are rarer. In the case of lumber,
shouldn't thicker boards require FEWER cuts, and therefore be cheaper
per bf? To a certain extent, of course - I understand that super wide
stuff is rare. I also understand that lumber prices vary a great deal
by location, but I don't know how that would affect 8/4 vs. 4/4
pricing.
Really I don't know much about lumber pricing and wood product
economics, just tossing out my ideas.


Nor do I, but time is money. And it takes (a lot) more time to grow thicker
trees. If you cut thick lumber from smaller trees, you're going to get more
instability in the resulting lumber.
