The Bessemer Process
Borrowing money becomes more expensive and there is less investment in production.

Assuming you mean price of supplies: Finding ways to optimize the processes and making production more efficient and less costly. Or the good old staff lay offs.
A point inside a production possibilities curve represents things that can be produced. However, points inside the curve would be less efficient to produce than those points resting directly on the line.

Cheaper labor and less restrictive production standards .
The aluminum door is lighter and less expensive than steel door.
Steel. It's a much stronger and much less expensive material.
The least expensive mode of transportation is by water. It is fuel efficient, less polluting and the safest. It is also the least expensive to move cargo.
It depends on the applications. Stainless Steel is more corrosion resistant and more expensive. Carbon Steel is cheaper and less corrosion resistant.
They are not necessarily superior. Mag-Lev trains "sway" above the track and therefore they have no friction with anything other than air. Their energy consumption is less efficient and because of the massive concrete or steel track slabs junctions and other track elements are much less efficient and more expensive the traditional rail guided trains.
Some of it was made of steel, some parts were iron, which was less expensive than steel, and certain parts were bronze which was more expensive than steel, but superior in several respects, such as that it does not rust. The armor also have had important parts made of leather, to which the steel was attached.
It depends largely on what it's a kilo of--a kilo of brick dust is much less expensive than a kilo of steel, which is less expensive than a kilo of uranium.
