If a firm with two large plants installs a large, custom built assembly line in each of its plants, the custom assembly line is an example of ________.

Suppose there are only two goods – Food (F) and Shelter (S). The demand equations for these two goods depend on their prices, pF and pS as follows:

DF (pF, pS) = 10 – 2pF – pS DS (pF, pS) = 10 – pF – 2pS The supply curves depend only on their own prices: SF (pF) = pF SS (pS) = 5pS Determine the equilibrium price and quantity of these goods.

In the derivation of TFC, you find
