Question: 7.2.5

A firm builds wooden shipping crates. How does the cost of producing a 1-cubic-foot crate (each side is 1 foot square) compare to the cost of building an 8-cubic-foot crate if wood costs $1 per square foot and the firm has no labor or other costs? More generally,how does cost vary with volume?

Verified Answer:

The total cost of building a 1-cubic-foot crate is...

Question: 7.6

A firm has a Cobb-Douglas production function that is homogeneous of degree one: q = AL^aK^(1 – a). Derive the firm’s long-run cost function as a function of only output and factor prices. What is the cost function that corresponds to the estimated beer manufacturer’s production function
