The shape of LRAC is due to the law of returns to scale. The law of diminishing returns is applicable in short run.

Which of the following is NOT an example of a fixed cost?

Answer

d. wages paid to workers

Wages paid to workers is a variable cost. It varies according to the change in output.

In a perfectly competitive industry we expect that a rightward shift in the industry supply curve will cause:

When the supply curve shifts to right hand side, there will be an increase in supply being the demand remains constant. The price will come down and supply or output increases.
