Estimating economies of scope using the profit function: A dual approach for the normalized quadratic profit function

  • Gao, Zhifeng
  • Featherstone, Allen M.

Theoretical relationships between parameters of the normalized quadratic profit and cost functions are derived allowing for economies of scope to be calculated using profit function estimates. An empirical example confirms that the cost function is recovered using the estimated profit function.
