On the performance of endogenous access pricing

Endogenous access pricing (ENAP) is an alternative to the traditional procedure of setting a fixed access price that reflects the regulator’s estimate of the supplier’s average cost of providing access. Under ENAP, the access price reflects the supplier’s actual average cost of providing access, which varies with realized industry output. We show that in addition to eliminating the need to estimate industry output accurately and avoiding a divergence between upstream revenues and costs, ENAP can enhance the incentive of a vertically integrated producer to minimize its upstream operating cost. However, ENAP can sometimes discourage surplus-enhancing investment. Copyright Springer Science+Business Media New York 2013
