%A Angel Lopez %A Patrick Rey %J Journal of Industrial Economics %T Foreclosing Competition through Access Charges and Price Discrimination %X This article analyzes competition between two asymmetric networks, an incumbent and a new entrant. Networks compete in non-linear tarifs and may charge different prices for on-net and off-net calls. When access charges are high, this allows the incumbent to foreclose the market in a profitable way if switching costs are sufficiently large. In the absence of termination-based price discrimination, however, such foreclosure strategies are not profitable. %N n° 3 %P 436-465 %V vol. 64 %D 2016 %I Blackwell %R 10.1111/joie.12115 %L publications16873
