Competition and Price Dispersion in International Long Distance Calling

This paper examines the relationship between changes in telecommunications provider competition on international long distance routes and changes in prices on those routes. Overall, increased competition is associated with significantly lower prices to consumers of long distance services. However, the relationship between competition and price varies according to the type of long distance plan considered. For the international flagship plans frequently selected by more priceconscious consumers of international long distance, increased competition on a route is associated with lower prices. In contrast, for the basic international plans that are the default selection for consumers, increased competition on a route is actually associated with higher prices. Thus, somewhat surprisingly, price dispersion appears to increase as competition increases.
