Abstract: | This article describes how Japanese residential customers choose among long-distance carriers. Based upon a 1993 survey, the model indicates that the time required to register customers, whether extra digits are required to use a carrier, and whether a carrier can provide both local and long-distance calls, as well as the carrier's brand identity are significant service attributes that affect competitive outcomes. The effects of these services differences are quantified. Simulations are used to illustrate the competitive impacts of reducing service differences among carriers. |
