This paper examines demand for international telephone services. Using panel data covering 57 routes over 6 years, a model featuring a two-stage budgeting process and product differentiation is implemented for empirical estimation. A range of economic, social, cultural and technological variables are included in the aggregate-level model to study overall demand. The unique and rich data offers an opportunity to examine the impact of new technology innovations such as Internet on traditional telephone services. The company-level model incorporates product differentiation and uses the Almost Ideal Demand System to simultaneously estimate demands for and competition between carriers.
