Estimation of Price Elasticities for an International Telephone Demand Model
针对澳大利亚国际电话的三种服务，构建了一个包含两个子模型的计量经济模型，分别估计总通话次数在三类服务间的分配以及总通话时长在直拨和人工转接服务间的分配，从而计算价格弹性。
The demand for international telephone calls in Australia is comprised of three s ervices with three distinct prices. In order to estimate elasticities for both tariffs and surcharges, an econometric model is developed t hat has two submodels, each of which consists of an aggregate equatio n and an allocation system. One model determines how the total number of telephone calls is allocated among the three services, while the second allocates the total number of minutes called between directly- dialed and operator-connected services. The model is estimated using aggregate data for telephone traffic emanating from Australia. Copyright 1988 by Blackwell Publishing Ltd.
