• Drawing on the author's previous case study on the publicly operated AT & T in the U. S. reported in the University Journal, No. 9., this analysis presents a case study of the econometric planning model of the Canadian telecommunications industry headed by Bell Canada. This paper consists of eight sections. In section I, we review the econometric modeling efforts of the public corporation in the past and evaluate its current status and future prospect. This introductory section is followed by section II, which highlights the institutional features of public enterprises in Canada. Particularly noteworthy is the fact that there are the third firms like Bell Canada, neither government-sponsored firms and subsidiaries nor foreign firms among the large size firms in Canada. Section III is devoted to the setting-up of the model and describes the ownership structure of the network, the structure of ownership and control, and the regulating agencies in the telecommunications industry with special attention to price regulation. Examining the specification of the demand model contained in the DTWLC model developed by Dobell et al., section IV identifies that such demand model is nothing but an application of the Houthakker-Taylor model. In addition, the data sources of aggregate as well as disaggregated data for the Canadian telecommunication, which are of critical importance for our empirical study, are carefully scrutinized. Section V reports on the estimation of results for all Canada based on the DBS data. The demand functions are evaluated separately for the total revenue, and for the local and the long service revenues. Then, elasticity analysis is also attempted. Section VI summarizes the results of the regional study based on the pooling of DBS data for the four regions. Section VII utilizes the data of Bell Canada in order to estimate the demand functions for telecommunications submarket in Canada for different uses. The estimated function pertain to residence local-service revenues, residence long-distance revenues, total residence revenue, business local-service revenues, business long-distance revenues, and lastly, the total business revenue of Bell Canada. Section VIII concludes the paper as follows: (1)the demand for telephone services is influenced by habit formation; (2)the income elasticity of demand in the long run favorably exceeds unity; (3)demands for local service by residential and business uses and for the long-distance service by business use are independent of the relative price structures; (4)the demand for long-distance services by residential use is largely determined by the long-run price elasticity of demand; (5)demands for telephone services are not structurally different by region, which justifies the homogeneous regional aggregation.
