An examination of the equilibrium specification and structure of production for Canadian telecommunications
估计了加拿大电信业的多产出生产模型，检验了短期与长期均衡，发现长期均衡被拒绝；进一步估计了贝尔公司的动态调整成本模型，发现每1美元边际资本成本需额外支付0.30美元安装成本。
Abstract Multiple‐output models of Canadian telecommunications production are estimated under different production equilibria. A specification test is conducted between the short‐ and long‐run equilibrium models and the long‐run equilibrium is rejected. In order to capture the nature of the disequilibrium, a dynamic cost of adjustment model is estimated for Bell Canada. There are significant adjustment costs and it is estimated that for $1.00 of marginal capital costs the carrier must incur an additional cost of $0.30 to install the new capital into the production process.
