Liberalization policy, production and cost efficiency in Taiwan’s telecommunications industry

Many economists, policy-makers, and corporate managers have long believed that the operational performance of private enterprises is much more efficient than that of public utilities. However, some researches on changes in efficiency before and after privatization contradict this. The purpose of this paper is to analyze changes in technical and cost efficiency in Chunghwa Telecom Company (CHT) before and after partial privatization.The input-orientation Data Envelopment Analysis (DEA) and Cost-DEA were the research tools used in this study, and the findings showed that the technical efficiency, allocation efficiency, and cost efficiency become worse after partial privatization. Additionally, we found that CHT cannot achieve any significant improvement in cost management under its partial privatization environment. CHT is still restricted by government policies and regulations, thus undermining its ability to achieve any significant improvement in its cost management. In order to improve efficiency for CHT, the government needs to eliminate some regulations and relax its control over CHT, thus creating a completely privatized environment.

A methodology to select the experimental plant instrumentation based on an a priori analysis of measurement errors and instrumentation cost

An experimental apparatus for evaluating carbon dioxide local heat transfer coefficients during flow boiling has been set up at University of Naples Federico II. In this paper, the local heat transfer coefficient measured is evaluated relative to the measurement error, varying the type and costs of the instrumentation. The analytical analysis has been performed prior to construction of the test facility. The main aim of the work is to provide a methodology that allows one to reach the best compromise between measurement accuracy and financial resources in the selection of the instrumentation.
