A forward-looking analysis of residential telephone access demand in Korea

Abstract

This paper analyzes the price elasticity for residential access demand in Korea using survey data of 1998. We apply an asymmetric GEV model to this data and derive a formula for forward-looking price elasticities of the penetration rate. We categorize the respondents into two groups, single-line households and multi-line households, and estimate the price elasticities for each group. Estimation outcome shows that single-line households are less sensitive to price changes than multi-line households with respect to installation charge and rental charge. In view of the relatively low price elasticities of single-line households, an increase in rental charge is not expected to result in large-scale drop-offs of primary lines.
