    Determining spectrum caps and service efficiency: A case study of mobile operators in Thailand

    Mobile spectrum is a crucial natural resource, which is essential in a nation's economic growth and a mobile operator's business operations and sustainability. Moreover, spectrum auctions have become a common method for spectrum allocation by telecom regulators in recent decades. In Thailand, the National Broadcasting and Telecommunications Commission (NBTC) over the past years has used a spectrum cap setting mechanism to encourage more competition in both the auctions and in the market after the auctions. This mechanism also allows regulators to determine the number of mobile operators in the market. However, regulatory mandated spectrum caps can potentially harm a large mobile operator's performance since spectrum caps can preclude large carriers from getting more necessary spectrum to support their customers' demand. Therefore, the purpose of this research was to demonstrate the effect of spectrum caps' determination using frequency allocation in Thailand as a case study. This paper employs data from Q3 2012 - Q1 2020 for the three major mobile operators in Thailand (AIS, TRUE, and DTAC) and analyzes the mean difference of six operating parameters by 1 MHz spectrum and the industry average. Results revealed that AIS was the largest carrier with the most spectrum amount, the greatest number of users, with revenue exceeding the industry average. AIS also had a statistically significant operational efficiency in all six of the evaluated dimensions. However, TRUE which is second in the total number of users in Thailand was determined to have no statistically significant operating efficiencies. Furthermore, the study determined that operators need additional spectrum so that they can increase market share through improved service quality. Finally, the empirical evidence suggests that spectrum caps when set in conjunction with each auction did not create any significant operator's efficiency problem.

    Purpose: The aim of this paper is to explore the price plans offered by Thai mobile operators and analyse the role of demand characteristics in the development of new price plans. The paper also shows how demand affects a firm's degree of innovativeness in terms of the number of new price plans. Design/methodology/approach: The empirical qualitative analysis is based on an original data set from several secondary data sources and includes all the price plans offered in the history of the Thai mobile communications market between 2002 and 2010. Findings: The results show that mobile operators have introduced several innovative price plans to attract and retain their consumers. Although a greater number of price plans can increase competition among operators, some have complex combinations that may lead to confusion for consumers. Practical implications: A price comparison programme should therefore be implemented by the telecom regulator to ensure that consumers receive correct and complete information about the price plans. Originality/value: Most studies, by far, have not extensively discussed this mobile communications market in detail and the effect of innovation on competition between firms in the mobile communications industry, in particular the development of innovation in developing countries. © Emerald Group Publishing Limited.
