Analysis of consumer preferences for mobile telecom plans using a discrete choice experiment

In this paper, we present a study of consumer preferences for mobile telecommunications plans and operator characteristics. The objective of the study was to identify consumer preferences for the following characteristics of mobile plans: the importance of using the same provider as friends and family (calling club network effects), the market share of the provider (pure network effects), the length of the commitment period, monthly fee/recharge obligations and per minute call charges for calls made within and outside the provider network. A discrete choice experiment was used as a preference elicitation method and implemented in face-to-face interviews. We present results regarding willingness to pay for the described features as well as their relationship to socio-demographic variables. Consumers are willing to pay 1.3 Euro per month more to reduce the commitment period from 1 year to 6 months and willing to pay 2.5 euros per month more to be part of a larger network. Consumers are also twice as much more sensitive to within-network price variations than extra-network price variations. These results remain unchanged in the sub-sample of those that have internet access suggesting that a web-based surveys are capable of producing unbiased results. The implications of these results for regulatory policy are discussed.     

Financial distress,survival network design strategies,and airline pricing: An event study of a merger between a bankrupt FSC and an LCC in Brazil

This paper develops an event study to investigate the airfare effects of the bankruptcy of a financially distressed full-service carrier (FSC) and its subsequent acquisition by a low-cost carrier (LCC) in Brazil. We account for the distressed carrier's survival network design strategies (SNDS) pursued during its reorganization—a suspected source of sample selection bias. Additionally, as rivals' pricing could be aimed at driving the distressed/bankrupt carrier out of the market, we treat the carrier's distress as endogenously determined with it. Our results do not uncover any survival pricing behavior stemming from SNDS, but reveal fiercer price competition from rivals in periods preceding both the distressed carrier's bankruptcy filing and acquisition. We also find evidence of enduring price competitiveness in the long run of the acquisition event, shedding light on the potential facilitating role played by bankruptcy protection regulations in keeping and sustaining market contestability after the bankruptcy-filing period.     

The transformation of a legacy carrier – A case study of Turkish Airlines

This study examines the metronomic rise of Turkish Airlines into a global carrier in the period following domestic deregulation and part privatisation. Using a comparative assessment of the carrier's network and its competitive strategies during the 2003–2013/2014 period it was found that Turkish Airlines now benefits from considerable network, cost, service and brand advantages over competing European and to a lesser extent Middle-Eastern airlines. Its network operation based in Istanbul Ataturk airport enjoys strong geographic and demographic advantages, which enables it to optimise the use of its large and young short-haul fleet between a significant number of domestic and international points. This study has important implications for partially or fully state owned legacy carriers as to how to gain competitive advantages in an increasingly open and liberal airline industry.     

转换成本、网络规模与信用卡产业竞争策略比较

近年来，我国信用卡产业呈现出市场集中度逐年下降的趋势。信用卡市场的竞争融合了网络效应、兼容性及转换成本等因素，而在兼容性一定的环境下，不同银行的竞争策略往往不同。本文通过防降价均衡模型估计出2010—2012年我国九家上市银行的信用卡转换成本，并对网络规模扩张、转换成本定位以及竞争成效等进行分组比较。结果表明，股份制商业银行利用较低的转换成本吸引新客户，实现了更高的业务规模增长率；四大国有商业银行则利用高转换成本锁定其已有客户，并以高速扩张网络规模来竞争新客户，使其同股份制商业银行的业务规模增长率差异逐年下降。这说明网络产业中不同市场地位的厂商可将转换成本定位与网络规模扩张作为差异化策略，以此实现竞争优势。     

Independent directors’ board networks and controlling shareholders’ tunneling behavior

As one of the channels by which board directors build important relationships, board networks can affect the governance role of independent directors. Defining director board networks as their connections based on direct ties they establish when serving on at least one common board, this paper explores the role of the network centrality of independent directors in restraining tunneling behavior by controlling shareholders in the Chinese capital market. Our empirical evidence shows that tunneling behavior by controlling shareholders is negatively related to the network centrality of independent directors and that this relationship is stronger when non-operating fund occupation is used as the measure of tunneling. The results of our study show that board networks can help independent directors to restrain tunneling behavior by large shareholders, which plays a positive role in corporate governance.     

Competing in network markets: Can the winner take all?

Products as varied as software, credit cards, and even coffee makers are influenced by network effects whereby the product's value is contingent upon the number of people using it. In turn, markets for these products offer lucrative returns to managers who can leverage the dynamics in their favor. This article describes recent research focusing on the factors that influence success and failure in network markets. We offer recommendations and initiatives that increase the likelihood of success in network markets for entrepreneurs and incumbents alike.

The Effect of Market Transparency: Volatility and Liquidity in the Korean Stock Market

Faced with unprecedented competition, stock markets should have fairness and transparency. The effects of market transparency for the stock market volatility and liquidity will be investigated using the case of the Korean stock market. The evidence from this study indicates that increasing the market transparency makes the price discovery process more efficient than before from the viewpoint of stock market volatility, and increases the stock market liquidity compared with before.
