Our study focuses on the identification and the measurement of switching costs and network effects in mobile telecommunications. Although these two phenomena create similar consumer lock-in mechanisms, there are no empirical studies that integrate them into one model of subscriber’s behavior....

In this paper we utilize discrete choice experiment method to identify and measure switching costs and network effects in mobile telephony in Poland. Based on hypothetical choices consumers make we construct a conditional random parameters multinomial logit model to analyze their preferences. In...

This paper probes the phenomenon of delayed cable digitization in countries such as Korea and Taiwan. The paper first performed a cross-country longitudinal analysis on the 16 countries in the Asia Pacific region and found out that 1. inter-platform competition, primarily from DBS, generates the...

We analyze market dynamics under Bertrand duopoly competition in industries with network effects and consumer switching costs. Consumers form installed bases, repeatedly buy the products, and differ with respect to their switching costs. Depending on the ratio of switching costs to network...

This thesis addresses theoretical and empirical questions related to network economics. In particular, it analyze network effects and switching costs in the mobile telecommunications industry. The first chapter analyzes competition in a two-period differentiated-products duopoly in the presence...

Switching costs and network effects bind customers to vendors if products are incompatible, locking customers or even markets in to early choices. Lock-in hinders customers from changing suppliers in response to (predictable or unpredictable) changes in efficiency, and gives vendors lucrative ex...

We study oligopoly price competition between multiproduct firms---firms whose products interact in the profit function. Specifically, we focus on the impact of intrafirm product interactions on the level of equilibrium profits. This impact may be decomposed in two different ways: (a) a direct...

We analyze Bertrand duopoly competition in markets with network effects and consumer switching costs. Depending on the ratio of switching costs to network effects, our modelerates four different market patterns: monopolization and market sharing which can be either monotone or alternating. A...
