- ItemTHE DEFENSE OF PRICE DISCRIMINATION IN NETWORK AND INFORMATION GOODS MARKETS(Technická Univerzita v Liberci, ) Soukal, Ivan; Ekonomická fakultaIt is not uncommon that articles focused on consumer-price interaction in the network and information goods market swiftly condemn price discrimination as an obfuscation, on-purpose price complexity, or market failure. The reason is a general neoclassical rule of an efficient market where prices are set at marginal cost with no price discrimination. However, the matter is more complicated. This review provides authors an overview of why, where, and which type of price discrimination should be viewed by different optics. Goods such as software, cell carrier services, electronic newspapers subscription, electric energy supply, payment accounts, books, copyrighted content streaming, etc, cannot be treated like manufactured goods. The reasons are specific conditions – substantial and/or repeated fixed/sunk cost, economies of scale, and demand heterogeneity. Recognized economist W. J. Baumol described marginal cost set prices under these conditions as an ‘economic suicide’. Reviewed articles showed that firms are forced to adopt price discrimination in order to recover their costs and to serve more consumer segments. Reviewed authors provided facts to support the use of multipart tariffs, dynamic pricing, versioning, bundling, and Ramsey pricing. These conclusions are used for suggestions on how several studies of information and network goods should be modified. Modifications are related mostly to model assumptions and pricing conclusions. I argue that, in the case of information and network goods, there is justified price discrimination. Hence, there is a certain justified level of price complexity that has to be accepted and not taken as automated evidence of inefficiency, market power, and consumer exploitation.
- ItemHow Does a Retail Payment Account Consumer Changes over Time? Usage Rate Behavioral Segmentation from 2010 till 2016 in the Czech Republic(Technická Univerzita v Liberci, ) Soukal, Ivan; Draessler, Jan; Ekonomická fakultaThe paper is focused on retail payment account consumers with account access via e-banking. Firstly, the goal is to provide payment account usage profiles at the level of payment instruments. Secondly, to assess the development of identified profiles during the crisis and post-crisis year 2010-2016 in the Czech Republic. The two-step cluster analysis sample segmented 16,392 individual payment account usage records. Three clusters were identified: price-driven, active, and low balance/overdraft user. The clusters were mainly separated by an ATM usage and average balance. Payment instruments showed a less significant difference. The first cluster showed exclusive preference of own bank’s ATM network. The second cluster manifested the highest usage frequencies and the broadest range of services. The third cluster had average account balance below zero with most of the consumers declaring an average balance from €-925 to €370. A steady trend of change was found regarding the demand structure. The price-driven profile was a mainstream consumer segment till 2014. The active consumer segment became dominant in 2015 due to a steady trend of price-driven profile share loss. The third cluster’s share remained stable over the surveyed period. The next change in consumer typology was related to the usage rate. All clusters showed an increase in ATM usage over time. Price-driven cluster steadily increased ATM withdrawal abroad from technical zero to 0.4 per month. Active profile and low balance/overdraft user increased domestic ATM usage by almost one withdrawal per month. Direct payments showed an increase over time as well. Direct payments shared trend of increase in average by one payment per month, in a case of the price-driven profile by two.
