Tariff-Specific Preferences and Their Influence on Price Sensitivity

For many services, consumers can choose among a range of optional tariffs that differ in their access and usage prices. Recent studies indicate that tariff-specific preferences may lead consumers to choose a tariff that does not minimize their expected billing rate. This study analyzes how tariff-specific preferences influence the responsiveness of consumers’ usage and tariff choice to changes in price. We show that consumer heterogeneity in tariff-specific preferences leads to heterogeneity in their sensitivity to price changes. Specifically, consumers with tariff-specific preferences are less sensitive to price increases of their preferred tariff than other consumers. Our results provide an additional reason why firms should offer multiple tariffs rather than a uniform nonlinear pricing plan to extract maximum consumer surplus.

A Primer on ACTA What Europeans Should Fear about the Anti-Counterfeiting Trade Agreement

The European Commission recently published the first official draft of the Anti-Counterfeiting Trade Agreement (ACTA). The article describes the institutional background of the negotiations on ACTA and its relationship to the existing legal framework. The civil enforcement provisions and the Internet chapter are compared with the international and European instruments in the field. For the most part, ACTA will not oblige EU member states to enact rules that go beyond the already established European standards. But stricter rules could be implemented regarding injunctions against non-infringing intermediaries, strict liability rules for damages, and ex parte measures in preliminary proceedings. According to the published draft, the termination of user accounts in the case of repeated intellectual property infringement will not be mandatory for member ACTA states.
