"A Missing Step in the Modernisation Stairway – Any Role for Block Exemption Regulations in the realm of Regulation 1/2003?" with A. Sánchez

Block exemption regulations (BER) survived the modernisation of EU competition law. According to the Commission, they play a major role in the system instituted by Regulation 1/2003. Some authors consider that BER are conceptually hard to nest within the new system, but that they provide legal certainty. Others adopt a more critical approach and propose their axing. This paper adopts the latter approach. In view of the mixed messages that the Commission has been sending in the review of existing general and industry specific BER, this paper revisits the institution of BER, its justification and need in the decentralised system brought forward by Regulation 1/2003 and the more economic approach to EU competition law. After stating the initial justification for BER under the prior enforcement system, the paper stresses the difficulties for their fitness within the new paradigm, focusing on the distortions that they may generate for an effective and consistent enforcement of EU competition law. In order to complete the modernisation of EU competition law in a second wave (that is, as a consequence of the current revision of Regulation 1/2003), the paper recommends a clear-cut policy to abrogate all BER and to issue substitutive guidelines in exchange.

Access Barriers to Competition

While data were always valuable in a range of economic activities, the advent of new and improved technologies for the collection, storage, mining, synthesizing, and analysis of data has led to the ability to utilize vast volumes of data in real-time in order to learn new information. Part I explores the four primary characteristics of big data: volume, velocity, variety, and veracity and their effects of the value of data. Part II analyzes the different types of access barriers that limit entry into the different links of the data value chain. In Part III, we tie together the characteristics of big data markets including potential entry barriers, to analyze their competitive effects. The analysis centers on those instances in which the unique characteristics of big data markets lead to variants in the more traditional competitive analysis. Our analysis suggests that the unique characteristics of big data have an important role to play in analyzing competition and in evaluating social welfare.
