Google's Anti-Competitive and Unfair Practices in Digital Leisure Markets
The purpose of this article is to reflect on the critical use of commitments in the Google case and to analyse and review the matrix of facts that have been highlighted in the academic and practitioner literature. Therefore, the core area of reflection in this contribution are relevant markets; barriers to entry; network and lock-in effects; dominance; and potential anti-competitive, as well as unfair practices as regards commercial advertisements. The analysis of the online search-engine market is complemented by the comparative insights offered by the US class action against Google’s Android mobile applications. In the EU, a similar trend is noticeable in the complaining tone of Google’s competitors. Coupled with the transitional period of the mandate of the newly appointed Commissioner for Competition and the political sensitivity over the potential to misuse search-engine users’ personal data to serve commercial purposes, such as boosting its advertising revenues, the giant Google swims in uncertain waters.
Online Platforms and Vertical Integration: The Return of Margin Squeeze?
When competition authorities struggle to assess abusive practices by online multi-sided platforms, the issue does not appear to be defining markets or determining market power; rather, the difficulty is finding a fitting theory of abuse. In the search for such theories, one candidate has been overlooked: margin squeeze. This infringement has for the most part been confined to the telecom sector, but its potential reaches beyond. Indeed, the conduct of online platforms could force margin squeeze out of retirement. This article starts from the foundations of margin squeeze theory, laying out the core principles and addressing possible misconceptions. The article then investigates whether margin squeeze theory could be applied to online platforms with the help of three case studies (involving app stores, search engines and online marketplaces). Before concluding, it contemplates the idea of neutrality underlying margin squeeze and related policies such as network neutrality.
Magnetic plasma confinement for laser ion source.
A laser ion source (LIS) can easily provide a high current beam. However, it has been difficult to obtain a longer beam pulse while keeping a high current. On occasion, longer beam pulses are required by certain applications. For example, more than 10 micros of beam pulse is required for injecting highly charged beams to a large sized synchrotron. To extend beam pulse width, a solenoid field was applied at the drift space of the LIS at Brookhaven National Laboratory. The solenoid field suppressed the diverging angle of the expanding plasma and the beam pulse was widened. Also, it was observed that the plasma state was conserved after passing through a few hundred gauss of the 480 mm length solenoid field.
