An Empirical Analysis of Indirect Network Effects in the Home Video Game Market

We explore the indirect network effect in the market for home video games. We examine the video game console makers' strategic choice between increasing demand by lowering console price and by encouraging the growth of software variety. We also explore the existence of an applications barrier to entry in the console market, and find that there is little evidence for such a barrier. Finally, we assess the applicability of the model to out-of-sample situations, to look at whether our model and previous similar models can generalize to other markets for purposes of marketing or antitrust inquiry. We find that the model generalizes reasonably well to the Japanese market for the same generation of gaming systems, but poorly to previous generations in the US market

Understanding how people forget is one of the fundamental goals of the science of memory. Recent studies indicate that humans can voluntarily regulate awareness of unwanted memories by stopping the retrieval process that would ordinarily bring past experience into awareness. Event-related potential (ERP) research on memory retrieval reveals that electrophysiological effects with specific timing and scalp topography serve as markers of memory processes. This systematic review examines the literature regarding EEG alterations in memory suppression, highlighting their results on electrophysiological indicators. A systematic review from January 2007 to November 2017 was conducted using PubMed, Embase and ScienceDirect databases. As results, 12 studies were eligible for inclusion. Quantitative EEG can be a objective tool for studying the mechanisms involved in memory suppression. There is evidence that a parietal positivity around 400-800ms after cue presentation is an ERP marker of conscious recollection during memory retrieval and a larger N2 deflection during retrieval suppression predicted greater suppression-induced forgetting
