Platform Rules: Multi-Sided Platforms as Regulators

This paper provides a basic conceptual framework for interpreting non-price instruments used by multi-sided platforms (MSPs) by analogizing MSPs as "private regulators" who regulate access to and interactions around the platform. We present evidence on Facebook, TopCoder, Roppongi Hills and Harvard Business School to document the "regulatory" role played by MSPs. We find MSPs use nuanced combinations of legal, technological, informational and other instruments (including price-setting) to implement desired outcomes. Non-price instruments were very much at the core of MSP strategies.Platforms, regulation, network effects, distributed innovation

Belief-free Price Formation

We analyze security price formation in a dynamic setting in which long-lived dealers repeatedly compete for trading with potentially informed retail traders. For a class of market microstructure models, we characterize equilibria in which dealers’ dynamic pricing strategies are optimal no matter the private information each dealer may possess. In a generalized version of the Glosten and Milgrom model, these equilibria deliver price dynamics reminiscent of well-known stylized facts: price/trading-flow correlation, volatility clustering, price bubble and inventory/inter-dealer trading correlation

Proceedings of The Multi-Agent Logics, Languages, and Organisations Federated Workshops (MALLOW 2010)

http://ceur-ws.org/Vol-627/allproceedings.pdfInternational audienceMALLOW-2010 is a third edition of a series initiated in 2007 in Durham, and pursued in 2009 in Turin. The objective, as initially stated, is to "provide a venue where: the cost of participation was minimum; participants were able to attend various workshops, so fostering collaboration and cross-fertilization; there was a friendly atmosphere and plenty of time for networking, by maximizing the time participants spent together"

An Architecture for Believable Socially Aware Agents

The main focus of this thesis is to solve the believability problem in video game agents by integrating necessary psychological and sociological foundations by means of role based architecture. Our design agent also has the capability to reason and predict the decisions of other actors by using its own mental model. The agent has a separate mental model for every actor

A Survey of the Ability of the Linux Operating System to Support Online Game Execution

Linux has suffered sluggish home user uptake due mainly to the dominance of rivals, and has seen numerous incarnations as a gaming platform fall flat. Gaming is a particularly sensitive application given its intensive bandwidth and system response requirements; these applications therefore place specific demands on the Operating System platform on which game play is supported. In this work, the ability of the Linux operating system to support execution of online games is explored through a survey of the state-of-the-art in this area. Given the recent increase in cloud-based online gaming, it can be concluded that the time is ripe for more widespread Linux uptake, especially in the gaming domain. This is particularly true today given the amount of exposure to Information Technology across society in general, and ongoing deployment of Internet of Things environments: Linux's open source, modular and freely customisable design may therefore not be as daunting as before, and the unique benefits of this platform may be exploited for the experiences it can bring to applications in general and, specific to the context of this work, players in their game play. This paper makes a unique contribution to the field: Although a number of articles are available within the general area of Linux and gameplay, a thorough survey on this issue has not been seen so far. This is therefore the gap to which this paper contributes

Empirical studies in labour and migration economics

This thesis consists of three empirical studies investigating topics in the fields of labour and migration economics, using a combination of administrative and survey data. The first study in labour economics seeks to answer the question whether international differences in earnings inequality between skilled and (relatively) unskilled workers can be explained by differences in the relative supply of and demand for skilled and unskilled workers across countries. Both the second and third studies are placed in the field of migration economics, dealing with the topical issue of refugee migration. Specifically, they investigate the social and attitudinal effects of the reception of refugees on host communities. The second study employs a case study of a town in rural Australia to examine how a large influx of refugees to the township has impacted social capital among the native residents. The third study broadens the context by using refugee centre data from all of the Netherlands over a number of years to link exposure to refugees to changes in natives’ attitudes to immigration. While the three studies differ (in parts) in the subfield, context and methodology of empirical microeconomics, a uniting factor is that they are motivated by important real-world problems, and that any conclusions drawn are based on the thorough analysis of a suitable dataset
