Duopoly experimentation: Cournot competition
1999
Abstract This paper analyzes learning behavior in an industry facing uncertainty. We consider a duopoly game where firms have imperfect information about market demand and they learn through observing market prices. The main body of our study consists of showing how firms make the price a more informative signal through their experimental behavior, and how this behavior compares to its monopoly counterpart. We extend previous analysis to the case where the demand unknown parameter takes values on the real line. We also find that experimentation under Cournot duopoly is smaller than under monopoly whenever the demand's unknown parameter is sufficiently precise.
Consolidated challenge to social demand for resilient platforms : Lessons from Uber's global expansion
2017
Many in the industry see the ride-sharing company Uber as the significant advancement through information and communication technology (ICT) particularly of the digital service platform and sharing economy. Uber has been exploring the new frontier of the ICT-driven disruptive business model (IDBM) and succeeded in its global expansion to over 479 cities in more than 75 countries worldwide in June of 2016. Such rapid expansion provides constructive insights regarding the significance of IDBM, not only in transportation but also in almost all other business fields. While at the same time Uber's legal battles in some cities around the world raise a serious question regarding the rationale of I…
Sorveglianza sui lavoratori, protezione dei dati personali ed azione collettiva nell’economia digitale
2019
Il saggio mette in luce i rischi legati alle concrete modalità di funzionamento e di organizzazione delle piattaforme digitali ed esamina il costante uso di una forza lavoro estremamente flessibile, con una disponibilità just-in-time, retribuita solo a prestazione, e sottoposta a fortissimi controlli elettronici.
A New Method for the Price Determination of the Reactive Power Supply
2006
This paper addresses the development of an accurate model for the pricing of reactive power supply as an ancillary service. Reactive power supply is one of the most important ancillary services in the field of transmission systems security. The present work is focused on building a reactive power market at which the Distributors can also take part in injecting reactive power at the connected HV/MV nodes. The authors have studied the particular case of the reactive power supplied by sub-transmission or distribution networks, connected to the nodes of the transmission system. The aim of this work is to establish a reactive power price by crossing demand and offer curves.
Mean-field games and dynamic demand management in power grids
2013
This paper applies mean-field game theory to dynamic demand management. For a large population of electrical heating or cooling appliances (called agents), we provide a mean-field game that guarantees desynchronization of the agents thus improving the power network resilience. Second, for the game at hand, we exhibit a mean-field equilibrium, where each agent adopts a bang-bang switching control with threshold placed at a nominal temperature. At equilibrium, through an opportune design of the terminal penalty, the switching control regulates the mean temperature (computed over the population) and the mains frequency around the nominal value. To overcome Zeno phenomena we also adjust the ban…
Lieu de résidence et discrimination salariale
2010
Ziel dieses Artikels ist es, die Lohnabweichungen zwischen Jugendlichen, die in sensiblen städtischen Zonen wohnen, am Ende ihrer Ausbildung und denjenigen, die zwar nicht in einer solchen Zone leben, die aber in städtischen Einheiten mit solchen Zonen wohnen, unter Berücksichtigung möglicher Barrieren beim Zugang zu bestimmten Beschäftigungen und insbesondere zu den Arbeitsplätzen von Führungskräften zu untersuchen. In Anknüpfung an Brown, Moon und Zoloth (1980) schlagen wir eine Zerlegung der Lohnabweichungen vor, bei der die Möglichkeit einer Differenzierung beim Zugang zu bestimmten Beschäftigungen entsprechend der Art des Stadtviertels, in dem die Jugendlichen wohnen, berücksichtigt wi…
Dans quelle mesure les préférences individuelles contraignent-elles le développement du marché de l'assurance dépendance ?
2015
Dans un contexte de vieillissement de la population, différents scenarii sont envisagés pour réformer l’organisation et le financement de la prise en charge des personnes âgées dépendantes. La place de la prévoyance individuelle dans le financement de la dépendance est à ce titre largement débattue. À l’heure actuelle, malgré des restes à charge potentiellement conséquents, peu d’individus disposent d’une couverture assurantielle. Cet article vise à enrichir la littérature existante en évaluant dans quelle mesure les préférences observées dans la population limitent cette couverture. Nous mobilisons pour cela l’enquête Patrimoine et préférences vis-à-vis du temps et du risque (Pater) de 201…
Dynamic Demand and Mean-Field Games
2017
Within the realm of smart buildings and smart cities,\ud dynamic response management is playing an ever-increasing\ud role thus attracting the attention of scientists from different\ud disciplines. Dynamic demand response management involves a\ud set of operations aiming at decentralizing the control of loads\ud in large and complex power networks. Each single appliance\ud is fully responsive and readjusts its energy demand to the\ud overall network load. A main issue is related to mains frequency\ud oscillations resulting from an unbalance between supply and\ud demand. In a nutshell, this paper contributes to the topic by\ud equipping each signal consumer with strategic insight. In particu…
Information Sharing and Channel Construction of Supply Chain under Asymmetric Demand Information
2014
Information sharing and marketing channel building have become an important problem of supply chain management theory and practice. The research of information sharing focused on traditional channel of supply chain between upstream and downstream enterprises; however, the research ignores the behavior of information sharing with potential entrants and composite structure characteristics about traditional marketing channel with the direct channel. This paper uses the model to research the effects brought about sharing demand information with potential entrants and building marketing channel, which reveals information sharing and channel building mechanism in the supply chain. The study found…
