For duopoly models, we analyse the concept of coarse correlated equilibrium using simple symmetric devices that the players choose to commit to in equilibrium. In a linear duopoly game, we prove that Nash-centric devices, involving a sunspot structure, are simple symmetric coarse correlated equilibria. Any small unilateral perturbation from such a structure fails to be an equilibrium.

PURPOSE As a rapidly growing new health care delivery model in the United States, retail clinics have been the subject of much debate and controversy. Located physically within a retail store, retail clinics provide simple acute and preventive services for a fixed price and without an appointment. Some hope that retail clinics can be a new safety-net provider for the poor and those without a pr...

We designed and deployed a conceptually simple multi-media annotation tool called the Microsoft Research Annotation System. We expected it to be widely useful in education settings with little or no modification. In a series of deployments over three years we encountered a surprising range of specific interface requirements. We ultimately shifted from an application focus to a platform focus, f...

This paper studies the effects of advertising in a Bertrand duopoly model with informative advertising, which is an extension of Grossman and Shapiro (1984). It introduces spillover advertising effects on top of the direct advertising effects. Also, the model involves R&D activities, which make the model dynamical. It is shown that the spillover effects would make the environment more monopolis...

We consider an infinitely lived duopoly with asymmetric costs and study the incentives of firms to collude or compete in supply functions under possibility technology licensing. Simulating subgame-perfect Nash equilibria alternative industry organizations, we show that licensing makes collusion harder; but it always has a positive effect on welfares consumers less efficient firm duopoly.

We investigate the effect of multimarket contacts on the privatization policy in mixed duopoly with price competition. There are two markets, one of which is served solely by the state-owned public firm, and the other is served by both public and private firms. Two markets are linked by the production technology of the public firm. In the general model, we first show that privatization is never...

The mere act of choosing implies giving up possible alternatives and is therefore likely to generate a feeling of regret, which agents anticipate at the decision stage. In line with regret theory, I study the impact of anticipated regret on the decisionmaking process. The key feature of the model consists in considering biased regret anticipations. I thus describe the combined effect of cogniti...

New retail is an innovative business model combining online and offline (O2O) shopping experiences (Alibaba Gorup, 2018) discovering how to adapt the digital transformation. Several factors that could affect consumer experience when include ease of accessing using web, Hedonic Utilitarian Features, Convenience, personalization, social interaction, compatibility on various devices. The study aim...
