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 thatâ€¦ (More)

We consider a class of symmetric two-person quadratic games where coarse correlated equilibria â€” CCE â€” (Moulin and Vial 1978) can strictly improve upon the Nash equilibrium payoffs, while correlatedâ€¦ (More)

We consider the well-analyzed abatement game (Barrett 1994) and prove that correlation among the players (nations) can strictly improve upon the Nash equilibrium payoffs. As these games are potentialâ€¦ (More)

We consider a class of quadratic potential games and prove that (simple symmetric) coarse correlated equilibria (as introduced by Moulin and Vial 1978) can strictly improve upon the Nash equilibriumâ€¦ (More)

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 thatâ€¦ (More)

In a coarse correlated equilibrium (Moulin and Vial 1978), each player finds it optimal to commit ex ante to the future outcome from a probabilistic correlation device instead of playing any strategyâ€¦ (More)

The periodic event scheduling problem (PESP) is a well studied problem known as intrinsically hard, but with important applications mainly for finding good timetables in public transportation. Inâ€¦ (More)

We study a robust toll pricing problem where toll setters and users have different level of information when taking their decisions. Toll setters do not have full information on the costs of theâ€¦ (More)

We study the toll pricing problem when the non-toll costs on the network are not fixed and can vary over time. We assume that users who take their decisions, after the tolls are fixed, have fullâ€¦ (More)
