We define a large game describing a continuum of heterogeneous agents interacting with a ride-sharing platform. Each player’s life consists of two states: Riding and not riding. In the riding phase the player needs access to a transportation service to perform a ride which is of positive value to her. The ride can be obtained in three ways: (1) Drive her own car, which is only an option if the player owns a car. (2) Find an empty seat through the ride-sharing platform, which depends on how many seats other players are offering. Or (3), use public transport, assumed to be always available. Players are differentiated across two characteristics, the utility they derive from a trip and the wage they may earn while not on a trip. Each player is offered the same set of strategies to interact with the platform. We assume players have higher utility for private transportation as opposed to public transportation. Additionally, money can be earned from offering seat capacity to the platform, thus players may choose to forgo their wage and become full time service providers to the platform instead. We study equilibria, social welfare and congestion in our game and compare these statistics to a game without the platform. This is joint work with Harald Bernhard and Saif Benjaafar.
Talk 2: Fundamentals and Recent Advances in 5G Wireless Systems

With 4G cellular technologies now beginning to be deployed widely around the world, the fifth generation (5G) mobile and wireless communication technologies are emerging into research fields. New services, applications and devices will drive requirements on data rate, ubiquity of data services, latency, cost, and reliability and further drive data traffic growth. Networks, services, and devices will be more heterogeneous and the need to connect billions of devices to the network will emerge. To meet the above challenges, 5G wireless systems will require a mix of new system concepts to boost spectral efficiency, energy efficiency, latency, and the network design. In this talk, we will introduce this exciting research area and discuss some of our recent work that can potentially help to meet these challenges in 5G wireless systems.
