Titulo: "On the Time Consistency of Collective Preferences"
Expositor: Dr. Luis Alcala
Abstract: This paper develops a collective choice model of consumption and savings. Preferences of time consistent agents are aggregated so they satisfy Pareto optimality with time-varying utility weights. Under standard separability assumptions, collective preferences are nonstationary and time dependent, but time consistent in the sense of Halevy (2015).
