Some notes and comments on the efficient use of information in repeated games with Poisson signals

In the present paper we characterize the optimal use of Poisson signals to establish incentives in the “bad” and “good” news models of Abreu et al. (1991). In the former, for small time intervals the signals’ quality is high and we observe a ”selective” use of information; otherwise there is a “mass” use. In the latter, for small time intervals the signals’ quality is low and we observe a ”fine” use of information; otherwise there is a “non-selective” use.
