This short note studies the simple arithmetic properties of multi-year bonus allocation systems, as recently implemented in the population of teacher-researchers, with the PEDR on the one hand, and with component 3 of the RIPEC on the other.In the first stage, we study an initial model in which the entire population applies, in order to highlight the effect of the multi-year nature of the award: the success rate of an application is very different from the frequency with which an individual receives the bonus.Secondly, we take into account the fact that part of the population is not a candidate, with cross-influences between the competition participation rate and the individual success rate.In the light of available statistics on agent behavior, we will discuss the possibility of RIPEC training a large part of the population.
