Stage v. Individual nodes update information again. The government intervention switches the updating rule to (2) xi,t+1=λxd+(1−λ)∑k∈Oiδxk,tyk+xi,tyi∑k∈Oiyk+yi, which is also the final amount of the information after government intervention. In addition, we assume that the amount of information of initial information holders (those who have information in period 0) is constant, i.e., they do not apply for Equations (1) and (2).
