Such a graph comes handy for the case that we have limits for the budget in each year. If we aim to stimulate the market in periods longer than one step, then we can work with this figure in an Ising simulation of the network of firms. If for example instead of one Monte Carlo step we aim to stimulate the market in three steps, then it means that the size of H is about 0.42. This strength suggests the value of 1.25 for τ be equal to H. This means that in this case, the total bill is about 0.62ΔGDP. So for a three year stimulation, in each year we need a stimulation around 0.21ΔGDP. For a two-year spending stimulation we need about 0.53ΔGDP for the whole bill and 26%ΔGDP for each year.
