This paper is about the utility of cycle of money with the minimum mixed savings. This means that we examine the crucial points of tax policy and public policy which are the best for the increase of consumption and of the investments, subject to the case that there exist the mixed savings in the minimum level. Therefore we have an analysis which based on the utility of the public sector and the utility of the uncontrolled enterprises. Thence, it is plausible to extract conclusions about the utility of cycle of money, showing the points and the behaviors of any economy when there are the mixed savings and are omitted the escaped savings.
