>I want so see the effects on the total economy. If for example UBI leads to massive inflation it would completely nullify the UBI.

Actually that would be highly desireable because it would mean the UBI acts as "employment of last resort" rather than free money, except you don't have to do anything to keep your job. It also means that every job will pay more than UBI which means there is no incentive not to work. Considering the financing challenges you want as few people as possible on the UBI.
