I dont believe that marginal utility can be negative. Actually, owning a good or a service does not mean that we have to consume it (for instance, owning or buying many cookies does not necessarily imply that we will have to eat all of them). So, I think the lowest possible value of MU is zero. Why do we need to assume that rational individuals would literally consume the good or service if they know, ex ante, that it would harm them or decrease their satisfaction level !!!
