METHODS: Looking at economic assessments of consumable goods, discounting is only applied to the monetary value. Money is a flexible instrument for trading purposes, but subject to value changes over time. With money, product value can be expressed with value-based pricing processes the consumer is willing to pay. Money is then discounted in that process because its amount allows to do other things within different time periods. However, the outcomes of the processes that can be instantaneous or continuous such as energy (joules), distance travelled (km), cooling periods (temperature), are not part of the discounting if the outcome is produced over a long duration period.
