Consumption theory The rational optimization framework In their studies of consumption, economists generally draw upon a common theoretical framework by assuming that consumers base their expenditures on a rational and informed assessment of their current and future economic circumstances. For example, economists usually assume 1 that the urgency of consumption needs will decline as the level of consumption increases this is known as a declining marginal utility of consumption2 that people prefer to face less rather than more risk in their consumption people are risk-averseand 3 that unavoidable uncertainty in future income generates some degree of precautionary saving. Within the rational optimization framework, there are two main approaches. The standard version of the life-cycle model also assumes that consumers would prefer to spend everything before they die i.

More recent theoretical approaches are based on behavioral economics and suggest that a number of behavioural principles can be taken as microeconomic foundations for a behaviourally-based aggregate consumption function.

In economics, a good is said to be rivalrous or rival if its consumption by one consumer prevents simultaneous consumption by other consumers, or if consumption by one party reduces utility/ability to use to another.
A good is considered non-rivalrous or non-rival if, for any level of production, the cost of providing it to a marginal (additional) individual is zero. Importance of Consumption in Economics!
