  Economists modeled self-control problems in decisions of people with the
time-inconsistence preferences model. They argued that the source of
self-control problems could be uncertainty and temptation. This paper uses an
experimental test offered to individuals instantaneous reward and future
rewards to measure awareness of self-control problems in a tempting condition
and also measure the effect of commitment and flexibility cost on their
welfare. The quasi-hyperbolic discounting model with time discount factor and
present bias at the same time was used for making a model for measuring
awareness and choice reversal conditions. The test showed 66% awareness of
self-control (partially naive behaviors) in individuals. The welfare
implication for individuals increased with commitment and flexibility costs.
The result can be useful in marketing and policy-making fields design precisely
offers for customers and society.
