Microeconomics I unit 1 part 1 የሸማቾችን ውሳኔ መተንተን

Utility is strictly an ex ante concept; that is, it measures the way an individual feels about a commodity before the individual buys or consumes it. Utility is the satisfaction that an individual expects to get, not what he actually gets. You may want to take a bottle of Beer and enjoy yourself. When you decide to buy that bottle of Beer, what matters the most is the satisfaction you expect to derive from its consumption. In fact, the consumption may make you feel uncomfortable – that is irrelevant economically. Cardinal utility approach took the view that utility is measurable and additive. In this regard a measure called util can be employed.
