Chapter 6 Flashcards
What is the behavioral assumption in economics
individuals and firms maximize
their personal well-being and/or their profits.
May have other goals in addition: philanthropy and the well-being of others
The theory of individual maximization is based on
individuals must act in a rational manner in order to achieve their goals
What is cardinal utility
A measurable concept of satisfaction- not so achieved, also called measurable utility
Total utility is
A measure of the total satisfaction from consumption derived from consuming all of the units over a time period
Total utility is calculated as
The sum of marginal utilities
What is the principle of non-satiation
More is always better
Though more is always better, what happens with increasing units of the good
At the additional unit of good satisfaction goes down -> diminishing marginal utility
Formula for marginal utility
Marginal Utility = additional utility/ additional consumption or, MU = deltaU delta C ,
Total utility __ with the amount consumed, marginal utility __ with the amount consumed
Increases
Declines
MU is ___ of the TU function
a slope
How consumer should allocate income
Where it yields the greatest utility per dollar
When does consumer equilibrium occurs
when marginal utility per dollar spent on the last unit
of each good is equal.
Equilibrium for budget allocation
MUs/Ps=MUj/Pj
or
MUs/MUj=Ps/Pj.
Budget allocation rule
The consumer chooses the quantities based on marginal utility rather than on total utility
The law of demand states
The law of demand states that, other things being equal, more of a good is demanded
the lower is its price
