5) In no more than five (5) lines of typed text below this question describe the role of “marginal utility per dollar” in decisions whether to purchase goods and services.
Marginal utility per dollar is the
part of the marginal principle of the economics that is used to
calculate the marginal utility per dollar of each additional unit
of goods and services purchased. With each additional purchase of
goods, the utility decreases (as per the diminishing marginal
utility rule) and marginal utility per dollar also comes down.
Here, the buyer compares the marginal utility per dollar of any
unit with the purchase of another good and marginal utility per
dollar of that good. If the marginal utility per dollar of good 1
is less than the marginal utility per dollar of good 2, then good 2
will be purchased and good 1 will not be purchased. Here, the rule
of marginal utility per dollar will help in maximizing the utility
per dollar spent.
The rule is also used to create a balance when different factors of
production are purchased. At equilibrium, marginal utility per
dollar of each factor of production will be equal for all the
factors of production.
