answer

-shows that consumers can only buy "affordable" bundles of goods that do not cost more than their income -slope= opp. cost

question

How does a consumer's budget constraint reflect changes in income?

answer

-income and prices define a consumer's budget constraint -when income is limited, the real cost of any single good or service is the value of the next preferred other goods and services that could have been purchased with the same amount of money -a change in the price of one good may change the entire allocation -some goods may be demanded more, while others may be demanded less

question

Discuss two general assumptions about the properties of consumer utility.

answer

question

Diminishing Marginal Utility

answer

as you increase consumption of a product, you get less and less marginal utility from consuming each additional unit of that product ex//: all you can eat buffet

question

What are the properties of indifference curves?

answer

-have a negative slope (willing to give up some to get more of other goods) -further from the origin (0,0), preferred (the more, the better) -convex toward 0 (decreasing marginal utility -Indifference curves cannot cross

What is MRS?

answer

Marginal Rate of Substitution slope of the indifference curve at a given point -willingness to trade between horizontal & vertical axis

question

Substitution effect

answer

-a decline in the price of a product, that product becomes 'relatively' cheaper, becoming more attractive relative to potential substitutes -the change in consumption of the good due to changes in its relative attractiveness compared to alternatives
