  • What does optimum consumption represent for a consumer?
    Optimum consumption represents the maximum utility a consumer can achieve within their budget constraint.
  • How is marginal utility per dollar calculated for a good?
    Marginal utility per dollar is calculated by dividing the marginal utility of a good by its price.
  • Why do we use marginal utility per dollar instead of just marginal utility?
    We use marginal utility per dollar because goods have different prices, so this measure allows us to compare utility gained per dollar spent across goods.
  • What is the rule for optimum consumption regarding marginal utility per dollar?
    Optimum consumption occurs when the marginal utility per dollar spent is equal for all goods.
  • What economic principle explains why marginal utility decreases as more units are consumed?
    The principle of diminishing marginal utility explains that each additional unit consumed provides less satisfaction than the previous one.
  • In the example, what is the price of eggs and coffee?
    Eggs cost \$2 each and coffee costs \$1 each.
  • If the marginal utility of the first egg is 20, what is its marginal utility per dollar?
    The marginal utility per dollar for the first egg is 10 (20 divided by \$2).
  • How do you determine if a consumption bundle is affordable?
    A bundle is affordable if the total spending on all goods does not exceed the consumer's income.
  • What is the optimum consumption bundle for \$10 income in the example?
    The optimum bundle is 3 eggs and 4 coffees, which maximizes utility and spends all \$10.
  • What happens to total utility if a consumer spends all their income on only one good?
    Total utility is less than the maximum possible because the marginal utility per dollar is not equalized across goods.
  • How do you check if a bundle is optimum for a given budget?
    Check if the marginal utility per dollar is equal for all goods and if the total cost matches the budget.
  • What is the total utility from consuming 5 eggs and 0 coffee in the example?
    The total utility is 54, calculated by summing the marginal utilities of each egg.
  • Why does the optimum bundle change with different income levels?
    The optimum bundle changes because the consumer can afford different combinations of goods as their budget increases.
  • What is the optimum bundle for a \$5 budget in the example?
    The optimum bundle is 1 egg and 3 coffees, where marginal utility per dollar is equal and total cost is \$5.
  • What is the key step to finding optimum consumption in practice?
    Calculate marginal utility per dollar for each good, find where they are equal, and ensure the bundle fits within the budget.
