Jane always gets twice as much utility from an extra ballet ticket as she does from an extra basketball ticket, regardless of how many tickets of either type she has. Draw Jane's income-consumption curve and her Engel curve for ballet tickets.

Key Concepts

Marginal Utility

Marginal utility is the additional satisfaction a consumer gains from consuming one extra unit of a good. Understanding marginal utility is fundamental for determining optimal consumption choices, particularly when comparing how much extra satisfaction is achieved from different goods.

Engel Curve

The Engel curve depicts the relationship between a consumer’s income and the quantity of a specific good purchased, with prices remaining constant. It is used to analyze how consumption of the good changes as income changes, indicating whether the good is normal or inferior based on the direction of the relationship.

Income-Consumption Curve

The income-consumption curve shows the combinations of goods a consumer chooses at various income levels when prices are held constant. It illustrates how changes in income affect the quantity of goods purchased and helps in understanding the effect of income on consumer demand.

Utility Function

A utility function is a mathematical representation of a consumer’s preferences that assigns a value (or level of satisfaction) to each possible bundle of goods. It is key to analyzing consumer behavior as it allows for the comparison of different bundles by indicating which combinations of goods provide higher or lower satisfaction.

Transcript

00:01 So jane always gets twice as much utility from an extra ballet ticket as she does for an extra basketball ticket.

00:11 So she gets two times more utility from a ballet ticket, an extra ballet ticket as she does from an extra basketball ticket.

00:31 Now regardless of how many tickets of either type she has, she gets two times more utility for the extra ballet than a lot of.

00:39 That she does for the basketball.

00:42 So we're to draw our income consumption curve and what we're to draw angels ' curve for ballet tickets.

00:51 So we need to know that ballet ticket and basketball tickets are going to be perfect substitute good for jane.

01:00 So we need to know that.

01:04 So ballet tickets and basketball tickets are perfect substitute for jane.

01:37 So this means that she will consume either all the ballet tickets or all basketball tickets depending on the price of both right because they are substituted and substitute goods means you can go for one of them so basically so depends on your on the price or the or the or the or depends on an income that will determine all the ballet tickets or all the basketball tickets so when the price of ballet tickets are less than the price of basketball tickets then she'll choose ballet and when the ballet tickets are more than twice the price of basketball tickets then she will choose basketball so we can see that she can consume either of all based depending on the price so when the price of ballet tickets are less than the price of basketball tickets, then she will choose ballet, obviously...
