What are the two conditions that are met if a consumer is maximizing utility?
Suppose a consumer has a budget of $200 to spend on two goods, X and Y, whose prices are $20 and $10, respectively.
If the consumer is observed to buy 5 units of X and 10 units of Y, where the respective Marginal Utilities of X and Y are, 50 and 40 utils, is the consumer in equilibrium? Explain why or why not.
If the consumer is not in equilibrium under conditions in d), suggest another combination that would possibly achieve equilibrium. Explain your answer.
Revealed Preference is when an individual's behavior reveals information about a person's tastes and preferences,i.e. what he likes and dislikes and how much he likes or dislikes a good.
The individual demand schedule and an individual's demand curve reveals a person's tastes and preferences for a good. Specifically it reveals how much each successive unit of the good he consumes is worth to him.
We can say this differently by saying the maximum price a person is willing to pay for a particular unit of the good is how much that unit of the good is worth to him. This value is revealed by his behavior or his willingness to voluntarily give a certain amount of money in exchange for that unit of the good. In other words, how many units of a good a person demands/buys at any given price. Look at the image.

Nick says that if Frodo buys more beer when the price of beer goes up, then beer must be an inferior good for Frodo. If, on the other hand, he buys less beer when the price of beer goes up, then beer must be a normal good for Frodo. Sofia disagrees: "Normal and inferior goods are about income changes, not price changes. Therefore, we do not have enough information: beer could be an inferior or normal good in either of these cases." Do you agree or disagree? Carefully explain your point of view. Support your argument with graphs of income, substitution and total effects (please put beer on the horizontal axis and the other goods on the vertical axis). Please assume that Frodo's preferences over beer and other goods are strictly convex and satisfy "more is better" assumption.arrow_forward
- When consumers have a budget, their utility is maximized by buying a combination of goods such that the marginal utility per dollar is the same for all of these goods. This is because if this were not the case, it would mean that the consumer hadn't used up their entire budget. of their insatiability. if a consumer could get higher marginal utility from one good than from others, they would want to buy more of that good, and less of others. if a consumer could get higher marginal utility from one good than from others, they would want to buy less of that good, and more of others. it guarantees them some variety.arrow_forwardillustrate diagrammatically how the optimal choice of a consumer changes as a result of a decrease in the consumer’s income, when one of the two goods on offer is a normal good. To complete this activity you must have a clear understanding of how the optimal choice is determined, what happens to the budget constraint as the consumer’s income decreases, and the concept of a normal good.arrow_forwardGive a real-life example (from your daily life) that illustrates total utility rising as marginal utility declines.arrow_forward
- please give answer step by steparrow_forwarda)Assume that the typical consumer always spends a small share of her overall budget on Vietnamese meals and use the utility maximization conditions to find the demand for Vietnamese food of the typical consumer (keep in mind that since utility is quasi-linear, you can find demand without information about the consumer’s weekly budget). b) Sum across consumers to find the weekly market demand for Vietnamese meals in NYC.arrow_forwardAnother instance when people are likely not to spend a dime (or a minute) on an item is when they have a dislike for mixing the item with other items available. In this case, we say the consumer has ‘non-convex preferences’ and indifference curves are bowed out from the origin. In plain language, the consumer has a preference for binging. We often feel this way towards our favorite social media app. Consider a kid who has four hours a day to spend on social media. They enjoy spending time on Snapchat (x) or spending time on Twitter (y). a) Write the kid’s time constraint and illustrate it in a graph where you measure time spent on Snapchat along the horizontal axis and time spent on Twitter along the vertical axis. This kid’s utility from time spent on Snapchat and time spent on Twitter is U(x,y) = 4x2+ y2. b) In your graph, draw a couple of the kid’s indifference curves. Notice how the kid’s |MRSY,X| increases along each curve as he spends more time on Snapchat and less time on…arrow_forward
- You are choosing between two goods, X and Y, and your marginal utility from each is as shown in the following table. If your income is $9 and the prices of X and Y are $2 and $1, respectively, what quantities of each will you purchase to maximize utility? What total utility will you realize? Assume that, other things remaining unchanged, the price of X falls to $1. What quantities of X and Y will you now purchase? Using the two prices and quantities for X, derive a demand schedule (a table showing prices and quantities demanded) for X.arrow_forwardTo reach consumer equilibrium, which of the following consumption choices must be made? The total utility per dollar spent on Good X must equal the total utility per dollar spent on Good Y. The total utility of Good X must equal the total utility of Good Y. The marginal utility of Good X must equal the marginal utility of Good Y. The marginal utility per dollar spent on Good X must equal the marginal utility per dollar spent on Good Y.arrow_forwardAmanda consumes three different products: apple (x), orange (y) and banana (z).
