Suppose that there are only two goods (x and y) and good y is an inferior good. The demand curve for good x cannot be vertical. True or false. Explain your answer graphically and intuitively.
Good X is normal good whose demand falls when price of its rises or income falls.
Good Y is inferior good whose demand falls when income rises.
The demand curve of good X cannot be vertical is false as when price increases, real income level falls causing consumer to consume less of the goods but quantity demanded is same. As there is always a positive relationship between level of income and consumption of a normal goods.

1a. Consider two goods: x and y where y is a numeraire good. Suppose that x is a normal good. Graphically derive the demand curve for good x based on the indifference curve framework by working out the optimal consumption choices when the price of good x falls. 1b. Rework 1a but now good x is an inferior good (but not a Giffen good).
Assume we live in an economy with only two available goods, X and Y. Suppose that we experience an increase in consumer income. If Y is an inferior good, then what cannot happen from the choices below? a. decrease the demand for Y. b. decrease the demand for X. c. increase the demand for X. d. make the consumer better off.
A consumer buys two goods, good X and a composite good Y. The utility function is given as ?(?,?) = ? + ?√? . 1) Derive the demand function for good X.(5 marks) 2) Is good X a normal or an inferior good? Why? ( 5 marks) 3) Suppose that initially ?? = $1 and then it falls and becomes ?? = $0.5. Also suppose that Income=$10. Calculate the substitution effect, income effect, and the price effect and show...
Consider a two good world, with commodities X and Y. If Y is an inferior good, then an increase in consumer income cannot a. Decrease the demand for Y B. Decrease the demand for X c. Increase the demand for X d. Make the consumer better of

2. Suppose there are only two goods, good X and a composite good. A rational consumer with a weekly income of $100 consumes 5 units of good X when the price of good X is $10 per unit. When the price of good X decreases to $5 per unit, she consumes more of good X; but her expenditure on good X decreases. True or False: If follows that her price-consumption curve must...
Suppose Norah consumes only two goods, x and y. Which of the following statements MUST be true? (Note, consider each statement independently) 1. If the price of x increases keeping income and price of y fixed, she will consume more of x if x is inferior good. II. If the price of x increases keeping income and price of y fixed, she will consume more of y if y is an inferior good. III. If the price of y increases...
A consumer buys two goods, good X and a composite good Y. The utility function is given as U(X, Y) = 2X1/2+Y. The demand function for good X is X = (Py/Px)2. (Edit: The price of X is Px, the price of Y is Py.) Suppose that initially Px=$0.5 and then it falls and becomes Px=$0.2 Calculate the substitution effect, income effect, and the price effect and show the answer graphically.
. Suppose the only two goods you purchase are X and Y. One day the price of X falls. Illustrate your old and new budget lines. Illustrate the substitution and income effects on your consumption of X assuming X is a normal good. Now do the same assuming X is an inferior good. (2 pts)
Imagine a representative consumer, whose utility for apples (X) and all other goods (Y) can be represented in a Cobb-Douglas form. 1. Please graphically represent consumer indifference curves, given prices Px and Py and the budget constraint M. 2. What will happen to consumer utility and optimal bundle if consumer income (budget) increases and apples are a necessity good? Please show graphically and explain the intuition. 3. What will happen to consumer utility and optimal bundle if apple price decreases...
Suppose that a there are two goods, X and Y. The price of Good X is $5 and the price of Good Y is $8. The seller of Good X offers a deal where if a consumer buys 1 unit of Good X they pay full price, but the second unit of Good X is only $2. Calculate the slope of the budget constraint between 1 unit of Good X and 2 units of Good X. (Remember to include a...
