Refer to figure 6.1. Assume that L1 represents the budget line before a price change. Point C represents the:
A) uncompensated effect on an increase in the price of soup
B) compensated effect on a decrease in the price of soup
C) uncompensated effect on a decrease in the price of soup
D) compensated effect on an increase in the price of soup
Suppose that Alex's marginal rate of substitution (MRS) between good A and B is always equal to -2. The prices of the goods are $5 and $4 respectively. Alex's income is $20. Thus, his optimal consumption bundle must be (x*1,x*2) = (4,0), i.e., his demand for good A and good B is x*1 = 4 and x*2 = 0, respectively.
Is this true or false? If true, show the steps in full to justify and if it is false, show the correct demand and expalin in details.
True or false with reasoning:
1) _______When we claim that utility can be ordinally measured, we assume that the consumer is able to measure the total and marginal utility received when one extra unit of a commodity is consumed.
2)_______If MRS between two goods is constant, then having more of one good without having more of the other does not increase utility.
3)_______Marginal Utility increases until total utility is at a maximum and then marginal utility decreases.

- A consumer’s budget set for two goods (X and Y) is 600 ≥ 3X + 6Y. (LO2) a. Illustrate the budget set in a diagram. b. Does the budget set change if the prices of both goods double and the consumer’s income also doubles? Explain. c. Given the equation for the budget set, can you determine the prices of the two goods? The consumer’s income? Explain.arrow_forward- Create a consumer model that shows how economists explain the consumer choice between two products (X & Y) that maximize the consumer’s utility. Do not use numbers. Just graphs and detailed explanations. Show why the equilibrium point (tangency) shows the best bundle of X & Y and that any other point will not reflect a bundle that maximizes consumers' utility. Explain the income and substitution effect. Derive the demand function from the consumer theory. Do not use numbers. Just graphs and detailed explanationsarrow_forwardSuppose that a consumer's marginal rate of substitution at her current chosen bundle is MUx/MUy=3 but she can exchange X and Y at Px/Py=5. Should she keep her current bundle, or can she make herself better off by trading at these prices? Which good will she buy, and which will she sell?arrow_forward
- A consumer has $300 to spend on goods X and Y. The market prices of these two goodsare Px = $15 and Py = $5. (LO2)a. What is the market rate of substitution between goods X and Y?arrow_forwardConsider a consumer who wants to consume only two commodities and has an income of $250. Assume the price of good 1 is $25 per unit and the price of good 2 is $50 per unit. Now, inflation causes the price of good 1 to increase to $30 per unit, while the price of good 2 increases to $60 per unit. On the other hand, the consumer also gets a raise of $110 (so her new income is $360). What will happen to the consumption bundles (x₁, x₂)? How much units will increase for both x₁ and x₂?arrow_forwardRefer to Table 11W.1 and suppose the price of new product C is $2 instead of $4. How does this affect the optimal combination of products A, B, and C for the person represented by the data? Explain: “The success of a new product depends not only on its marginal utility but also on its price.”arrow_forward
- For each of the following, graphically decompose the total effect of the price change into the substitution and income effects on a well-annotated graph. Be sure to clearly label each of the three effects. 2. Paula’s preferences for goods x and y are given by the utility function, U = x 1/2 y 1/2 . Her income is $160, and the price of good y is always $20. Suppose the price of x starts at $20 and then decreases to $5. a. Calculate the income, substitution, and total effects of the price decrease on both goods. Show your work for full credit and round to 2 decimal places where appropriate. b. Use a clearly labeled graph to illustrate the total, income, and substitution effects of the price decrease on Paula’s consumption of goods x and y.arrow_forwardHari draws an indifference map between two goods A and B, and marks in points to show the combinations of A and B that he would buy if the prices of A and B remained the same but his income increased. Which of the following statements is false O a. The line is called an income consumption curve Ob. The line will always slope upwards to the right if both products are normal goods O C. The line will slope backwards or downwards at income levels where one product is an inferior good D.The line is called the budget linearrow_forwardQ1 please help me quickly!! Your budget is $200. The price of good 1 (x1) is $4 per unit, and that of good 2 (x2) is $3 per unit. Then, the equation for your budget line can be written as O 5x1 + 3x2 = 200 ◎ 4x1 + 3x2 = 200 ◎ 4x1+ 4x2 = 200 O 5x1 + 3×2 = 195arrow_forward
- John’s preferences for Orange (O) and lemons (L) are represented by the funtion U(O, L)= O+2L. The oranges cost £2 and the lemons £1. Given that John’s monthly income is £30 answer the following questions: What type of goods are oranges and lemons for John? What is the proportion to which John is willing to exchange Oranges for Lemons? Illustrate and solve graphically John’s utility maximization problem. If his income increases every month by £10, how will John’s consumption choice be affected? Illustrate graphically the income expansion path and the Engel curve for each good. How will an increase in the price of Lemons to £6 affect John’s optimal consumption choice? (John’s income is £30) Graph John’s demand curve for each good. Assume that John wins a voucher of £20, redeemable only in Oranges. How would this affect John’s utility?
