(a)
To find the prices of good X and Y.

Explanation of Solution
The equation of Initial budget line is as follows:
The Standard Equation of budget line is as follows:
On comparing with the standard equation of budget line
Budget line: It is the graphical representation of all possible combination of two goods that consumer can afford within his limited income at given prices.
(b)
To find the number of units of good Y that can be purchased at point A.

Explanation of Solution
The number of units of good Y that can be purchased at point A is calculated as follows:
Therefore, the number of units of good Y produced at point A is 2 units.
Budget line: It is the graphical representation of all possible combination of two goods that consumer can afford within his limited income at given prices.
(c)
To find the number of units of good X that can be purchased at point E.

Explanation of Solution
The number of units of good X that can be purchased at point E is calculated as follows:
Budget line: It is the graphical representation of all possible combination of two goods that consumer can afford within his limited income at given prices.
(d)
To find the number of units of good X that can be purchased at point B.

Explanation of Solution
The number of units of good X that can be purchased at point B is calculated as follows:
At point B consumer spent his entire nominal amount of money on good Y and buy 2 units of good Y and using $100 gift certificate consumer can consume 1 unit of good X.
Budget line: It is the graphical representation of all possible combination of two goods that consumer can afford within his limited income at given prices.
(e)
To find the number of units of good X that can be purchased at point F.

Explanation of Solution
The number of units of good X that can be purchased at point F is calculated as follows:
At point consumer can consume 5 units of good X as buy spending his $400 income and additional $100 gift certificate, he is spending total of $500 on consumption of good X and consuming 5 units of good X.
Budget line: It is the graphical representation of all possible combination of two goods that consumer can afford within his limited income at given prices.
(f)
To find the number of units of good X that can be purchased at point F.

Explanation of Solution
Based on preferences consumer can rank his preference A, B, C and D.
Consumer will rank his preference as follow:
IC2 is the highest IC curve and gives more utility than IC1.
Budget line: It is the graphical representation of all possible combination of two goods that consumer can afford within his limited income at given prices.
(g)
To analyze whether good X is a normal good or inferior good.

Explanation of Solution
X is an inferior good because after getting gift card, he can spend gift card only on good X. Consumer is not splitting gift card on both the goods and using it to buy only X, which explains inferior nature of good X.
Budget line: It is the graphical representation of all possible combination of two goods that consumer can afford within his limited income at given prices.

- Answerarrow_forwardM” method Given the following model, solve by the method of “M”. (see image)arrow_forwardAs indicated in the attached image, U.S. earnings for high- and low-skill workers as measured by educational attainment began diverging in the 1980s. The remaining questions in this problem set use the model for the labor market developed in class to walk through potential explanations for this trend. 1. Assume that there are just two types of workers, low- and high-skill. As a result, there are two labor markets: supply and demand for low-skill workers and supply and demand for high-skill workers. Using two carefully drawn labor-market figures, show that an increase in the demand for high skill workers can explain an increase in the relative wage of high-skill workers. 2. Using the same assumptions as in the previous question, use two carefully drawn labor-market figures to show that an increase in the supply of low-skill workers can explain an increase in the relative wage of high-skill workers.arrow_forward
- Published in 1980, the book Free to Choose discusses how economists Milton Friedman and Rose Friedman proposed a one-sided view of the benefits of a voucher system. However, there are other economists who disagree about the potential effects of a voucher system.arrow_forwardThe following diagram illustrates the demand and marginal revenue curves facing a monopoly in an industry with no economies or diseconomies of scale.
