a
To plot:
Graphical representation of production frontier.
a

Explanation of Solution
The utility function is given by as-
The budget line is given as:
With the help of Langraingian expression this problem can be explained as:
Taking the differentials w.r.t x,y and
Demand for x is given by:
Demand for y is given as:
His or her demand for x and y depends on relative prices of these value.

Introduction:
Utility is the amount of satisfaction derived for consumption of goods or services. It is usually measured in utils.
b)
To find:
Quantity of x and y to be produced.
b)

Explanation of Solution
The total available goods are 1000. From the equilibrium condition is given as-
Now put this value of x in the budget equation:
Now put this value of x in the budget equation:
Here
The total endowment is 1000. So, y = 500 and x = 500
Introduction:
Indifference curve is a curve which represents combination of goods which gives equal satisfaction.
c)
To know:
RPT and price ratio of
c)

Explanation of Solution
For this
The equation shows the pareto optimal allocation. It is given that
y = 500 and x = 500
The price ratio can be calculated as follows:
This expression shows pareto efficient condition.
Introduction:
Marginal Rate of technical substitution is the rate at which one factor of input can be substituted for another input, output remaining same. It shows efficiency of inputs for productivity.
Indifference curve is a curve which represents combination of goods which gives equal satisfaction.
d)
To find:
Price ratio and MRS.
d)

Explanation of Solution
Suppose total amount of the product be allocated between x and y with respect to x=600 and y = 400. The given utility function is given as:
So, the MRS is given as:
It is known that marginal rate of substitution is equal to price ratio = 0.67
Introduction:

- 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. In the short and long run, MC = ATC. a. Calculate the values of profit, consumer surplus, and deadweight loss, and illustrate these on the graph. b. Repeat the calculations in part a, but now assume the monopoly is able to practice perfect price discrimination.arrow_forwardThe projects under the 'Build, Build, Build' program: how these projects improve connectivity and ease of doing business in the Philippines?arrow_forward
