The time period for project LA should be equated with the time period of project IN and CO to compare the present worth. The common time period for all the projects is 12 years. The present worth of project LA (PWL) can be calculated as follows:

PWL=AWL((1+i)n−1i(1+i)n)=−136,933.88((1+0.1)12−10.1(1+0.1)12)=−136,933.88(3.138428−10.1(3.138428))=−136,933.88(2.1384280.313843)=−136,933.88(6.813687)=−933,024.6

The present worth of the project LA is -$933,024.6.

The time period for project IN should be equated with time period of project LA and CO to compare the present worth. The common time period for all the projects is 12 years. The present worth of project LA (PWL) can be calculated as follows:

PWI=AWI((1+i)n−1i(1+i)n)=−227,764.2((1+0.1)12−10.1(1+0.1)12)=−227,764.2(3.138428−10.1(3.138428))=−227,764.2(2.1384280.313843)=−227,764.2(6.813687)=−1,551,913.97

The present worth of the project IN is -$1,551,913.97.

The time period for project CO should be equated with time period of project LA and IN to compare the present worth. The common time period for all the projects is 12 years. The present worth of project CO (PWC) can be calculated as follows:

PWC=AWC((1+i)n−1i(1+i)n)=−140,000((1+0.1)12−10.1(1+0.1)12)=−140,000(3.138428−10.1(3.138428))=−140,000(2.1384280.313843)=−140,000(6.813687)=−953,916.18

The present worth of the project CO is -$953,916.18.

Answer

M” method Given the following model, solve by the method of “M”. (see image)

As 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.

PWC=AWC((1+i)n−1i(1+i)n)=−140,000((1+0.1)12−10.1(1+0.1)12)=−140,000(3.138428−10.1(3.138428))=−140,000(2.1384280.313843)=−140,000(6.813687)=−953,916.18

The present worth of the project CO is -$953,916.18.

Since the present worth of the project LA is greater than the other two project, select the project LA.

Expert Solution

Explanation of Solution

Table -1 shows the cash flow of different models.

Table -1

Models	LA	IN	CO
First cost (C)	-150,000	-900,000
AOC (MO) per year	-95,000	-60,000	-140,000
Salvage value (SV)	25,000	300,000
Time period (n)	4	6	2
Interest (i)	10%	10%	10%

The equivalent annual worth of project LA (AWL) can be calculated as follows:

AWL=C(i(1+i)n(1+i)n−1)+MO+SV(i(1+i)n−1)=−150,000(0.1(1+0.1)4(1+0.1)4−1)−95,000+25,000(0.1(1+0.1)4−1)=−150,000(0.1(1.4641)1.4641−1)−95,000+25,000(0.11.4641−1)=−150,000(0.146410.4641)−95,000+25,000(0.10.4641)=−150,000(0.315471)−95,000+25,000(0.215471)=−47,320.65−95,000+5,386.775=−136,933.88

The annual worth of the project LA is -$136,933.88.

The equivalent annual worth of model IN (AWI) can be calculated as follows:

AWI=C(i(1+i)n(1+i)n−1)+MO+SV(i(1+i)n−1)=−900,000(0.1(1+0.1)6(1+0.1)6−1)−60,000+300,000(0.1(1+0.1)6−1)=−900,000(0.1(1.771561)1.771561−1)−60,000+300,000(0.11.771561−1)=−900,000(0.17715610.771561)−60,000+300,000(0.10.771561)=−900,000(0.229607)−60,000+300,000(0.129607)=−206,646.3−60,000+38,882.1=−227,764.2

The annual worth of the model IN is -$227,764.2.

Since the annual worth of the project LA is greater than the other two project, select the project LA.

The present worth of the project LA is -$933,024.6.

The time period for project IN should be equated with time period of project LA and CO to compare the present worth. The common time period for all the projects is 12 years. The present worth of project LA (PWL) can be calculated as follows:
