The full employment level of output in each year with the help of given information.
a.

Explanation of Solution
The full employment level of output in each year.
Given table,
Year | Output | |
1 | 8 | 950 |
2 | 6 | 1030 |
3 | 7 | 1033.5 |
4 | 5 | 1127.5 |
The full employment level of output is the output level at which all the available resources are used efficiently.
To calculate the full employment level of output, there is need to use the formula which is as follows:
Here,
Y is the actual output and u is the actual unemployment rate.
For year 1,
Therefore, in year 1 the full employment level of output is equal to $989.6.
Similarly, the full employment level of output in year 2, year 3, and year 4 can be calculated and the respective result is shown in table.
Year | Unemployment rate u | Natural rate of unemployment(%) | u-
| Actual output | Full employment level of output
|
1 | 0.08 | 0.06 | 0.02 | 950 | $989.6 |
2 | 0.06 | 0.06 | 0 | 1030 | $1030 |
3 | 0.07 | 0.06 | 0.01 | 1033.5 | $1054.6 |
4 | 0.05 | 0.06 | -0.01 | 1127.5 | $1105.4 |
b.
The growth rate of full employment level of output of year 2, 3, and 4 in two different ways.
b.

Explanation of Solution
The growth rate of full employment level of output is the ratio of change in full employment level of output to the full employment level of output that is,
For year 2, growth rate is:
The growth rate of full employment level of output with the help of previous solution is given below:
Year | Full employment level of output
| Growth rate
|
1 | 989.6 | - |
2 | 1030 | 0.04 |
3 | 1054.6 | 0.023 |
4 | 1105.4 | 0.048 |
For the second method, first calculate the change in unemployment rate, then the growth rate of output. And lastly use the Okun’s law, given as:
To calculate the full employment level of output. The tablegiven below represent the change in unemployment rate and growth rate of output.
Year | Unemployment rate u | Natural rate of unemployment(%) | Actual output Y | ||
1 | 0.08 | 0.06 | - | 950 | - |
2 | 0.06 | 0.06 | -0.02 | 1030 | 0.084 |
3 | 0.07 | 0.06 | 0.01 | 1033.5 | 0.003 |
4 | 0.05 | 0.06 | -0.02 | 1127.5 | 0.091 |
Now use the equation:
To find the full-employment level of output.
Write this equation as:
The following table represent the value of full-employment level of output.
Year | | ||
1 | - | - | - |
2 | -0.02 | 0.084 | 0.044 |
3 | 0.01 | 0.003 | 0.023 |
4 | -0.02 | 0.091 | 0.051 |
The comparison of full-employment level of output calculated by two different method is given below:
Year | Growth rate
| |
2 | 0.04 | 0.044 |
3 | 0.023 | 0.023 |
4 | 0.048 | 0.051 |
From the table, it is concluded that both the results are similar.

Political scientists Bethany Albertson and Adria Lawrence (2009) conducted an experiment in which they randomly assigned people to treatment and control groups to evaluate the effect of watching TV on a person’s information level. Those assigned to the treatment group were told to watch a specific television broadcast and were later asked questions related to what they watched. Those in the controlgroup were not shown the TV broadcast but were asked questions related to the material in the TV broadcast. The dataset contains the following variables: : Dummy variable which =1 if a person reads news and 0 otherwise. : interest in political affairs (not interested=1 to very interested=4) : years of education : female dummy variable (female=1; male=0) : family income in thousands of dollars : information level (low information level=1 to high information level=4) =1 if the…arrow_forwardProblem 2-Experiments/Randomized Control Trial Suppose you are interested in studying the effect of academic counselling on the years it takes for a student to obtain an undergraduate degree.
