Answer:
The total efficiency units of labor will decrease because the number of employed workers is less.
Step-by-step explanation:
We are asked to compare the total efficiency units of labor from two different periods in an economy. Efficiency units of labor can be calculated by taking the number of workers in the economy and multiplying that with the efficiency of each one.
Since we are told that the unemployment rate increases between period 1 and 2, we can say that the total efficiency units of labor is going to decrease because the total number of workers decrease due to the increase in unemployment numbers.
