Single-factor productivity:
If we produce only one product, the numerator can be either the total pieces of
the product or the total $ value of the product. If we produce several products,
the numerator is the total $ value of all products.
The denominator can be the pieces of input or the total $ value of input.
Example: Single Factor Productivity
Labor Productivity:
Quantity (or value) of output / labor hrs
Quantity (or value) of output / shift
Machine Productivity:
Quantity (or value) of output / machine hrs
Energy Productivity:
Quantity (or value of output) / kwh
Capital Productivity
Quantity (or value) of output / value of input
All-factor productivity
All-factor productivity:
If we produce only one product, the numerator can be either the total pieces of
product or total $ value of the product.

Exercise: Productivity
1. A company that makes shopping carts for supermarkets recently purchased new equipment,
which reduced the labor content needed to produce the carts. Information concerning the old
system (before adding the new equipment) and the new system (after adding the new
machines) includes:
Old System New System
Output/hr 80 84
Workers 5 4
Wage $/hr 10 10
Machine $/hr 40 50
a) Compute labor productivity for both the Old System and the New System (in every possible
way).
b) Compute AFP productivity for both the Old System and the New System.
c) Suppose production with old equipment was 30 pieces of cart A at a price of $100 per cart, and
50 pieces of cart B at a price of $120. Also suppose that production with new equipment is 50
pieces of cart A, at a price of $100 per cart, and 34 pieces of cart B at a price of $120. Compare
all-factor productivity for the old and the new systems.

Exercise: Productivity
A cable manufacturing company produces two types of cables from same raw materials;
wire and plastic resins. To produce one meter first type cable 100 gm resin and 0.3 kg
wire are required. Whereas, 150 gm resin and 0.4 kg wire are required to produce one
meter of the second type cable. Cost of resin and wire is Tk.80/Kg and Tk.100/Kg
respectively. The company can produce 60000 meter first type and 40000 meter second
type cable per month by using 200 labors. Average wage of each labor is Tk.600 per day,
and overhead cost is 3 million taka per month. To set up the machine 60 million taka is
invested on it. Life of the machine is 5 years. Price of the first and second type cable is
Tk.300/meter and Tk.350/meter respectively. Consider 25 working days make a month.
Compute labor, material, machine, overhead and multi factor productivity for both
first and second type cable and interpret the result.
Compute Labor productivity for first type cable (in every possible way) and All factor
productivity for the first type Cable and interpret the result. (In daily basis)
