Productivity Measures - Partial Productivity, Total Productivity, Total Factor Productivity.

Main Ideas: Three Types of Productivity Measures

The video explains that productivity measures are commonly classified into three categories:

1. Partial Productivity Measures (PPM)
2. Total Productivity Measures (TPM)
3. Total Factor Productivity Measures (TFP)

1) Partial Productivity Measures (PPM)

Definition / Formula

• Partial productivity = Total output ÷ individual input
• The measure focuses on one input factor at a time.

Types of PPM (as described)

1. Labor productivity
   • Labor productivity = Total output ÷ Labor input
   • Labor input is measured in man-hours.
2. Capital productivity
   • Capital productivity = Total output ÷ Capital input
3. Material productivity
   • Material productivity = Total output ÷ Material input
4. Energy productivity
   • Energy productivity = Total output ÷ Energy input

Key Disadvantage

• Overemphasis on one input factor
• Other inputs may be underestimated or ignored
• Therefore, PPM cannot represent overall firm productivity

2) Total Productivity Measures (TPM)

Definition / Formula

• Total productivity = Total tangible output ÷ Total tangible input

How “Total Tangible Output” is Constructed

Total tangible output includes the measurable/monetary value of:

• Value of finished goods produced
• Value of partial units produced
• Dividends from securities
• Interest and other income

How “Total Tangible Input” is Constructed

Total tangible input equals the measurable/monetary value of:

• Human input
• Material input
• Capital
• Energy
• Other inputs used

Meaning of “Tangible”

• “Tangible” refers to measurable items.
• Both output and inputs must be expressed in a common measurement unit.

Best Method to Standardize Units (as stated)

• Express output and inputs in rupee value.

Adjustment for Time Comparison (Base-Year Adjustment)

Productivity indices should be:

• Adjusted to a base year
• Stated in base-year rupee value

This is done via deflators to remove price-change effects across years.

Deflator Computation (as stated)

• Deflator value = (Current year price) ÷ (Base year price)

Features / Benefits of TPM (as listed)

1. Gives firm-level and also detailed unit-level productivity indices
2. Helps find performance and productivity of operational units
3. Helps plan, evaluate, and control
4. Provides important information for strategic decisions like:
   • Expansion (EXP)
   • Phasing out decisions

3) Total Factor Productivity (TFP)

Definition / Formula

• TFP = Net output ÷ (Labor + Capital inputs)
  • i.e., net output divided by the summation of labor and capital inputs

Key Point About Data Approach

• It uses a value-added approach
• Data from company records is relatively easy to obtain

Key Limitation (as stated)

• No consideration for material and energy inputs
• It is difficult to relate the value-added approach to production efficiency

Advantages and Limitations Across All Measures (Overall Comparison)

PPM

• Advantage: Easy to understand and calculate; helps pinpoint improvements
• Limitation: Can be misleading if used alone (doesn’t capture overall impact)

TPM

• Advantage: More accurate overall picture; related to total costs; considers all quantifiable outputs and inputs
• Limitation: Difficulty in obtaining the required data; may require a special data collection system

TFP

• Advantage: Company records often provide the needed data; uses a value-added approach
• Limitation: Ignores material and energy; harder to tie value-added results to production efficiency
