Partial Productivity

Sample Solution

   

Inputs Used by a Homebuilder to Build Homes

The inputs used by a homebuilder to build homes can be divided into two categories: labor and non-labor inputs.

Labor Inputs

The labor inputs used by a homebuilder include:

• Construction workers (e.g., carpenters, plumbers, electricians, roofers, etc.)
• Construction supervisors
• Project managers

• Architects
• Engineers

Non-Labor Inputs The non-labor inputs used by a homebuilder include:

• Land
• Building materials (e.g., lumber, concrete, shingles, windows, doors, etc.)
• Construction equipment (e.g., excavators, bulldozers, cranes, etc.)
• Permits and fees

Examples of Partial Productivity Statistics

• Partial productivity of construction workers: This could be measured as the number of square feet of framing completed by a construction worker in a day.
• Partial productivity of construction equipment: This could be measured as the number of cubic yards of dirt excavated by an excavator in an hour.

Factors that Can Reduce Partial Productivity

• Poorly trained or inexperienced workers
• Faulty or outdated equipment
• Inefficient work processes
• Bad weather
• Material shortages

Factors that Can Improve Partial Productivity

• Training and development for workers
• Investing in new and efficient equipment
• Streamlining work processes
• Using project management software to track progress and identify bottlenecks
• Partnering with reliable suppliers to ensure a steady supply of materials

Calculating the Overall Productivity of a Homebuilder The overall productivity of a homebuilder can be calculated using a variety of methods. One common method is to use a total factor productivity (TFP) measure. TFP measures the change in output relative to the change in all inputs. To calculate TFP, first divide the output of the homebuilder (i.e., the number of homes built) by the total cost of inputs (i.e., the cost of labor, materials, and equipment). This will give you a measure of the homebuilder's efficiency. Next, compare the homebuilder's efficiency to the efficiency of other homebuilders in the industry. If the homebuilder is more efficient than other homebuilders, then it has a higher TFP. Conclusion By understanding the inputs that are used to build homes and the factors that can affect productivity, homebuilders can identify opportunities to improve profitability. Here are some specific examples of how a homebuilder could improve the partial productivity of some particular inputs:

• Construction workers: Provide workers with training on new tools and techniques. Invest in ergonomic equipment to reduce fatigue and injuries.
• Construction equipment: Use GPS technology to optimize the movement of equipment on the construction site. Rent or lease equipment instead of buying it outright to reduce maintenance and depreciation costs.
• Building materials: Negotiate volume discounts with suppliers. Order materials in bulk to reduce shipping costs.
• Permits and fees: Streamline the permitting process by working closely with local government officials. Use electronic permitting systems to reduce paperwork and delays.

By improving the partial productivity of its inputs, a homebuilder can reduce its overall costs and improve its profitability.
