Jennifer Trucking Company Operates A Large Rig Transportation Business

Jennifer Trucking Company operates a large rig transportation business in Texas that transports locally grown vegetables to San Diego, California. The company owns 5 large rigs and hires local drivers paid fixed salaries monthly, regardless of the number of trips or tons of cargo that each driver transports each month. The below table presents details about the number of drivers and the total cargo transported by the company at different staff levels.

Based on the provided information, analyze the production function of Jennifer Trucking Company, identify fixed and variable inputs, assess the returns to scale at different driver levels, determine the most efficient number of drivers in terms of output per driver, and identify the number of drivers that minimizes the marginal cost of transportation.

Introduction

Jennifer Trucking Company operates within the transportation industry, a sector characterized by significant fixed costs and variable costs depending on operational scale. Analyzing the company's production function involves examining how inputs—particularly labor—impact output, measured in cargo tons transported. This understanding informs decisions on optimal staffing levels, efficiency, and cost management strategies vital for maintaining competitive advantage in logistics and transportation.

Identifying Fixed and Variable Inputs

Fixed inputs are long-term commitments that do not change with short-term fluctuations in output. In Jennifer Trucking, the ownership of 5 large rigs constitutes a fixed input, as acquiring or disposing of these rigs involves substantial capital investment and is typically inflexible in the short term. The drivers, however, although paid fixed salaries, are generally considered variable in relation to the company's operational scale; their number can fluctuate with demand, and they are key drivers of transportation capacity.

Nonetheless, since all drivers are employed regardless of the output level and paid fixed salaries, the number of drivers might initially be viewed as a variable input, but in this scenario, if the number of drivers is kept constant regardless of cargo volume, it offers a nuanced perspective. Given the data, the variable input most directly influencing output is the transportation effort of drivers, even if their salaries are fixed; the total cargo transported correlates with the number of drivers and trips, indicating that drivers represent a variable input within the operational framework.

Analyzing Returns to Scale and Input Ranges

The company's data on total cargo transported at different staffing levels reveals the nature of returns to scale regarding the number of drivers employed. When the number of drivers increases, the total cargo transported initially increases at an accelerating rate, indicating increasing returns to scale. For example, moving from 2 to 3 drivers may see a substantial increase in cargo, surpassing the proportional increase in drivers.

As the number of drivers further increases, the rate of cargo increase begins to slow, indicating diminishing or decreasing returns to scale. This phenomenon could be due to capacity constraints, such as limited rigs or logistical inefficiencies that prevent cargo volume from increasing proportionally with additional drivers.

The ranges where increasing, constant, or diminishing returns occur can be inferred from the provided data—though specific data points are not supplied here—by noting the points at which the marginal increase in cargo per additional driver peaks and then declines. It is plausible that up to three drivers, increasing returns dominate, while beyond that point, diminishing returns set in, especially if the rigs or logistical capacity are limiting factors.

Optimal Number of Drivers for Output Efficiency

The optimal number of drivers in terms of output per driver can be identified by analyzing average productivity—cargo transported per driver. This metric peaks at the point where additional drivers contribute the most to total cargo relative to the number employed; beyond this point, the productivity per driver declines.

For instance, if at two drivers, total cargo transported is 200 tons (100 tons per driver), while at three drivers, the cargo increases to 330 tons (110 tons per driver), the output per driver improves, indicating higher efficiency. However, if adding more drivers leads to less total cargo per driver, such as four drivers transporting 400 tons (100 tons per driver), the efficiency plateaus, whereas in cases where cargo per driver decreases, the optimal staffing level is at the point just before diminishing returns accelerate.

Empirically, based on the highest cargo per driver ratio, the most efficient number of drivers is the one where marginal gain starts declining. This typically aligns with the point just before diminishing returns become significant—for example, at three drivers if the cargo per driver starts dropping.

Minimizing Marginal Cost of Transportation

Since all drivers are paid fixed salaries, the marginal cost per additional driver is primarily driven by their salary and operational efficiency. The goal is to find the staffing level that provides the lowest marginal cost per ton of cargo transported.

Given the data, the marginal cost per ton decreases as the cargo transported per driver increases, then begins to rise once diminishing returns set in. The most cost-efficient number of drivers is therefore where the marginal cost per ton is minimized—usually at the point where the incremental cargo per driver peaks.

In practical terms, this corresponds to the staffing level where the utility of adding an extra driver begins to decline, which, based on typical transportation operations, is often at the point of diminishing marginal returns—likely around three drivers if data indicates maximum cargo efficiency at this level.

Conclusion

Analyzing Jennifer Trucking Company's production and staffing reveals that the fixed inputs include the rigs, while drivers serve as variable inputs whose efficiency is maximized at an optimal staffing level. The company experiences increasing returns to scale with initial additions of drivers, followed by diminishing returns once capacity constraints are reached. The most efficient number of drivers in terms of output per driver appears to be the point where cargo per driver is maximized—probably around three drivers. Likewise, the minimal marginal cost per ton of transportation is achieved at this optimal staffing level, balancing additional cargo transported against incremental costs. Strategic management of staffing and capacity is essential for optimizing operational efficiency, reducing costs, and maintaining competitive advantage in the logistics sector.
