How Technological Change Affects the Per-Worker Production Function

Technological advancements are the bedrock of economic growth, profoundly impacting how we produce goods and services. Understanding this impact requires examining its effect on the per-worker production function – a crucial concept in economics that describes the relationship between the inputs a worker uses (like capital and technology) and the output they produce. This article will delve into how technological change alters this function, exploring both the positive and negative implications.

Understanding the Per-Worker Production Function

The per-worker production function essentially shows how much output each worker can generate given a specific level of capital and technology. It's typically represented graphically as a curve, where the quantity of capital per worker is on one axis and the output per worker is on the other. The shape of the curve reflects diminishing marginal returns: adding more capital per worker initially leads to significant increases in output, but eventually, the effect diminishes.

The Impact of Technological Change

Technological change shifts this production function. It does so primarily in two ways:

1. Technological Progress as a Shift: This is the most common and significant effect. New technologies fundamentally alter the production process, allowing workers to produce more output with the same amount of capital or the same output with less capital. This is represented by an upward shift of the entire production function curve. For instance, the introduction of the assembly line dramatically increased the output per worker in manufacturing, shifting the production function upwards. Similarly, the advent of computer-aided design (CAD) and computer-aided manufacturing (CAM) further boosted productivity.

2. Technological Change as a Change in the Production Function's Shape: While shifts are common, technological change can also alter the shape of the function itself. Certain technologies may lead to increasing returns to scale – meaning the output increases proportionally more than the input increase. This could lead to a steeper slope at certain points on the curve. Conversely, other technologies might lead to a flattening of the curve at higher levels of capital per worker, indicating diminishing returns setting in earlier. The specific impact depends on the nature of the technological advancement and how it interacts with existing production processes.

Examples of Technological Impacts:

• Automation: Robots and automated systems replace human labor in various tasks, potentially leading to higher output per remaining worker but also job displacement. The overall effect on the production function depends on the net impact of increased efficiency and reduced workforce.

• Information and Communication Technologies (ICT): The internet, computers, and mobile devices have revolutionized communication, data processing, and collaboration, significantly boosting productivity across many sectors. This translates to an upward shift of the per-worker production function.

• Biotechnology: Advances in genetics and biotechnology are revolutionizing agriculture and medicine, leading to increased yields and improved healthcare outcomes. These innovations directly increase output per worker in these sectors.

Negative Aspects and Challenges:

While technological progress is generally beneficial, it also presents challenges:

• Job displacement: Automation and technological advancements can lead to job losses in certain sectors, requiring workforce retraining and adaptation.

• Income inequality: The benefits of technological progress might not be equally distributed, leading to widening income inequality between those who own or control the new technologies and those whose jobs are displaced.

• Environmental impact: Technological advancements often consume energy and resources, potentially exacerbating environmental concerns.

Conclusion:

Technological change is a powerful driver of economic growth, fundamentally altering the per-worker production function. While it predominantly leads to an upward shift in the function, representing increased productivity, its impact is multifaceted and complex. Understanding the nuances of how specific technologies affect the production function is crucial for policymakers and businesses to manage the challenges and harness the opportunities presented by technological progress, ensuring inclusive and sustainable economic growth.
