What are diminishing marginal returns?

Diminishing marginal returns is a concept in economics that explains the decrease in the marginal output of a production process as more of a single input (e.g., labor) is added, keeping other inputs (e.g., capital) constant. It implies that after a certain point, adding more of a single input will eventually contribute less and less to the total output.

Let's consider a factory that produces widgets. When the factory starts production, it has a certain amount of machines and labor. As more workers are hired, the total output of widgets increases because each worker can operate a machine or contribute individually to the production process. However, after a certain point, adding more workers becomes less effective. This is because the machines and other resources available in the factory cannot be used effectively by all workers, resulting in a decrease in their productivity. As a result, the marginal output (additional widgets produced per additional worker) starts to decrease. This phenomenon is called diminishing marginal returns. It can be applied to other inputs as well, such as capital, materials, and technology.

To better understand diminishing marginal returns, let's create a graph to visualize the relationship between the number of workers (input) and the total output (widgets produced). 1. On the X-axis, represent the number of workers 2. On the Y-axis, represent the total output of widgets 3. Draw a curve that initially rises steeply as more workers are added, reaches a peak, and then starts to flatten and eventually decline. This graph represents the concept of diminishing marginal returns. At first, as more workers are added, the total output increases at an increasing rate. However, after a certain point, the rate of increase in output starts to decrease, and the curve flattens, illustrating that adding more workers is becoming less effective in increasing output.
