Final answer:
Another way to increase productivity, besides producing more goods, is by decreasing the resources invested, which involves using them more efficiently due to better technology or processes. This can result in a rightward (or downward) shift in the supply curve. Improving product quality or increasing need can also lead to increased consumer demand, evidenced by a rightward shift in the demand curve.
Step-by-step explanation:
If increasing the number of goods produced is one way to increase productivity, another way to achieve this is by decreasing the resources invested (Option B). This doesn't necessarily mean reducing the quality or quantity of inputs but becoming more efficient in using them. Employing better technology or improved processes can lead to a decrease in the resources (like time, labor, and materials) required for production, thereby enhancing productivity. This improvement often manifests as a shift in the supply curve to the right or downward, indicating a lower price is necessary for firms to supply any given quantity. Such enhancements to productivity can also come from a reduction in input costs, such as less expensive materials, or advancements in technology leading to increased yields or more efficient production systems.
Additionally, while an improvement in product quality doesn't directly impact productivity, it can lead to an increase in consumer demand, illustrated by a rightward shift in the demand curve. An increase in the need for a product also reflects as a rightward shift in this curve. It is vital to note that raising prices, increasing market share, or lowering material quality do not inherently increase productivity.
