What is a common effect of hiring an additional worker according to VMPL?

The additional revenue generated by hiring an extra worker is associated with the concept of the Value of the Marginal Product of Labor (VMPL). This principle states that as firms employ more labor, each additional worker contributes to the production of goods and services. The VMPL reflects the additional revenue a firm earns from hiring one more worker, which generally leads to an increase in total output, provided that the firm operates within the domain of increasing marginal returns.

Hiring an additional worker contributes positively to revenue because the marginal product of labor typically increases production in the short run, leading to more goods or services being available for sale. As these products are sold in the market, they can generate additional income for the firm. This positive contribution to revenue is essential for firms as they evaluate labor decisions and optimize output levels to maximize profits.

The other options imply negative effects or neutral outcomes from hiring additional labor, which are less representative of typical economic behavior when firms can still operate efficiently and increase productivity with more workers. In general, the expectation is that hiring additional workers will lead to a beneficial impact on total revenue through increased production, making the selected answer valid and in alignment with economic principles.
