Final answer:
Factors influencing a company's footwear production reject rate include wages, union demands, machinery usage, comparative advantage, and production choices for labor and capital use, all affecting production efficiency and quality.
Step-by-step explanation:
The reject rate at a company's footwear production facilities can be influenced by multiple factors. When unions demand higher wages, firms may opt for production methods that rely more on physical capital and less on labor to increase labor productivity. For instance, the firm might change combinations of labor and machinery usage, such as reducing the number of hours paid to labor and increasing the number of machines, especially if the wage rises significantly, say from $16 an hour to $24 an hour, to minimize costs and meet production demands efficiently. Furthermore, such production choices have implications on the employment level, as opting for more machinery could lead to hiring fewer workers.
From an economic perspective, focusing on comparative advantage, as illustrated by the shifting of workers in the United States and Mexico, can result in more efficient production distribution, and this can potentially influence the quality of production. Hence, all these factors interact in determining the final reject rate and overall production efficiency.
