Final answer:
The impact of high quality on competitive advantage is not exclusively two-fold; it is affected by various factors like education, knowledge base, and economies of scale. Examples of competitive industries include technology and airlines.
Step-by-step explanation:
The statement concerning the impact of high quality on competitive advantage being two-fold is false. Competitive advantage comes from various factors that contribute to different levels of productivity. For example, factors like the education of workers, the knowledge base of engineers and scientists, specialized segments of a value chain, and economies of scale can be crucial in establishing a comparative advantage for one economy over another.
Regarding evidence of serious competition between firms in an industry, look for signs such as aggressive marketing campaigns, price wars, and the rapid introduction of new products. Two industries where intense competition is evident include the technology sector, particularly in smartphones and personal computers, and the airline industry, where carriers compete fiercely on price, routes, and customer service.
