Final answer:
A frequent cause of business failure is poor management or unproductive workers, alongside fierce competition, and unexpected changes in market demand and supply affecting prices and costs.
Step-by-step explanation:
A common cause of business failure is poor management or workers who are not very productive, as well as tough domestic or foreign competition. For instance, market conditions might shift unexpectedly causing a reduction in the prices a business can charge for its products or an increase in the cost of inputs, which can lead to a business's decline. Moreover, business failures can be difficult for the workers and managers involved, but in a market-oriented economic system, they are sometimes a necessary part of the process of satisfying customers, keeping costs low, and innovating new products.
