Quizplus · Accepted Answer

Barriers to entry are factors that make it difficult for new firms to enter a market. Patents and copyrights protect intellectual property, preventing others from using it without permission. Control over essential inputs means a company has exclusive access to materials necessary for production, limiting competition. Economies of scale refer to the cost advantages that enterprises obtain due to their scale of operation, with cost per unit of output decreasing with increasing scale, making it harder for smaller competitors to compete.
