Question 9. Question : In cities with rent controls, the actual rents paid can be higher than the legal maximum. One explanation for this is
rent control laws are so complicated that landlords and tenants may not be aware of what the legal price is.
landlords are allowed to charge more than the legal maximum on some apartments so long as they charge less on others.
because there is a shortage of apartments, tenants often are willing to pay rents higher than the law allows.
the legal penalty landlords face for charging more than the legal maximum rent is less than the revenue earned by charging their tenants more than the maximum rent.

Both concepts explain why marginal cost increases after some point but diminishing marginal returns applies only in the short run when there is at least one fixed factor, while diseconomies of scale applies in the long run when all factors are variable. Both concepts explain why average total cost increases after some point but diminishing marginal returns applies only in the short run when there is at least one fixed factor, while diseconomies of scale applies in the long run when all factors are variable. Diminishing marginal returns which applies only in the short run, when at least one factor is fixed, explains why marginal cost increases, while diseconomies of scale which applies in the long run, when all factors are variable, explains why average cost increases. Diminishing marginal returns which applies only in the short run, when at least one factor is fixed, explains why average variable cost increases, while diseconomies of scale which applies in the long run, when all factors are variable, explains why average total cost increases. Question 10. Question : The law of diminishing marginal returns explains why the average total cost and marginal cost curves are U-shaped in the short run. explains why the average total cost, average fixed cost and the marginal cost curves are U-shaped in the short run. causes average total costs to rise at a decreasing rate as output increases. causes the difference between average total cost and average variable cost to get smaller as output increases.

KAPLAN MT445 UNIT 6 QUIZ Question 1. Question : One of your classmates asserts that advertising, marketing research, and brand management are redundant expenditures because a firm can obtain the same information by simply looking at what customers are already buying. Which of the following is not a response you might offer her? Conducting market research is a good way for firms to keep abreast of changing consumer tastes and preferences. Advertising and brand management allow a firm to create an entry barrier which will insulate the firm from competition and from undertaking further product innovations. Marketing research could allow a firm to identify new market opportunities and at least, in the short run, a firm can make a profit supplying products to this market segment. If a firm successfully manages its brand, customers become less price sensitive as they perceive fewer substitutes for the firm's brand. Question 2.
