Amonopoly, unlike a perfectly competitive firm, has some market power. thus, it can raise its price, within limits, without quantity demanded falling to zero. the main way monopolies retain their market power is through barriers to entry, which prevent other companies from entering monopolized markets and competing for customers. consider the market for computer technology. patents are granted to inventors of products or processes for a certain number of years to encourage innovation. without patents, research and development needed to improve computer technology are unlikely to occur, as nothing would then prevent other firms from stealing ideas and copying products. which of the following best explains the barriers to entry that exist in this scenario?

exclusive ownership of a necessary resource

legal barriers

increasing returns to scale

Who is better at multi-tasking? in business, employees are often asked to perform a complex task when their atten-tion is divided (i.e., multi-tasking). human factors (may 2014) published a study designed to determine whether video game players are better than non–video game play-ers at multi-tasking. each in a sample of 60 college stu-dents was classified as a video game player or a non-player. participants entered a street crossing simulator and were asked to cross a busy street at an unsigned intersec-tion. the simulator was designed to have cars traveling at various high rates of speed in both directions. during the crossing, the students also performed a memory task as a distraction. two variables were measured for each student: (1) a street crossing performance score (measured out of 100 points) and (2) a memory task score (measured out of 20 points). the researchers found no differences in either the street crossing performance or memory task score of video game players and non-gamers. “these results,” say the researchers, “suggest that action video game players [and non-gamers] are equally susceptible to the costs of dividing attention in a complex task”

The following costs were incurred in may: direct materials $ 44,800 direct labor $ 29,000 manufacturing overhead $ 29,300 selling expenses $ 26,800 administrative expenses $ 37,100 conversion costs during the month totaled:
