Which of the following is NOT true about online marketplaces? [br]
In many ways, online marketplaces are the perfect business model. Since they facilitate transactions between independent suppliers and customers rather than take possession of and responsibility for the products or services in question, they have inherently low cost structures and fat gross margins. They are highly defensible once established, owing to network effects.
William and a team of researchers recruited dozens of small groups of friends for a study. They gave participants intelligence and personality tests and then asked each subject to answer 30 common-knowledge questions — such as "What’s the name of a precious gem?" — as rapidly as possible. Participants also rated their friends’ charisma and social skills. The researchers found that individuals who answered the questions more quickly were perceived to be more charismatic — regardless of their IQ, knowledge, or personality.
