Final answer:
Here to There and Zippy exemplify forbearance, a form of implicit collusion where businesses adjust their rates in response to each other's pricing, without an explicit agreement, to maintain similar rates and avoid a price war.
Step-by-step explanation:
The behavior of 'Here to There' and 'Zippy' constitutes forbearance, which is a type of implicit collusion. These companies engage in a form of non-cooperative behavior, where, without an explicit agreement, they monitor each other's pricing and adjust their rates to maintain a similar pricing structure. This is not explicit collusion, where there would be a negotiated agreement between the companies to set prices or market shares. Unlike the airline scenario provided, where predatory pricing is used to push out competition, the ride-sharing services are not acting aggressively to eliminate competition but rather are maintaining a status quo to prevent a price war between them.
In the airline example, a large incumbent firm attempts to drive out a new competitor by slashing prices, a tactic known as predatory pricing, which differs from the behavior of Here to There and Zippy. In comparison, Greyhound Lines, Inc. and Trailways Transportation System would prefer a broader market definition to present a less concentrated market scenario to regulators, emphasizing competition from a variety of other intercity transportation modes.
