In the beginning of the clip Rachel tells Ross that she got her old job back at Ralph Lauren. Ross asks if she is still going to take the job in Paris (which she was offered in the previous episode) since she was hired back at her old job. Rachel says she still wants to go to Paris because when the people at Loui Vuitton found out Ralph Lauren wanted her back they decided to offer her more money. This clip is a good example of opportunity cost, which is the loss of potential gain from other alternatives when one alternative is chosen. If Rachel wouldn’t have chosen, the job in Paris she would have been missing out on more money than if she would have stayed. Since she is taking the job in Paris her opportunity cost is that she will have to leave her friends and family.
Thanks Kailey Werkheiser for the clip and the summary!
