ABSTRACT
An economist (John) loses his keys while walking across a dark parking lot. His friend (Jane) happens upon him some time later.
Jane: Hi John! What are you looking for? John: I lost my keys somewhere in this parking lot. Jane: Did you lose them under one of these streetlights? John: No, I checked those areas twice already. Jane: So why are you still looking under the streetlights? John: Because that’s where the light is!
