Economist John List has shown that the so-called endowment effect tends to be lower among people who often

A) buy things for resale.
B) buy things for personal long-term use.
C) produce things for themselves.
D) value their possessions.

John List's research indicates that the endowment effect, which is the tendency for people to ascribe more value to things merely because they own them, is less pronounced among individuals who frequently buy items with the intention of reselling them. This is because such individuals are more accustomed to thinking about goods in a market context, making them more objective about the value of possessions.
