We overvalue the things we own. This is fine when it’s a family keepsake or memento – but how does this influence decisions we make about our homes, investments, and more?

"Both the Boston Red Sox and the Chicago White Sox had rather mediocre seasons last year. The Red Sox have some exciting young hitters but a lack of decent pitchers. The White Sox have almost the exact opposite problem … So the argument was to put a Chicago White Sox’ message board: would they trade their great young pitcher Chris Sale for two excellent and even younger hitters from the Red Sox, Xander Bogaerts and Mookie Betts?" From John Auther’s 2015 Financial Times article: "Investors psyched by the endowment effect".
