What does the monkey experiment teach us about finance?

Sorry, this is a lot to read, but it's the real answer!

  We hate to lose any small amount of money, because to us, that could be a lunch or dinner. Even though it's not a lot, we still act as though it is.

Explanation:

One more before we flip the challenges into solutions, having to do with monkeys and apples. No, no, no, this is a real study and it's got a lot to do with behavioral economics. One group of monkeys gets an apple, they're pretty happy. The other group gets two apples, one is taken away. They still have an apple left. They're really mad. Why have you taken our apple? This is the notion of loss aversion. We hate losing stuff, even if it doesn't mean a lot of risk. You would hate to go to the ATM, take out 100 dollars and notice that you lost one of those $20 bills. It's very painful, even though it doesn't mean anything. Those 20 dollars might have been a quick lunch. So this notion of loss aversion kicks in when it comes to savings too, because people, mentally and emotionally and intuitively frame savings as a loss because I have to cut my spending.
