Now Playing: 12-06-13 Marketplace Money - Money and psychology

This weekend on Marketplace Money, host Carmen Wong Ulrich explores the psychology of self-control leading up to the time of year when people make resolutions – financial and otherwise. She’s joined by Maria Konnikova, author of the forthcoming book “Mastermind: How To Think Like Sherlock Holmes” to talk about willpower, determination and rewards. CBS News Business Analyst Jill Schlesinger also joins the program to help answer listeners’ questions about personal finance, plus Carmen digs into the topic of financial gifts in a special “Lightning Round” of Q&As. Also, we check back in with a former guest who had $1,000 riding on a weight loss competition to see what the outcome was.
