Why do people and businesses make certain decisions about their money? What drives them to buy or sell stocks, real estate, or something else of value? In this module, we explore behavioral factors that drive many business decisions. We examine different theories on why people make the choices they make, and we compare the effects of psychological, cognitive, emotional, cultural and social factors on the economic decisions of individuals and institutions and how those decisions vary from those implied by classical theory. Students will complete several quizzes online, and also participate in an online group discussion.
