This course introduces students to the concept of behavioural finance and its impact on financial markets and decision making. We will introduce and investigate behavioural traits, including over confidence, confirmation bias and loss aversion and discuss how these traits can function as obstacles to the use of traditional finance tools as studied in other courses. We will also consider how best to avoid the pitfalls inherent in financial decision making. At the end of this course, students will understand the nature and impact these psychological factors have on important business decisions.
