There are two phenomena in behavioral finance and economics which are seemingly unrelated and have been studied separately; overconfidence and ambiguity aversion. In this paper we are trying to link these two phenomena providing a theoretical foundation supported by evidence from an experimental...

Overconfident behavior, the excessive willingness to bet on one’s performance, may be driven by optimistic beliefs and/or ambiguity attitudes. Separating these factors is key for understanding and correcting overconfident behavior, as they may call for different corrective actions. We present...

The main objective of this paper was to establish which behavioural finance biases are associated with a certain level of risk tolerance and investor personality. Furthermore, the study aimed to indicate how these behavioural finance biases can influence investment decisions. Since behavioural...

Why are men more risk tolerant than women, and why do they invest more than women? I test whether identity stereotypes help explain this heterogeneity. I manipulate identity in a controlled environment by priming its salience to subjects. Men whose identity is primed take on more risk, and...

We document that an internal locus of control can be hindering in financial market situations, where short-term outcomes are determined by chance. The reason is that internally controlled individuals may tend to (over-)react to random outcomes. Our evidence is based on an experiment in which...

We show that household heads with a strong internal economic locus of control are more likely to hold equity and hold a larger share of equity in their investment portfolio. This relation holds when we control for economic preferences and possible confounders such as financial literacy,...

Psychology considers self-control failure, i.e., the inability to resist certain behaviors and impulses when seeking to achieve future goals as a major human pathology. The finance literature models and applies self-control failure to explain time-inconsistent behavior such as under-saving and...
