This study attempts to group investors (individuals and professionals) into different segments based on their psychological biases and personality traits and, then, to examine whether, and how, these biases and traits drive their investment behaviour. The behavioural finance literature suggests...

Economic theory suggests that households should invest their financial wealth in a combination of cash and a well-diversified equity portfolio. Yet, many households' equity investments are strongly concentrated in a few assets. Attempts to explain this discrepancy have included low levels of...

This paper explores the relationship between risk attitude and asset diversification in household portfolios. We first examine the impact of manifested risk aversion on the total number of distinct assets held in a portfolio (naive diversification). The second part of the paper focuses on a more...

We conduct a randomized controlled trial to understand how a web-based retirement saving calculator affects workers' retirement-savings decisions. In both conditions, the calculator projects workers' retirement income goals. In the treatment condition, it also projects retirement income based on...

I show that household investment decisions depend on the manner in which information is displayed by exploiting a regulatory change which prohibited the display of past returns for any period shorter than twelve months. In this setting, the information displayed was altered but the information...
