AB  - Many previous experiments have found that, consistent with myopic loss aversion, subjects invest more in risky assets if they are given less frequent feedback about their returns, are shown their aggregated portfolio-level (rather than separate asset-by-asset) returns, or are shown long-horizon (rather than one-year) historical asset class return distributions. We study the implications of these results for the effect of financial institutions’ returns disclosure policy on risk-taking. We find that aggregated returns disclosure treatments do not increase portfolio allocations to equity in an experiment where—in contrast to previous experiments—subjects invest in real mutual funds over the course of one year.
