Sources of information and portfolio allocation

This research investigates the relationship between how a household receives financial information and the degree to which investment portfolios are diversified. Diversification is measured as allocation across asset classes and share of assets held in each asset class. Propensity score-based techniques incorporating stratification and weighting are employed to better isolate causal links, while also controlling for objective and subjective financial literacy and overconfidence. Results indicate that the use of financial planners and brokers is associated with an increase in asset class diversification. Households that consult with financial planners and bankers allocate their wealth systematically different from those who do not. These results highlight the role that financial professionals play in helping households make investment decisions.
