We find that a significant proportion of the cross-sectional variation in the choice to own or rent is attributable to a genetic factor, while parental influence is not found to affect this choice. We also find evidence of gene-environment interactions: The environment moderates genetic effects...

For a long list of investment “biases,” including lack of diversification, excessive trading, and the disposition effect, we find that genetic differences explain up to 45% of the remaining variation across individual investors, after controlling for observable individual characteristics....

What are the origins of individual savings behavior? Using data on identical and fraternal twins matched with data on their savings behavior, we find that an individual's savings propensity is governed by both genetic predispositions, social transmission from parents to their children, and...

Using data on identical and fraternal twins' complete financial portfolios, we decompose the crosssectional variation in investor behavior. We find that a genetic factor explains about one third of the variance in stock market participation and asset allocation. Family environment has an effect...

At a time of historic challenges to the viability of the Eurozone, we assess the contribution of the EU and the Euro to equity market integration in Europe. We use a simple and essentially model free measure of bilateral market segmentation: two countries are segmented if there is a wide...

We introduce a new, market-based and forward-looking measure of political risk derived from the yield spread between a country’s US dollar debt and an equivalent US Treasury bond. We explain the variation in these sovereign spreads with four factors: global economic conditions,...
