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...

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...

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....

Existing evidence suggests that the Sarbanes-Oxley Act (SOX) may be beneficial to U.S. investors, but that foreign firms are perhaps less likely to list in the U.S. after SOX. This raises the question of whether foreign firms avoid listing in the U.S. after SOX because the Act imposes...

We propose a new, valuation-based measure of world equity market segmentation. While we observe decreased levels of segmentation in many countries, the level of segmentation remains significant in emerging markets. We characterize the factors that account for variation in market segmentation...

We propose an exogenous measure of a country's growth opportunities by interacting the country's local industry mix with global price to earnings (PE) ratios. We find that these exogenous growth opportunities predict future changes in real GDP and investment in a large panel of countries. This...
