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,...

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...

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

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....

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 measure a country's growth opportunities by investigating how its industry mix is priced in global capital markets, using price earnings ratios of global industry portfolios. We derive three sets of empirical results. First, these exogenous growth opportunities strongly predict future changes...

We propose a new, valuation-based measure of world equity market segmentation. While we observe decreased levels of segmentation in many developing countries, the level of segmentation is still significant. In contrast to previous research, we characterize the factors that account for variation...

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...

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...
