Risk and Time Preferences: Linking Experimental and Household Survey Data from Vietnam

American Economic Review 2010 100(1), 557-571
We conducted experiments in Vietnamese villages to determine the predictors of risk and time preferences. In villages with higher mean income, people are less loss-averse and more patient. Household income is correlated with patience but not with risk. We expand measurements of risk and time preferences beyond expected utility and exponential discounting, replacing those models with prospect theory and a three-parameter hyperbolic discounting model. Comparable risk parameter estimates have been found for Chinese farmers, using our method. (C83, D12, O12, P38)

Large Foreign Ownership and Firm-Level Stock Return Volatility in Emerging Markets

Journal of Financial and Quantitative Analysis 2011 46(4), 1127-1155
This study constructs a firm-level measure of large foreign ownership (LFO) and investigates its impact on stock return volatility in 31 emerging markets. We find a negative relationship between LFO and volatility, even after controlling for potential endogeneity and the impact of major domestic shareholders. This suggests a stabilizing role of LFO in emerging markets, which is consistent with previous suggestions in the literature on the strong commitments and potential monitoring role of large foreign shareholders. Overall, our study highlights the importance of recognizing the heterogeneity among foreign investors and the benefits of large foreign shareholders to emerging stock markets.
