Life insurer cost of equity with asymmetric risk factors

Includes bibliographical references (pages 17-19).Published as: The Finanicial Review, vol. 50, no. 3, July 2015, pp. 435-457, https://doi.org/10.1111/fire.12073.This study presents an improved model for estimating life insurer cost of capital with the inclusion of upside and downside risk factors and controlling for life insurer characteristics. Although various asymmetric measures of market risk have been shown to be priced factors for the broader equity market, life insurer realized equity returns include a much larger premium for bearing downside risk, even after controlling for firm characteristics and other measures of risk. Cross‐sectional regression analysis finds a positive (negative) premium for downside (upside) betas, conditional on down and up markets, respectively. Coskewness and cokurtosis are also priced factors

A Combination of Dopamine Genes Predicts Success by Professional Wall Street Traders

What determines success on Wall Street? This study examined if genes affecting dopamine levels of professional traders were associated with their career tenure. Sixty professional Wall Street traders were genotyped and compared to a control group who did not trade stocks. We found that distinct alleles of the dopamine receptor 4 promoter (DRD4P) and catecholamine-O-methyltransferase (COMT) that affect synaptic dopamine were predominant in traders. These alleles are associated with moderate, rather than very high or very low, levels of synaptic dopamine. The activity of these alleles correlated positively with years spent trading stocks on Wall Street. Differences in personality and trading behavior were also correlated with allelic variants. This evidence suggests there may be a genetic basis for the traits that make one a successful trader

ON THE LINKAGE BETWEEN FINANCIAL RISK TOLERANCE AND RISK AVERSION

We explore the linkage between financial risk tolerance (FRT) and risk aversion. To do this, we obtain FRT scores from a psychometrically validated survey and conduct a battery of online lottery choice experiments involving the same nonstudent participants. We contrast: real and hypothetical payoffs, low and high stakes, decisions involving gains and losses, and order effects. Our key finding is that the two approaches to analyzing decision making under uncertainty are strongly aligned. We present evidence that this is particularly the case for the female participants in our sample and when high-stake gambles are employed. 2008 The Southern Finance Association and the Southwestern Finance Association.

Yours, Mine, or Ours: Tax-Related Decision Responsibility of Married Couples

Purpose: Examine tax-related decisions of married couples to determine whether decisions are made jointly or if one spouse dominates the decision. We also examine characteristics related to decision styles. Methodology/approach: Questionnaires completed independently by both the husband and wife. Findings: Nearly 40 percent of the couples make tax decisions jointly, while the remaining couples allow one spouse to dominate tax-related decisions. The results indicate that when one spouse dominates the decisions, it is most often the wife. We also find that couples are more likely to share tax-related decision responsibility jointly when the husband earns significantly more than the wife, when the couple has greater income as a family, and when they are a new couple. Research limitations/implications: Prior research has generally not recognized tax decisions by married couples as a joint decision or attempted to determine whether tax decisions are dominated by the husband or wife. This issue has implications for interpreting research results in light of prior research that has found that tax-related decisions vary significantly by gender. The finding that many couples make joint decisions suggests that an interesting avenue for future research would be to determine the nature of that joint decision making and whether it is collaborative, bargaining, or something else. Originality/value: Prior research on tax-related decisions has not recognized that for approximately 40 percent of tax returns filed, the unit of study is not a single individual but a married couple
