The Genetics of Economic Risk Preferences
Michael J Zyphur et al.; 2009
Abstract
We examine the influence of genetics on economic risk preferences by administering a measure of these preferences to monozygotic (MZ) (i.e., identical) and dizygotic (DZ) (i.e., non-identical) twin pairs. Our analysis supports a dominant genetic effect and virtually no additive genetic effect on economic risk preferences, with the heritability of preferences estimated at 0.63. These findings suggest that over half of the variation in such preferences can be explained by genetic factors, with the remainder of the variance explained by environmental influences not shared among sibling twins. We discuss the implications of our findings for the study of individual differences in economic risk preferences.
Hopefully some interesting bits of information extracted from science and non-fiction literature. (For historical reasons there are some poems scattered throughout this blog.) Sachthemen und Sachtexte. (Historisch finden sich auf diesem Blog auch einige Gedichte und Aphorismen.) [Just collecting some exciting bits of information here.] [Eine Sammlung von interessanten Texten, Fragen und Antworten will das hier sein. Nicht mehr, aber auch nicht weniger.]
