Colin Camerer and Taisuke Imai will conduct a large-scale meta-analysis of both published and unpublished studies involving risk aversion and time preference in economics, psychology, and neuroscience. The meta-analysis design involves estimate weighting according to study quality, bias estimation, and the resolution of parameter variation across methods or populations. For risk aversion, the researchers will locate and meta-analyze studies estimating parameters associated with the curvature of utility and loss-aversion (i.e., the ratio between disutility of loss and utility of gain). For time preferences, they will locate and meta-analyze studies estimating parameters associated with near- and long-term discounting. Results forthcoming.
