	abstract={This paper presents an experimentally validated survey module to measure six key economic preferences – risk aversion, discounting, trust, altruism, positive and negative reciprocity – in a reliable, parsimonious and cost-effective way. The survey instruments included in the module were the best predictors of preferences revealed in incentivized choice experiments. We also offer a streamlined version of the module that has been optimized and piloted for applications where time efficiency and simplicity are paramount, such as international telephone surveys.},
