We compare the standard one-bid first price auction to a corresponding two-bid first price auction where each buyer may place two bids: a high bid and a low one and the winner pays his low bid if this was higher than all other bids. We characterize the equilibria of the two mechanisms and prove...

Experimental studies of risk and time-preference typically focus on one of the two phenomena. The goal of this paper is to investigate the (possible) correlation between subjects' attitude to risk and their time-preference. For this sake we ask 61 subjects to price a simple lottery in 3...

Previous research suggests that human reaction to risky opportunities reflects two contradicting biases: "loss aversion", and "limited level of reasoning" that leads to overconfidence. Rejection of attractive gambles is explained by loss aversion, while counterproductive risk seeking is...

The close to zero interest rates past the economic crisis open possibility to directly test for loss aversion in framed field structured investment tasks. We use a Web-survey platform to compare the willingness to invest in LOSS-GAIN deposits that pay positive return G in favorable market...

The willingness to trust human receivers is compared to the inclination to take lottery risk in six distinct scenarios, controlling the return distributions. Trust shows significantly smaller responsiveness to return expectations compared to parallel pure-risk lottery allocation, and paired...

The return on composite investment instruments takes the form of weighted-average, derived from the performance of at least two economic indicators. Three allocation experiments illustrate that prospective investors tend to valuate composites "by-tranche", consistently violating the rational...

Class and field surveys revealed that personal inclination to take structured lottery-risk significantly correlates with optimism in financial forecasting. Trait optimism reflects in return predictions for successful and problematic stocks, in likelihood assessments of specific events, and even...
