Belated congratulations to our former labmate Miruna Cotet
for her Paper of the Year Award from the Society for Neuroeconomics. The award celebrates her work on the cognitive dynamics of bargaining, using eBay data, published in PNAS. pnas.org/doi/abs/10.1... #SNE2025

We also find that people look less at the Buy option when there are explicit outside options. Overall, we identify two different attentional mechanisms by which the framing of opportunity costs (i.e., the outside options) impacts people's willingness to make purchases. 3/n

Across surpluses, people consistently purchase less with explicit outside options. Using a variant of the attentional DDM, we estimated separate attention discounts on the Buy and Don't Buy options. We find more discounting of the Buy option with explicit vs implicit costs. 2/n

What was really striking was the similarity of the temporal weighting function between the perceptual and economic tasks, both in the aggregate and across subjects. We estimated these weighting functions by having subjects report averages in real time using a joystick in the MRI.
