Provisional Score Dynamics for NASA REALM RFID
Figure 1. The figure shows provisional scores (as percents of the theoretical maximum score) of each submission in a contest as a function of the time it was submitted. The larger dot sizes correspond to higher final placements of the submission authors. The submissions from the five winners of the contest are distinguished by colors. The two NASA benchmarks are shown by horizontal lines.
Learning about Bargaining from eBay’s Best Offer Platform
Abstract: The economics literature on bargaining is rich in theory and experiments and poor in empirical work, particularly from real-world bargaining. Data from online negotiations on eBay’s “Best Offer” platform offer a unique chance to remedy this. In that setting we document patterns of behavior and relate them to “rational” and “psychological” theories of bargaining and find […]
Where Do New Things Come From, and What Do We Do When We Get Them?
Abstract: What is the cognitive science of how we process the new, the unexpected, the pattern-breaking? I’ll present some reasons to think the human race is, by default, a novelty-rejection machine. And I’ll show empirical work that shows how communities, institutions, and the exceptional individual can overcome basic cognitive biases to create new science, new […]
Mobile Targeting Using Customer Trajectory Patterns
Abstract: Rapid improvements in the precision of mobile technologies now make it possible for advertisers to go beyond real-time static location and contextual information on consumers. In this paper, we propose a novel “trajectory-based” targeting strategy for mobile recommendation that leverages detailed information on consumers’ physical-movement trajectories using fine-grained behavioral information from different mobility dimensions. […]
Optimal Economic Design through Deep Learning
Abstract: Designing an auction that maximizes expected revenue is a major open problem in economics. Despite significant effort, only the single-item case is fully understood. We ask whether the tools of deep learning can be used to make progress. We show that multi-layer neural networks can learn essentially optimal auction designs for the few problems that […]
Upstream, Downstream: Diffusion and Impact of the Universal Product Code
Abstract: This paper matches archival data from the Uniform Code Council to establishments in the Longitudinal Business Database and Economic Census to study the diffusion and impacts of the Universal Product Code (UPC). We find evidence of network effects in the diffusion process. Matched-sample difference-in-difference estimates show that employment and trademark registrations increase following UPC adoption […]
