Fishing for Fools
How big is the e¤ect of a few fools on market outcomes? We argue that in auctions, even a small share of overbidding behavioral agents have a large e¤ect, because the auction format shesfor the highest-bidding behavioral buyers. Through this shing mechanism, behavioral agents disproportionately increase auction pro ts. They also generate a large welfare loss by crowding out the demand of ra...
متن کاملPoly-logarithmic independence fools AC circuits
We prove that poly-sized AC0 circuits cannot distinguish a poly-logarithmically independent distribution from the uniform one. This settles the 1990 conjecture by Linial and Nisan [LN90]. The only prior progress on the problem was by Bazzi [Baz07, Baz09], who showed that O(logn)-independent distributions fool poly-size DNF formulas. Razborov [Raz08] has later given a much simpler proof for Bazz...
متن کاملCompetent jerks, lovable fools, and the formation of social networks.
When looking for help with a task at work, people turn to those best able to do the job. Right? Wrong. New research shows that work partners tend to be chosen not for ability but for likability. Drawing from their study encompassing 10,000 work relationships in five organizations, the authors have classified work partners into four archetypes: the competent jerk, who knows a lot but is unpleasa...
متن کاملLo, what fools these mortals be.
About a tenth of Americans claim to have observed a UFO or been witness to some event that they attribute to the activity of extra-terrestrials. The number claiming actually to have met or been physically abducted by aliens from outer space is happily much lower, but the belief that this experience is real is astonishingly widespread. For not a shred of credible evidence exists to support such ...
متن کاملBounded Independence Plus Noise Fools Products
Let D be a b-wise independent distribution over {0, 1}m. Let E be the “noise” distribution over {0, 1}m where the bits are independent and each bit is 1 with probability η/2. We study which tests f : {0, 1}m → [−1, 1] are ε-fooled by D + E, i.e., |E[f(D+E)]−E[f(U)]| ≤ ε where U is the uniform distribution. We show that D+E ε-fools product tests f : ({0, 1}n)k → [−1, 1] given by the product of k...
