Big Decisions: Opting, Converting, Drifting

Failure to Launch: From Big Data to Big Decisions

Why velocity, variety and volume is not improving decision making and how to fix it

Two methods of obtaining parental consent for this process were tested. High recruitment rates were achieved using an 'opting out' approach.

Defaults, Framing and Privacy: Why Opting In Opting Out

Opting Into Optimal Matchings

We revisit the problem of designing optimal, individually rational matching mechanisms (in a general sense, allowing for cycles in directed graphs), where each player — who is associated with a subset of vertices — matches as many of his own vertices when he opts into the matching mechanism as when he opts out. We offer a new perspective on this problem by considering an arbitrary graph, but as...

Symposium Issue† Privacy in the Age of Big Data: a Time for Big Decisions

We live in an age of “big data.” Data has become the raw material of production, a new source of immense economic and social value. Advances in data mining and analytics and the massive increase in computing power and data storage capacity have expanded, by orders of magnitude, the scope of information available to businesses, government, and individuals.1 In addition, the increasing number of ...
