On Three-Layer Data Markets
We study a three-layer data market comprising users (data owners), platforms, and a data buyer.
The Limits of Price Discrimination Under Privacy Constraints
We consider a privacy mechanism that provides a degree of protection by probabilistically masking each market segment, and we establish that the resultant set of all consumer-producer utilities forms a convex polygon, characterized explicitly as a linear mapping of a certain high-dimensional convex polytope into $\mathbb{R}^2$.
Optimal and Differentially Private Data Acquisition: Central and Local Mechanisms
We consider a platform's problem of collecting data from privacy sensitive users to estimate an underlying parameter of interest.
Network Maximal Correlation
For jointly Gaussian variables, we show that under some conditions the NMC optimization is an instance of the Max-Cut problem.
