Fairness and Efficiency in Multiportfolio Optimization

By: Dan A. Iancu and Nikolaos Trichakis

We deal with the problem faced by a portfolio manager in charge of multiple accounts. We argue that because of market impact costs, this setting differs in several subtle ways from the classical (single account) case, with the key distinction being that the performance... View Details

Oracle Efficient Private Non-Convex Optimization

By: Seth Neel, Aaron Leon Roth, Giuseppe Vietri and Zhiwei Steven Wu

One of the most effective algorithms for differentially private learning and optimization is objective perturbation. This technique augments a given optimization problem (e.g. deriving from an ERM problem) with a random linear term, and then exactly solves it.... View Details

Non-verifiability, Costly Renegotiation, and Efficiency

By: Jerry R. Green and J. J. Laffont

We study the implications of the non verifiability of information for the allocation of resources and the bearing of risk in a two party relationship. We consider a two step approach. In step one the two parties define a non contingent contract which will be executed... View Details

Pareto Efficiency in Robust Optimization

By: Dan Iancu and Nikolaos Trichakis

This paper formalizes and adapts the well-known concept of Pareto eﬃciency in the context of the popular robust optimization (RO) methodology for linear optimization problems. We argue that the classical RO paradigm need not produce solutions that possess the... View Details
