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

Optimal Reserve Management and Sovereign Debt

By: Laura Alfaro and Fabio Kanczuk
Most models currently used to determine optimal foreign reserve holdings take the level of international debt as given. However, given the sovereign's willingness-to-pay incentive problems, reserve accumulation may reduce sustainable debt levels. In addition, assuming... View Details

Optimal Tilts: Combining Persistent Characteristic Portfolios

By: Malcolm Baker, Ryan Taliaferro and Terry Burnham
We examine the optimal weighting of four tilts in U.S. equity markets from 1968 through 2014. We define a “tilt” as a characteristic-based portfolio strategy that requires relatively low annual turnover. This is a continuum, with small size (a very persistent... View Details

The Optimal Stock Valuation Ratio

By: Sebastian Hillenbrand and Odhrain McCarthy
Trailing price ratios, such as the price-dividend and the price-earnings ratio, scale prices by trailing cash flow measures. They theoretically contain expected returns, yet, their performance in predicting stock market returns is poor. This is because of an omitted... View Details

On the Optimal Structure of Liability Laws

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

Reputational Contagion and Optimal Regulatory Forbearance

By: Alan Morrison and Lucy White
Existing studies suggest that systemic crises may arise because banks either hold correlated assets or are connected by interbank lending. This paper shows that common regulation is also a conduit for interbank contagion. One bank's failure may undermine confidence in... View Details
