A Robust Approach to Optimal Portfolio Choice with Parameter Uncertainty
Lassance, Nathan; Martin-Utrera, Alberto; Simaan, Majeed - 2021
It is well known that estimated mean-variance portfolios deliver, on average, poor out-of-sample performance. A lesser-known fact that we characterize in this paper is that their out-of-sample performance is also very volatile. Using our analytical characterization of out-of-sample performance...

Uncertain identification
Giacomini, Raffaella; Kitagawa, Toru; Volpicella, Alessio - In: Quantitative economics : QE ; journal of the … 13 (2022) 1, pp. 95-123
Uncertainty about the choice of identifying assumptions is common in causal studies, but is often ignored in empirical practice. This paper considers uncertainty over models that impose different identifying assumptions, which can lead to a mix of point‐ and set‐identified models. We propose...

Robustness
Hansen, Lars Peter; Sargent, Thomas J. - 2008
The authors adapt modern control theoretic techniques based on robust control theory to economic modelling and decision … entropy and in this sense the robust control theory is not only adapted but also extended in the book. The main issues … noncooperative game theory to solve the formulated decision making problems. The book is self-contained and rigorous and may be …

Structural models for policy-making: coping with parametric uncertainty
Eisenhauer, Philipp; Gabler, Janos; Janys, Lena - 2021
The ex-ante evaluation of policies using structural econometric models is based on estimated parameters as a stand-in for the truth. This practice ignores uncertainty in the counterfactual policy predictions of the model. We develop a generic approach that deals with parametric uncertainty using...

Plausible prior estimation
Mangold, Benedikt - 2014
The problem of selecting a prior distribution when it comes to Bayes estimation often constitutes a choice between conjugate or noninformative priors, since in both cases the resulting posterior Bayes estimator (PBE) can be solved analytically and is therefore easy to calculate. Nevertheless,...
