Uncertainty of supply chains: Risk and ambiguity

Kancs, D'Artis - 2024

robustness under risk aversion and ambiguity aversion. We aim to understand the potential consequences of deeply uncertain … chain-level preparedness to aggregate shocks. Augmenting a parsimonious supply chain model with uncertainty, we analyse the … relationship between the upstream sourcing decisions and the supply chain survival probability. Both risk-averse and ambiguity …

Minimizing sensitivity to model misspecification

Bonhomme, Stéphane; Weidner, Martin - In: Quantitative Economics 13 (2022) 3, pp. 907-954

We propose a framework for estimation and inference when the model may be misspecified. We rely on a local asymptotic approach where the degree of misspecification is indexed by the sample size. We construct estimators whose mean squared error is minimax in a neighborhood of the reference model,...

Minimizing sensitivity to model misspecification

Bonhomme, Stéphane; Weidner, Martin - 2018

We propose a framework for estimation and inference about the parameters of an economic model and predictions based on it, when the model may be misspecified. We rely on a local asymptotic approach where the degree of misspecification is indexed by the sample size. We derive formulas to...

Posterior average effects

Bonhomme, Stéphane; Weidner, Martin - 2021

Economists are often interested in estimating averages with respect to distributions of unobservables, such as moments of individual fixed-effects, or average partial effects in discrete choice models. For such quantities, we propose and study posterior average effects (PAE), where the average...

Investigation of Scheduling Techniques for Uncertain Conditions

Zahid, Taiba; Kühn, Mathias; Völker, Michael; … - 2015

The traditional methods and techniques employed in operational management seem unable to provide solutions that can be actually practiced. This insufficiency is caused by the uncertainties and delays which are faced in practice. The potential causes of these uncertainties are usually internal...
