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 - 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...

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,...

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...

Strategy techniques for the times of high uncertainty
Gurkov, Igor - In: Journal for East European Management Studies 15 (2010) 2, pp. 177-186
under conditions of severe uncertainty. Through the correction of the traditional definition of stakeholders I found the … general algorithm for achieving robustness in corporate strategies. This algorithm includes: (1) the clear definition of a …

Solving the robust shortest path problem with interval data using a probabilistic metaheuristic approach
Nikulin, Yury - 2005
This paper addresses the robust shortest path problem with interval data, i.e. the case of classical shortest path problem with given source and sink when arc weights are not fixed but take their values from some intervals associated with arcs. The problem consists in finding a shortest path...

Robust Contract Conditions Under the Newly Introduced BTO-rs Scheme: Application to an Urban Railway Project
Kim, Kangsoo - In: KDI Journal of Economic Policy 42 (2020) 4, pp. 117-138
Few studies have specifically focused on the uncertainty of demand forecasting despite the fact that uncertainty is the … robust contract conditions considering uncertainty in travel demand forecasting in a PPP project. Through a case study of an … urban railway PPP project in Korea, this study uncovered the risk of excessive government payments to private partners due …
