Standard portfolio construction models are based on the implicit assumption that all information relevant to making investment choices is probabilizable. However, both empirical behaviors of market participants and the increased success of approaches like risk parity underly an implicit...

This paper proposes a new method to introduce coherent risk measures for risks with infinite expectation, such as those characterized by some Pareto distributions. Extensions of the conditional value at risk, the weighted conditional value at risk and other examples are given. Actuarial...

This paper deals with the optimal reinsurance problem and involves the goals of both insurer and reinsurer. An important novelty may be the incorporation of the background risk that the reinsurer uses in order to diversify (or hedge) the risk ceded by the insurer. Accordingly, general methods to...

Robustness of risk measures to changes in underlying loss distributions (distributional uncertainty) is of crucial importance when making well-informed risk management decisions. In this paper, we quantify for any given distortion risk measure its robustness to distributional uncertainty by...

This paper analyzes sectoral transition risk in the US using a general equilibrium production network that captures the full supply chain. Unlike prior approaches, this model contains sufficient granularity to separate out key green and fossil-fuel sectors through its calibration on...

For years, research has been conducted to correctly model and predict the risk and return structures of Private Equity (PE) funds. Although past research has revealed valuable insight into the features of those funds, most risk and return model struggle with the dispersion of PE funds' returns,...

This paper examines to what extent information opacity exacerbates climate risks in supply chains. Understanding the information frictions in supply chain settings is important because disruptions originating from an opaque supplier can impose greater risk to the supply chain as a whole than...

Supply chain disturbances can lead to substantial increases in production costs. To mitigate these risks, firms may take steps to reduce their reliance on volatile suppliers. We construct a model of endogenous network formation to investigate how these decisions affect the structure of the...

With the Paris Agreement of 2016, 189 nations signed a legally binding document to keep global warming below 2 C, and to pursue efforts to limit the temperature increase to 1.5 C. It was recognized that this would reduce climate change impacts substantially. All signatories submitted "Intended...

This work provides an extensive overview of the input-output (IO) literature, both theoretical and empirical, dealing with the inherent IO data uncertainty issues. The survey is carried out on the basis of a specific uncertainty technique used, rather than taking a chronological overview...
