An important assumption underlying the designation of some insurers as systemically important is that their overlapping portfolio holdings can result in common selling. We measure the overlap in holdings using cosine similarity, and show that insurers with more similar portfolios have larger...

We examine whether the concern of academics and regulators about the potential for insurers tosell similar assets due to the overlap in their holdings is justified. We measure this overlap usingcosine similarity and find that insurers with more similar portfolios have larger subsequent...

This paper extends the classic factor-based asset pricing model by including network linkages in linear factor models. We assume that the network linkages are exogenously provided. This extension of the model allows a better understanding of the causes of systematic risk and shows that (i)...
