Abstract

Financial institutions form multilayer networks by engaging in contracts with each other and by holding exposures to common assets. As a result, the default probability of one institution depends on the default probability of all of the other institutions in the network. Here, we show how small errors on the knowledge of the network of contracts can lead to large errors in the probability of systemic defaults. From the point of view of financial regulators, our findings show that the complexity of financial networks may decrease the ability to mitigate systemic risk, and thus it may increase the social cost of financial crises.

Attention Score in Context

This research output has an Altmetric Attention Score of 97. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 18 September 2019.
All research outputs
#222,379
of 15,897,991 outputs
Outputs from Proceedings of the National Academy of Sciences of the United States of America
#4,758
of 86,145 outputs
Outputs of similar age
#6,783
of 267,111 outputs
Outputs of similar age from Proceedings of the National Academy of Sciences of the United States of America
#135
of 885 outputs
Altmetric has tracked 15,897,991 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 98th percentile: it's in the top 5% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 86,145 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 28.7. This one has done particularly well, scoring higher than 94% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 267,111 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 97% of its contemporaries.
We're also able to compare this research output to 885 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 84% of its contemporaries.
