Economic power is a country's capacity to harm another more than itself by withdrawing from a trading relationship. This paper develops a short-run model of trade disruptions to me…
Macroeconomic Risks from Maritime Trade Disruptions
Vipin P. Veetil, Fathimath S. Vemmarath
This paper develops a model of maritime chokepoint closures in which interrupting a shipping passage produces losses that are not measured, or even bounded, by the value of the tra…
Forced condensation and anti-condensation on heavy-tailed networks
Ashwin Bhattathiripad, T. Ashwin Bhattathiripad, Vipin P. Veetil
We study a driven selection mechanism on a fixed heavy-tailed network. At each step, a power-normalization rule recomputes the direction of fresh injection from the current mass pr…

A tight alignment between the degree vector and the leading eigenvector arises naturally in networks with neutral degree mixing and the absence of local structures. Many real-world…
