In this paper, an algorithm for the fast computation of network reliability bounds is proposed. The evaluation of the network reliability is an intractable problem for very large networks, and hence approximate solutions based on reliability bounds have assumed importance. The proposed bounds...

Probabilistic Risk Assessment is being increasingly used in a number of industries such as nuclear, aerospace, chemical process, to name a few. Probabilistic Risk Assessment (PRA) characterizes risk in terms of three questions: (1) What can go wrong? (2) How likely is it? (3) What are the...

This paper develops a simple model of international lending, and calibrates it to assess quantitatively the effects of contingent IMF financial support on the risk premiums and the crisis probability. In the model, the country borrows in both short and long term; market (coordination) failure...
