Network analysis applications to payment and financial systems  Research in network theory has received relatively little attention in economics until the last decade. Therefore, I am delighted to see that this literature is growing and today’s workshop clearly illustrates its growing importance.
The papers from today’s program highlight how direct and indirect interlinkages and contagion dynamics among financial institutions, as well as among institutions, markets and infrastructures, can be significantly influenced by three important network characteristics: First, the degree of connectivity, second, the degree of concentration and third, the size of exposures.
