Solow on Leverage
Tuesday, April 21st, 2009Robert M. Solow, the 1987 Nobel Prize winner in Economics, has written an enlightening review of a book called “How to Understand the Disaster” (i.e., the current credit crisis) in The New York Review of Books. Here are two quotes:
“[…] it is leverage that turns large banks and financial institutions into ninepins that cannot fall without knocking down others that cannot fall without knocking down still others. That seems to be the key to the potential instability of an unregulated financial system.”
and
“A modern capitalist economy with a modern financial system can probably adapt to minor shocks—positive or negative—with just a little help from monetary policy and mostly automatic fiscal stabilizers: […] But that same financial system has intrinsic characteristics that can make it self-destructively unstable when it meets a large shock. One such characteristic is asymmetric information: some market participants know things that others don’t, and can turn that knowledge into profit”,
which is somewhat related to my (danish) post from yesterday.
