The thesis of this symposium, organized by James Bicksler, was that wh
ile finance theory will surely inform practitioners, it seems appropri
ate to pay some attention to the opposite flow: practitioners can info
rm theory. Contributors include a distinguished group of practitioners
with extensive backgrounds in economics, and economists with extensiv
e public policy experience: Martin Feldstein, Robert Glauber, David Mu
llins, and Steven Wallman. Their topics range from privatizing social
security, to managing market crashes, to the regulatory agency cost pr
oblem, to regulatory constraints in a technologically advanced world.
