Laissez-Faire Capitalism Has Failed

It is now clear that this is the worst financial crisis since the
Great Depression and the worst economic crisis in the last 60 years.
While we are already in a severe and protracted U-shaped recession
(the deluded hope of a short and shallow V-shaped contraction has
evaporated), there is now a rising risk that this crisis will turn
into an uglier, multiyear, L-shaped, Japanese-style stag-deflation (a
deadly combination of stagnation, recession and deflation).

Unfortunately, the euro zone is well behind the U.S. in its policy
efforts for several reasons. The first is that the European Central
Bank is behind the curve in cutting policy rates and creating
nontraditional facilities to deal with the liquidity and credit
crunch. The second is that the fiscal stimulus is too modest, because
those who can afford it (Germany) are lukewarm about it, and those who
need it the most (Spain, Portugal, Greece, Italy) can least afford it,
as they already have large budget deficits. The last reason is that
there is a lack of cross-border burden sharing of the fiscal costs of
bailing out financial institutions.

At some point a sovereign bank may crack, in which case the ability of
governments to credibly commit to act as a backstop for the financial
system, including deposit guarantees, could come unglued.

Thus the L-shaped, near-depression scenario is still quite possible (I
assign it a 30% probability), unless appropriate and aggressive policy
action is undertaken by the U.S. and other economies.

This severe economic and financial crisis is now also leading to a
severe backlash against financial globalization, free trade and the
free-market economic model.

There is the failure of ideas--such as the "efficient market
hypothesis," which deluded its believers about the absence of market
failures such as asset bubbles; the "rational expectations" paradigm
that clashes with the insights of behavioral economics and finance;
and the "self-regulation of markets and institutions" that clashes
with the classical agency problems in corporate governance--that are
themselves exacerbated in financial companies by the greater degree of
asymmetric information.

This crisis also shows the failure of ideas such as the one that
securitization will reduce systemic risk rather than actually increase
it. That risk can be properly priced when the opacity and lack of
transparency of financial firms and new instruments leads to
unpriceable uncertainty rather than priceable risk.

But the design of the new system should be robust enough to counter
three types of problems with rules:

* A tendency toward "regulatory arbitrage" should be kept in mind, as
bankers can find creative ways to bypass rules faster than regulators
can improve them.

* Then there is "jurisdictional arbitrage," as financial activity may
move to more lax jurisdictions.

* And, finally, "regulatory capture," as regulators and supervisors
are often captured--via revolving doors and other mechanisms--by the
financial industry.

So the new rules will have to be incentive-compatible, i.e., robust
enough to overcome these regulatory failures.
