Summary: | The global financial crisis brought
public guarantees to the forefront of the policy debate.
Based on a review of the theoretical foundations of public
guarantees, this paper concludes that the commonly used
justifications for public guarantees based solely on agency
frictions (such as adverse selection or lack of collateral)
and/or un-internalized externalities are flawed. When risk
is idiosyncratic, it is highly unlikely that a case for
guarantees can be made without risk aversion. When risk
aversion is explicitly added to the picture, public
guarantees may be justified by the state's natural
advantage in dealing with collective action failures
(providing public goods). The state can spread risk more
finely across space and time because it can coordinate and
pool atomistic agents that would otherwise not organize
themselves to solve monitoring or commitment problems.
Public guarantees may be transitory, until financial systems
mature, or permanent, when risk is fat-tailed. In the case
of aggregate (non-diversifiable) risk, permanent public
guarantees may also be justified, but in this case the state
adds value not by spreading risk but by coordinating agents.
In addition to greater transparency in justifying public
guarantees, the analysis calls for exploiting the natural
complementarities between the state and the markets in
bearing risk. |
