Optimal
Certification Design (Job Market Paper), November 2010
|
Abstract
This
paper analyzes the rating of a product of
unknown quality by a certifier who internalizes the buyers' surplus
and receives payments from a seller. It shows that contrary to
conventional wisdom, a regulation that prohibits contingent payments
hinders information revelation and harms social welfare when the
contract between seller and certifier is public. If the contract is
private (buyers do not observe the payments), contingent payments
lead to “rating inflation”: high ratings are issued for a wide
range of qualities and ratings have limited information value.
Mandating flat fees then prevents rating inflation and can increase
welfare.

Scarce
Monitoring Capital, Underpricing of IPOs and Discrimination Between
Investors, November 2009
|
Abstract
When
issuers use uniform fixed price offerings and compete for monitoring
capital, monitors, being scarce, capture some rent during the IPO and
reduce the attractiveness of shares for retail investors. In order to
attract retail investors the issuer has to underprice its shares.
Bookbuilding allows issuers to discriminate among investors. If
issuers use bookbuilding they are worse off compared to the
situation where they stick to a fixed price offering,
because discrimination triggers Bertrand competition for scarce
monitors and forces issuers to give them all the rent. In contrast,
in a uniform fixed price offering the competition for monitors is less severe since the effective price charged for monitors is the same
as the fair price for retail investors and it is never profitable for
the issuer to attract a monitor by charging a lower price.

Wisdom of The Crowd, March 2010
|
Abstract
In
environments where proceeds of new ventures are difficult to assess
for outsiders projects are often started by experts. However,
eventually the ventures must be "sold" to outsiders for
experts to cash in. The following question arises why uninformed outsiders
would be willing to buy ventures from informed experts? We show that
if a family of similar projects can be started by numerous experts,
some information about the prospects of projects is revealed to outsiders
when the experts bring projects to the market. If many experts are
selling projects it must be the case that many of them found their
projects promising, and outsiders' valuations of these projects
increase. Thus the information of individual experts gets aggregated and
revealed to outsiders through the experts' actions (wisdom of the
crowd). This mechanism exhibits strategic complementarity among
experts' decisions to investigate projects. If many experts
investigate and start projects then the market price reveals a
project's prospects and this in turn creates incentives for an expert
to investigate and start a project in the case of a good signal. If,
on the other hand, no expert investigates, the market price is not
revealing and an expert has no incentives to investigate. Given that
a venture started at random without an investigation has a negative
expected value, the market for new ventures ceases.
