Incentive Audits: A New Approach to Financial Regulation. By Martin Cihak

Economists often disagree on policy advice. If
you ask 10 of them, you may get 10 different answers, or more. But from
time to time, economists actually do agree. One such area of agreement
relates to the role of incentives in the financial sector. A large and
growing literature points to misaligned incentives playing a key role in
the run-up to the global financial crisis. In a
recent paper, co-authored with Barry Johnston, we propose to address the incentive breakdowns head-on by performing “incentive audits”.
The global financial crisis has highlighted the destructive impact of
misaligned incentives in the financial sector. This includes bank
managers’ incentives to boost short-term profits and create banks that
are “too big to fail”, regulators’ incentives to forebear and withhold
information from other regulators in stressful times, credit rating
agencies’ incentives to keep issuing high ratings for subprime assets,
and so on. Of course, incentives play an important role in many economic
activities, not just the financial ones. But nowhere are they as
prominent, and nowhere can their impact get as damaging as in the
financial sector, due to its leverage, interconnectedness, and systemic
importance. A large body of recent literature examines these issues in
depth. For example, Caprio, Demirgüç-Kunt and Kane (2008) show that
incentive conflicts explain how securitization went wrong and why credit
ratings proved so inaccurate; Barth, Caprio and Levine (2012) highlight
incentive failures in regulatory authorities. Incentives were not the
only factor – they were accentuated by problems of insufficient
information, herd behavior, and so on – but breakdowns in incentives had
clearly a central role in the run-up to the crisis.
Despite the broad agreement among economists, the focus of financial
sector regulation and supervision has often been on other things,
leaving incentives to be addressed indirectly at best. At the global
level, substantial efforts have been devoted to issues such as
calibrating risk weights to calculate banks’ minimum capital
requirements. Numerous outside observers have called for more concerted
efforts to address the incentive breakdowns that led to the crisis
(e.g., LSE 2010; Squam Lake Working Group 2010; and Beck 2010). At the
individual country level, regulatory changes have taken place in recent
years, but in-depth analyses show a major scope to better address
incentive problems (see
Čihák, Demirgüç-Kunt, Martínez Pería, and Mohseni 2012, based on data from the World Bank’s
2011–12 Bank Regulation and Supervision Survey). The World Bank’s
2013 Global Financial Development Report also called for more vigorous steps to address incentive issues, rather than leaving them as an afterthought.
In a
recent paper,
joint with Barry Johnston, we propose a pragmatic approach to
re-orienting financial regulation to have at its core addressing
incentives on an ongoing basis. The paper, which of course represents
our views and not necessarily those of the World Bank, proposes
“incentive audits” as a tool to help in identifying incentive
misalignments in the financial sector. The paper is an extended version
of an earlier piece recognized by the International Centre for Financial
Regulation and the Financial Times among
top essays on “what good regulation should look like“.
The incentive audit approach aims to address systemic risk buildup
directly at its source. While traditional, regulation-based approaches
focus on building up capital and liquidity buffers in financial
institutions, the incentive-based approach seeks to identify and correct
distortions and frictions that contribute to the buildup of excessive
risk. It goes beyond the symptoms to their source. For example, the
buildup of massive risk concentrations before the crisis could be
attributed to information gaps that prevented the assessment of
exposures and network risks, to incentive failures in the monitoring of
the risks due to conflicts of interest and moral hazard, and to
regulatory incentives that encouraged risk transfers. Building up
buffers can help, but to address systemic risk effectively, it is
crucial to tackle the underlying incentives that give rise to it.
Focusing on increasingly complex capital and liquidity charges has the
danger of creating incentives for circumvention, and can run into
limited capacity for implementation and enforcement. In the
incentive-based approach, more emphasis is given on methods for
identifying incentive failures resulting in systemic risk. The remedies
go beyond narrowly defined prudential tools and include also other
measures, such as elimination of tax incentives that encourage excessive
borrowing.
What would an incentive audit involve? It would entail an analysis of
structural and organizational features that affect incentives to
conduct and monitor financial transactions. It would comprise a
sequenced set of analyses proceeding from higher level questions on
market structure, government safety nets and legal and regulatory
framework, to progressively more detailed questions aimed at identifying
the incentives that motivate and guide financial decisions (Figure 1).
This sequenced approach enables drilling down and identifying factors
leading to market failures and excessive risk taking.

The incentive audit is a novel concept,
but analysis of incentives has been done. One example is the report of a
parliamentary commission examining the roots of the Icelandic financial
crisis. The report (
Special Investigation Commission 2010)
notes the rapid growth of Icelandic banks as a major contributor of the
crisis. It documents the underlying “strong incentives for growth”,
which included the banks’ incentive schemes and the high leverage of
their owners. It maps out the network of conflicting interests of the
key owners, who were also the largest debtors of these banks. Another
example of work that is close to an incentive audit is the analysis by
Calomiris (2011). He examines incentive failures in the U.S. financial
market, and identifies a subset of reforms that are “incentive-robust,”
that is, they improve market incentives, market discipline, and
incentives of regulators and supervisors by making rules and their
enforcement more transparent, increasing credibility and accountability.
These examples illustrate that an incentive audit is doable and useful.
Who would perform incentive audits? Our paper
offers some suggestions.
The governance of the institution performing the audits is
important--its own incentives to act need to be appropriately aligned.
Also, to be effective, incentive audits would have to be performed
regularly, and their outcomes would have to be used to address incentive
issues by adapting regulation, supervision, and other measures. In
Iceland, the analysis of incentives was a part of a “post mortem” on the
crisis, but it is feasible to do such analysis ex-ante. Indeed, much of
the information used in the above mentioned report was available even
before the crisis. The Commission had modest resources, illustrating
that incentive audits need not be very costly or overly complicated to
perform. As the Commission’s report points out, “it should have been
clear to the supervisory authorities that such incentives existed and
that there was reason for concern,” but supervisors “did not keep up
with the rapid changes in the banks’ practices”. Instead of examining
the reasons for the changes, the supervisors took comfort in banks’
capital ratios exceeding a statutory minimum and appearing robust in
narrowly-defined stress tests (
Čihák and Ong 2010).
An incentive audit needs to be complemented by other tools. It needs
to be combined with quantitative risk assessment and with assessments of
the regulatory, supervisory, and crisis preparedness frameworks. The
audit provides an organizing framework, putting the identification and
correction of incentive misalignments front and center.
Incentive audits are not a panacea, of course. Financial markets
suffer from issues that go beyond misaligned incentives, such as limited
rationality, herd behavior and so on. But better identifying and
addressing incentive misalignments is a key practical step, and the
incentive audits can help.
