dc.description.abstract
Since the 1980s, the microfinance sector in many countries evolved into an
economically sustainable industry and integral part of the financial system.
In order to secure the increasing refinancing needs, an increasing number of
economically successful microfinance institutions began to approach
international and also commercial investors. Actors of international
cooperation supported this process by creating or boosting the necessary
infrastructure at the meso level. This includes initiatives to establish an
adequate regulatory regime at the national level or the fostering of
information services to increase the international visibility and
transparency. The financial and political support of specialized microfinance
rating agencies is just another example. This dissertation studies the
possible contribution of rating agencies to the sustainable development of
microfinance institutions. At the same time, it provides answers to the
question which particular role specialized microfinance rating agencies play
and what this could mean for the future development of the microfinance rating
industry. The analysis and carving out of the functions of the “big three”
internationally recognized U.S. rating agencies - Moody’s, Standard & Poor‘s
and Fitch – build the theoretical conceptional framework for the study. Apart
from (micro-)economic theories the study also builds on insights from
psychology and (economic) sociology. A central element is the discussion of
the meaning of risk. Linked to this discussion the possible reliability of
rating agencies to assess future defaults is analyzed. The debate of often
criticized aspects of the activities and behavior of rating agencies is
presented. The analysis of these aspects provides further important insights
into the functionalities of rating agencies in international capital markets.
The developed analytical framework is then applied to the case of
microfinance. Using a comparative approach the study gives answers to the
question which functions of rating agencies are relevant within the
microfinance industry at the present moment. Besides, it is analyzed in how
far specialized microfinance raters distinguish themselves from conventional
rating agencies. These differences again provide insights into the context-
specific relevance of the different functions as well as the functionality of
different rating methods and products. The study shows that in the case of
Peru with its highly developed microfinance sector and partly also beyond this
specific case, ratings have a relatively important information function which
can improve the refinancing conditions of microfinance institutions. Yet,
because of the restricted functionality with regard to their certification
function they cannot be considered as critical for the access to funds. The
control function, where ratings serve as a disciplining instrument, is at the
present moment of little relevance. Still ratings have a consulting function
for less developed small microfinance institutions. The coordination function
which might foster the stability of (micro-) financial systems does not play a
role yet.

dc.description.abstract
Seit den 1980er Jahren hat sich der Mikrofinanzsektor in vielen Ländern zu
einer wirtschaftlich nachhaltigen Industrie und integralem Bestandteil des
Finanzsystems entwickelt. Um ihren hohen Refinanzierungsbedarf zu decken,
begannen eine zunehmende Anzahl von wirtschaftliche erfolgreichen
Mikrofinanzinstitutionen damit, sich internationalen, auch kommerziellen
Investoren zuzuwenden. Akteuren der internationalen Entwicklungszusammenarbeit
begleiteten diesen Prozess auch dadurch, die nötige Infrastruktur auf der
Meso-Ebene zu schaffen oder zu stärken. Die Maßnahmen reichen von der Beratung
zur Etablierung eines geeigneten, regulativen Rahmens auf nationaler Ebene bis
hin zur Schaffung von auf internationale Visibilität und Transparenz
abzielende Informationsdienste. Die politische und finanzielle Unterstützung
von auf Mikrofinanzinstitutionen spezialisierte Ratingagenturen ist hier ein
weiteres Beispiel. Diese Dissertation zielt darauf ab, den möglichen Beitrag
von Ratingagenturen für die nachhaltige Entwicklung von
Mikrofinanzinstitutionen zu ergründen. Gleichzeitig werden Antworten zu der
Frage geliefert, welche besondere Rolle den spezialisierten Ratingagenturen
dabei zukommt und was dies für mögliche Entwicklung der Mikrofinanz-Rating-
Industrie bedeuten könnte. Den theoretisch konzeptionellen Rahmen für die
Analyse bildet die Herausarbeitung der Funktionen von den drei großen,
international anerkannten U.S. Rating Agenturen: Moody’s, Standard & Poor‘s
und Fitch. Neben den (mikro-)ökonomischen Theorien basiert diese Arbeit auf
Ansätzen aus der Psychologie und (Wirtschafts-) Soziologie. Ein zentrales
Element ist dabei die Auseinandersetzung mit dem Risikobegriff und der damit
einhergehenden, möglichen Verlässlichkeit von Ratingagenturen hinsichtlich
ihrer Einschätzung von zukünftigen Zahlungsausfällen. Die Debatte hinsichtlich
oftmals kritisierter Aspekte in Bezug auf die Aktivitäten und das Verhalten
der drei großen Ratingagenturen wird dargestellt. Diese Analyse liefert
weitere, wichtige Anhaltspunkte in Bezug auf die Funktionalität von
Ratingagenturen in internationalen Kapitalmärkten. Das so erarbeitete
Analyseraster wir dann auf den Fall der Mikrofinanzindustrie angewendet. Mit
einem vergleichenden Ansatz wird zum einen der Frage nachgegangen, welche
Funktionen von Ratingagenturen zum gegenwärtigen Zeitpunkt innherhalb der
Mirkofinanzindustrie relevant sind. Zum anderen wird analysiert, inwiefern
sich die auf Mikrofinanzen spezialisierten Ratingagenturen von konventionellen
lokalen und internationalen Ratingagenturen unterscheiden. Diese Unterschiede
lassen wiederum Rückschlüsse auf die Kontext-spezifische Relevanz der
verschiedenen Funktionen sowie die Funktionalität unterschiedlicher
Ratingmethoden und –produkte zu. Die Studie zeigt, dass, für den Fall von Peru
mit seinem weit entwickelten Mikrofinanzsektor, aber zum Teil auch darüber
hinaus Ratings eine relativ wichtige Informationsfunktion haben und damit die
Konditionen der Refinanzierung von Mikrofinanzinstitutionen verbessern können.
Die eingeschränkte Funktionalität von Ratings in Bezug auf die
Zertifizierungsfunktion lassen sie jedoch nicht als kritisch für den Zugang zu
Refinanzierungsquellen erscheinen. Die Kontrollfunktion, bei der Ratings ein
Disziplinierungsinstrument darstellen, ist bis dato wenig ausgeprägt. Ratings
haben jedoch vor allem für weniger weit entwickelte, kleine
Mikrofinanzinstitutionen eine Beratungsfunktion. Die Koordinationsfunktion als
Garant für die Stabilität des (Mikro-) Finanzsystems spielt im
Mikrofinanzsektor noch keine Rolle.
