Kreditgenossenschaften: Marktstruktur, Wettbewerb und Verhalten. Das Beispiel Paraguay

Credit unions: market structure, competition and behavior. The example of Paraguay
Andreas Schneider

Zusammenfassung

Konzentrations- und Wettbewerbsmaße im Finanzsektor sind wichtig, um die öffentliche Politik zu orientieren. Genossenschaften, insbesondere im Kontext kleiner Entwicklungsländer, werden in der Wirtschaftsliteratur jedoch weitgehend ignoriert. Die empirische Analyse ist aufgrund der Datenverfügbarkeit deskriptiv und analysiert den Kreditmarkt großer Kreditgenossenschaften. Wir nutzen hierfür eine gepaarte Stichprobe, ausgewählt nach dem Konzentrationsprinzip, für die wir statische Konzentrationsmaße berechnen. Trotz der nicht repräsentativen Datenlage sind die Ergebnisse indikativ und bieten einen ersten Ausgangspunkt für Institutionen und Genossenschaften. Die Ergebnisse zeigen, dass die Kreditvergabe innerhalb des Genossenschaftssystems im Allgemeinen stark konzentriert ist und der Kreditmarkt praktisch in den Händen von zwei Genossenschaften liegt. Die Beteiligung kleiner Genossenschaften ist auf einen unbedeutenden Wert gesunken. Es scheint, dass die Marktkonzentration mit einer kontinuierlichen internen Migration zusammenhängt. Der Kreditmarkt großer Finanzgenossenschaften ist insgesamt nicht konzentriert, die meisten Kreditmodalitäten sind jedoch stark konzentriert, einige sind wettbewerbsfähig, andere nicht. Es gibt keine Hinweise auf einen Marktmissbrauch der drei größten Kreditgenossenschaften.

Abstract

Measures of concentration and competition in the financial sector are important to determine public policies. However, cooperatives, and in particular in the context of small developing countries are largely ignored in economic literature. The empirical analysis is descriptive due to data availability and analysis the loan market of large credit cooperatives. We use a paired sample, selected according to the concentration principle, for which we calculate static concentration measures. Despite the unrepresentative data situation, the results are indicative and offer a first starting point for institutions and cooperatives. Results show that, in general, the cooperative system is highly concentrated, and the loan market is in the hands of two cooperatives. The participation of small cooperatives has dropped to an insignificant level. It seems that market concentration is related to a continuous internal migration. The loan market of large financial cooperatives is not concentrated, however, most loan modalities are highly concentrated, some are competitive and some are not. There is no indicative evidence of market abuse of the three largest credit cooperatives.

Resumée

Les mesures de la concentration et de la concurrence dans le secteur financier sont importantes pour orienter la politique publique. Cependant, les coopératives, en particulier dans le contexte des petits pays en développement, sont largement ignorées dans la littérature économique. En raison de la disponibilité des données, l'analyse empirique est descriptive et analyse le marché du crédit des grandes coopératives de crédit. Pour cela, nous utilisons un échantillon aléatoire apparié, sélectionné selon le principe de concentration, pour lequel nous calculons des mesures de concentration statiques. Malgré la situation des données non représentatives, les résultats sont indicatifs et offrent un premier point de départ pour les institutions et les coopératives. Les résultats montrent que les prêts au sein du système coopératif sont généralement très concentrés et que le marché du crédit est effectivement entre les mains de deux coopératives. La participation des petites coopératives est tombée à un niveau insignifiant. Il semble que la concentration du marché soit liée à une migration interne continue. Le marché des prêts des grandes coopératives financières n'est généralement pas concentré, mais la plupart des modalités de prêt sont très concentrées, certaines compétitives et d'autres non. Il n'y a aucune preuve d'abus de marché par les trois plus grandes coopératives de crédit.
