On the Possibility of Credit Rationing in the Stiglitz-Weiss Model

Abstract

Contrary to what is consistently assumed in the literature, the return function cannot be hump-shaped in the Stiglitz-Weiss (1981) model. This has important consequences for the possible occurrence of credit rationing and redlining. With a single class of borrowers, banks offer credit in two stages. Demand possibly exceeds supply in stage one, but not in stage two. With several observationally distinguishable borrower classes, the firms in a borrower class are redlined only under circumstances which imply that they would not get credit in a perfect capital market either. Die Rendite-Funktion kann im Stiglitz-Weiss- (1981) Modell nicht - so wie das in der Literatur durchgängig angenommen wird - hügelförmig sein. Das hat wichtige Implikationen für die Möglichkeit von Kreditrationierung einerseits und für die Möglichkeit des Ausschlusses ganzer Kreditnehmergruppen vom Kapitalmarkt andererseits. Mit nur einer Klasse von Kreditnehmern erfolgt die Kreditvergabe in zwei Stufen. Während auf der ersten Stufe eine Übernachfrage vorliegen kann, herrscht auf der zweiten Stufe Markträumung. Bei mehreren unterscheidbaren Kreditnehmerklassen wird eine Klasse nur unter den Bedingungen vom Kreditmarkt ausgeschlossen, bei deren Vorliegen sie auch in einem vollkommenen Kreditmarkt keinen Kredit erhalten würde.
