Tacit Collusion in a Segmented and Capacity Constrained Informal Rural Credit Market.
To be able to describe informal rural credit markets, we apply the Brock and Scheinkman model of a price setting and capacity constrained oligopoly, where firms tacitly collude on monopoly pricing. We generalise the model to allow for third-degree price discrimination. The interval of aggregate lending capacity that supports a counter-intuitively increasing part of the equilibrium price-function is smaller than for the uniform price case.
