Credit Rationing:
A Perspective from New Keynesian Economics
Abigail Rodríguez and Francisco Venegas

This work presented the different concepts of credit rationing proposed by New Keynesian Economics. All of them represent a relevant contribution because they provide complementary elements. It is important to highlight that the precise definition of the concept would require an explanation of why it originates, why it prevails, how it is corrected and the macroeconomic implications it carries. This text has proposed a classification of literature related to credit rationing. As shown, the different contributions can be divided into three basic areas:

  1. Granting of credit oriented towards productive activity, subject to evaluation and financing of investment projects. In general, it is assumed that information is asymmetrical because the credit applicants have greater knowledge of the characteristics of the projects for which they seek financing. This leads to problems of moral risk, adverse selection, monitoring costs and agency costs.
  2. The credit supply and contractual conditions (prices, rates and demands) are influenced by long-term relationships that creditors maintain with their borrowers. There are two opposite approaches. One says that the more solid the relationship (measured by length of duration, number of distinct credit contracts maintained by the parties and available information) the more preferential conditions the client receives. The other says that despite the strength of the relationship, the clients suffer rationing and adverse credit conditions.
  3. Rationing is linked to monetary policy or to the structure of the financial system. In the first case, rationing modifies the results expected by the monetary authority. In the second, the market structure or presence of specialists (financial intermediaries) facilitate access to credit. The availability of resources affects the macroeconomic results through investment and production.

There are various underlying hypotheses for these lines of research and some of them are still being developed. However, given the current macroeconomic context, we believe that the areas of greatest relevance are now analyzing the effects of monetary policy on real economic activity, participation of financial intermediation and the consequences of regulating activities in the banking sector. Although this text has mainly focused on literature that directly addresses the problem of credit rationing, it is useful to note that New Keynesian Economics has extended the analysis of financial markets towards other areas, such as systemic risks associated with activities in the banking sector.
