Resumen
En este artículo se discuten los problemas de identificación que se enfrentan al estimar la función de oferta y la función de demanda de crédito, se justifica la estimación de las variables explicativas de ambas funciones y el análisis de los determinantes del acceso que podrían tener los productores agropecuarios de Costa Rica al crédito. En cada caso la metodología apropiada es discutida.
Cinco diferentes tipos de dificultades surgen en el proceso de inferencia o análisis empírico que se estudiará aquí. Estas dificultades reflejan las características del mercado de préstamos, los defectos e insuficiencias de la recolección de datos y los defectos e deficiencias de la estimación de modelos. Varias de estas dificultades podrían ocurrir simultáneamente, aunque este no es siempre el caso.
This paper discusses the identification problems faced in estimating the supply function and the demand function for credit, justifies the estimation of the explanatory variables of both functions and the analysis of the determinants of the access that Costa Rican agricultural producers could have to credit. In each case the appropriate methodology is discussed. Five different types of difficulties arise in the process of inference or empirical analysis that will be studied here. These difficulties reflect the characteristics of the loan market, the shortcomings and inadequacies of data collection, and the shortcomings and inadequacies of model estimation. Several of these difficulties could occur simultaneously, although this is not always the case.
