RESUMO

The aim of this study is to identify the variables that affect borrower´s decision-making process through the estimation of loan demand equations. This research is relevant not only for market practitioners, but also to academics and to policy-makers, concerned with the evaluation of possible impacts of decision on the economic environment and on the agent´s behavior. Traditional models for demand estimation make unreasonable and very restrictive assumptions to estimate the parameters of interest. Generalized Linear Latent and Mixed Models (GLLAMM) constitute a class of models that includes the traditional Generalized Linear Models (GLM) and Generalized Linear Mixed Models (GLMM), which offer more flexibility and they are particularly suitable to situations that combine discrete choice with continuous decisions. Therefore, we can estimate individual equation for each bank simultaneously. This class of models was applied to study the demand for bank loans using a rich dataset provided by the Central Bank?s Credit Risk Bureau. Among the analyzed variables, the loan maturity and the credit risk classification were important in the bank choice while warranties were important in the decision related to the amount borrowed. Moreover, we could also identify specific market segments for some banks. The flexibility of this class of models was also used to identify the factors affecting the demand for overnight funds by commercial banks. This model overcomes overdispersion problems caused by excess of zeros found in the dataset. Additionally, we identified the direct and indirect effects of rediscount rate through the inclusion of random effects in the intercept (incorporating specific effects for each bank) and other coefficients (identifying individual behavior of each bank regarding the same stimuli).
