This study provides new evidence on the relationship between abnormal loan growth and banks´ risk taking behavior, using data from a rich panel of Colombian financial institutions. We show that abnormal credit growth during a prolonged period of time leads to an increase in banks´ riskiness,...

In this paper, we study the empirical relationship between credit funding sources and the financial vulnerability of the Colombian banking system. We propose a statistical model to measure and predict banking-fragility episodes associated with credit funding sources classified into retail...
