Periods of Financial Stability are associated to low bank efficiency and high non-performing loans in credit portfolios. Therefore, this paper studies the relationship between bank efficiency and non-performing loans. To evaluate the bank efficiency, we employ a Data Envelopment Analysis. We...

This paper presents an empirical analysis of the Brazilian interbank network structure. The Brazilian interbank market clearly presents a topology that is compatible to the free-scale networks. This market is characterized by money centers, which have exposures to many banks and are the most...

In this work we measure the evolution of the long-range dependence phenomenon of returns and volatilities of nominal British exchange rates (British pound against US dollar) futures contracts negotiated on the Chicago Mercantile Exchange from 1986 to 2004. The measurement employs the R/S classic...

Recent literature has focused on the study of systemic risk in complex networks. It is clear now, after the crisis of 2008, that the aggregate behavior of the interaction among agents is not straightforward and it is very difficult to predict. Contributing to this debate, this paper shows that...

This paper compares the forecast precision of the Functional Signal plus Noise (FSN), the Dynamic Nelson-Siegel (DL), and a random walk model. The empirical results suggest that both outperform the random walk at short horizons (one-month) and that the the FSN model outperforms the DL at the...

This paper aims to study the effect of banking competition on Latin American banks' risk-taking and whether capitalization and size changes this relationship. We conclude that: (1) competition affects risk in a non-linear manner: high/low (average) competition are related to more (less)...

This paper employs a general equilibrium approach to model the Brazilian financial system. We show that the model is able to replicate the main characteristics of the data and to predict short-term trends. The model is calibrated for the 2002-2006 period. Empirical results suggest that the...

This paper investigates the effects of monetary policy over banks' loans growth and non-performing loans for the recent period in Brazil. We contribute to the literature on bank lending and risk taking channel by showing that during periods of loosening/tightening monetary policy, banks...
