The objective of this article is to discuss a new approach to control for the environment when one estimates efficiency by the stochastic frontier model. By introducing geographical weights and estimating local frontiers for each US saving bank for 2001-09, we find that bank technical...

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 presents empirical evidence suggesting that the degree of long-range dependence in interest rates depends on the conduct of monetary policy. We study the term structure of interest rates for the US and find evidence that global Hurst exponents change dramatically according to Chairman...

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 proposes a model to conduct macro stress test of credit risk for the banking system based on scenario analysis. We employ an original bank level data set with disaggregated credit loans for business and consumer loans. The results corroborate the presence of a strong procyclical...

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...

Using a sample of 495 Latin American banks over the period 2001-2008, this paper investigates how bank concentration influences cost and profit efficiency. We calculate scale efficiency to assess whether these banks are close to their optimal size. We find that banks are more inefficient in...
