In this paper we assess if the financial market liberalization introduced in the beginning of the 1990s in Greece has changed the degree of market development (efficiency) by studying time-varying global Hurst exponents. Our results suggest that changes in financial market liberalization have...

This paper evaluates the loans market in Brazil in the 2003 to 2008 period. It measures diversification and nonperforming loans for Banks credit portfolios. We employ the credit risk bureau database, which classifies loans by sector and risk. Results show an increase in higher risk loans and...

This paper employs a Bayesian stochastic frontier, providing exact inference on both cost and profit efficiencies of the Indian banking sector in the period of 2000-2006. We also test for the inclusion of off-balance sheet data in model specification. The findings suggest that public banks are...

This paper analyzes the efficiency of the Brazilian banking sector over the post-privatization period of 2000-2007. We employ a Bayesian stochastic frontier approach, which provides exact efficiency estimates and confidence intervals and thus, allows an accurate comparison across institutions...

This paper investigates cost, technical and allocative efficiencies for Brazilian banks in the recent period (2000-2007). We use Data Envelopment Analysis (DEA) to compute efficiency scores. Brazilian banks were found to have low levels of economic (cost) efficiency compared to banks in Europe...

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 studies the Brazilian term structure of interest rates and characterises how the term premia have changed over time. We employ a Kalman filter approach, which is extended to take into account regime switches and overlapping forecasts errors. Empirical evidence suggests that term...

This paper investigates cost, technical and allocative efficiency for Brazilian banks in the recent period (2000-2007). The empirical results imply that non-performing loans is an important indicator of efficiency level, as well as market share. Evidence is in favor of the home field advantage...

This paper employs new methods to measure and monitor risk in the Brazilian banking sector. We prove that the option-based risk measure is negatively sensitive to interest rates. As this is an important issue for emerging market economies, the risk measures are built as deviations from mean....
