This paper presents empirical evidence of short and long-run predictability in stock returns for European transition economies. We employ Variance Ratios with a bootstrap methodology to test for short-run predictability, which is present in most countries. We also estimate Hurst exponents to...

The objective of this paper is twofold. The first is to incorporate mental accounting, loss aversion, asymmetric risk-taking behavior, and probability weighting in a multi-period portfolio optimization for individual investors. While these behavioral biases have previously been identified in the...

This paper examines the impact on Brazilian stocks following American Depositary Receipts (ADRs) listing in the U.S. stock markets. Evidence suggests that a systematic change has taken place in the post-listing period as the multivariate variance ratio statistics have significantly decreased if...

Standard models of moral hazard predict a negative relationship between risk and incentives; however empirical studies on mutual funds present mixed results. In this paper, we propose a behavioral principal-agent model in the context of professional managers, focusing on active and passive...

This work examines the determinants of the capital structure of Brazilian companies between the years 2000 and 2009. Based on quantile regression model and on the comparison with conventional models (least squares and fixed effects), the work provides better understanding of capital structure to...

This study investigates to which extent results produced by a single frontier model are reliable, based on the application of data envelopment analysis and stochastic frontier approach to a sample of Chinese local banks. Our findings show they do produce a consistent trend on efficiency scores...

This paper consists of an empirical investigation of Brazilian banks' profitability determinants. The panel data is composed of quarterly information for 71 banks between the first quarter of 2002 and the second quarter of 2012. Using data from the Brazilian banking system, we study the...

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...
