The Duan Options Pricing Model is an alternative to the Black & Scholes Model (B&S), but considers the heteroskedasticity and the non-normality of the asset-returns. This study analyzes the performance and the characteristics of this model when applied to the Brazilian market, specifically on...

This paper develops a demand model for bank loans with a two-step decision process. In the first step, the agent chooses the financial institution from which she would like to borrow. In the second step, conditioned in the first decision, the agent chooses the desired amount of the loan. The...

This paper aims to compare the interest rates charged by credit unions and banks (commercial and multiple) in order to check whether there are differences between the rates charged for loans without personal assignment and the effects of this difference in interest rates charged by banks in...

This study proposes a new methodology called Canonical FAVAR that incorporates the canonical correlation analysis in the estimation of two-step FAVAR models to obtain more appropriate factors for forecasting. The canonical correlation technique identifies a small number of linear combinations of...

Historical models are being quite used in the value at risk (VaR) estimation due to the fact that many returns of financial assets cannot be described by a theoretical distribution. In these models, each observation of the past can be a possible scenery and for each scenery there is a price for...

Options strategies are combinations of transactions involving options on the same underlying asset or simultaneous positions on those derivatives assets and the underlying asset. Such transactions create new investment opportunities and different risk exposures, leading to specific capital...

This paper analyses the price-concentration relationship for the Brazilian banking industry. Interest rate on loans proxies for price and the Herfindahl-Hirschman index proxies for concentration. A positive price-concentration relationship may be associated with anti-competitive behaviour while...

The Value at Risk calculation for options has a lot of difficulties. The non-normality and the non-linearity of these assets cause sufficient unaccuracy in this measurement, mainly for the parametric models. The purpose of this article is to analyze the results of the VaR estimate for a...

This paper investigates the use of high frequency data in the estimation of daily and intradaily volatility, in order to compute value at risk (VaR) forecasts for the IBOVESPA. GARCH models and deterministic methods for the filtering of seasonal patterns have been used in the computation of...

This work seeks to analyze empirically the coherence of the VaR and the Expected Shortfall by the definition of Artzner et al. (1997) at the Brazilian Stock Market (Bovespa), calculated with three methodologies: the historical simulation, the analytical approach with EWMA volatility from...
