This paper proposes a novel way to model a network of firm-bank and bank-bank interrelationships using a unique dataset for the Brazilian economy. We show that distress originating from firms can be propagated through the interbank network. Furthermore, we present evidence that the distribution...

In this paper we present systemic risk measures based on contingent claims approach, banking sector multivariate density and cluster analysis. These indicators aim to capture credit risk stress and its potential to become systemic. The proposed measures capture not only individual bank...

This paper presents measures for the mitigation of systemic risk adopted in the Brazilian Payment System, and payments processed by this system are analyzed in order to identify potential sources of systemic risk. Measures for the mitigation of systemic risk within the Brazilian Payment System...

In this paper we examine the relation between dollar-real exchange rate volatility implied in option prices and subsequent realized volatility, in the period of February 1999 to June 2000. Our results are in line with recent literature, suggesting that the implied volatility obtained from a...

Within a mean-variance model we analyze the problem of decentralized portfolio management. We find the solution for the optimal portfolio allocation for a head trader operating in <i>n</i> different markets, which is called the optimal centralized portfolio. However, as there are many traders...

This paper presents a method for extracting risk neutral densities for exchange rate options. Implied volatility may be used as a forecast for future volatility and the predicted density to assess the future evolution of market expectations regarding prices in financial market. Implied skewness...

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.

This paper examines the information content of COPOM decisions to change or to leave unchanged monetary policy by estimating the responses of the term structure to changes in the target for interest rates on COPOM meeting days. Within an event-study approach the evidence suggests that market...

This paper examines the empirical evidence that official interventions are associated with periods of high predictability in exchange rate markets. We employ a block bootstrap methodology to build critical values for the Variance Ratio statistics and test for predictability within moving windows...
