This study examines the estimation of the exchangeable joint distribution when the highest (lowest) and another order statistics are observable. The estimator would be appropriate for the estimation of the valuation distribution of auctions and "order-biased" sampling, such as school student...

We generalize the refinement ordering for well calibrated probability forecasters to the case were the debtors under consideration are not necessarily identical. This ordering is consistent with many well known skill scores used in practice. We also add an illustration using default predictions...

Recurrence relations for integrals that involve the density of multivariate normal distributions are developed. These recursions allow fast computation of the moments of folded and truncated multivariate normal distributions. Besides being numerically efficient, the proposed recursions also...

The classical theory about foreign exchange rate explains its fluctuations as the resulting of a random walk motion. In this paper, such a theory is put into question by performing Brock, Dechert and Scheinkman's (1987) test on the Austrian Schilling - US Dollars exchange rate for the period...

The contribution of this paper is the extension of theoretical and practical applicability in complex systems of a fundamental concept of extreme value theory. More precisely, the paper formulates a stochastic model and establishes the sufficient conditions for evaluating its distribution...

This paper studies the 28 time series of Libor rates, classified in seven maturities and four currencies), during the last 14 years. The analysis was performed using a novel technique in financial economics: the Complexity-Entropy Causality Plane. This planar representation allows the...

This paper considers a problem of asset pricing for case when the short-term interest rate process does not have the markovian property. In this case the price can be determined also by state variables some of that are not observable. In the same time from the practical point of view, the...

This paper suggests a model based on Poisson processes to estimate joint credit losses without the limitations of normality assumptions and non-negative correlation. Idiosyncratic and systematic risks are seen as “shocks” and defaults are driven by a latent variable (loans' lifetimes). The...

This study compares the performance of Prospect Theory versus Stochastic Expected Utility Theory at fitting data on decision making under risk. Both theories incorporate well-known deviations from Expected Utility Maximization such as the Allais paradox or the fourfold pattern of risk attitudes....

In recent years, fractionally-differenced processes have received a great deal of attention due to their flexibility in financial applications with long-memory. This paper revisits the class of generalized fractionally-differenced processes generated by Gegenbauer polynomials and the ARMA...
