Gold, and other precious metals, are among the oldest and most widely held commodities used as a hedge against the risk of disruptions in financial markets. The prices of such metals fluctuate substantially, introducing a risk of its own. This paper’s goal is to analyze the risk of investment...

This paper examines the linkages of stock markets across the U.S., Japan and six Asian developing countries: China, India, Indonesia, Malaysia, the Philippines and Thailand over the period January 1, 1993 to December 31, 2012. The volatility spillover is modeled through an asymmetric...

We develop and evaluate analytic and bootstrap bias-corrected maximum likelihood estimators for the shape parameter in the Nakagami distribution. This distribution is widely used in a variety of disciplines, and the corresponding estimator of its scale parameter is trivially unbiased. We find...

By noting that the Hodrick-Prescott filter can be expressed as the solution to a particular regression problem, we are able to show how to construct confidence bands for the filtered time-series. This procedure requires that the data are stationary. The construction of such confidence bands is...

We derive expressions for the first-order bias of the MLE for a Poisson regression model and show how these can be used to adjust the estimator and reduce bias without increasing MSE. The analytic results are supported by Monte Carlo simulations and an empirical application.

We examine the finite sample properties of the maximum likelihood estimator for the binary logit model with random covariates. Analytic expressions for the first-order bias and second-order mean squared error function for the maximum likelihood estimator in this model are derived, and we...

We model the durations between firms’ “Initial Public Offerings” (IPOs) and their subsequent “Seasoned Equity Offerings” (SEOs) in China during the period from 1 January 2001 to 1 July 2006. Duration analysis is applied by using the nonparametric Kaplan-Meier estimator of the hazard...

In this study we suggest a Bayesian approach to fuzzy clustering analysis – the Bayesian fuzzy regression. Bayesian Posterior Odds analysis is employed to select the correct number of clusters for the fuzzy regression analysis. In this study, we use a natural conjugate prior for the...

We show that certain the winning bids for certain ebaY auctions obey Benford’s Law. One implication of this is that it is unlikely that these bids are subject to collusion among bidders, or “shilling” on the part of sellers. Parenthetically, we also show that numbers from the naturally...

We consider the relative merits of various saddlepoint approximations for the c.d.f. of a statistic with a possibly non-normal limit distribution. In addition to the usual Lugannani-Rice approximation we also consider approximations based on higher-order expansions, including the case where the...
