This study examines futures price and volatility transmissions among three major wheat production and exporting regions, the United States (US), Canada and the European Union (EU) over the recent six-year study period of 1996 - 2002. The price transmission pattern shows that Canadian prices are...

Copulas provide investors with tools to model the dependence structure of financial products. The choice of copulas plays an important role in successful copula applications. This paper discusses the copula selection problem for the so-called 'D-vine' decomposition from a perspective of the...

The gamma distribution is an important probability distribution in statistics. The maximum likelihood estimator (MLE) of its shape parameter is well known to be considerably biased, so that it has some modified versions. A new modified MLE of the shape for the gamma distribution is proposed in...

In this paper, we study the U.S. aggregate business failures during 1980- 2004 in relation to four macroeconomic variables: aggregate corporate profits, the producer price index, the interest rate, and stock market performance. We argue that aggregate business failures should not be treated as a...

This paper considers one-way flow network formation games in which transmission through a series of agents is subject to decay. We analyze the myopic best-response dynamics of network formation games, occasionally perturbed by state-dependent random noises. Specifically, if an agent is isolated...
