We introduce the concept of ordinal pattern dependence between time series and show in an explorative study that both types of this dependence show up in real world nancial data. The classical way to capture the leverage e ect in models for stock markets is to assume a negative correlation between the two datasets which is constant in time (e.g. Barndor Nielsen and Shepard (2002)). However, the...

Rework in construction development projects can significantly degrade project cost and schedule performance. In a typical construction development project which involves design and construction, rework in the construction phase could increase construction cost by 10%-15% of the contract price (Burati. 1992, Josephson & Hammerlund 1999, Love & Li 2000). The proportion of money and time spent on ...

A standard explanation ties the phenomenon to the effect a change in market valuation of a firm's equity has on the degree of leverage in its capital structure, with an increase in leverage producing an increase in sto...

We focus on the -nite-sample behavior of heteroskedasticity-consistent covariance matrix estimators and associated quasi-t tests. The estimator most commonly used is that proposed by Halbert White. Its -nite-sample behavior under both homoskedasticity and heteroskedasticity is analyzed using Monte Carlo methods. We also consider two other consistent estimators, namely: the HC3 estimator, which ...

In a recent study by Ginther et al., the probability of receiving a U.S. National Institutes of Health (NIH) RO1 award was related to the applicant’s race/ethnicity. The results indicate black/African-American applicants were 10% less likely than white peers to receive an award, after controlling for background and qualifications. It has generated a widespread debate regarding the unfairness of...

This paper outlines ongoing research that is investigating ways to increase the supply of high quality planting materials for smallholder forestry in the Philippines. A Bayesian Belief Network (BBN) of the nursery sector that had been developed previously by one of the authors was further refined during a planning and implementation workshop for the ACIAR Smallholder Nursery project. The refine...
