Rapidly declining gasoline prices from their record high during the summer of 2008, while ethanol prices remained relatively high, made it difficult for many bio-fuel policy modelers to fully explain the impacts of U.S. bio-fuel policies on fuel prices. Using profit-maximization models for...

The DSD method for modeling propagating detonation is based on three elements: (1) a subscale theory of multi-dimensional detonation that treats the detonation as a front whose dynamics depends only on metrics of the front (such as curvature, etc.), (2) high-resolution, direct numerical...

Cost or performance targets for new bit technologies can be established with the aid of a drilling cost model. In this paper the authors make simplifying assumptions in a detailed drilling cost model that reduce the comparison of two technologies to a linear function of relative cost and...

Econometricians frequently propose parametric models which are contingent on an underlying assumption of rational economic agents maximizing their utility. Accurate estimation of the parameters of these models depends on using data disaggregated to the level of the actual agents, usually...

The population dynamics underlying the diffusion of ideas hold many qualitative similarities to those involved in the spread of infections. In spite of much suggestive evidence this analogy is hardly ever quantified in useful ways. The standard benefit of modeling epidemics is the ability to...

This paper broadens perpetuity gain to level (GL) research by analyzing the role of growth within the capital structure model (CSM) formalized by Hull (2007). We contrast the cost of using internal equity versus external equity when expanding a firm's assets. Contrary to pecking order theory, we...

Electricity markets are currently evolving to accommodate large scale penetration of wind generation. In this research, potential changes to the classification and role of windgenerators in the Single Electricity Market (SEM), the market for Northern Ireland and the Republic of Ireland, are...

Ranked preference data arise when a set of judges rank, in order of their preference, a set of objects. Such data arise in preferential voting systems and market research surveys. Covariate data associated with the judges are also often recorded. Such covariate data should be used in conjunction...

The authors of the article point out that the theory of economics has failed to yield a solid theoretical background in such critical situations as the transformational period of post-communist economies and the period of the current financial and economic crisis. While classical liberal or...

This paper develops multivariate methods for analyzing (1) effects of socioeconomic variables on the total fertility rate and its components and (2) effects of socioeconomic variables on the trend in the total fertility rate and its components. For the multivariate methods to be applicable, the...
