We describe a unifying theoretical framework for stakeholder analysis, establishing a rigorous mathematical formulation that can be used to frame both qualitative and quantitative research. Stakeholders are modeled as interactive practices; legitimacy arises through a projection mechanism. Five...

This paper examines an alternative approach to interest rate modeling, in which the nonlinear and random behavior of interest rates is captured by a stochastic differential equation evolving on a curved state space. We consider as candidate state spaces the matrix Lie groups; these offer not...

We advance a unifying theoretical framework for stakeholder analysis by way of a rigorous mathematical formulation that can be used to inform both qualitative and quantitative research. The framework comprises five components contributing to stakeholder salience. Three of these relate to power,...

The credit risk model developed by Hamilton, James and Webber introduces the firm-specific information into the rating transition process through a measure of credit quality of the underlying firm. In this paper, we present an algorithm, for constructing a three-dimensional lattice to implement...

Lattice methods are often used to value derivative instruments. Multinomial lattice methods can in principle converge to the true value of the derivative to very high order. In this paper we describe how very high order multinomial lattices can be constructed and implemented when the SDE...

Banks' internal credit risk assessment may take into account not only publicly available ratings but also internal measures of credit risk. We present a credit rating model of credit risk that permits banks to employ their own risk assessment in addition to public rating information. Banks need...
