Purpose – Discusses why it is necessary to align a mathematical model with the organization in order to achieve the desired results. The structure of a model's input must fit with the structure of data collection in the firm, and the output must be consistent with the decision structure....

Purpose – To contrast the different factors that can determine the level of debt of firms by means of panel data methodology. Design/methodology/approach – The variables used in the study are: size, generated resources, level of warrants, debt cost, growth opportunities, and reputation. Six...

Purpose – To: evaluate Prospect Theory and Cumulative Prospect Theory as functional models of decision making and risk within various contexts; compare and analyze risk models and decision‐making models; evaluate models of stock risk developed by Robert Engle and related models; establish...

Purpose – To: evaluate Prospect Theory and Cumulative Prospect Theory as functional models of decision making and risk within various contexts; compare and analyze risk models and decision‐making models; evaluate models of stock risk developed by Robert Engle and related models; establish...

Purpose – The purposes of this article are to evaluate models of stock market risk developed by Robert Engle, and related models (ARCH, GARCH, VAR, etc.); to establish whether prospect theory, cumulative prospect theory, expected utility theory, and market‐risk models (ARCH, GARCH, VAR,...

Purpose – The purpose of this paper is to illustrate the expressive power of Wald's maximin model and the mathematical modeling effort requisite in its application in decision under severe uncertainty. Design/methodology/approach – Decision making under severe uncertainty is art as well as...

Purpose – The purpose of this paper is to clarify a number of important facts about info‐gap decision theory. Design/methodology/approach – Theorems are put forward to rebut claims made about info‐gap decision theory in papers published in this journal and elsewhere. Findings –...

Purpose – This study aims to examine the role of product attributes, applying the multi‐attribute model, on consumers' decisions to download digital music via unauthorised sources in the UK. Design/methodology/approach – The data were collected through an online survey. Consumer choice was...

This textbook introduces readers to essential tools, techniques and methods for intertemporal and strategic modeling in economics. It presents a variety of analytical models covering both dynamic processes and strategic interaction. Students will learn the basic mechanisms associated with the...
