In this paper I give a tentative assessment of the methodological status of agent based simulations. I first show under which conditions ABS can be a complement to traditional modelling. I then consider whether they can be held as a sound methodology of their own. Various topics relevant to the...

This open access book examines the methodological complications of using complexity science concepts within the social science domain. The opening chapters take the reader on a tour through the development of simulation methodologies in the fields of artificial life and population biology, then...

In the natural sciences, computational methods have become a central part of the research process. In disciplines as diverse as physics, cosmology, chemistry, and pharmacy, computer-based modeling drives scientific progress and has become a standard tool for scientific research (Morrison 2015)....

Critiques of Neoclassical Economics extend, unsurprisingly, to its mathematical structure. The discussion has largely focused on General Equilibrium Theory (GET), a formalism developed by Léon Walras over a century ago. Internally consistent, but highly unrealistic, GET lacks predictive power,...

This article surveys computational approaches to classical-Marxian economics. These approaches include a range of techniques - such as numerical simulations, agent-based models, and Monte Carlo methods - and cover many areas within the classical-Marxian tradition. We focus on three major themes...
