A number of papers predict the imminent demise of currency use in transactions while some make a case for its continued use due to its distinctive feature of anonymity. Notwithstanding the latter, this paper shows on both theoretical and empirical grounds, that cash use is sustainable for the...

The purpose of this Feature is to critically examine and to contribute to the burgeoning multi disciplinary literature on markets as complex adaptive systems (CAS). Three economists, Robert Axtell, Steven Durlauf and Arthur Robson who have distinguished themselves as pioneers in different...

We develop a Nash game on the adoption of a new EFTPOS (Electronic Fund Transfer at Point of Sale) card payment media given cash is dispensed by a competitive ATM (Automated Teller Machine) network. Equilibrium conditions when cash and card use coexist entail a specific relationship between the...

The work of John von Neumann in the 1940's on self-reproducing machines as models for biological systems and self-organized complexity provides the computational legacy for CAS. Following this, the major hypothesis emanating from Wolfram (1984), Langton (1992, 1994), Kaufmann (1993) and Casti...
