The Sinai Peninsula is a vital part of the Arab Republic of Egypt, geographically and historically. Its uniqueness and diversity of nature are reflected in its place-names, including both physical and human (cultural) features. The objectives of this study are to: (1) construct a digital geo-database of place-names; (2) classify the collected names...

For politicians, to promote intended messages to different groups of individuals, they could employ strategic individuals called “informed agents.” The aim of this article is to explore and measure the impact of two competing groups of informed agents on opinion dynamics within a society exposed to two extreme opinions. Thus, an agent-based model i...

Purpose In a dynamic environment, understanding the consumer’s behavior in an online market is critical for the development of online retailers’ strategies. In Egypt, although the number of internet users is growing rapidly, online shopping is at an early stage of development. In addition, there is a lack of knowledge about the behavior of Egyptian...

Administrative corruption is a pervasive phenomenon that persists around the world regardless of the level of the country’s development. It has been approached by various modeling techniques evolving out of different backgrounds. The most recent technique used is agent-based modeling which possesses analytical tools that reflect the heterogeneity a...

This paper investigates the effect of different levels of rationality on the Lucas-Islands model of economic behaviour. In particular, this is studied through the use of Agent-based Computational Economics, where individual economic agents are represented by separate computational entities in an interacting computer simulation. Three different econ...

The COVID-19 crisis has considerably affected consumers behavior and led to an increase in the share of electronic commerce. Understanding factors making Internet users continue to purchase their products from websites is essential for the prosperity of electronic commerce. This study empirically examines the relationships between seven factors and...

We study asset pricing dynamics in artificial financial markets model. The financial market is populated with agents following two heterogeneous trading beliefs, the technical and the fundamental prediction rules. Agents switch between trading rules with respect to their past performance. The agents are loss averse over asset price fluctuations. Lo...

In this article asset pricing dynamics in artificial financial markets model is studied. The financial market is populated with two heterogeneous beliefs of the traders; technical trading rule and fundamental trading rule. The agents are loss averse over asset prices fluctuations.

This paper presents an agent-based computational economics model (ACE) to study demand-pull and cost-push inflation. Moreover, it studies the effect of different levels of rationality on the equilibrium price and unemployment rate. The model examines three different economies. In the first economy workers choose firms randomly, in the second econom...
