Consumer purchasing decision making has been of great interest to researchers and practitioners for improving strategic marketing policies and gaining a competitive advantage in the market. Traditional market models generally concentrate on single individuals rather than taking social interactions into account. However, individuals are tied to one another with invisible bonds and the influence an individual receives from others, affects her purchasing decision which is known as word of mouth (WOM) effect. In this process, some people have greater influence on other consumers‟ buying decisions, which are known as opinion leaders. A new evolving modeling approach, agent-based modeling enables researchers to build models where individual entities and their interactions are directly represented. In this study we aim to build an agent-based simulation model for a technological product in a monopolistic artificial market. In particular we will try to assess the efficiency and profitability of different marketing strategies consisting of different price, promotion, quality levels and different number of targeted opinion leaders where consumer are subject to WOM effects . The experiments are also applied for cases where WOM is not present, to effectively evaluate WOM importance in a market. Independent of WOM presence, increasing the price of an average quality product is found to be the most significant and increasing the promotion intensity is found to be the second most significant factor affecting the profit of the company. Also, it is found that the market environment is more sensitive to marginal cost of quality when compared to marginal cost of collaborating with an opinion leader.| Keywords : Consumer network, word of mouth, marketing strategy, agent based modeling.
