Journal of Marketing Research and Case Studies 10 not decay due to external factors after purchasing the product. Experimental Setup In this study, our primary aim is to assess the efficiency and profitability of different marketing strategies through simulation experiments. Each experiment, which consists of 20 time steps, is replicated 100 times. In each experiment different parameter setups are governed, in order to monitor the directions and the magnitude of effects of different marketing strategies employed by the company. Each experiment is performed two times, when WOM influence is in effect and not in effect in order to evaluate the importance of WOM effect. The first set of experiments is conducted in the presence of WOM. The parameters that remain the same in all our experiments are shown in Table1: Table1: Model Parameter Values There are five different decision variables that affect the buying decision of the consumer. Price, promotion, two design parameters of the product and number of opinion leaders the company chooses to collaborate with. The simulations are run in order to monitor the effects of different product design, price, promotion and opinion leader strategies on profit of the company. In the
