Deceptive Advertising (misrepresentation of price or quality) of products has been rampant over the last decades. The increase in such activities is a growing concern for consumer protection agencies as they are subject to limited resources to monitor and prosecute the retailers who adopt deceptive advertising as a marketing strategy. This paper describes a prototype model that addresses the problem of deceptive advertising in the consumer marketplace. The simulation model integrates consumer purchasing behaviour, the behaviour of retailers who adopt and who do not adopt the deceptive advertising, and the behaviour of consumer protection agencies for law enforcement and compliance- promotion strategies. The preliminary results of a few simulation scenarios are discussed.
