Box 29502; San Francisco CA 94129 rderickson@PresidioMBA.org Abstract Consumer behavior is complex and pluralistic in nature. Typically, any given individual consumer exhibits more than one type of behavior, depending on stimulus and conditioned, or even genetic, response. For example, a single consuming individual may act one way when consuming “products” or “services” essential for survival, yet in an entirely different way, often seemingly irrational, when it comes to “non-essential” consumption related to social status or pleasure seeking, just to name but two subcategories of so-called “non-essentials.” One has to look at the individual in both isolated and social contexts to begin a study of consumer behavior. Naturally, with a population of many individual consumers, coupled with local and global diversity, comes an even more daunting and intertwined range of behaviors that may appear nearly impenetrable to comprehension, challenging the goal of achieving sustainable consumption on all scales, large and small. A first step in penetrating consumer behavior, with the ultimate goal of developing methods for guiding and achieving sustainable consumption, is to attempt to set forth a system of classification that captures various types of consumer behavior under various sets of influencing circumstances and settings. In doing so, we take a deeper look at the notions of “essential” and “non-essential” consumption. A further step is to recognize and distinguish types of consumers, not just types of behaviors. Thus, in unraveling human consumptive behavior, it is useful to explore humans and inanimate entities, such as a building or automobile, as distinct types of “consumer.” Essentially, humans as well as all products and services are consumers in that they “consume” resources of one type or another, renewable or non-renewable. In this paper, we will distinguish such inanimate consumers as an agricultural product or a clothing item from an airplane, a car, or a building, to list a few examples. Clearly, there are gradations within the general category of inanimate consumer, and these gradations need to be fully examined and understood. Certainly, humans are the agents responsible for designing, constructing, and operating inanimate consumers, but the relationship between the human agent and a building, for example, is quite different from the relationship with an automobile, broadly speaking. With an automobile, the relationship can be much more emotional and serve much more as an extension of the human agent, the ultimate consumer. The nature and nuances of the relationship between the human consumer and various inanimate consumers is crucial to understanding and developing sustainable initiatives. No two relationships are alike, and each requires a separate approach for untangling the roadblocks to sustainability. Building on the work of a multitude of thinkers in the realm of consumer behavior, this paper proposes a classification scheme for understanding human consumptive patterns based on an exploration of: a) the behavior of human consumers under various settings, individually and in a social context, b) the distinction between the human and inanimate consumer, and c) the nature of the relationship between the two types of consumer, with the goal of developing guidance for achieving sustainable consumption.
