Consumption is a key area of study in economics, sociology, marketing, and psychology that examines how individuals, households, and organizations make choices about the goods and services they purchase and use. It focuses on understanding patterns of spending, saving, and investing, as well as the factors that influence consumer behavior such as income level, preferences, demographics, and cultural norms. Consumption research seeks to explain why people make certain purchases, how they allocate their resources, and the effects of consumption on overall economic growth and well-being. This field also explores issues related to advertising, branding, consumer protection, and sustainable consumption practices.
