Study Notes
Consumer behaviour examines how individuals make decisions to allocate resources, particularly in purchasing goods and services. Consumer Rationality — the assumption that consumers make decisions to maximize their satisfaction based on complete preferences, transitivity, and non-satiation. Example: Choosing between two products based on preference. Utility Maximization — consumers aim to achieve the highest satisfaction with their available resources. Example: Buying a combination of goods that provides the most happiness for their budget. Perfect Information — consumers have all the necessary information to make informed decisions. Example: Knowing all product details before purchasing. Biases — systematic patterns of deviation from norm or rationality in judgment. Example: Anchoring, where initial information influences decisions. Nudge Theory — influencing consumer behavior through indirect suggestions without restricting choices. Example: Arranging healthy foods at eye level to encourage better eating habits. Choice Architecture — designing the way choices are presented to influence decision-making. Example: Default options like automatic enrollment in pension plans.
