Final answer:
The direction of one's gaze can influence decision-making when two items are of equal value, a concept explored in behavioral economics.
Step-by-step explanation:
When two items have equal value, where people look has an effect on their choices. This notion is closely related to behavioral economics, which explores how psychological, social, and cognitive factors influence economic decisions. For instance, when faced with two products of equal value, the availability heuristic might lead a consumer to choose the product they remember more readily, possibly because it's been more heavily advertised or recently discussed in their social circles.
Additionally, the substitution effect is relevant when considering choices between items. This economic principle suggests that as the relative price of one good increases compared to another, consumers will substitute the more expensive item with the less expensive one. Therefore, if two items are perceived to have equal value, a shift in price could significantly sway the decision-making process in favor of the less expensive item.
