Abstract:

Risk-sensitivity theory, which is based on experimental examination of the foraging behavior of animals, proposes that decision makers shift from risk aversion to risk preference in situations of need. As a biological theory of decision making, predications based on risk sensitivity theory has been supported by both animal studies and studies involve human participants. Existing evidence suggests that risk-sensitivity theory can account for various patterns of decision-making in a wide range of domains. It’s necessary to provide a systematic review of risk-sensitivity theory, including its theoretical speculation, main arguments, and development of mathematical models. Distinctions among risk sensitivity theory and other well- established theories were also speculated in consideration of the reference point. Risk-sensitivity theory contributes to the literature as it provides additional explanations for shifts in individuals’ risk taking tendencies under a wide range of situational factors, including changes in economic inequality and power.

Key words: Risk-sensitivity theory, need, reference point, economic inequality, power
