A risk-averse person is someone who believes that the smaller the risk, the better, and who wants to be compensated for any additional risk with a sufficient increase in profits. They are contrasted with risk-neutral people, who are indifferent to the size of the risk and evaluate risky behaviors only based on the size of the profits, and risk-lovers, who like the very existence of risk and prefer riskier behaviors if the size of the profits is the same. The idea of risk averseness is the basis of portfolio theory and theories that explain the demand for money.

危険を伴う行動において,危険は小さければ小さいほど良いと考え,危険を追加的に負う場合には,それに見合った十分な収益の増加による補償を望む人々のことをいう。危険の大きさには無関心で,収益の大きさのみで危険を伴う行動を評価する危険中立者や,危険の存在そのものを好み,収益の大きさが同じであればより危険の大きい行動を好む危険愛好者と対比される。危険回避者という考え方は,ポートフォリオ理論や貨幣需要を説明する理論の基礎となっている。
