Are Commercial Fishers Risk-Lovers?
通过瑞典商业渔民的选择实验,发现仅48%的渔民可视为风险中性,26%适度风险厌恶,26%强烈风险厌恶,且渔业收入占比越高越倾向风险中性。
<i>Fishers are risk-averse according to most empirical studies, while expected-utility theory predicts risk neutrality even for sizable stakes. We test this prediction using data from a stated-choice experiment with Swedish commercial fishers. Our results show that only 48% of the fishers can be broadly characterized as risk-neutral, while 26% are modestly risk-averse, and 26% are strongly risk-averse. Fishers are more risk-neutral the higher the fraction of their household’s income comes from fishing. Sensitivity testing implies that modest stake decisions like a few days of fishing are not influenced by wealth level.</i>
