Source Dependence in Effort Provision
通过两个实验，研究了人们在付出努力时对不确定性的来源（熟悉或不熟悉）的依赖，发现人们对不熟悉来源的厌恶程度随概率变化，且努力对概率的敏感性更低。
Abstract We examine source dependence in the setting of effort provision. Our first experiment elicits preference over uncertain piece rate schemes to perform a real‐effort task. Our second experiment elicits effort after receiving an uncertain gift. We vary the probability of winning and the familiarity of natural sources of uncertainty. We show that subjects are averse to unfamiliar sources for moderate or high probability, but less so for low probability. Moreover, effort exhibits more insensitivity to the probability under the unfamiliar source compared with the familiar source. Our findings support the validity and generalizability of source dependence in applied settings.
