在一些实验中，参与者做出多个决定;这个功能有助于在紧凑的会话过程中收集大量的激励数据。一个保守的支付方案是为每一个决定的结果支付。另一种方法是只为所做选择的一个子集的结果支付，将这个选择的风险金额乘以以补偿该选择的结果被提取以获得回报的可能性降低。这种“付一个”的方法可以帮助避免财富效应，对冲和破产的考虑。第三种方法是只为一部分参与者的选择付费，从而最大限度地降低交易成本。虽然各种支付方法之间的差异的证据是混合的，但总的来说，它表明，只支付一部分期间或个人的费用至少与“支付所有费用”的方法一样有效，而且很可能更有效。并进一步讨论了在设计实验时如何选择最佳的激励结构.

In some experiments participants make multiple decisions; this feature facilitates gathering a considerable amount of incentivized data over the course of a compact session. A conservative payment scheme is to pay for the outcome from every decision made. An alternative approach is to pay for the outcome of only a subset of the choices made, with the amount at stake for this choice multiplied to compensate for the decreased likelihood of that choice's outcome being drawn for payoff. This "pay one" approach can help to avoid wealth effects, hedging, and bankruptcy considerations. A third method is to pay only a subset of the participants for their choices, thereby minimizing transactions costs. While the evidence on differences across payment methods is mixed, overall it suggests that paying for only a subset of periods or individuals is at least as effective as the "pay all" approach and can well be more effective. We further the discussion about how to best choose an incentive structure when designing an experiment. (C) 2016 Elsevier B.V. All rights reserved.
