An important but overlooked cost of payments in retailing is the cost on checkout cashiers. This paper examines the compensating wage differential that cashiers require to handle payments in cash. First, a multicountry panel data study shows that cashier wages increase with retail cash usage, which is consistent with cashiers requiring compensation to handle cash. Second, in a discrete choice experiment where supermarket cashiers chose between collecting card and cash payments, eight of 10 cashiers preferred card to cash. Among those who preferred card, the median cashier required a wage premium of S$37.50 (US$27) a month to handle cash. The premium was lower among cashiers who are local, less risk averse, and younger. Third, in a laboratory study, subjects traded off earnings against stress. With higher frequency of cash payments, high earners experienced greater physiological stress than low earners. Earnings also increased with abilities in arithmetic and coping with stress. Collectively, these studies show that cashiers require higher wages to handle cash payments, in part due to higher stress. We offer policy, managerial, and research implications for job design, payment systems, and workplace stress.

现金成本：出纳员的证据

零售中一个重要但被忽视的支付成本是收银员的成本。本文研究了收银员处理现金支付所需的补偿性工资差异。首先，一项多国面板数据研究表明，收银员的工资随着零售现金的使用而增加，这与收银员需要补偿以处理现金是一致的。其次，在离散选择实验中，超市收银员在收卡和现金支付之间进行选择，10 名收银员中有 8 名更喜欢刷卡而不是现金。在那些喜欢刷卡的人中，收银员需要每月支付 37.50 新元（27 美元）的工资溢价来处理现金。在本地、风险厌恶程度较低和更年轻的收银员中，溢价较低。第三，在一项实验室研究中，受试者在收入与压力之间进行权衡。随着现金支付频率的提高，高收入者比低收入者承受更大的生理压力。收入也随着算术和应对压力的能力而增加。总的来说，这些研究表明，收银员需要更高的工资来处理现金支付，部分原因是压力更大。我们为工作设计、支付系统和工作场所压力提供政策、管理和研究影响。
