Abstract
Based on our study “Subjective Stress, Autonomy, and Incentives” (AEARCTR-0003532) we analyze how work arrangements that couple employee autonomy and performance incentives affect workplace stress. In this study, we intend to evaluate individuals’ physiological stress responses by sampling their salivary cortisol. Furthermore, we intend to compare subjective stress appraisals with the physiological response, in order to assess whether individuals potentially misjudge the extent to which a certain situation stresses them.

Primary Outcomes

Primary Outcomes (end points)
Cortisol measured via saliva; Primary appraisals index as well as threat and challenge indices, which comprise the primary appraisal items of the PASA questionnaire (Gaab et al. 2005); Choice of working time (and its difference to optimal working time)
Primary Outcomes (explanation)
All indices are constructed as averages of the respective items.

Secondary Outcomes

Secondary Outcomes (end points)
Pre-task and post-task elicitation of self-reported feelings of stress and well-being; Self-perceived effort exertion; Salivary amylase
Secondary Outcomes (explanation)

Experimental Design

Experimental Design
The design resembles the one described under AEARCTR-0003532. However, it is limited to the four main treatment arms, which vary by the extent of certainty about one’s own performance and the level of working time autonomy. Subjects are randomized into one of the four treatment arms, where the treatment arm characterized neither by autonomy nor performance certainty serves as the main control group. In all treatments, subjects work on a real-effort task adopted from Fliessbach et al. (2007).
During the experiment, we repeatedly sample subjects’ salivary cortisol. Furthermore, we sample salivary amylase and elicit measures of subjective stress and well-being, the appraisal of how stressful a situation is, and track our subjects’ working time choices. We also measure participants’ demographics, personality traits and preferences, such as risk attitudes, uncertainty aversion, and an their willingness to avoid workplace stress, in order to assess whether the individual stress response to working conditions is heterogeneous and whether this heterogeneity is partly determined by these measures.

Experiment Characteristics

Sample size: planned number of clusters
no clusters
Sample size: planned number of observations
We ran power calculations (power 0.8, alpha 0.05) based on the results of the first sessions (71 subjects over 4 treatment arms) and aim at ca. 70 subjects per treatment arm, i.e., 280 subjects in total
Sample size (or number of clusters) by treatment arms
We aim at a balanced design with roughly equal number of participants per treatment arm
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
