Experimental Design
The experimental design aims at identifying the workers’ WTP pay for the two job tasks: team responsibility and decision-making. Additionally, I plan to analyze workers' willingness to pay for other job attributes. The key features of the experimental design follows Maestas et al. (2023).
Each respondent participates in ten stated-preference experiments. In each experiment, survey respondents are asked to select between two jobs (A and B), each defined by a partially varying set of job attributes and wages.
For each respondent, I define a baseline job around which job attributes would vary. The baseline job is the respondent’s current job in order to generate hypothetical jobs that would appear realistic to the respondent. For this purpose, the respondents are asked about their current occupation, job attributes and wage prior to the discrete choice experiment. The five job attributes vary when selected and the wage always varies. In the following, I describe how I create the variation.
Starting from the respondent’s baseline job, I create hypothetical Job A and Job B by randomly selecting two non-wage attributes to vary across the two hypothetical jobs. Within each of the two randomly selected attributes, attribute values are chosen at random sequentially, first for Job A and then for Job B without replacement.
In every job choice, respondents see two jobs next to each other where two randomly selected job attributes and the monthly wage vary. Those three attributes are marked in red and all the other job attributes are the same as in their current job. The respondents were asked to select “Job A” or “Job B.”
(For details on the mapping between survey questions and discrete choice attributes, as well as the random wage generation, see the pre-analysis plan.)
