This study aims to estimate job seekers' willingness to pay for job flexibility using a discrete choice experiment approach. This study is coordinated with a company and a job search board in China. In order to investigate the potential influence of Covid and/or the zero-Covid policy implemented by Chinese government, we plan to conduct two waves of experiments, one during the Covid period and one after the giving up of zero-Covid policy.

Experimental Design

Experimental Design
We use a discrete choice experiment approach. We have four types of job characteristics: (1) no flexibility; (2) time flexibility; (3) place flexibility; (4) full flexibility. We also have four positions which are used for recruitment. We planned to do two waves of experiments. One was conducted during the zero-Covid policy period, that is the first half year of 2022, and the second wave is planned to be conducted in March 2023 when the zero-Covid policy by Chinese government has been given up for a couple of months.
Given the four types of job characteristics, we can have three combinations: (1)+(2); (1)+(3) and (1)+(4). We also provide different wage levels. The wage for job with no flexibility is fixed while we randomly assign wages to jobs with time flexibility, place flexibility or full flexibility. We then randomly push the job recruitment advertisement, which includes the three combinations respectively, to the potential job seekers. The job seekers can choose which characteristics they prefer: job with not flexibility and job with time flexibility, place flexibility or full flexibility.
We collect the information for further analysis.

Experiment Characteristics

Sample size: planned number of clusters
21 wage levels.
Sample size: planned number of observations
It actually depends on potential job seekers. Our idea plan is to have around 400 job seekers for each combination of job characteristics.
Sample size (or number of clusters) by treatment arms
It depends on the number of potential job seekers.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
