Abstract
Across economies, flexibility of working hours responding to workers' needs is rare, whereas employers' expectations of availability for irregular hours remains common. Against this background, Goldin conjecture emerges, that difference in wages between men and women essentially reflects the difference in flexibility rather than only taste based discrimination. We propose a framed field online experiment with vignettes to test empirically the validity of a conjecture that gender wage gap is in fact merely an inflexibility penalty. We elicit wage premium/penalty due to working time flexibility, manipulating information about who initiated the change in working time arrangements.

Primary Outcomes

Primary Outcomes (end points)
Primary outcome is subject's answer whether wage should change due to change in time flexibility and on how much.

Experimental Design

Experimental Design
We use vignette experiment technique. Our subjects are presented short stories on three fictional characters and a change from regular to flexible working hours. Stories differ between subjects by gender of a character and initiator (worker vs. employer). Participants are asked if and how the change in working hours should affect worker wage.

Randomization Method
Randomization will be provided by the online survey tool used to conduct the experiment.
Randomization Unit

Was the treatment clustered?
No

Experiment Characteristics

Sample size: planned number of clusters
There are no clusters planned
Sample size: planned number of observations
800-900 participants
Sample size (or number of clusters) by treatment arms
There are two dimensions of planned treatments (each with two levels), so for each treatment around 200 participants are planned.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
