The gender wage gap is a global issue that impacts women of every country, race, and age. One potential factor explaining the gender wage gap is a difference between how men and women approach and conduct negotiation over their wages. To determine the influence of gender differences in wage negotiation, we create an online laboratory experiment to induce behavior consistent with real world wage negotiation settings.

Experimental Design

Experimental Design
We conduct an online experiment where randomly matched pairs of ‘Employers’ and ‘Employees’ negotiate how to split joint earnings from an incentivized task. Participants only known the gender and competency of their match on the task. Participants receive earning based on their negotiated split and their joint success on the task.
Experimental Design Details
Participants are recruited to participate in an online experiment. Once consent and instructions are given, participants are randomly assigned the role of ‘Employer’ or ‘Employee’ and stay in that role for the entirety of the study. Participants then are asked to indicate the gender they most closely identify with (‘Women/Female’ or ‘Man/Male’). They then conduct a preliminary task of counting the number of 1s in matrices. Pairs of Employers and Employees are then randomly match and their gender and competency on the preliminary task is given to their matched participant. The matched pair is then given three minutes to decide how they want to split earning (based on a secondary task). After the matched pair negotiates how to split earning, then they each enter into a secondary task where they count the number of 1s in matrices individually. Participants are paid through an Amazon gift card based on their negotiated splits and number of matrices correctly counted by themselves and their match. After the study, participants complete a survey where they indicate how well they belief they did in the study compared to others and gender differences in success in the study. Survey questions also gather risk preferences, donations, and socioeconomic and demographic information.
