Abstract

This study aims to build upon a previous studies looking at the effects of social norms on women working [Alkhuzam et al., 2023; Bursztyn et al., 2020; Cortés et al., 2022].

Social norms influence individual opinions and behaviours, acting as a reference point when making decisions. Like in much of the world, women remain the dominate providers of childcare in Australia, despite increases in gender equity across other aspects of life. We conduct a study in which individuals’ first and second-order beliefs are elicited, to gauge support for working mothers. First order beliefs are used to infer the social norms, and second order beliefs are used to infer peoples’ belief on these social norms. Our objective is to see whether there are misperceptions of social norms and whether there are gender and SES differences in beliefs. We also aim to understand whether providing participants, who misperceive the social norms, with accurate information about their peers’ opinions can shift individual attitudes towards working mothers. Furthermore, we aim to see whether information treatment has an impact on untargeted related and unrelated beliefs.

Experimental Details

Interventions

Intervention(s)

Our experiment has two stages. In the first stage, we will collect baseline data on beliefs. In the second stage, there will be a control condition and a treatment condition. Using a between-subject design, half of the survey participants, in the second stage, are exposed to treatment.

Intervention (Hidden)

Our experiment in the second stage is a between-subject design.
1) Control: participants are asked to complete the survey (elicitation tasks) in a standard fashion with no information treatment.
2) Treatment: Participants will receive treatment information. In this treatment, participants are provided with information (belief updating) about their peers’ responses to the same questions in an earlier survey round.

Donation: As part of the study, some of the participants will be randomly selected to receive a bonus. Participants will make a decision about whether to donate some of their bonus to a non-profit organisation called Fitted for Work, whose aim is to empower disadvantaged women to achieve economic independence through sustainable work by providing job finding/preparation services.

Primary Outcomes

Primary Outcomes (end points)

Beliefs on targeted social norm questions and untargeted related and unrelated beliefs.
Donation amounts.

Primary Outcomes (explanation)

Research Question: Do Australians correctly perceive the opinions held by others regarding working mothers? Is there gender and SES differences on beliefs? If the norms are misperceived, can information shift individual attitudes? And will information treatments impact related and unrelated beliefs that are not specifically targeted by the information treatment?

Secondary Outcomes

Secondary Outcomes (end points)

Secondary Outcomes (explanation)

Experimental Design

Participants aged between 18 and 35 are recruited to complete our online experiment (developed through Qualtrics and completed on Prolific). This experiment is conducted as a two-stage online survey. In our survey, participants are asked to read a vignette scenario and guess the responses of other females and males living in their area and also provide their own recommendation to the questions presented. In the second survey, half of the participants will be randomly chosen to receive treatment information.

Experimental Design Details

There are two stages. In the first stage, we will collect information about baseline beliefs.

In the second stage, participants are randomised into either the control or treatment group. The survey begins with asking for participants gender and their state/territory of residence. Participants are then asked to read a vignette scenario about two working parents with a three-year-old child, who is currently in bad-quality childcare. The parents believe one of them should reduce their working hours to help with childcare each week until the child begins primary school. Participants are asked to guess what percentage of other females and males would recommend the mother take time off when she earns 50% less, the same, and 50% more than the father. Next, participants are asked for their own recommendation with the same wage differentials. For the treatment group (in the second survey round), participants are provided with the information before asking for their own recommendation. We then ask participants to complete demographic questions.

In both stages, participants complete a series of related and unrelated beliefs questions, asking for their agreement with the given statements, their guess of other Australians opinions and their confidence in their guesses. These related and unrelated beliefs questions have been sourced from the Household, Income and Labour Dynamics in Australia Survey (HILDA).

Our objective is to see whether providing an information treatment will shift individual attitudes compared to the control group. We are also interested in seeing whether this information treatment has a spillover/backfiring effect on related and unrelated beliefs.

Experiment Characteristics

Sample size: planned number of clusters

200 individuals in the first stage. The second stage numbers will be determined based on the first stage data and the preregistration will be updated before data collection in the second stage.

Sample size: planned number of observations

200 individuals in the first round. The second stage numbers will be determined based on the first stage data and the preregistration will be updated before data collection in the second stage.

Sample size (or number of clusters) by treatment arms

The sample size by treatment arms will depend on the results of power calculations using the first stage data. The preregistration will be updated after the first stage data collection with this information before the second stage data collection.
