Experimental Design

The laboratory experiment consists of three stages: Worker Stage, Beliefs Stage, and Hiring Stage. In the Worker Stage, 20 workers will be recruited to take a math task that will be used as the basis for Beliefs Stage and Hiring Stage decisions. In the Beliefs Stage, beliefs about men's and women's performance on the math task will be elicited. In the Hiring Stage, managers will hire workers for three different jobs based on math task performance. Further details about each stage are explained in the following sections.

Worker Stage:

20 participants, 10 men and 10 women, will perform a math task. Before the math task, we ask for demographic information, including age, gender, major, and year. The math task, itself, is the addition of five two-digit numbers. Participants have 5 minutes to answer as many math questions as possible. Payment for the math task is piece-rate, where each correctly answered question is worth $1.00. Participants will be told prior to participating that their demographic information and performance will be shown to other people in a later study.

Beliefs Stage:

In the second part of the experiment, participants will be recruited to tell us their beliefs about performance of others on the math task. Half the participants will tell us their beliefs about the distribution of men's performance on the math task and half the participants will tell us their beliefs about the distribution of women's performance on the math task. Participants will be randomly assigned to either the men questions or women questions.

We will elicit beliefs using a Multiple Price List about the probability that one randomly chosen man/woman in the worker stage is in the bottom 25th, bottom 50th, and top 25th quantiles of performance in the population of workers. This question will be: What is the probability that a randomly chosen (fe)male worker performs in the top 5 of total workers' performance? We will ask three questions where we replace "top 5" with "bottom 5" and "bottom 10".

Hiring Stage:

In the hiring stage, managers to hire from the previous pool of workers. There are three different "jobs" for which managers will hire. For the first job, managers will get paid if the worker they hire "passed" the math task. Passing the math task means that the worker did not score in the bottom 25th percentile of performance on the math task. For the second job, managers will get paid if the worker is excellent on the math task. Excellence means that the worker scored in the top 25th percentile of performance on the math task. The last job is a piece-rate payment for the manager based on the performance of the worker. This means the manager will receive $1.00 for each question the worker answered correctly. For each of these three questions, the manager will choose between one randomly selected man and one randomly selected woman from the worker population.
