Abstract
Research on inequality aversion has been largely focused on the unequal distribution of monetary payment. However, inequality in naturally occurring environments can take many different forms. One important example of this is the unequal working load. In organizations, employees may receive the same salary but unequal working load. This project compares the attitudes towards inequality in these two domains.

Experimental Design
Experimental Design
Our design is a variation of the ultimatum game where one worker propose how to allocate the tasks (or payment), the other decides whether to accept it. When accepted, both will work on the task (or receive the payment) as proposed.
