This paper contrasts married couples perceptions of unpaid work with local currency theory. To evaluate unpaid work, many researchers adopt the monetary evaluation method. The monetary evaluation method has the subjects nominate a fictitious sum of money to represent how much they think unpaid work is worth. This method is not realistic, because it does not take into consideration time spent or work done by unpaid workers, who are generally women. This study uses local currency theories on time and work as a base to evaluate unpaid workers worth. We conducted a time use survey of working couples residing in Tokyo, 2000. The survey questionnaire was based on local currency theory. We clarified a relationship between the subject's evaluation of local currency theory and their unpaid work and time. The main results from this study were 1) Most important factor about the evaluation of unpaid work was the wives' employment type; 2) The husband of full-time employed wives evaluated unpaid work highly.
