This article uses data from 2008-10 to analyze parental leave policies in twenty-one European countries and their influence on men's behavior. It examines entitlement characteristics, such as nontransferability, duration, payment, compulsory period, and other policies to assess their effect on the proportion of leave men use out of the total parental leave in each country. The findings, which suggest that a large majority of men take nontransferable and highly paid leave, and a small minority take other types, provide the basis for developing the Parental Leave Equality Index (PLEI). PLEI ranks countries by the degree to which parental leave policies reinforce or diminish the gendered division of labor. Results indicate that although Iceland's parental leave policies do the most to advance gender equity, no country has equal, nontransferable, and well-paid leave for each parent. This policy arrangement would be a precondition to men's and women's equal participation in childcare.
