This study estimates the patterns of marriage premium of male wage in Taiwan over the 90's, focusing on the selectivity of marriage and the endogeneity of wife's labor force participation. The empirical results show that marriage status is evidently selected in male's wage equation. Positive marriage premium existing in male wage over the late 90's is significantly associated with wife's labor supply. Wife's joining labor market brings about favorable effects on husband's wage due to the complementarity of the couple's labor market human capital. Gender division in domestic services is not prevalent in Taiwan, thus wife's working hour does not cause significant unfavorable effects on husband's wage. And the encouragement of wife's access to full-time jobs may be advantageous to husband's wage rate.
