結婚，好嗎？—婚姻狀態對男女收入的影響

本研究探討婚姻狀態對男性及女性收入的影響，利用台灣社會變遷調查2001年、2006年及2011年的家庭問卷，並將三期樣本匯集後，採用一般最小平方法(OLS)進行分析。應變數是以個人收入是否為3萬元以上做為區分，而主要自變數是三種不同的婚姻狀態，分別為「單身」、「已婚」和「離婚、喪偶或分居」，為了觀察影響的成因，除了全部樣本的迴歸結果外，也對樣本做了分群迴歸分析。綜合以上迴歸結果，發現不論教育程度、工作地點及年齡大小，台灣已婚男性普遍存在婚姻溢酬，而經歷婚姻對台灣女性的個人收入可能存在負效果，但沒有顯著的影響。內生性及資料問項的不齊全為本文的研究限制。

This study aims to investigate the effect of marriage on income for men and women. I pools the data from Taiwan Social Change Survey of 2001, 2006 and 2011, uses Ordinary Least Squares (OLS) method. Our explained variable is the indicator for personal income higher than $ 30,000 per month. The main explainary variable is marital status which includes Single, Married and Divorced, widowed or separated. For discussing in detail, I not only regress all sample on data, but also separating them by education, work place and age. Based on the similar regression models, I find that the marriage premium exists generally, on married men in Taiwan, no matter his education, work place or age. However, the income of women in Taiwan may suffer from marriage, but the effect is not significant. Due to the data limitation, this paper has some restriction of endogenous problems.
