Description
This paper attempts to investigate how differences of height, education and age within a coupleinfluence evaluation about partner. Further, this paper explore the effect of differences changedbefore and after marriage. For this purpose, monthly web-site surveys were conducted tocollect the individual level data of unmarried persons who having plan to get married withboy/girl friends. Based on the collected data covering the period from March 2012 to March2015, through the Panel data analysis, we found as; (1) gaps of height and education reducedquarrel with partner after the marriage. (2) Further, quarrel lowered the evaluation about thepartner. Hence, there is indirect positive effect through quarrel on evaluation about partners. (3)However, after controlling the indirect effect through quarrel, gaps of height and educationlowered the evaluation about partner which is considered as the direct negative effect on theevaluation. (4) considering these results jointly indicated that effect of 1 year difference ofeducation on the evaluation is equivalent to that of 4.27 cm difference of height. Assuming thatgap of height and education enhanced division of labor within a household, combined resultsimplied that the division of labor reduce interaction between wife and husband and so avoid thequarrel. This in turn improve evaluation about partner. However, reduction in interactionbetween husband and wife increased psychological distance between them, resulting in loweringthe evaluation about the partner. The negative effect of the gap on the evaluation is far largerthan the positive one.
