要旨Abstract

 この論文の目的は,1992年と2007年に同一質問票で調査されたデータを用いて,労働組合の経済効果と未組織労働者の態度の変化を分析することにある.分析の結果,以下のような変化が浮き彫りとなった.第1に,労働組合の賃金効果は1992年には観察されなかったのに対して,2007年には男性に関して賃金プレミアムがみられるようになった.ただし,女性に関しては観察されない.第2に,労働組合の発言効果に関しても,1992年にはみられなかったものが,2007年には男性の転職希望(および部分的に仕事不満足度)を引き下げるようになった.ただし,女性に関しては,そうした発言効果はみられない.第3に,男性の未組織労働者の間で組合の組織化支持が高まっている.ただし,女性の未組織労働者の組織化支持の上昇は男性に比べてわずかである.しかも,職場に発言型従業員組織が存在すると,女性の組合への支持は,それにほぼ代替されることで低下してしまう.

 Using microdata derived from the same questionnaire surveys conducted in 1992 and 2007, this paper examines changes in the economic effects of labor unions and attitudes toward unionization among nonunion workers. The main findings are as follows. First, while no union wage effects were observed in 1992, a wage premium for male workers was found in 2007. However, no change was observed for female workers. Second, with regard to union voice effects, no such effect was evident in 1992, but in 2007, a decline among men in the propensity for voluntary quitting (and, to some extent, job satisfaction) was found. In contrast, among women, no such union voice effects could be detected. Third, among male nonunion workers, support for unionization had increased between 1992 and 2007. On other hand, the increase in support for unionization among female nonunion workers was scant when compared with that for their male counterparts. Furthermore, if there were other, nonunion forms of representing employees' vice at the workplace, this largely substituted for female support for unionization.
