National and regional wage curves in Japan 1981-2001

There is evidence in many countries of an inverse relationship between the real wages paid to workers and the unemployment rate in their local labor market, a so-called wage curve. However, the evidence to date for Japan has been rather limited. In this paper, we estimate wage curves for Japan using pooled cross-section time-series data from 1981 until 2001. The presence of a wage curve is confirmed. The wage curve has become slightly more elastic after the bubble economy of the 1980s than it was in the pre-bubble and mid-bubble period. The unemployment elasticity of pay is greater for males than for females. We also estimate regional wage curves using time-series data. The male wage curve elasticity is larger in the northern regions of Hokkaido and Tohoku and the western region of Shikoku, while it is smaller in the central regions of Hokuriku, Tokai and Kinki
