Total Factor Productivity of the Japanese Rice Industry.

We calculate partial factor productivity and total factor productivity (TFP) indices for rice production using panel data across 42 Japanese prefectures from 1996 to 2006, and perform panel unit root tests of TFP convergence across prefectures. We find that during this period, the partial factor productivity growth rates for capital, land and materials stagnated at the aggregate national level, as did the TFP growth rate, despite a large increase in labor productivity. We also identify evidence of a convergence in TFP across Japanese prefectures. [ABSTRACT FROM AUTHOR]
