These include information sharing devices, such as joint labor-management committees(JLMC’s) and non-union employee associations (NUEA’s), and financial participation schemes, such as profit sharing plans(PSP’s) and employee stock ownership plans (ESOP’s). By merging data from a new survey concerning HRMP’s among publicly-held Japanese firms with two other public data sources, we create for the first time a enterprise-level panel data set for Japanese firms that provides information annually for 1970-85 on both information sharing and financial participation. The data are then used to estimate translog production functions augmented by variables to capture the effects of information sharing and financial participation. The estimations yield the first econometric evidence on the productivity effects of diverse HRMP’s in Japan. The key findings include: (i) there are significant productivity-enhancing effects for JLMC’s, NUEA’s, PSP’s and ESOP’s; (ii) these productivity gains will change as HRMP’s age. For instance, the introduction of a JLMC boosts productivity initially by 9 percent annually.
