We report the first results for Japanese firms on the effects of clusters of participatory employment practices (or participation/employee involvement at the top level as well as at the grassroots level, and financial participation) by estimating production functions using new panel data. We find that the introduction of a group of complementary practices will lead to a significant 8–9 percent increase in productivity. However, the full productivity effect is felt only after a long developmental period.

Background: The Escherichia coli dinB gene is an SOS gene known to be required for l phage untargeted mutagenesis. When over-expressed, it exhibits a potent mutagenic activity without any exogenous treatment to damage DNA. Frameshift mutations at a run of identical bases are most enhanced. The product DinB is structurally related to the E. coli UmuC protein and the Saccharomyces cerevisiae Rev1 and Rad30 proteins, all of which are shown to be involved in bypass synthesis at a DNA lesion.

Executive turnover and its link to firm performance can provide a crucial measure of how effectively a firm solves the two sets of principal-agent problems: (a) the diverging interests between top management and shareholders, which may result in managerial entrenchment; and (b) the diverging interests between controlling shareholders and minority shareholders, which may lead to the expropriation of the latter by the former or "tunneling," as referred to in the literature. 1 Tying the personal fortune of top executives to the firm's performance aligns the interests of shareholders and those of management. It also breaks up the "insider" alliance between the controlling shareholder and management, thereby helping protect the interests of minority shareholders.Although there is a large literature on executive turnover in Western firms, research on executive turnover in non-Western firms is limited, and this paper is the only one on China. A closer look at the executive turnoverperformance link in China (one of the two major internal discipline mechanisms in corporate governance) is particularly relevant, since effective markets for corporate control are missing in China, the largest developing and transitional economy in the world. 2 Furthermore, China is an interesting case because both types of agency problems are acute due to poorly defined property rights and weak investor protection, which result largely from its command economy legacy.
