The transformation of the wage and performance appraisal system in a Japanese firm

This paper analyses how performance appraisal has affected the wages of employees in a unionized Japanese firm over time, using firm-level wage and performance appraisal data. Data show that the wage and performance-appraisal systems have been shifting to a performance basis, and away from the heavy reliance on age and seniority characteristic of the old systems. In the process, wage differentials among employees are becoming wider, particularly among those 37 to 41 years old and those 49 to 55 years old. Management introduced the new wage system through a process of concessionary bargaining. Surprisingly, employees, rather than the enterprise union, were able to convince management to modify their initial plans during bargaining over the new wage system.     

Effectiveness of Stochastic Neural Network for Prediction of Fall or Rise of TOPIX

Stochastic neural network is a hierarchical network of stochastic neurons which emit 0 or 1 with the probability determined by the values of inputs. We have developed an efficient training algorithm so as to maximize the likelihood of such a neural network. This algorithm enables us to apply the stochastic neural network to a practical problem like prediction of fall or rise of Tokyo Stock Price Index (TOPIX). We trained it with the data from 1994 to 1996 and predicted the fall or rise of 1 day ahead of TOPIX for the period from 1997 to 2000. The result is quite promising. The accuracy of the prediction of the stochastic network is the 60.28%, although those of non-stochastic neural network, autoregressive model and GARCH model are 50.02, 51.38 and 57.21%, respectively. However, the stochastic neural network is not so advantageous over other networks or models for prediction of the TOPIX used for training. This means that the stochastic neural network is less over fitting to the training data than others, and results in the best prediction. We will demonstrate how the stochastic neural network learns well non-linear structure behind of the data in comparison to other models or networks, including Generalized Linear model (GLM).JEL codes: D24, L60, 047     

The effects of external financing costs on investment timing and sizing decisions

We develop a dynamic model in which a firm exercises an option to expand production on either a small or large scale with cash reserves and costly external funds. An intermediate level of cash reserves, which is insufficient for the large-scale investment but sufficient for the small-scale investment, provides an incentive for the firm to invest early in the small-scale project. These results fill the gap between two types of results: (i) empirical findings of a U-shaped relation between the investment volume and internal funds and (ii) empirical predictions of a U-shaped relation between the investment timing and internal funds. In addition, our results have real-world implications for investment in alternative projects.     

Investment timing under debt issuance constraint

This paper examines the optimal investment timing decision problem of a firm subject to a debt financing capacity constraint. We show that the investment thresholds have a U-shaped relation with the debt capacity constraint, in that they are increasing (decreasing) with the constraint for high (low) debt issuance capacity. Although the financing constraint distorts investment timing, it may encourage the constrained levered firm to overinvest compared with the non-constrained levered firm. Our result fits well with the related problems involving the internal financing constraint.     

Resisting Japan's Neoliberal Model of Capitalism: Intensification and Change in Contemporary Patterns of Class Struggle

The Japanese model of capitalism has tended to be conceptualized within the extant literature in terms of a transition from a model characterized by coordination towards one in which neoliberal reforms have produced greater levels of instability, competition and inequality. This article argues that these trends raise the question of what patterns of resistance have been part of this transition. The article highlights how the neoliberalization of Japan's model of capitalism has also been accompanied by intensified class antagonism. Although the impact of such contestation on policymaking and actual policies has thus far been limited, Japan's neoliberalization has nevertheless been (and seems likely to remain) far from uncontested.     

Job Satisfaction,Work Time,and Well-Being Among Married Women in Japan

Abstract

This paper examines the relationship between paid work time and other time use of working married women with children in Japan and two aspects of well-being: job satisfaction and stress. The study demonstrates that rather than the amount of daily paid work time, both the gap between actual and desired work time and the intrinsic utility derived from paid work as an activity appear to be the key time-related variables affecting Japanese women's job satisfaction. The paper also shows that paid work time has multiple spillover effects on stress. It discusses the tradeoffs that married women with children in Japan make to stay in employment and the consequences for employer strategies and public policy.     

Wage and Performance Appraisal Systems in Flux: A Japan–United States Comparison

Unionized Japanese and American firms made changes in their wage and performance appraisal systems during the 1990s that were inspired by features of each others' traditional employment systems. Although Japanese firms made greater changes in the wage–setting process compared to American firms, outcomes in Japan changed little. Even with these changes, the wage and performance appraisal systems in the two countries retain distinctive characteristics. In the American firms'"segregation" between white– and blue–collar employees and high– and low–performers remains a feature of wage and performance appraisal systems; the Japanese system maintained its characteristic "integrated" form, but underwent moderate modifications.     

Research into ambidextrous R&D in product development – new product development at a precision device maker: a case study

Through research into new product development processes at a precision device maker, this paper discusses the skilful management of knowledge boundaries that lie between various organisations, and between specialised human skills and functions that make up a project organisation, and presents the ways in which new organisational capabilities are brought about for the development of new products as exploratory activities that dynamically merge and integrated the various knowledge within a company. This paper describes some of the implications derived from analysis and observations of the new organisational forms of the company's ambidextrous R&D management which the company uses to engage in both ‘uncertainty management (exploration)’ and ‘existing product management (exploitation)’, through the partnering of its existing formal organisations and dynamic structuring of diverse multifunctional teams formed as projects spanning different specialisations and capabilities.
