Abstract
Beyond the general issue of institutional change at the aggregate level, some studies have shown that the diversity of Japanese firms has increased since the late 1990s, both in terms of performance and organization. This paper contributes to this literature by investigating the evolving employment practices at the firm level. In mobilizing a database of listed manufacturing firms, we focus on the evolution of the speed of downsizing between the 1990s and the 2000s. A specificity of our paper is that we do not limit our analysis to the introduction of individual effects but we rather resort to a Bayesian estimation procedure, which yields to (firm-specific) individual forecasts of the parameters of the adjustment process modelled with random coefficients. The first major result we get is a decreasing average speed of downsizing, contrary to what is found in a simple estimation with individual effects. Second, we confirm the increasing heterogeneity of Japanese firms between the 1990s and the 2000s, through a rising dispersion of the speed of downsizing. Third, we are able, from a descriptive viewpoint to identify some characteristics of firms with different speed of downsizing.
