Firm age, size, and firm-level job creation and destruction

This study examines the effects of firm age and size on job creation and destruction of existing firms, using large-scale panel data from Japan. It contributes to the literature by examining the effects on firm-level job creation and destruction, differing from previous studies which focused on net employment growth (i.e., the difference between job creation and destruction for each firm) or job creation/ destruction on aggregated level (calculated by aggregating net employment increases/decreases of firms or plants). Results show that for an individual firm, age has significantly negative effects on the firm's job creation and destruction; however, size has a significantly negative effect on the firm's job creation but a significantly positive effect on its job destruction. Particular firm groups and different business cycles are further examined. The findings suggest that policy and managerial issues differ between a firm's expansion and aging.
