Debt, R&D investment and technological progress: A panel study of Japanese manufacturing firms' behavior during the 1990s

Based on a panel data set of Japanese manufacturing firms in research-intensive industries, we investigate quantitatively the extent to which outstanding debt affected firms' R&D activities during the 1990s. We find that massive amounts of outstanding debt had a significant, negative effect on R&D investment during that time. We also find that R&D expenditures were closely linked to firm-level total factor productivity growth over the same period. In fact, a ten-percentage-point increase in the debt–asset ratio lowered the rate of firm-level total factor productivity growth by 0.26 percentage points between 1999 and 2001, because it reduced R&D activities.
