Technical Inefficiency and Firm Behavior a Panel Study of Small and Medium Japanese Manufacturing Firms

This study examines the technical inefficiency of small and medium Japanese manufacturing firms by using panel data from the Basic Survey on Small and Medium Enterprises (2009-2018). We estimate the stochastic frontier production function with four production factors (regular workers, non-regular workers, capital stock and materials) and calculate the technical inefficiency of individual firms by applying a true random effects model that can distinguish technical inefficiency from firm heterogeneity. We find that inefficient firms are smaller, rely more on non-regular workers, exhibit poorer firm performance, have a higher debt-asset ratio, pay a lower interest rate and are inactive in capital investment and R&D investment. We also find that inactive capital investment and a high debt-asset ratio are mainly responsible for causing technical inefficiency
