Key research themes
1. How can the Malmquist Productivity Index be applied to assess total factor productivity changes in manufacturing industries?
This research theme explores the application of the Malmquist Productivity Index (MPI), a Data Envelopment Analysis (DEA) based method, to decompose total factor productivity (TFP) into technical efficiency changes and technological changes over time in manufacturing industries. It is essential as it allows assessment of both catching up effects (efficiency improvements) and frontier shifts (technological progress), providing actionable insights on operational and innovation performance.
2. What are the relationships between quality management practices and total factor productivity at the firm level?
This theme investigates how quality management (QM) factors impact total factor productivity (TFP) in industrial firms, seeking to empirically identify reliable QM predictors of productivity and understand their influence. This area matters because despite widespread QM adoption, inconsistent evidence exists regarding its direct effects on productivity, and clarifying this relationship can help firms allocate resources to effective QM practices for productivity gains.
3. How can stochastic frontier analysis and advanced econometric methods improve measurement of dynamic efficiency and total factor productivity in manufacturing?
This research area focuses on refining stochastic frontier models and incorporating econometric innovations such as Kalman filtering and time-varying inefficiency modeling to capture complex dynamic efficiency patterns and decompose TFP growth more precisely in manufacturing industries. Improved modeling addresses limitations of static or parametric assumptions, enabling better understanding of efficiency dynamics and productivity sources.
