Intellectual capital and total factor productivity

This paper defines total factor productivity as a function of a nation's intellectual capital. By developing a simple model, it explored the long-run relationship between intellectual capital and total factor productivity. The value of total factor productivity for each country was computed from Penn World Tables 10 using the residual method, and an index of intellectual capital was constructed from several indicators taken from world development indicators. Using a common correlated effect approach, a panel of 29 countries over 31 years was estimated using various dynamic macro panel models. The result confirmed the existence of a positive and significant link between total factor productivity and intellectual capital index. This implies that a potential source of productivity difference lies with a nation's research and development, human capital, processing, and marketing capabilities in boosting the general innovation process. Thus, national and regional development policies need to consider ways to improve broader innovation. Future research on total factor productivity needs to consider things outside the box.
